INCIDENCE AND ANTIBIOTIC RESISTANCE OF PLASMID BORNE AVIAN PATHOGENS FROM POULTRYK. NTITIYA AND A. MOHANKUMARAbstract The presence of some human entero -pathogens in poultry is responsible for much of the food - borne out breaks of illness worldwide. The in vitro antibacterial activity of 10 antimicrobials against 75 Escherichia coli, 15 Salmonella spp., and 75 Streptococcus spp., were studied. Fourteen antibiotypes were identified in Escherichia coli, two antibio types were identified in Salmonella spp., and twenty two an tibiotypes were identified in Streptococcus spp.,. The multiple antibiotic resistant (MAR) index of the isolates were higher than 0.2 suggesting their origin from a high risk source of contamination where antibiotics often used. These organisms could have been transmitted horizontally between them and prevailed in the reservoirs for prolonged periods. One step and multi step antibiotic resistant mutants were isolated. The organisms were plasmid borne with, 7421 bp molecular weight.
