Abstract
Activation of blood coagulation to a varying extent affect the course of domestic invasive mycoses. Upon invasion of blood vessels by Candida or aspergilli, occasionally thrombi are formed, which may cause septic embolism. In the course of mucormycosis (syn. zygomycosis) thrombotic occlusion of afflicted blood vessels and subsequent necrosis of dependent tissue regularly occurs. Coagulation during candidosis or aspergillosis may be triggered by secreted aspartic proteinases which are able to activate factor X as has been shown previously [1, 2]. During mucormycosis, severe blood coagulation apparently is due to paracoagulation of fibrinogen which is triggered by low concentrations of extracellular fungal subtilisin-like proteinase (Arp). The enzyme is also able to inactivate the major inhibitor 4 blood coagulation (antithrombin III). Recent findings on the action of Arp are discussed.
