R factor compatibility groups

Molecular and General Genetics MGG, 1972
Eight R factors are described which fall into four compatibility groups, distinct from previously described F-like and I-like groups. E. coli K12 carrying one of these factors, TP114, supports multiplication of the I-specific phage If1. However, TP114 is fully compatible with the I-like factor T-Δ and with all the other R factors described in this ...

R Factor Transmission In Vivo

Journal of Bacteriology, 1969
Experimental infections were induced in weanling pigs orally both with nalidixic acid (NA)-sensitive and -resistant strains of Salmonella choleraesuis var. kunzendorf , designated RC221 and RC221NA, respectively. Prior to the time of infection, cultures of normal bacterial flora were isolated

The Ecology of R Factors

New England Journal of Medicine, 1970
THE ability of many gram-negative bacilli to resist certain commonly used antibiotics has been shown to be mediated in large part by R factors.

R Factors for Aminoglycoside Antibiotics

Journal of Infectious Diseases, 1969
The definition of R factors by Japanese scientists 10 years ago opened a new chapter in the saga of antibiotic resistance among enteric bacteria [1]. This package of extrachromosomal genes, comprised of the resistance determinants, which mediate resistance to a variety of environmental hazards, and the resistance transfer factors (RTF), which mediate ...
