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 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...
متن کاملInteractions between oral bacteria: inhibition of Streptococcus mutans bacteriocin production by Streptococcus gordonii.
Streptococcus mutans has been recognized as an important etiological agent in human dental caries. Some strains of S. mutans also produce bacteriocins. In this study, we sought to demonstrate that bacteriocin production by S. mutans strains GS5 and BM71 was mediated by quorum sensing, which is dependent on a competence-stimulating peptide (CSP) signaling system encoded by the com genes. We also...
