[Antibiotic sensitivity of hospital strains of Staphylococcus].

Seven hundred and six clinical strains of Staphylococcus spp. isolated in different cities of the former USSR in 1986-1992 were investigated. It was shown that the isolates had multiple drug resistance. The hospital strains of Staphylococcus aureus more frequently contained the plasmids with the molecular weight of 21.0 and 18.0 MD as well as the plasmids with the molecular weight of 1.4 MD determining erythromycin resistance. The plasmids with the molecular weight of 3.0 and 2.6 MD were detected which determined streptomycin and tetracycline resistance respectively. Lincomycin and carbenicillin resistance was determined by the chromosomal genes. The elimination studies demonstrated that gentamicin resistance could be determined by the extrachromosomal genes.
