Nonopsonic phagocytosis of group C Neisseria meningitidis by human neutrophils.
Although complement-mediated bactericidal activity in serum has long been known to be very important in host defense against Neisseria meningitidis, recent studies have shown that opsonic phagocytosis by neutrophils is also important. The purpose of this study was to determine if endemic group C N. meningitidis strains were susceptible to nonopsonic (complement- and antibody-independent) phagoc...

متن کاملSerotype Distribution and Invasive Potential of Group B Streptococcus Isolates Causing Disease in Infants and Colonizing Maternal-Newborn Dyads
BACKGROUND Serotype-specific polysaccharide based group B streptococcus (GBS) vaccines are being developed. An understanding of the serotype epidemiology associated with maternal colonization and invasive disease in infants is necessary to determine the potential coverage of serotype-specific GBS vaccines. METHODS Colonizing GBS isolates were identified by vaginal swabbing of mothers during a...
متن کاملEndocarditis caused by nonhemolytic group B streptococcus.
We report a case of bacterial endocarditis caused by nonhemolytic group B streptococcus (GBS) in a 67-year-old man with no predisposing risk factors. Nonhemolytic GBS strains rarely cause illness and are usually detected in perinatal infections. We believe this to be the first reported case of endocarditis caused by a nonhemolytic strain of GBS.
متن کاملPhagocytosis of brushite crystals by pig neutrophils.
Neutrophils from pig blood were disrupted by homogenisation or sonication and placed on an analytical sucrose gradient. Pig neutrophil azurophil granules were less dense than the specific granules, unlike those from neutrophils of most other mammalian species. Brushite crystals, which stimulate the respiratory burst in pig neutrophils, were found by electron microscopy to be phagocytosed. Membr...
