AB  - Current estimates predict that due to population growth by 2050, the world will need
about 70% more food than is currently being produced. With the growth of the population whose diet also requires protein intake, livestock production will continue to grow,
and proteins of animal origin will remain an important part of the population’s diet. The
production of proteins of animal origin will increase in the future mainly due to the increased production of pork and poultry meat. Therefore, the demand for protein in feed
will increase, as pigs and poultry have a greater need for protein in feed compared to
ruminants. Therefore, the needs and challenges for nowadays are to find those sources
of protein that will satisfy the nutritional needs of the largest part of the population
and animals, and for which production will be cheaper and more accessible than for
the sources of protein that are currently used in human and animal nutrition. To date,
several new sources of protein for human and animal nutrition are already in use, and
their importance will be even greater in the future. Insects, proteins from single-celled
organisms and algae are increasingly used as alternative protein supplements. In addition, microbial technology and biological fermentation can improve the digestibility
and, thus, the utility value of protein supplements.

AB  - Milk plays a significant role in human nutrition, and more than 6 billion people worldwide con‑
sume milk and dairy products. In 2019, total milk production in Serbia reached 1,597 million
litres, cow’s milk accounting for almost 95%. Out of the total amount of cow’s milk produced in
2021, 58.2% was purchased. The share of milk delivered to dairies increased by over 50% in the
previous decade. The results in the dairy sector are directly influenced by dairy cattle farming
in Serbia, which has been experiencing a decrease, but there has been a consistent increase in
milk yield over the past few years. Production of dairy products in Serbia recorded a decrease
during the last ten years, except for dry products (cream powder, whole and partially‑skimmed
milk powder), which recorded an increase. Trade in dairy products is very volatile, as dairy
trade flows can be affected by the overall economic situation in a country, fluctuations in supply
and demand, changing exchange rates and political measures. The largest dairy product trade in
Serbia is conducted in milk and cream, followed by cheese, and then milk and cream powder.

domaćinstvima na istoku Srbije (Stara planina), jugozapadu (Pešterska visoravan) i na području Vojvodine (Subotica, Senta, Čoka, Sremska Mitrovica,
Deliblatska peščara). Odlikuju se izuzetnom prilagodljivošču, plodnošću i
otpornošću na bolesti. U Srbiji postoje dve autohtone rase ovaca: pramenka i
cigaja. Pramenka predstavlja jedinstvenu genetičku baštinu koja postoji hiljadama godina i kao takva je važan element regionalne agro-bioraznolikosti,
tradicije i kulturne baštine Srbije. Pramenka ima 11 sojeva, a najpoznatiji su:
sjeničko-pešterski, svrljiški, pirotski, krivovirski, karakačanski, lipski, šarplaninski, bardoka i vlaško-vitoroga. Postoje razlike u prinosu mleka različitih
sojeva pramenke. Najmlečniji soj pramenke je bardoka, koja tokom laktacije
daje prosečno 200 litara mleka. Takođe, utvrđene su razlike i u sastavu mleka,
pri čemu mleko bardoke može imati i do 7,1% mlečne masti, dok su nešto niže
vrednosti utvrđene kod lipske pramenke. Najviši procenat proteina utvrđen je u
mleku vlaško-vitoroge pramenke. Najpoznatiji sojevi cigaje su somborska i
čokanska. Čokanska cigaja u toku laktacije od 120 dana daje prosečno 120
litara mleka, sa sadržajem mlečne masti od 5 do 8%. Status ugroženih sojeva u

AB  - Gama-aminobuterna kiselina (GABA) je široko rasprostranjena neproteinska
aminokiselina, koja ima funkciju glavnog inhibitornog neutrotransmitera u
centralnom nervnom sistemu sisara. Osim osnovnog, neuromodulatornog efekta,
GABA ima i druge fiziološke funkcije, kao što su antidiuretičko i antihipertenzivno
delovanje. Poslednjih godina, mnoga istraživanja su fokusirana na mikroorganizme
koji imaju sposobnost produkcije GABA, kako u svrhe biosinteze za potrebe
farmaceutske industrije, tako i za potencijalnu primenu u prehrambenoj industriji u
cilju dobijanja funkcionalne hrane. U tom pogledu, naročito se ističe potencijal
upotrebe bakterija mlečne kiseline (BMK). Glutamat-zavisni sistemi BMK imaju
biološku funkciju kao vid strategije preživljavanja nepovoljnih uslova sredine, usled
pada pH, koji nastaju tokom fermentacije ugljenih hidrata i nakupljanja mlečne
kiseline. Kod BMK, reakcija dekarboksilacije glutamata prisutnog u medijumu u GABA,
katalizovana je enzimom glutamat-dekarboksilazom, uz prisustvo kofaktora
piridoksal-5’-fosfata. Fermentisani proizvodi od mleka i sirevi predstavljaju značajan
izvor GABA-produkujućih sojeva BMK, s obzirom da brojni pripadnici BMK,
prevashodno iz rodova Lactobacillus, Lactococcus i Streptococcus poreklom iz mleka i
proizvoda od mleka na hromozomu poseduju gad operon koji kodira sintezu
glutamat-dekarboksilaze. GABA-produkujuće BMK imaju veliki potencijal za
korišćenje u proizvodnji funkcionalnih proizvoda od mleka. Ovaj pregledni rad ima za
cilj da pruži uvid o dosadašnjim istraživanjima GABA-produkujućih BMK poreklom iz
mleka i proizvoda od mleka, kao i o daljem toku istraživanja, ali i potencijalima
primene BMK u dobijanju funkcionalne hrane.

AB  - The potential risk to human and animal health provides a rationale for research on
methicillin-resistant staphylococci (MRS) and mammaliicocci (MRM) in dairy herds. Here, we
aimed to estimate their occurrence in the bulk tank milk (BTM) samples collected in 2019–2021 from
283 bovine dairy farms in the Belgrade district. We used whole-genome sequencing to characterize
the obtained isolates and assess their genetic relatedness. A total of 70 MRS/MRM were recovered,
most frequently Staphylococcus haemolyticus and Mammaliicoccus sciuri. Five clusters of 2–4 genetically
related isolates were identified and epidemiological data indicated transmission through, e.g., farm
visits by personnel or milk collection trucks. Most MRSA isolates belonged to the typical livestockassociated
lineage ST398-t034. One MRSA isolate (ST152-t355) harbored the PVL-encoding genes.
Since MRS/MRM isolates obtained in this study frequently harbored genes conferring multidrug
resistance (MDR), this argues for their role as reservoirs for the spread of antimicrobial resistance
genes. The pipeline milking system and total bacterial count >100,000 CFU/mL were significantly
associated with higher occurrences of MRS/MRM. Our study confirms that BTM can be a zoonotic
source of MRS, including MDR strains. This highlights the urgent need for good agricultural practices
and the continuous monitoring of MRS/MRM in dairy farms.

ethically sourced food. The food industry strives to meet these demands without compromising
food safety. Non-thermal technologies offer a solution by using different physical
hurdles to ensure microbiological safety and extended shelf life. In the dairy industry,
high-pressure processing, ultrasound, ultraviolet processing, cold plasma and pulsed
electric fields show promise as effective non-thermal technologies. These methods achieve
microbial inactivation by altering cell membrane structures and damaging genetic material,
although the specific mechanisms may vary. Moreover, non-thermal technologies have
the potential to enhance product quality and facilitate the development of functional dairy
products, with high-intensity ultrasound and supercritical carbon dioxide as particularly
noteworthy. Despite the expanding research and development in the field of non-thermal

Tako aktivirani mogu imati uticaj na različite fiziološke i metaboličke funkcije u organizmu ljudi, kao što su antimikrobna, antioksidativna, antihipertenzivna, antitrombotična, imunomodulatorna, anticitotoksična aktivnost i druge. Antimikrobno dejstvo bioaktivnih peptida je važan deo nespecifičnog imuniteta, posebno na površini sluzokože tankog creva. Takođe, bioaktivni peptidi imaju sposobnost da podstiču aktivnost antioksidativnih enzima (katalaze, superoksid dismutaze i glutation peroksidaze), mogu imati antiinflamatorno dejstvo, kao i da podstiču lučenje insulina. Zbog brojnih različitih pozitivnih efekata na zdravlje ljudi, modulacijom ili poboljšanjem fiozioloških funkcija, proteini mleka, kao izvor bioaktivnih peptida, imaju potencijal za komercijalnu upotrebu u proizvodnji kako konvencionalne, tako i funkcionalne i medicinirane hrane ili dijetetskih suplemenata. Međutim, s obzirom da su rezultati većine istraživanja dobijeni u in vitro uslovima, postoji potreba za istraživanjima in vivo kako bi se u potpunosti ispitalo dejstvo bioaktivnih peptida na različite fiziološke funkcije.

AB  - U poslednje vreme postoji povećano interesovanje za mleko magarica, pre svega kao alternativom za majčino mleko kod dojenčadi sa alergijom na proteine kravljeg mleka, ali i s obzirom da postoji grupa potrošača koja ga konzumira zbog proklamovanih pozitivnih efekata po zdravlje. Takođe, interesovanje naučne zajednice je usmereno i na očuvanje autohtonih rasa kopitara u cilju zaštite biodiverziteta i genetičkih resursa. Higijena muže može da ima važan uticaj na kvalitet i bezbednost mleka magarice, a naročito zbog toga što se mleko magarica konzumira sirovo i da ne postoji smanjenje ili eliminacija kontaminacije primenom termičkih tretmana. U cilju procene higijenskih uslova muže magarica, u okviru ovog istraživanja su praćena tri parametra: ukupan broj aerobnih mezofilnih bakterija, broj Enterobacteriaceae (pri 37 °C i 44 °C) i broj koagulaza pozitivnih stafilokoka. Ispitivanja su izvršena primenom standardnih ISO metoda koje se koriste u mikrobiologiji hrane. Materijal su predstavljala 33 uzorka mleka magarica, prikupljena sa 6 farmi muznih magarica u Srbiji. Sve farme sa kojih su uzorci prikupljeni, su porodična gazdinstva na kojima se životinje gaje u ekstenzivnim uslovima ili poluintenzivnim uslovima. Na svim farmama se primenjuje ručna muža i prilikom pripreme životinja za mužu, vime se ne dezinfikuje, već samo pere mlakom vodom i zatim osuši papirnim ubrusom. Nakon muže, mleko se procedi kroz gazu i prelije u plastičnu ambalažu, a zatim čuva pri temperaturama hladnog lanca ili se zamrzava do prodaje i kao sirovo se konzumira. Rezultati dobijeni u ovom istraživanju ukazuju na nizak nivo kontaminacije mleka magarica. Ukupan broj aerobnih mezofilnih bakterija (pri 30 °C) kretao se od 0,54 do 4,77 log CFU/ml mleka. Enterobacteriaceae nisu utvrđene u 29 uzoraka pri temperaturi od 37°C, dok je u četiri uzorka bilo utvrđeno od 1,06 do 2,25 log CFU/ml mleka. Pri temperaturi od 44 °C, prisustvo Enterobacteriaceae je utvrđeno u dva uzorka u broju 1,68 i 1,15 log CFU/ml. Koagulaza pozitivne stafilokoke su bile utvrđene u dva uzorka mleka magarica i to u broju od 0,70 i 1,79 log CFU/ml mleka.

abstract = "U poslednje vreme postoji povećano interesovanje za mleko magarica, pre svega kao alternativom za majčino mleko kod dojenčadi sa alergijom na proteine kravljeg mleka, ali i s obzirom da postoji grupa potrošača koja ga konzumira zbog proklamovanih pozitivnih efekata po zdravlje. Takođe, interesovanje naučne zajednice je usmereno i na očuvanje autohtonih rasa kopitara u cilju zaštite biodiverziteta i genetičkih resursa. Higijena muže može da ima važan uticaj na kvalitet i bezbednost mleka magarice, a naročito zbog toga što se mleko magarica konzumira sirovo i da ne postoji smanjenje ili eliminacija kontaminacije primenom termičkih tretmana. U cilju procene higijenskih uslova muže magarica, u okviru ovog istraživanja su praćena tri parametra: ukupan broj aerobnih mezofilnih bakterija, broj Enterobacteriaceae (pri 37 °C i 44 °C) i broj koagulaza pozitivnih stafilokoka. Ispitivanja su izvršena primenom standardnih ISO metoda koje se koriste u mikrobiologiji hrane. Materijal su predstavljala 33 uzorka mleka magarica, prikupljena sa 6 farmi muznih magarica u Srbiji. Sve farme sa kojih su uzorci prikupljeni, su porodična gazdinstva na kojima se životinje gaje u ekstenzivnim uslovima ili poluintenzivnim uslovima. Na svim farmama se primenjuje ručna muža i prilikom pripreme životinja za mužu, vime se ne dezinfikuje, već samo pere mlakom vodom i zatim osuši papirnim ubrusom. Nakon muže, mleko se procedi kroz gazu i prelije u plastičnu ambalažu, a zatim čuva pri temperaturama hladnog lanca ili se zamrzava do prodaje i kao sirovo se konzumira. Rezultati dobijeni u ovom istraživanju ukazuju na nizak nivo kontaminacije mleka magarica. Ukupan broj aerobnih mezofilnih bakterija (pri 30 °C) kretao se od 0,54 do 4,77 log CFU/ml mleka. Enterobacteriaceae nisu utvrđene u 29 uzoraka pri temperaturi od 37°C, dok je u četiri uzorka bilo utvrđeno od 1,06 do 2,25 log CFU/ml mleka. Pri temperaturi od 44 °C, prisustvo Enterobacteriaceae je utvrđeno u dva uzorka u broju 1,68 i 1,15 log CFU/ml. Koagulaza pozitivne stafilokoke su bile utvrđene u dva uzorka mleka magarica i to u broju od 0,70 i 1,79 log CFU/ml mleka.

AB  - Насупрот планктонским бактеријским ћелијама, раст и експресија гена код бактерија у биофилму су потпуно другачије, што се нарочито одражава на њихову отпорност на средства за чишћење и дезинфекцију. 
Једном формирани биофилм, на површинама и опреми које долазе у контакт са храном, тешко се уклања и може да представља перзистентан извор контаминације хране.

(Listeria monocytogenes). Спречавање формирања и уклањање биофилма подразумева различите физичке третмане, попут примене ултразвука, магнетних и електричних поља, али и примену хемијских једињења (хлор, пероксиди, квартернерна амонијумова једињења), као и различитих ензима, бактериофага, бактериоцина и етарских уља. С обзиром да и даље не постоји универзални приступ како за спречавање формирања биофилмова, али и за уклањање већ постојећих, овај проблем и даље представља изазов и покреће нова истраживања о санитационим процедурама у индустрији хране.
AB  - Contrary to planktonic bacterial cells, the growth and genes expression of bacteria in the biofilm are completely different, which is reflected especially in their resistance to cleaning and disinfecting agents. Once formed, biofilm, on surfaces and equipment that come into contact with food, is difficult to remove and can be a persistent source of food contamination. Contamination from biofilms is an economic problem in the case of spoilage microorganisms (Pseudomonas spp., Bacillus spp.), but also a food safety issue in the case when the biofilm is formed by pathogenic bacteria (Listeria monocytogenes). Strategies to prevent the formation and removal of biofilm can be various physical sanitation treatments, such as ultrasound, magnetic and electric fields, chemical compounds (chlorine, peroxides, quaternary ammonium compounds), but also various enzymes, bacteriophages, bacteriocins and essential oils. 
Since there is still no universal method, both to prevent the formation of biofilms, but also to remove existing, this problem remains a challenge and initiates new researches with sanitation procedures in the food industry.

AB  - Enterococci represent a significant part of the non-starter LAB microbiota of artisanal cheeses produced mainly from raw milk. Common approaches to safety evaluation of enterococci isolates include assessment of antimicrobial resistance and virulence potential. Hence, a collection of 47 (n = 22, Serbia; n = 25, Slovenia) dairy enterococcal isolates, of which E. faecalis (n = 28), E. faecium (n = 11), E. durans (n = 5), E. casseliflavus (n = 2), and E. gallinarum (n = 1), was analyzed. The susceptibility to 12 antimicrobials was tested using a broth microdilution method, and the presence of the selected antimicrobial resistance and virulence genes was investigated using PCR. Isolates were resistant to tetracycline (TET) (25.5%), erythromycin (ERY) (17.0%), gentamycin and chloramphenicol (CHL) (∼6%). No resistance to ampicillin (AMP), ciprofloxacin (CIP), daptomycin (DAP), linezolid (LZD), teicoplanin (TEI), tigecycline (TGC) and vancomycin (VAN) was detected. Among all the resistance determinants analyzed, ermB gene was detected most frequently. All 10 virulence genes analyzed were detected with a distribution of cpd (72.3%), cob and ccf (70.2%), gelE (68.1%), hyl (59.6%), agg (53.2%) and esp (46.8%). The genes encoding cytolysin (cylA, cylM and cylB) were amplified to a lesser extent (21.3%, 21.3% and 12.8%, respectively). However, due to the limited number of enterococci isolates analyzed in the present study, further studies are still required in order to better document the safety status of dairy enterococci.

AB  - The aim of this study was to evaluate effects of three dairy cow groups consuming different grass diets (Diet A comprising of 20% grass, Diet B comprising of 50% grass and 100% grazed grass-G) on cow milk proximate and fatty acid (FA) com-position. The first principal component (PC1) accounted for 55.1%, and the second (PC2) accounted for 19.5% of the variance. The score values for PC1 and PC2 of the FAs show that milk fat from grass (MF G) was characterized by high C6:0, C8:0 and C14:0 con-tents. Milk from Diet A (MF A) was characterized by a higher content of C16:0. Milk from Diet B (MF B) was characterized by higher contents of C18:1n-9 and C18:2n-6 than milk from Diet A. The most favorable FA composition was in milk from Diet B, comprising 50% grass. The least favorable FA composition was in milk from Diet A, comprising 20% grass and in milk from 100% grazed grass.However, more testing is needed to bring a conclusion which food for dairy cows is the best

AB  - Spore-forming bacteria form the most diverse and most complex group of bacteria in terms of their elimination from the dairy chain, due to their ability to form highly resistant spores. As ubiquitous microorganisms, spore-formers can enter the product along the milk-processing continuum from different sources, and subsequently cause spoilage in various types of dairy products. The most important classes of spore-forming bacteria relevant to the dairy industry are Bacilli and Clostridia. Bacilli are responsible mainly for the spoilage and decreased shelf-life of fluid milk, while Clostridia cause late gas blowing in cheese. Spore-forming microorganisms contaminate raw milk primarily at the farm level, with potential for recontamination to occur at various points along the dairy production continuum. The most effective measure in reducing spore load at the farm level is adequate pre-milking teat preparation, while at the dairy plant level, bactofugation and microfiltration are applied. Understanding the ecology of spore-formers can improve application of systematic approaches for controlling the spoilage bacteria in dairy processing systems. Also, novel technologies, such as high-pressure processing, ultrasound treatment, irradiation etc., could provide the dairy industry with the powerful tools to eliminate these bacteria from the dairy chain.

AB  - The aim of this study was to evaluate the spoilage patterns of pasteurized milk microbiota. Additionally, the microbiological quality of raw and pasteurized milk regarding total aerobic and psychrotrophic counts was assessed. Samples were collected from two dairies at the milk reception point and different sites along pasteurized milk production line. Total aerobic and psychrotrophic counts in raw milk samples from Dairy 1 and 2 were at similar levels (approximately 6-7 log CFU/ml). The pasteurization step significantly reduced the total mesophilic bacteria counts. Samples from both dairies did not contain a detectable level of culturable psychrotrophic bacteria before the filling. However, psychrotrophic count in milk packages from Dairy 1 increased from 0.66±0.26 log CFU/ml to 3.76±0.19 at the end of the shelf-life. Forty-eight isolates with the different colony morphology selected from plate-count agar plates were screened for spoilage potential under laboratory conditions. The most prominent enzymatic trait (64.58% isolates) was proteolytic activity. Out of 17 enzymatically active isolates, 10 isolates were successfully identified as following: Bacillus pumilus (n=3), Bacillus licheniformis (n=2), Leifsonia aquatica (n=2), Pseudomonas oryzihabitans (n=2) and Bacillus megaterium (n=1). More stringent hygiene is required at each step of the dairy production chain to achieve a high microbiological quality of raw and pasteurized milk and to control spoilage microbiota.

AB  - Zbog malog ekonomskog značaja, magarice spadaju u tzv. "mlečne životinje od minornog značaja". Interesovanje nauke je ovde pre svega usmereno na hipoalergena, kao i potencijalno funkcionalna svojstva mleka magarice. Nizak sadržaj proteina i masti i visok sadržaj laktoze, kao i razlike u proteinskim frakcijama u odnosu na kravlje mleko, uslovljavaju specifične tehnološke karakteristike mleka magarica.

Glavna mana u senzornom kvalitetu fermentisanih proizvoda od mleka magarice je nedovoljna viskoznost, što se može poboljšati dodavanjem Na-kazeinata, pektina i treonina. Viskoznost fermentisanih proizvoda je moguće poboljšati i mešanjem sa suncokretovim uljem, kravljim ili ovčijim mlekom. Primenom tradicionalnih postupaka, od mleka magarica je mogiće dobiti samo kiselo-koagulišuće sireve, dok je proizvodnja slatko-koagulišućih sireva teško izvodljiva. Primenom specijalnih vrsta sirila, obezbeđivanjem optimalnih uslova za koagulaciju, dodavanjem mleka drugih vrsta životinja ili transglutaminaze, moguće je dobiti i slatko-koagulišuće sireve. Bez obzira na pokušaje modifikacije tehnoloških procesa, dobijeni koagulum kod slatko-koagulišućih sireva je uvek slab. Glavni problem u proizvodnji sireva od mleka magarica je visoka cena, što se može prevazići samo povećanjem produktivnosti životinja.
AB  - Due to its low economic significance, donkeys are regarded as minor dairy species. Scientific interest in donkey milk is focused on its hypoallergenic properties and potential functional characteristics. Low protein and fat content, and high lactose content in donkey milk, and different protein profile from cow milk, are responsible for its unique technological properties. Donkey milk can be preserved by high temperatures, freezing, and lyophilization. The composition is least changed by applying lyophilization. The main sensory defect in fermented products made from donkey milk is low viscosity. Viscosity can be improved by adding Na-caseinate, pectin, and threonine. Mixing donkey milk with sunflower oil, or adding cow or ewe milk can improve the final product's viscosity. Traditionally, it is only possible to produce acid-coagulated cheeses from donkey milk. By using special types of rennet, providing optimal conditions for coagulation, or adding milk from other species, it is also possible to produce enymatically cheeses. Regardless of modification of technological process, coagulum is always weak. The main limit for the mass production of donkey milk cheeses remains its high cost, which can be overcome by increasing milk yield in dairy animals.

Primenom specijalnih vrsta sirila, obezbeđivanjem optimalnih uslova za koagulaciju, dodavanjem mleka drugih vrsta životinja ili transglutaminaze, moguće je dobiti i slatko-koagulišuće sireve. Bez obzira na pokušaje modifikacije tehnoloških procesa, dobijeni koagulum kod slatko-koagulišućih sireva je uvek slab. Glavni problem u proizvodnji sireva od mleka magarica je visoka cena, što se može prevazići samo povećanjem produktivnosti životinja., Due to its low economic significance, donkeys are regarded as minor dairy species. Scientific interest in donkey milk is focused on its hypoallergenic properties and potential functional characteristics. Low protein and fat content, and high lactose content in donkey milk, and different protein profile from cow milk, are responsible for its unique technological properties. Donkey milk can be preserved by high temperatures, freezing, and lyophilization. The composition is least changed by applying lyophilization. The main sensory defect in fermented products made from donkey milk is low viscosity. Viscosity can be improved by adding Na-caseinate, pectin, and threonine. Mixing donkey milk with sunflower oil, or adding cow or ewe milk can improve the final product's viscosity. Traditionally, it is only possible to produce acid-coagulated cheeses from donkey milk. By using special types of rennet, providing optimal conditions for coagulation, or adding milk from other species, it is also possible to produce enymatically cheeses. Regardless of modification of technological process, coagulum is always weak. The main limit for the mass production of donkey milk cheeses remains its high cost, which can be overcome by increasing milk yield in dairy animals.",

AB  - Leuconostoc spp. are widely distributed in dairy environments, mostly as adjunct cultures and non-starter lactic acid bacteria. In order to gain Qualified Presumption of Safety status, bacteria must not carry transferable resistance to antibiotics. Although members of lactic acid bacteria are recognized as safe, constant monitoring of antibiotic resistance is recommended by European Food Safety Authority. The aim of this study was to evaluate antibiotic resistance in Leuconostoc isolates of cheese origin.
This study was conducted on 20 Leuconostoc isolates belonging to two species: Leuconostoc mesenteroides (n=18) and Leuconostoc pseudomesenteroides (n=2). All investigated isolates originated from Serbian traditional raw milk cheeses – Zlatar, Sjenica and Homolje cheese. Minimum inhibitory concentrations were determined by broth microdilution method for 8 antibiotics and results were interpreted according to European Food Safety Authority guidance. Most prevalent resistance phenotype was resistance to kanamycin (n=15), following with resistance to chloramphenicol (n=6), and streptomycin (n=5). One Ln. mesenteroides isolate showed multiresistance, with resistance to 7 out of 8 investigated antibiotics. Genetic basis of tetracycline resistance (tet(A), tet(B), tet(C), tet(K), tet(L), tet(M), tet(O) and tet(W) genes) was analyzed by PCR method in all isolates. None of the analyzed genes was found in any of the isolates. According to the results of this study Leuconostoc isolates are not a reservoir of tetracycline resistance. However, determining genetic basis of antibiotic resistance is necessary for the complete risk assessment regarding transferable antibiotic resistance in the isolates.
