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 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 کاملObligate anaerobes which form skatole.
Although the presence of skatole in decomposing protein materials and in feces has frequently been reported, very rarely have microorganisms been shown to form skatole in pure culture. Two species of the genus Clostridium have been described as producing skatole: Clostridium skatol Fellers and Clough (J. Bacteriol., 10, 130, 1925), which had been characterized earlier by Fellers (Abstr. Bacteri...
متن کاملImproved culture flask for obligate anaerobes.
An improved flask system for the growth of extremely oxygen-sensitive bacteria in liquid culture is described. The improvement described utilizes an all-glass, neoprene-stoppered flask designed for growth of 50- to 1,000-ml cultures of bacteria with continuous gassing.
متن کاملPipette count method for obligate anaerobes.
The routine counting of obligate anaerobic bacteria is a serious problem in many laboratories. Reliable anaerobic chambers are either expensive or messy and cumbersome. Furthermore, the exposure of certain genera, notably Bacteroides and some spirochetes, to air may kill the organisms. The following technique does not require an anaerobic chamber, does not expose the organism to atmospheric oxy...
