R factors determining multiple resistance including both gentamicin and carbenicillin have been identified in high incidence among hospital isolates of Pseudomonas aeruginosa. The factors are readily transmitted to other P. aeruginosa but not to Escherichia coli strains K-12 or C, or to Proteus mirabilis. R factor-containing isolates are predominantly immunotype 7 isolated from urinary sources.
在铜绿假单胞菌的医院分离株中,已发现决定对庆大霉素和羧苄青霉素多重耐药的R因子具有高发生率。这些因子很容易传播给其他铜绿假单胞菌,但不会传播给大肠杆菌K - 12或C菌株,也不会传播给奇异变形杆菌。含有R因子的分离株主要是从尿液来源分离出的免疫型7。
