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 کاملAmplification of sex repressor function of one fi-+ R-factor during anaerobic growth of Escherichia coli.
It has been reported by Mitsuhashi (1965) that transfer of one R-factor was completely inhibited by anaerobic transfer conditions. In contrast, several workers have observed R-factor transfer, although at a reduced rate, in the animal intestines, a largely anaerobic environment. It is shown here that in vitro transfer of the R-factor R1 (F-type pilus, fi-+) in Escherichia coli K-12 is severely ...
متن کاملR-Factor in Salmonella enterica serovar typhi: transfer to and acquisition from Escherichia coli.
Blood culture isolates of Salmonella enterica serovar Typhi showing high degrees of resistance to ampicillin, chloramphenicol, cotrimoxazole and tetracycline (ACCoT-resistance) transferred their full resistance phenotype to antibiotic-sensitive S. enterica serovar Typhi strains through the primary recipient Escherichia coli C600. Transfer frequencies were 0.80 x 10(-5) and 0.80 x 10(-6), respec...
متن کاملR factor infection of Escherichia coli lyophilized in 1946.
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...
