Susceptibility of Pseudomonas pseudomallei isolates of non-human origin to chemotherapeutic agents by the single disc sensitivity method

Single disc sensitivity tests against 42 strains of Pseudomonas pseudomallei isolated from soil, water, sheep, pigs, goats, birds, a horse and a tree kangaroo have shown that a remarkably similar pattern occurs to that obtained in isolates from human cases. Generally, the organisms are sensitive to kanamycin, novobiocin, compound sulphonamides, sulphamethoxazole/trimethoprim and tetracycline and resistant to ampicillin, bacitracin, cloxacillin, colistin, erythromycin, gentamycin, nitrofurantoin, penicillin, polymyxin B, streptomycin and vancomycin. Sensitivity to neomycin was variable.
