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 کاملConjugal fertility associated with resistance factor R in Escherichia coli.
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...
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...
متن کاملAGE proteins as a causative factor in Alzheimer's Disease
The reaction between reducing sugars and protein free amines, known as the Maillar reaction results in the formation of advanced glycation endproducts (AGEs). AGE modification changes the structure of proteins to amyloid cross-beta structure. These protein structures can activate receptors known as RAGE on glial cells (microglia and astrocytes), and induce the expression of inducible nitric oxi...
متن کاملPenicillin-binding proteins of Escherichia coli. Comparison of a strain carrying an R-factor and the parent strain.
Both from Escherichia coli K12 W3630 carrying an R-factor, R+75, and from the parent strain at least six penicillin- and cephalosporin-binding proteins were obtained as soluble forms. The molecular weights of the binding proteins of the strain carrying an R-factor were similar to those of the parent strain and not affected by the presence of an R-factor which specified the production of a beta-...
