Effect of some antibiotics and disinfectants on enteric bacteria isolated from some food

ABSTRACT

Antibacterial effect of erythromycin, streptomycin, kanamycin, ampicillin, chloramphenicol, tetracycline, amoxycillin and gentamicin as well as iodophor and savlon on bacteria isolated from milk, Kareish cheese, Domiatti cheese and meat products was investigated by using both disc and well methods. The majority of tested microorganisms in this study showed a high susceptibility to streptomycin, kanamycin, chloramphenicol, tetracycline and gentamicin, while, resistant to erythromycin, ampicillin and amoxycillin. Salmonella muenster was susceptible to all antibiotics used, but Salmonella typhimurium and Sal. newport were resistant to erythromycin and ampicillin. The results revealed that most tested microorganisms were sensitive to iodophor then savlon. The possible implication to animal and human heath were discussed
