Immunochemical Analysis of Streptococcus bovis, Strain s19, Cell Walls

Glycans from streptococcal cell walls: structural features of a diheteroglycan isolated from the cell wall of Streptococcus bovis.

Streptococcus bovis meningitis.

Nisin resistance of Streptococcus bovis.

The growth of Streptococcus bovis JB1 was initially inhibited by nisin (1 microM), and nisin caused a more than 3-log decrease in viability. However, some of the cells survived, and these nisin-resistant cells grew as rapidly as untreated ones. To see if the nisin resistance was merely a selection, nisin-sensitive cells were obtained from agar plates lacking nisin. Results indicated that virtua...

A Transglucosylase of Streptococcus Bovis.

1. A transglucosylase has been separated from the alpha-amylase of Streptococcus bovis by chromatography of the cell extract on DEAE-cellulose. 2. The transglucosylase can synthesize higher maltodextrins from maltotriose, but maltose, isomaltose and panose do not function as donors. 3. Iodine-staining polysaccharide may be synthesized from maltotriose provided that glucose is removed. Synthesis...

Streptococcus bovis endocarditis: analysis of cases between 2005 and 2014.

BACKGROUND Streptococcus bovis is a classical etiology of endocarditis and is associated with colonic lesions. No series of cases from Brazil has been described. OBJECTIVES To describe aspects of S. bovis endocarditis. METHODS This is a case series of patients admitted to a cardiac surgery referral center, during the years 2005-2014. Clinical, laboratory, echochardiographic, colonoscopic, t...
