[The isolation and characteristics of the biological and genetic properties of neamin-resistant mutants of Salmonella abortus-ovis that are promising for vaccine creation].

Abstract excerpt

Neamine-resistant mutants were obtained from S. abortus ovis virulent strain. These mutants were divided into three classes according to their sensitivity to streptomycin: mutants completely retaining their sensitivity, mutants sensitive to moderate and high doses of the antibiotic. On the basis of genetic analysis carried out with the use of bacteriophage P22, the Near mutation of class Near 100 Strr 500 mutants...
