MIC's for selected antimicrobials against Escherichia coli. Recovered from various animal species in Zimbabwe compared with isolates from Australia and the United States

Abstract

The MIC medians of ampicillin, cefalotin, gentamicin,kanamycin, oxytetracycline, penicillin G, spectinomycin, sulphachlorpyridazine, sulphadimethoxine and trimethoprim-sulphamethoxazole combination were compared between locations using 2 non parametric tests, the Median and Kruskal-Wallis test. Typically, isolates from Zimbabwe were more sensitive to several of the antimicrobials than were isolates from Australia and the USA. There were few distinct or consistent differences between isolates from Australia and the USA.
