Abstract
This study investigated the incidence of multi-drug resistant (MDR) organisms in poultry and poultry products in Egypt. from a total of 300 poultry and poultry product samples 25, 20, 15, and 10 isolates were recognized as Salmonella spp., E.coli, S.aureus and E.faecalis by bacteriological and molecular methods. Studying antibiotic sensitivity pattern of the bacterial isolates , multidrug resistance to three or more classes of antimicrobial groups was observed in 9 (36%), 18(90%), 15(100%), and 9 (90%) isolates of Salmonella spp., E.coli, S. aureus and E. faecalis, respectively. E. coli and Salmonella isolates were tested for its susceptibility against 14 different antibiotics; the highest resistance rates in E. coli were recorded against tetracycline, chloramphenicol , ampicillin, and sulphamethoxazole-trimethoprim with resistance rates of 90% , 85% ,80% and 80 % ,respectively.The highest sensitivity rates were detected for amikacin , cefuroxime and ampicillin-sulbactam with sensitivity rates 100%, 75% and 70% , respectively. In Salmonella isolates increased resistance to cefotaxime and tetracycline with a percentage of 80% and 64% was detected, respectively. Also the highest sensitivity rates were detected for amikacin and ampicillin-sulbactam with sensitivity rates of (92%), and (88%) for amoxicillin clavulanate and ceftazidime. The antibiotic susceptibility pattern of S.aureus was studied against 12 different antibiotics. The highest resistance rates were detected against methicillin, pencillin, erythromycin and azithromycin with resistance rates of (100%) and (80%) for gentamycin . The highest sensitivity rate was detected towards vancomycin with a percentage of 80%. In enterococci (100%) of the strains were resistant to clindamycin and ampicillin, (80%) for rifampin and 70% for tetracycline. The highest sensitivity rates were detected to pencillin and vancomycin with a percentage of 80%and 60%,respectively
