Anaerobic R factor transfer in Escherichia coli.
R factor mediated transfer of antibiotic resistance between Enterobacteriaceae has been reported to occur in the mammalian gastrointestinal tract (Kasuya, I 964; Reed, Sieckmann & Georgi, 1969; Guinie, 1970; Wiedemann, Knothe & Doll, 1970) where conditions are mainly anaerobic as demonstrated by the abundance of obligate anaerobic bacteria such as Bacteroides species (Moore, Cat0 & Holdeman, 19...
متن کاملIsolation and characterization of lividomycin A inactivated by Pseudomonas aeruginosa and Escherichia coli carrying R factor.
served in IR spectrum. The inactivated lividomycin A consumed 6.2 moles of periodate for 24 hours as does lividomycin A (5.9 moles). Methanolysis of the inactivated lividomycin A (refluxed in 0.4 N hydrogen chloride in methanol for 6 hours) gave 3'deoxyparomamine, methyl lividotriosaminide phosphate and a small amount of methyl lividobiosaminide phosphate. These results indicate that the inacti...
متن کاملElevated Risk of Carrying Gentamicin-Resistant Escherichia coli among U.S. Poultry Workers
BACKGROUND Antimicrobial use in food-animal production is an issue of growing concern. The application of antimicrobials for therapy, prophylaxis, and growth promotion in broiler chicken production has been associated with the emergence and dissemination of antimicrobial-resistant enteric bacteria. Although human exposure to antimicrobial-resistant bacteria through food has been examined extens...

remain ill-defined. The first R factor described, and most of those studied subsequently in Japan (T. Watanabe, Bacteriol. Rev. 27:87, 1963), mediated resistance to sulfonamides (SU), streptomycin (SM), tetracycline (TC), and chloramphenicol (CM). These results, and the lack of evidence that this pattern of resistance had gradually accumulated in Japan, suggested that this was the parent R fact...

Sugino, Yoshinobu (Osaka University, Osaka, Japan) and Yukinori Hirota. Conjugal fertility associated with resistance factor R in Escherichia coli. J. Bacteriol. 84:902-910. 1962.-The introduction of the contagious drug-resistance factor, R, into an F(-) strain of Escherichia coli allows the R(+)F(-) strain to mate with F(-)R(-) strains. The chromosome fragment transferred from the R(+) cell is...
