Abstract

Escherichia coli, Salmonella pullorum and Salmonella gallinarum were tested for susceptibility to Chloramphenicol by tube broth dilution technique and disk-diffusion method. MICS and Zone diameter were correlated with production of chloramphenicol acetyltransferase (CAT). Also Evaluation of a 30-minutes commercial disk procedure demonstrated that, it is as accurate as 1-hour tube method for detection of resistance among these strains.
