Phagocytosis and killing of Gardnerella vaginalis by human neutrophils.
Gardnerella vaginalis was ingested and killed by neutrophils in the presence of normal human serum. Heat inactivation of the serum inhibited these processes. The opsonisation of some but not all G vaginalis strains was enhanced by immune rabbit serum. Immune serum did not, however, enhance intracellular killing. Blockade of the classical pathway of complement activation had no effect on the ops...
متن کاملPhagocytosis and killing of Staphylococcus aureus by human neutrophils.
Neutrophils are essential for host defense against Staphylococcus aureus infections. Although significant progress has been made, our understanding of neutrophil interactions with S. aureus remains incomplete. To provide a more comprehensive view of this process, we investigated phagocytosis and killing of S. aureus by human neutrophils using varied assay conditions in vitro. A greater percenta...
متن کاملPhagocytosis and killing of epidemic methicillin-resistant Staphylococcus aureus by human neutrophils and monocytes.
Staphylococcus aureus is a pathogen that has been associated with nosocomial infections since the preantibiotic era. Since the introduction of antibiotics in medical practice in the 1940 s, methicillin-resistant S. aureus (MRSA) strains have been emerging in various parts of the world. In view of the important role of the phagocytic system in the defense against this bacteria, we decided to stu...
متن کاملBiotypes of Gardnerella vaginalis.
A simple and reproducible scheme for identifying biotypes of Gardnerella vaginalis has been developed, based on reactions for lipase, hippurate hydrolysis, and beta-galactosidase. Among a total of 359 strains tested, eight biotypes were observed, the most common ones being types 1 (beta-galactosidase positive, lipase positive, hippurate positive), 2 (beta-galactosidase negative, lipase positive...
متن کاملAcquisition of iron by Gardnerella vaginalis.
Six Gardnerella vaginalis strains were examined for the ability to utilize various iron-containing compounds as iron sources. In a plate bioassay, all six strains acquired iron from ferrous chloride, ferric chloride, ferrous sulfate, ferric ammonium citrate, ferrous ammonium sulfate, bovine and equine hemin, bovine catalase, and equine, bovine, rabbit, and human hemoglobin. All six strains also...
