In vitro antimicrobial sensitivity of isolates of Yersinia pseudotuberculosis from deer

The in vitro sensitivity of 34 isolates of Yersinia pseudotuberculosis from red deer (Cervus elaphus) was determined by disc diffusion tests using 15 antimicrobial drugs. All isolates were sensitive to ampicillin, chloramphenicol, gentamycin, kanamycin, neomycin, “septrin” (combination of trimethoprim and sulphamethoxazole) streptomycin and tetracycline. Twenty isolates were sensitive to polymyxin B and 14 were resistant. All isolates were resistant to bacitracin, erythromycin, novobiocin and moderately resistant to furazolidone. The responses using sulphafurazole or trimethoprim were difficult to interpret accurately but most isolates were classified as sensitive.
