In vitro effect of phospholipase C from Bacillus cereus on tissue thromboplastin from different species.
Purified phospholipase C from Bacillus cereus caused a significant loss in the procoagulant activity of thromboplastin preparations from man, rabbit, sheep, cow, rat and mouse. However, marked differences were observed with respect to the degree of inactivation. Rat, mouse, bovine and one type of rabbit preparations (prepared from acetone powdered brain) were markedly more sensitive to attack by phospholipase C than were preparations of human, sheep and standard rabbit preparations. The relative amounts of the individual phospholipids in thromboplastin preparations showed only minor variations among the species. The effect of phospholipase C on each of these phospholipids in the various thromboplastin preparations showed some significant differences.
