AB  - Yersiniosis, one of the leading foodborne infections in the European Union, is caused by
Yersinia enterocolitica. In this study, the antibacterial and antibiofilm effects of cinnamon (Cinnamomum
zeylanicum Nees), clove (Syzygium aromaticum L.), oregano (Origanum vulgare L.), rosemary (Rosmarinus
officinalis L.), thyme (Thymus vulgaris L.), and winter savory (Satureja montana L.) essential oils were
investigated against Y. enterocolitica strains belonging to the bioserotype 4/O:3. Cinnamon essential
oil showed the highest antibacterial activity, with an MIC value 0.09 µL/mL, followed by oregano
and thyme essential oils, with MIC values from 0.09 to 0.18 µL/mL, and from 0.18 to 0.23 µL/mL,
respectively. Thyme essential oil at 0.23 µL/g (MIC) and at 0.46 µL/g (2MIC) significantly (p < 0.05)
reduced the number of Y. enterocolitica by 0.38 log CFU/g and 0.64 log CFU/g, respectively, in minced
pork meat during storage at 4 ◦C for 4 days. The Y. enterocolitica strains formed biofilms at 15 ◦C and
37 ◦C in tryptic soy broth and Luria–Bertani broth, while no biofilms were obtained at 5 ◦C, and in
meat broth nutrient media. Applying the minimum bactericidal concentrations of cinnamon, clove,
oregano, rosemary, thyme, and winter savory essential oils on preformed biofilms led to significant
reductions being observed in the range from 45.34% to 78.89%. A scanning electron microscopy
assay showed the devastating impact of oregano and thyme essential oils on the morphology of Y.
enterocolitica bacterial cells. In conclusion, the results of this study show that essential oils possess
high anti-Yersinia and antibiofilm effects.

AB  - Nocardia cyriacigeorgica је узрочник који се све чешће изолује у случајевима нокардиозе људи, међутим његова идентификација до нивоа врсте представља изазов за већину микробиолошких лабораторија. Инфекције изазване овом актиномицетом се релативно ретко сусрећу у ветеринарској клиничкој пракси при чему доступни литературни подаци обухватају мали број описаних случајева пиогрануломатозних лезија код животиња. Приказана студија описује случај тешког маститиса говеда на малом газдинству у Босни и Херцеговини изазваног узрочником N. cyriacigeorgica који је безуспешно третиран применом стандардне антибиотске терапије. С обзиром да изолат није идентификован применом конвенционалних микробиолошких техника, извршена је MALDI-ToF MS анализа чији су резултати били недовољно поуздани. У циљу утврђивања врсте анализирана је секвенца гена 16S субјединице рибозомалне рибонуклеинске киселине (16S rRNK). Наведени налаз је додатно потврђен применом технике секвенцирања више генских локуса (MLST) при чему су коришћене секвенце gyrB, 16S rRNK, secA1 и hsp65. Метода диск дифузије за испитивање осетљивости изолата N. cyriacigeorgica на антибиотике је примењена у складу са препорученим публикованим упутствима. Колико је ауторима познато, ово представља први случај маститиса говеда изазван узрочником N. cyriacigeorgica у Европи, али и први изолат Nocardia spp. пореклом од животиња за чију је идентификацију примењен MLST.
AB  - Although Nocardia cyriacigeorgica is recognized as a cause of human nocardiosis and is regarded as an emerging pathogen, many clinical laboratories find it difficult to identify this organism at the species level. The infections caused by this actinomycete are relatively uncommon in veterinary clinical practice, and the limited information currently available mostly relates to several cases of pyogranulomatous lesions in animals. We describe a case of severe bovine mastitis in a small holding in Bosnia and Herzegovina caused by N. cyriacigeorgica that did not improve after standard antibiotic therapy. The causative agent could not be identified using standard microbiological techniques and MALDI-ToF MS analysis was performed, yielding unclear results. Subsequently, the species N. cyriacigeorgica was confirmed by 16S rRNA sequence analysis, which was further validated by multilocus sequence analysis (MLSA) using the gyrB, 16S rRNA, secA1, and hsp65 sequences. The disc diffusion method was used to test for antibiotic susceptibility in accordance with published guidelines. To the best of our knowledge, this is the first report of N. cyriacigeorgica isolation from a clinical case of bovine mastitis in Europe, as well as the first time a strain of Nocardia spp. isolated from animals has been distinguished using the MLSA method.

AB  - It has been established that some clones of pathogenic bacteria such as Salmonella spp., Escherichia coli ST131, and methicillin-resistant Staphylococcus aureus (MRSA) tend to spread worldwide. Th erefore, epidemiological surveys have been conducted to identify the source of infection and to break the chain of infection. In this article, it was pointed out that common international clones of Salmonella are represented with the serotypes Typhimurium, Kentucky, Infantis and Enteritidis. Serovars Typhimurium and Kentucky display multidrug-resistant phenotypes more frequently. Several sequence types of E. coli and the international clone ST131 are described, including clades C1 and C2 with the extended-spectrum cephalosporinresistance genes (blaCTX-M-15 or blaCTX-M-27). Th ese pathogens are oft en found in both humans and animals. It is noted that Staphylococcus aureus became resistant to methicillin almost instantly aft er its introduction into clinical practice. Soon aft erwards, MRSA found its way to farm animals and wildlife. Th e cycles of infection are bidirectional: humans can disseminate MRSA in the environment but animals may also be sources of infection for humans. Comprehensive work has been done by epidemiologists to introduce all necessary measures to eliminate MRSA from hospitals. Also, much eff ort has been made in MRSA control to prevent infections on animal farms and contamination in the primary food production chain. As the struggle with pathogenic bacteria continues, we face the incessant threat of new resistance and virulence mechanisms, which bacteria use to resist the hostile environment and enhance their survival in their natural habitats including humans and animals. Th erefore, the capacity of certain bacteria to spread due to their virulence mechanisms and resistance phenotypes is presented, and a brief description of the research conducted in Serbia is included.

AB  - The results of the research into the microbiological contamination of litter used by broiler chickens are presented. Litter samples were taken prior to the introduction of chicks (day 0) and in 7-day intervals until the end of the fattening period. The total numbers of aerobic mesophilic microorganisms, yeasts, moulds and Clostridium perfringens spores, and the presence of bacteria of the Salmonella genus were determined. The total microbial count in newly laid litter was 7 log10 CFU/g, which increased to 9 log10 CFU/g by the 4th week. However, at the end of the 5th week, it was at the same level as in newly laid litter. C. perfringens spores, presumably originating from chicks' faeces, were first detected on day 7. In the next 7 days their number increased, reaching 3-4 log10 CFU/g, and remained at approximately same levels until the end of the research. The initial mould contamination was 5-6 log10 CFU/g. However, from day 21 moulds were not isolated, but only yeasts of the Saccharomyces genus. It is supposed that these were deposited with chicks' faeces, due to their presence in complete broiler feed. No bacteria of the Salmonella genus were ever isolated from the litter. In conclusion, the total numbers of microorganisms in deep litter reach their peak in approximately a month, which is followed by their decrease. Deep litter is a favourable environment for probiotic yeast cultures. Added to feed intended for broilers, they can positively influence the microbial composition of litter, providing healthier environment to fattening broilers.

Za 14 dana broj spora C. perfringens se povećao do 3-4 log10 CFU/g i na približno istim vrednostima zadržao do kraja ispitivanja. Sveža prostirka bila je kontaminirana plesnima u nivou od 5-6 log10 CFU/g, ali od 21. dana iz uzoraka prostirke nisu izolovane plesni, već samo kvasci roda Saccharomyces.

Rezultati ispitivanja pokazuju da ukupan broj mikroorganizama u prostirci dostiže svoj pik za oko mesec dana, nakon čega se smanjuje. Prostirka je pogodna sredina za život probiotskih kultura kvasaca i njihovo dodavanje u smeše za tov brojlera može imati povoljan uticaj na sastav mikroorganizama u prostirci, a time i obezbeđenje zdravije životne sredine u podnom sistemu uzgoja brojlera.

AB  - Necrotic enteritis (NE) or poultry clostridiosis is a disease which poses enormous health problems and makes tremendous economic losses to intensive poultry production worldwide. Despite having been targeted in extensive research for decades, a number of aspects of its pathogenesis remain unknown. For more than 30 years alfa-toxin has been considered to be the main virulence factor of the causative agent, but experimental research using a mutant Clostridium perfringens strain lacking the gene coding for this confirmed that alpha-toxin is not necessary for pathogenesis. Since the 1980s, NetB toxin has been the main suspected virulence factor. However, recently it has been discovered that the large clostridial cytotoxin named TpeL also contributes to the pathogenesis of NE. In spite of that, the prevalence of the genes which code for these toxins vary between the isolates of C. perfringens from the intestines of diseased poultry, which made clear that further investigation into their roles is necessary.

abstract = "Necrotic enteritis (NE) or poultry clostridiosis is a disease which poses enormous health problems and makes tremendous economic losses to intensive poultry production worldwide. Despite having been targeted in extensive research for decades, a number of aspects of its pathogenesis remain unknown. For more than 30 years alfa-toxin has been considered to be the main virulence factor of the causative agent, but experimental research using a mutant Clostridium perfringens strain lacking the gene coding for this confirmed that alpha-toxin is not necessary for pathogenesis. Since the 1980s, NetB toxin has been the main suspected virulence factor. However, recently it has been discovered that the large clostridial cytotoxin named TpeL also contributes to the pathogenesis of NE. In spite of that, the prevalence of the genes which code for these toxins vary between the isolates of C. perfringens from the intestines of diseased poultry, which made clear that further investigation into their roles is necessary. It has been agreed that specific intestinal environmental conditions, which favour the growth and multiplication of C. perfringens, are key factors to the emergence of disease. Given that a battery of non-specific factors contributes to pathogenesis, as well as that it is impossible to eliminate them in intensive poultry production, not much hope remains that NE can be controlled.

AB  - The presence of Listeria monocytogenes was evaluated in a small-scale meat processing facility in Montenegro during 2011-2014. L. monocytogenes isolates from traditional meat products and environmental swabs were subjected to a) molecular characterization b) serotyping by both multiplex PCR and next generation sequencing (NGS) c) potential antimicrobial resistance (AMR) was assessed by extraction of specific genes from NGS data and d) screening for the presence of some disinfectant resistance markers. Overall, traditional meat products were contaminated, most likely from incoming raw materials, with 4 major specific STs of L. monocytogenes (ST515, ST8, ST21, ST121) representing 4 clonal complexes (CC1, CC8, CC21, CC121) identified during the four-year period. These strains belonged to serogroup IIa which predominated, followed by IVb (ST515, CC1). The strains from environmental swabs belonged, exclusively, to ST21 and were isolated from cutting board and floor swabs in 2011. Furthermore, we found Tn6188, a novel transposon conferring tolerance to BC, to be specific to sequence type ST121. In addition, antimicrobial resistance genes mprF and fosX were present in clonal complexes CC21 and CC121, while complexes CC8 and CC1 exclusively harbored the mprF antimicrobial resistance gene.

AB  - The aim of the study was to characterize multidrug-resistant (MDR) Escherichia coli isolates collected in Serbia from bovine clinical mastitis cases and diseased pigs, mainly with molecular methods. A total of 48 E. coli isolates was collected during the years 2013-2014, of which 22 were MDR and were included in further analysis. Phylogenetic typing showed that 17 isolates belonged to group A, while two isolates were classified in group B1 and a single one in group D. All isolates showed unique macrorestriction patterns. Phenotypic susceptibility testing revealed resistances of the isolates against up to 13 antimicrobial agents, including resistance to fluoroquinolones. A wide variety of resistance genes was detected by PCR amplification and sequencing of amplicons. Sequence analysis of the quinolone resistance determining regions of topoisomerase genes revealed mutations in gyrA, parC, and/or parE. Plasmid-mediated quinolone resistance genes were detected in two porcine (aac-6-Ib-cr and qnrS, respectively) isolates and a single bovine (aac-6-Ib-cr) isolate. Resistance genes were found to be located on conjugative plasmids in 16 cases, many of which conferred a multidrug resistance phenotype. In conclusion, the plentitude of resistance genes located on conjugative plasmids and integrons in E. coli from cows and pigs in Vojvodina, Serbia, pose a high risk for horizontal gene transfer in bacteria from livestock husbandry.

AB  - In the present paper the laboratory isolation and identification of Bordatella bronchiseptica, the causative agent of canine tracheobronhitis, is described. A dog which suffered persistent cough, loss of appetite and fever was previously unsucceffully treated with antibiotics, which is why nasal swabs were taken and sent for microbiological assessment. The isolation of the causative agent was performed on routinely used standard solid growth mediums. The final identification of the isolate was done with MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight) and real-time PCR (polymerase chain reaction) assays. Therapy based on the results of the antibiogram lead to successful recovery. The necessity of cooperation of veterinary clinicians and veterinary microbiologists for timely and reliable identification of the microbe(s) and selection of antimicrobials based on the results of the susceptibility testing is emphasized. The significance of the collaboration between microbiological veterinary laboratories and those dealing with human material is underlined. These can provide precise identification of zoonotic agents.

AB  - Clostridium perfringens is a Gram-positive, endospore-forming, anaerobic rod, ubiquitous in nature. C. perfringens strains can produce about 17 toxins. Many of them can lead to miscellaneous diseases, among which the enteric ailment may be the most common and is of utmost importance. In the present work 34 strains of C. perfringens isolated from feed and one from a cow suspected to have died of clostridial infection were subjected to molecular analysis. In order to detect the genotypes, the following genes coding for toxins were targetted: cpa, cpb, cpb2, cpe, etx and iap. The multiplex PCR assay revealed that all C. perfringens isolates from animal feed were of type A and b2-toxinogenic type A strains, possessing only the cpa (n=21), or both the cpa and the cpb2 genes (n=13). The importance of C. perfringens toxins α and β-2 in the pathogenesis of enterotoxemia is discussed and the regulation on the detection of this bacteria in animal feed questioned. The use of PCR in practise could enable the toxin-genotyping of C. perfringens isolates and, thus, provide a real basis for the establishment of maximum acceptable limits of this bacteria in feed.

C. perfringens je uzročni agens različitih oboljenja (sindroma), ali su crevne infekcije/intoksikacije najčešće i od najvećeg značaja za zdravlje farmski gajenih životinja.

AB  - Pasteurella (P.) multocida is a heterogeneous species of Gram-negative bacteria which are common commensals of the upper respiratory system of various mammal and bird species, but are also opportunistic contagious zoonotic pathogens which cause a wide spectre of infections in domestic animals and humans. P. multocida is a rare cause of mastitis in dairy cows. The source of infection mainly remains unknown, mastitis usually is acute, and the therapy by intramammary administration of antibiotics does not lead to satisfactory results. Lethality is possible due to presence of endotoxins in blood. Literature data on P. multocida mastitis in dairy cows is particularly scarce, which is why such a case is described in the current work, with past medical history, clinical findings, laboratory diagnostics and therapeutic approach.

AB  - Introduction. Bacteria isolated from skin, gills, and fish intestines from aquaculture ponds, ornamental fish stores/aquariums and live fish markets were investigated. Materials and Methods. Disk diffusion and E-test were used for susceptibility testing to carbapenems, ureidopenicillins with or without ß-lactamase inhibitor, 3rd and 4th generation cephalosporins, aminoglycosides, colistin, fluoroquinolones, and chloramphenicol. PCR was used to detect resistance genes in the bacterial isolates. Results and Conclusions. Among the total number of bacteria tested, regardless of the genus and species, 56.7% of isolates were found to be sensitive to all antibiotics, 23.1% of isolates were resistant to one or two antibiotics, and 20.2% of isolates were resistant to three and up to 16 antibiotics. In A. hydrophila isolated from a guppy (Poecilia reticulata) sampled in an ornamental fish store aquarium, 16S rRNA methyltransferase was confirmed by finding the rmtB gene. Pseudomonas isolates showing phenotypic resistance to carbapenems, ureidopenicillins with or without ß-lactamase inhibitor and 3rd and 4th generation cephalosporins were tested and found negative for different resistance genes by PCR (MßL, ESBL, KPC, OXA-23, OXA-24, OXA-40, OXA-58, VIM, IMP, SPM, GIM, NDM, TEM, SHV, CTX-M-1, CTX-M-9, OXA-1, OXA-9 and the AmpC group, as well as single genes, MOXM, CITM, ACCM, EBCM, FOXM, DHAM). Based on E-test results, three Pseudomonas isolates from common carp (Cyprinus carpio) were found to be resistant to colistin with MIC values of 4 μg/mL.
AB  - Uvod. U ovom ispitivanju izolovane su bakterija koje su sastavni deo mikrobioma kože, škrga i creva riba iz različitih sredina (ribnjaci, akvarijumi, riblje pijace). Materijal i metode. Primenom disk difuzionog testa i E testa ispitivano je fenotipsko ispoljavanje rezistencije na karbapeneme, ureidopeniciline sa i bez inhibitora beta-laktamaza, cefalosporine III i IV generacije, aminoglikozide, tetraciklin, kolistin, flurohinolone i hloramfenikol. Prisustvo gena rezistencije vršeno je primenom metode PCR. Rezultati i zaključak. Posmatrano na ukupan broj ispitanih sojeva, bez obzira na rod i vrstu bakterija, 56,7% sojeva je osetljivo na sve antibiotike, 23,1% sojeva je rezistentno na 1 do 2 antibiotikaa 20,2% sojeva je rezistentno na 3 do 16 antibiotika. Kod soja A. hydrophila izolovanom iz akvarijumske ribice gupi nalazom gena rmtBpotvrđeno je prisustvo 16S rRNK metiltransferaze odgovornim za rezistenciju na aminoglikozide. Pseudomonas izolati koji su pokazali fenotipsku rezistenciju na karbapeneme, ureidopeniciline sa i bez inhibitora beta-laktamaza, kao i na cefalosporine III i IV generacije, testirani su i bili negativni na sledeće gene (MßL, ESBL, KPC, OXA-23, OXA-24, OXA-40, OXA-58, VIM, IMP, SPM, GIM, NDM, TEM, SHV, CTX-M-1, CTX-M-9, OXA-1, OXA-9, AmpC grupni kao i pojedinačni geni, MOXM, CITM, ACCM, EBCM, FOXM, DHAM). Na osnovu dobijenih rezultata primenom E testa, kod 3 soja iz roda Pseudomonas izolovanih od šarana nađena je rezistencija na kolistin sa dobijenim vrednostima MIK 4 μg/mL.

AB  - The aim of the present study was to determine the porcine circovirus type 2 (PCV2) prevalence in boars in 3 farms in Serbia and their possible relation with alterations of reproductive parameters and blood biochemical parameters [total protein, urea, creatinine and aspartate transaminase levels (AST)]. The prevalence of (PCV2) was evaluated by the presence of specific antibodies. An ELISA assay was used for the detection of PCV2 antibodies in 58 boars' blood sera from Serbian commercial farms, among which 48 were from and reared in the Serbian farms, and 10 were imported from different European Union (EU) countries. Anti PCV2 IgM and/or IgG were detected in sera of 51 (87.93%) boars. Based on the type of antibodies (IgM and IgG PCV2 antibodies), it was concluded that chronic PCV2 infection was the predominant type in tested boars. The imported boars did not have an active infection titer. Biochemical tests in blood didn't show significant differences between PCV2 positive and negative boars. The recorded high prevalence of PCV2 antibodies among boars indirectly proved that PCV2 has been wide spread in the examined farms. Significant difference in the frequency of active, recent and chronic PCV2 infection in boars was found among three farms (p  lt  0.05). Imported boars did not show significant difference in terms of active, recent or chronic PCV2 infection in comparison with boars deriving from Serbian farms (p > 0.05). Among boars of three different breeds (Landrace, Duroc and Yorkshire), a significantly higher prevalence of PCV2 antibodies was revealed in Landrace boars (p=0.003). Reproductive parameters of sows that were inseminated with PCV2 positive or negative boars' semen, showed similar farrowing rate, as well as percentage of live and stillborn piglets, thus indicating that the observed chronic PCV2 infection did not affect significantly the breeding capability of boars.

AB  - Bacteria belonging to the genus Salmonella are one of the major foodborne pathogens, primarily due to their health and economic impact. The main sources of human infection are poultry products. Salmonella may enter various stages of the poultry production process in many different ways. Biofilm is just one of the recently recognised risk factors, which significantly contributes to the persistence of these bacteria in poultry premises, hatchery cabinets, transportation vehicles, and food and feed factory environment. The control of Salmonella in poultry production is a highly complex and challenging process, additionally complicated by the fact that to date no efficient methods have been developed to eliminate biofilms or prevent their formation. In vitro investigations revealed that the ability to produce biofilm varies between Salmonella serovars, strains of the same serovar and under various environmental conditions. This paper briefly summarises literature data concerning biofilms produced by Salmonella serovars and their influence on the efficacy of control and eradication strategies in the poultry production chain.

AB  - For decades intensive husbandry has more or less been based on the use of antibiotics in sub-minimum inhibitory concentrations (sub-MIC) aimed at growth promotion. Continuous exposure of animal intestinal microbiota, including opportunistic zoonotic pathogens, to sub-MIC poses a pressure to selection and spread of bacteria strains with developed mechanism of antibiotic resistance. These bacteria may be transferred to people either by direct contact with farm animals or indirectly, via the food chain. Although in the EU a ban on the use of antibiotics as growth promoters was imposed in 2006, in many countries, including the largest producers and consumers of antibiotics in the world, it has yet to be done. Given that we are faced with a global problem of the loss of the efficacy of several antibiotic classes which are available for the treatment of human bacterial infections, it is unacceptable that antibiotic use in husbandry is not under global control. Reduction in antibiotic use in clinical practice in human medicine remains in dispute, but non-therapeutic use in husbandry remains a field in which much can be done to contribute substantially to the extension of antibiotic effectiveness and health care of future generations.

Na ljude se ove bakterije mogu preneti direktnim kontaktom sa farmskim životinjama ili na posredan način, preko lanca ishrane. Iako je u zemljama Evropske unije upotreba antibiotika za promociju rasta životinja zabranjena 2006. godine, u mnogim državama, uključujući najveće proizvođače i potrošače antibiotika u svetu, ova praksa se zadržala do danas. Gubitak efikasnosti antibiotika koji su trenutno na raspolaganju za lečenje bakterijskih infekcija kod ljudi je rastući problem, zbog čega je neprihvatljivo da upotreba antibiotika u stočarskoj proizvodnji nije pod globalnom kontrolom. Klinička praksa u humanoj medicini ostavlja diskutabilan prostor za redukciju primene antibiotika, ali je neterapeutska upotreba u stočarstvu oblast u okviru koje se može značajno doprineti produžavanju veka upotrebljivosti pojedinih klasa antibiotika i očuvanju zdravlja budućih generacija.

AB  - All natural antibiotics available to modern medicine are products of soil-dwelling bacteria and fungi. In addition, all resistance genes which are being detected in human pathogens existed in soil bacteria even before antibiotics were discovered and brought into use. However, the concentrations of natural antibiotics in soil are usually subinhibitory - insufficient for the selection of resistant subpopulations of microorganisms. The consumption of organic fertilisers for agricultural soil amendment increases proportionally to the consumers' growing demand for organically produced food. Manure originating from industrial pig, cattle and poultry farms is not only the source of nutrients which stimulate the vital functions of soil microorganisms, but also of antibiotics and bacteria harbouring various resistance mechanisms. The application of organic fertilizer leads to disruption of the natural balance between bacterial communities in the soil through several mechanisms, and influences the increase in the prevalence of resistance genes and promotes their horizontal transfer. Whether as-yet-unknown resistance genes in soil bacteria may pose threat to human health if transferred from commensal bacteria in the environment to pathogen species, or migrate to clinical settings via food chain or in some other possible route - remains an open question.

AB  - Introduction: Novel molecular techniques applied in biotechnology research have provided sound evidence on clonal persistence of distinct serovars of Salmonella in feed factory environments, over long periods of time (months, even years), which can be responsible for repeated in-house contamination of final products. In this study, we examined the possibility of clonal persistence of isolates of three Salmonella serovars that have been repeatedly identified in animal feed samples from three feed factories throughout a two-year period. Methodology: The isolates Salmonella enterica serovars Tennessee (n = 7), Montevideo (n = 8), and Infantis (n = 4) were tested for genetic diversity using pulsed-field gel electrophoresis (PFGE) and multicellular behavior patterns by applying the Congo red agar test. Results: SpeI and XbaI macro-restriction profiles indicated that isolates S. Montevideo and S. Infantis were identical, whereas isolates of S. Tennessee demonstrated greater genetic diversity, although the genetic differences did not exceed 10%. All Salmonella serovars demonstrated the ability to produce predominant matrix compounds essential for biofilm formation, curli fimbriae and cellulose. Conclusions: The identification of identical clones of S. Montevideo and S. Infantis, as well as the minor genetic diversity of S. Tennessee, which have been repeatedly isolated from animal feed in three production plants throughout a two-year period, indirectly suggests the possibility of their persistence in feed factory environments. Their ability to express the key biofilm matrix components further supports this hypothesis.

AB  - Increased incidence of protothecal mastitis has been recorded in several countries in the past ten years. The main goal of this article is to draw the attention of scientific and professional community to the emerging issue of mammary protothecosis. The article collates currently known facts about infection reservoirs, predisposing factors for the development of mastitis, clinical manifestations of the disease, and potential transmission routes within the herd as well as the measures for control and eradication. We would like to point out that identification of protothecal mastitis on a dairy farm is associated with a range of problems. Early detection of infected animals can be difficult because of predominantly subclinical course of early-stage infection, which easily spreads between cows via the milking system. Spontaneous recovery has not been recorded and infected cows typically develop chronic mastitis with granulomatous infiltration and progressive loss of functional parenchyma of the mammary gland. Substantial economic losses and health damages associated with mammary protothecosis strongly emphasise the need for developing effective prevention strategies aimed at control of the infection.

AB  - Resistance to tetracycline was studied in Salmonella Infantis isolated from 28 poultry farms in the Northern part of Serbia (The Autonomous Province of Vojvodina). A total of 18 isolates were resistant to nalidixic acid (NAL) and tetracycline (TET). The minimal inhibitory concentration (MIC) to TET, ranged from 1-256 mg/L. Namely, 13 isolates exhibited MIC to TET at 256 mg/L, in four of the isolates, the MIC was 128 mg/L and one isolate had MIC 64 mg/L. Ten isolates were exhibiting a MIC of 1mg/L. It was evident that Salmonella Infantis had also spread to breeders and layers. In this work, we detected the tetA gene and the corresponding tetR gene (encoding the repressor protein) as well as the truncated transposon Tn1721, which are responsible for the resistance to TET. The presence of the non conjugative transposons from the conjugative plasmid has facilitated the spread of resistance to TET in Salmonella. It was concluded that higher biosecurity practice in poultry farming presents the best option to eliminate infections caused by Salmonella spp. from poultry flocks in Serbia. A rational use of antimicrobials is necessary to prevent any further spread of Salmonella Infantis resistant clones.

AB  - Salmonella causes local and systemic infections of poultry, which may lead to substantial direct and indirect economic losses, presenting also significant risk to human health. The aim of this study was to monitor the occurrence of certain serotypes of Salmonella spp. isolated on poultry farms in Southern Bačka and Srem regions in the period from 2010 to 2014, as recommended by the Book of rules of early detection, diagnostic, prevention of spreading and eradication of Salmonella spp. We analyzed the results obtained from the laboratory for clinical bacteriology to determine number of salmonella cases. From all samples that have been submitted for bacteriology analysis, salmonellas were isolated from 7.3% samples. Salmonella infantis was isolated from 50.3% of all salmonella-positive samples, mostly from materials supplied from broiler farms. Salmonella enteritidis was most frequently isolated in broiler chickens at the rate of 48.2%. There is an increasing trend in the occurrence of Salmonella enteritidis and Salmonella infantis on poultry farms from year to year. Our research revealed the highest incidence of salmonella isolates in broilers that died during transportation or within the first three days upon arrival of chickens. During the five-year research period, 65 samples from parent flocks (63 from broiler breeders and 2 from parent flocks of layers) were salmonella positive, which makes 8.03% of all positive isolates. It is most likely that salmonella infection occurs due to infection of parent flocks and young chickens are infected trough both vertical and horizontal transmission. .

Cilj ovog rada bio je monitoring određenih sojeva Salmonella spp. propisanih Pravilnikom o utvrđivanju mera za rano otkrivanje, dijagnostiku, sprečavanje širenja, suzbijanje i iskorenjivanje infekcija živine određenim serotipovima salmonella, na teritoriji Sremskog i Južnobačkog okruga u periodu od 2010. do 2014. godine.
