[Study of the pathogenicity and drug sensitivity of staphylococci isolated from poultry].

Studied were the pathogenicity and drug sensitivity of a total of 64 Staphylococcus strains isolated from chickens and chick embryos. A high per cent value of coincidence was established between the tests of positive plasma-coagulase reaction, hemolysis, golden-yellow pigment production, glucose-positive reaction in anaerobiosis and the lethal sequela following the experimental infection of young chickens and albino mice. The complex use of these tests proved to be a dependable criterion of pathogenicity. Most of the Staphylococcus strains were shown to be strongly and moderately sensitive to kanamycin gallimycin, oximycin, chloramphenicol, and persistent to oxitetracyclin.
