Opis (eng)

Wastewater originating from the meat processing industry is characterized by the high presence of organic waste load as well as potentialy pathogenic microorganisms. This study consisted of four sampling campaigns, during four seasons in 2013 and 2014. Wastewater was collected from three meat processing plants in the Province of Vojvodina, Republic of Serbia. The aim of this research was to determine the posible resistance of isolated E. coli strains to selected antibiotics.The evaluation of the antimicrobial susceptibility was performed on 37 strains of E. coli to 9 different antibiotics. Antibiotics, as emerging pharmaceuticals, used for susceptibility testing were: ampicillin, cefotaxime, ciprofloxacin, chloramphenicol, gentamicin, nalidixic acid, streptomycin, tetracycline, and trimethoprim-sulfamethoxazole. Monitoring of antimicrobial resistance in commensal bacteria E. coli is of great significance because this bio - species is commonly present in animal faeces, in human organism, and can often acquire conjugative plasmids from other present enteric bacteria, thus serving as a valuable reservoir of resistance genes which can be transferred to other bacteria present in same environment. From a total of 37 strains of E. coli, a moderate degree of resistance was shown to tetracycline (37.83%); low degree of resistance to ampicillin (21.62%), streptomycin (24.32%), trimethoprim-sulfamethoxazol (18.92%) and nalidixic acid (16.22%); a very low to: chloramphenicol (13.51%), ciprofloxacin (2.7%), gentamicin and cefotaxime (0.0%). Ten of the tested E. coli strains (18.92%) were multidrug-resistant (MDR). Antibiotics used in this experiment are present on the NORMAN list of emerging substances of concern, since they are most frequently detected in aquatic environment. Due to their detectable presence in the environment, we have to be very careful because it increases the possibility for antimicrobial ressistance in microorganisms which have been in contact with antibiotic residues. High public pressure considering the consequences of mass appearance of multi-resistant bacterial strains that have spread from the animals to humans, managed to significantly reduce the use of antibiotics, especially as growth promoters.Serbia also adopted this EU legislation but more stringent control of law implementation is needed.
