Properties of an R factor from Pseudomonas aeruginosa.

An R factor from Pseudomonas aeruginosa, which confers resistance to penicillins, kanamycin, and tetracycline, was studied in Escherichia coli K-12. The R factor could coexist with F-like or I-like plasmids and therefore constituted a novel compatibility group. The R factor was transferable from E. coli to bacterial genera outside the Enterobacteriaceae (Pseudomonas and members of the Rhizobiaceae) to which transfer of F-like and I-like plasmids could not be demonstrated.

Drug resistance and R factors in the bowel bacteria of London patients before and after admission to hospital.

The content of drug-resistant coliform bacteria in faecal specimens collected before admission from patients awaiting non-urgent surgery were compared with specimens collected in hospital. Resistant strains of Escherichia coli were isolated from 52% of preadmission specimens and were present in large numbers in 28%. Tetracycline, sulphonamide, and streptomycin resistance were commonest: 60% of resistant strains carried transmissible R factors and multiple resistance was commoner than single. No characteristically resistant intestinal bacteria of any genera were found in hospital specimens as compared with those from outside.
