Abstract

Summary

Endocarditis is a rather frequent complication of Q fever caused by We examined the ability of phase I (virulent) or phase II (avirulent) to coagulate blood in the presence of human blood mononuclear cells After incubation for 4 h, virulent phase I was an effective stimulant for mononuclear cells. Since this interaction is a potent trigger of blood coagulation through the extrinsic pathway, it could be responsible for the local deposition of fibrin on the surface of infected valves and the development of large vegetations in cases of endocarditis complicating Q fever.
