AB  - Coccidiosis is a significant poultry disease caused by the Eimeria species. This study aims to
determine the prevalence of Eimeria spp. on broiler farms in Vojvodina, along with the identification
of parasite species, and assess the implemented biosecurity measures. The study was conducted on
100 broiler chicken farms (28 small-sized; 34 medium-sized; 38 large-sized farms) from June 2018 to
December 2021. One pooled sample of faeces was collected from three to six-week-old chickens from
each farm, and assessment of biosecurity measures was carried out using a questionnaire. Using the
PCR method, DNA of Eimeria was found in 59 samples (59%), while 41 samples (41%) were negative.
Four species of Eimeria were identified, and their prevalence was the following: E. acervulina (37%),
E. maxima (17%), E. mitis (25%) and E. tenella (48%). A significant difference (p < 0.05) was established
in the number of oocysts in flocks from small-sized farms compared to medium-sized farms. It was
found that regular implementation of disinfection, disinsection and deratisation measures, as well as
all the biosecurity measures, can significantly reduce the occurrence of coccidiosis. These results will
help to develop better strategies for the control and prevention of coccidiosis on farms.

AB  - Commensal E. coli in the intestines of wild animals are not exposed to frequent direct
antimicrobial pressure, as is the case with commensal E. coli in the intestines of
domestic, especially farm animals and pets. The resistance of these bacteria in wild
animals was caused indirectly, that is, by human negligence and environmental
pollution, which allowed antibiotic-resistant bacteria to enter the food chain of wild
animals and birds. Consequently, in the bacterial intestinal flora of wild animals and
birds, there is nevertheless a selective pressure, which is responsible for the
persistence of resistance genes. This paper presents the results of the research on the
resistance of indicator E. coli to fluoroquinolones, which was conducted in the last
five years by the National Reference Laboratory for Antimicrobial Resistance in
Veterinary Medicine in Serbia. A high level of resistance to fluoroquinolones of
commensal E. coli was detected in wild boars, rabbits, roe deer and deer in hunting
grounds on the territory of the Province of Vojvodina. In addition to chromosomal
resistance, these bacteria also had plasmid-mediated resistance to fluoroquinolones
(PMQR). Resistance to fluoroquinolones was also discovered in commensal E. coli
from white-tailed eagles in the Gornje Podunavlje Special Natural Reserve, a part of
Bačko Podunavlje Biosphere Reserve, approved as a UNESCO Biosphere Reserve.
Also, resistance to fluoroquinolones of commensal E. coli was detected in Blackheaded gulls that feeding at the landfill of the city of Novi Sad. Very worrying the
high level of resistance to synthetic antibiotics, ie. to fluoroquinolone in the
population of wild animals and birds because these antibiotics are often the drug of
choice in the treatment of certain bacterial infections of humans and domestic animals.
Wild animals and birds are potential reservoirs of resistance genes and may be
responsible for dissemination of resistance in bacterial communities on our planet.

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  - Although Clostridium tertium is supposed to be a foodborne pathogen, the data on its detection in foodstuff s is scarce, and there are no reports on its isolation from feed. In this communication paper, the isolation of C. tertium from a sample of soya semolina is described. C. tertium may be importantin diff erential diagnosis, when it is to be distinguished from Clostridium perfringens. It is a unique species due to the lack of key characteristics of the genus it belongs to because it grows in the presence of oxygen and does not produce toxins. It has been well-documented as a human pathogen, although its mechanisms of pathogenicity are still unknown.

In this communication paper, the isolation of C. tertium from a sample of soya semolina is described. C. tertium may be importantin diff erential diagnosis, when it is to be distinguished from Clostridium perfringens. It is a unique species due to the lack of key characteristics of the genus it belongs to because it grows in the presence of oxygen and does not produce toxins.

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  - The infectious bursal disease virus (IBDv) is widespread in poultry flocks all around the world. Various biotypes have emerged and because of that, adequate management practices and vaccination of chicks are of paramount importance for the protection against field strains. One day old Lohmann Brown chicks were vaccinated with intermediate vaccines and the recombinant VAXXITEK HVT-IBDv vaccine formulation, and challenged at 48 days of life with the very virulent IBDv (vvIBDv) strain CH/99. The best protection (100%) was achieved with the recombinant vaccine administered by the subcutaneous or intramuscular route at a day old, while intermediate and intermediate plus vaccines protected 80% of birds from clinical symptoms. The highest bursa body ratio (5.33, 3.50 and 4.12) was accomplished in non-vaccinated and non-challenged birds and birds vaccinated with the VAXXITEK HVT-IBDv vaccine. The recombinant VAXXITEK HVT-IBDv vaccine has provided protection for commercial chicks against challenge with the vvIBDv strain in this experiment. Under field conditions, additional vaccination is possibly needed with supplementary application of live attenuated vaccines. However, the recombinant vector vaccines are providing significant aid against clinical signs and immunosupression caused by the vvIBDv.

AB  - Introduction: The aim of this study was to determine the prevalence of Salmonella along the slaughter line and to identify possible critical control points in one slaughterhouse facility located in the city of Belgrade. Methodology: In total, 700 samples were tested: two swabs from both sides of carcass were taken from each of 100 pigs. In this way, 200 pig skin swab samples were taken after stunning, 200 after processing and 200 after chilling. Additional 100 samples of ileal contents were also taken from the same pigs to obtain a collection of 270 isolates. All samples were analyzed using standard culture methods and serotyping. PFGE was performed for 27 isolates. Determination of antimicrobial resistance was performed by E-test. Results: In total, 47 (23.5%) swab samples were positive for the presence of Salmonella after stunning. After processing, Salmonella was isolated in two swab samples (1%), whereas all samples which were collected after chilling were negative for Salmonella. The sampling of ileal contents was positive for five Salmonella isolates (5%). The most frequently isolated serotypes were S. Derby (90.74%), S. Infantis (5.56%) and S. Typhimurium (3.7%). All tested isolates were resistant to tetracycline. Resistance was recorded to nalidixic acid (23.3%), ciprofloxacin (20%), ampicillin (10%) and chloramphenicol (14.4%), as well. The PFGE results indicated that isolates had a high genetic similarity. Conclusions: The investigation has confirmed that bacteriological examinations of carcass swabs, as well as ileal content, could be used to assess the carriage of salmonellae in pigs at the time of slaughter.

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.

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  - 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  - 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. Analizirali smo rezultate ispitivanja laboratorije za kliničku bakteriologiju. Od ukupno ispitanih bakterijskih infekcija iz kliničkog materijala u ovom petogodišnjem periodu, salmonele su izolovane u 7,3% slučajeva. Ustanovljeno je da je Salmonella infantis izolovana u 50,3% svih pozitivnih uzoraka, najčešće iz materijala dostavljenih sa farmi brojlerskih pilića. Salmonella enteritidis izolovana je u 48,2%, takođe najčešće kod brojlerskih pilića. Prisutan je trend porasta izolata Salmonella enteritidis i Salmonella infantis iz godine u godinu. Našim istraživanjem ustanovili smo da je najviše pozitivnih uzoraka bilo kod brojlera, u transportnim uginućima i uginućima iz prva tri dana starosti. Kod roditeljskih jata bilo je pozitivno 65 uzoraka u ovom petogodišnjem periodu (63 kod teške linije i 2 kod lake linije), što iznosi 8,03 % od svih pozitivnih izolata. Pretpostavlja se da je do infekcije salmonelama moglo doći usled horizontalne i vertikalne infekcije preko roditeljskih jata. .

The assessment of the importance and role of Salmonella organisms commonly detected in animal feed in epidemic outbreaks of salmonellosis is highly intricate. This is mainly due to the fact that isolates are rarely identified (typed) to the serovar level, thus, the relevant data on both animal feed and food of animal origin are lacking. In the framework of the 2-year project granted by the Ministry of Science and Technological Development of the Republic of Serbia, all Salmonella isolates originating from animal feed were typed to the serovar level in the National Reference Laboratory for Salmonella. Eighteen different serovars have been identified, whereas 15% of all isolates included serovar Montevideo. Frequent isolation of S. ser. Montevideo from animal feed originating from feed mills in our epizootic area (South Bačka and Srem district), encouraged our attempt to summarize and present the available data on the importance of Montevideo serovar in the outbreaks of clinical salmonellosis in humans and to review the reports on individual epidemiological studies aimed at detecting infection sources and establishing relevant facts on emerging antimicrobial resistance of Salmonella. Moreover, this article emphasizes the need and importance of an extensive Salmonella monitoring program at national level, which would encompass all links of the food chain including animal feed and feed processing plants as well.

AB  - The biological properties of an infectious bursal disease (IBD) virus isolated from bursas collected during an outbreak in a village chicken flock in Macedonia are described. The mortality rate was 50%. Two viruses coexisted in the bursas of infected chickens (IBDVwt and IBDVtc). The virus termed IBDVtc grows on chicken embryo fibroblast (CEF) cells from the first passage. Specific pathogen free chickens inoculated with IBDVtc at passage level 4 did not develop any clinical signs of disease. Some discrete bleeding on the leg muscles was seen and the bursa of Fabricius revealed pathological lesions similar to those caused by classical strains. However, the bursa recovered quickly (bursa lesion score 2) by 14 days post infection (PI). We also found evidence of bursal repopulation by means of perinuclear antigen staining. Strong CD3 influx was evident at 4 days PI, and at 33 days PI the CD3+ cell finding was comparable to the control. The mean antibody titre was 9.2 log(2) at 14 days PI. The amino acid composition of VP2 in IBDVwt (222 Ala, 242 Ile, 253 Gln, 256 Ile, 279 Asp, 284 Ala, 294 Ile and 299 Ser) is described. The same sequence was found in IBDVtc, except for two point mutations, at Gln253 -> His and Ala284 -> Thr. Such amino acid substitution is responsible for partial attenuation and the ability of the strain to replicate in cell culture. None of the commercial vaccine viruses has a similar arrangement of amino acids in the variable domain of IBDV. This strongly suggests that IBDVtc originates from a very virulent strain. To the best of our knowledge, this is the first report of a concomitant infection of chickens with highly pathogenic IBDV and its mutant counterpart.

AB  - In this paper are described the macroscopic, microscopic and immunophenotypic characteristics of tumors in Marek’s disease (MD). Liver, kidneys, lungs, heart, proventriclus, ovary and nerves of sciatic plexus collected from 20 chickens aged 8 to 24 weeks were examined. Lymphoproliferative enlargement in various organs of focal and diffuse character was found. The affected organs were enlarged, compact and very brittle, irregular in shape, grayish-red or grayish-white and of fatty consistency. Most often characteristic changes were in the spleen, liver, proventriculus and ovary that usually had a compact or ribbed, fatty cauliflower like formation, different in size. On histological examination proliferation of small and medium size lymphocytes, lymphoblast cells, Marek’s disease cells and activated reticulum cells were found. Tumor proliferates predominantly consisted of lymphoblasts and had all the characteristics of a lymphoma. Immunohistochemical analysis revealed that lymphoma cells in MD are of CD3 + phenotype. In liver proliferates numerous CD79+ cells were found perivasculary, which is an interesting finding demanding further research.
AB  - U ovom radu su opisane makroskopske, mikroskopske i imunofenotipske karakteristike tumora kod Marekove bolesti (MB). Ispitivanjem su bili obuhvaćeni jetra, bubreg, pluća, srce, žlezdani želudac, jajnik i nervi ishijadičnog pleksusa dvadeset pilića starosti između8i24 nedelje. U ispitivanom materijalu ustanovljeno je limfoproliferativno bujanje u različitim organima, fokalnog ili difuznog karaktera, pri čemu su zahvaćeni organi znatno povećani, kompaktni i veoma krti, često nepravilnog oblika, sivocrveni ili sivobeli, slaninastog izgleda. Najčešće i najkarakterističnije su bili promenjeni slezina, jetra, žlezdani želudac, jajnici koji obično predstavljaju kompaktne ili izbrazdane tvorevine poput karfiola, slaninastog izgleda i različite veličine. Histološki, u organima se nalaze proliferati malih i srednjih limfocita, zatim limfoblasta, ćelija Marekove bolesti i aktivisane retikulumske ćelije. Tumorski proliferati su predominantno sastavljeni od limfoblasta i imaju sve karakteristike limfoma. Imunohistohemijskom analizom je ustanovljeno da su ćelije limfoma kod MB predominantno T ćelijskog tipa, CD3 fenotipa. U proliferatu u jetri su nađene i brojne CD79 pozitivne ćelije lokalizovane perivaskularno, što predstavlja interesantan nalaz i zahteva dalja ispitivanja.
