Recombination-deficient Streptococcus sanguis.
A UV-sensitive derivative was obtained from Streptococcus sanguis Challis. The organism could be transformed with a number of small streptococcal plasmids at frequencies equal to, or 1 logarithm below, the transformation frequencies for the parent organism. However, transformation with chromosomal DNA was greatly impaired in the UV-sensitive derivative.
متن کاملCloning and characterization of the tetracycline resistance determinant of and several promoters from within the conjugative transposon Tn919.
Tn919 is a 15- to 16-kilobase (kb) tetracycline resistance conjugative transposon that was originally isolated from Streptococcus sanguis FC1. The tetracycline resistance determinant (tet) was found on a 4.2-kb HindII fragment by in vitro deletion analysis. This fragment was subcloned to a pWV01 origin capable of directing replication in Escherichia coli, Bacillus subtilis, and Streptococcus la...
متن کاملProphylactic Immunization against Streptococcus sanguis.
Streptococcus sanguis (the Streptococcus s.b.e. of Loewe), originally identified by White and his coworkers, has, with few exceptions, been isolated only from the blood stream of patients with subacute bacterial endocarditis (White, 1944; White and Niven, 1946; Niven and White, 1946; Loewe et al., 1946; Niven et al., 1946; Washburn et al., 1946). This causative organism has a type specificity a...
متن کاملLipoteichoic acids from Streptococcus sanguis.
Two lipoteichoic acids, membrane (MLTA) and wall (WLTA), have been purified from Streptococcus sanguis by Sepharose and Ecteola-cellulose column chromatographies and concanavalin A-conjugated Sepharose affinity column chromatography. The teichoic acids were homogenous as judged by disc gel electrophoresis, column chromatography, and double diffusion tests. Both MLTA and WLTA consisted of glycer...
