The latter were ampicillin, chloramphenicol, erythromycin, gentamycin, nalidixic acid, neomycin, streptomycin, sulfamethoxazole/trimethoprim and tetracycline. A considerable variation in their pattern of sensitivity was shown. Almost all isolates showed sensitivity to chloramphnicol. On the other hand, the strains were all insensitive to erythromycin. Forty-one patterns of drug susceptibility reactions were obtained. Each pattern was represented by a single strain with the exception of three of them which included two strains each.On the whole, 26 patterns of drugs resistance that ranged between resistance to a single drug and seven drugs were encountered A scheme of drug susceptibility patterns is put forward for use in routine clinical diagnosis as well as epidemiological investigations.} }
