Popis: Phospholipase C (lecithinase or phosphatidylcholine Phosphorylase) catalyzes the hydrolysis of lecithin into phosphorylcholine and 1,2-diglyceride. Bacterial production of phospholipase C may damage reproductive tract tissues by both direct and indirect mechanisms. Use of the synthetic substrate p-nitrophenylphosphorylcholine polspholipase C activity was determined in 204 isolates representative of those found in female genital tract. Multiple aerobic (28%) and anaerobic (28%) reproductive tract microorganisms showed phospholipase C activity. Phospholipase C-producing isolates included strains of Bacteroides fragilis, B. bivius, B. thetaiotaomicron, Gardnerella vaginalis , and group B streptococcus. Phospholipase C activity was heterogenous; not all isolates that belong to a particular species showed activity. Phospholipase C production may be a possible virulence factor produced by a number of microflora commonly implicated in various reproductive tract infections or conditions, as well as in some instances of preterm birth.
