Antibioresistance of Escherichia coli isolated from freshly slaughtered poultry

Fifty strains of Escherichia coli from both fecal and total coliforms, aIl originated from freshly slaughtered poultry in traditional shops were studied for their antimicrobial sensitivity. Seven antibacterial agents, widely used in human medicine, were tested: Amoxicillin (AMX), Streptomycin (S), Spectinomycin (SPT) Sulfonamides (SSS), Gentamicin (GM), Flumequin (UB) and Colistin (CS). A significant percentage of isolates (76%) were resistant to at least 1 antimicrobial agent. Antibiograms showed high levels of resistance to S, SSS 'and SPT. Medium to low frequencies ofresistance were noted to the remainder. The most frequent antibiotypes are: SSS, SPT/S, S/SSS, SPT/S/SSS et SPT/S/SSS/CS.
