In vivo muscle damage during Candida infection

Abstract

The concentration of the muscle enzyme creatine phosphokinase increased in the sera of mice during acute, systemic infection with Candida albicans. Elevated serum enzyme levels were first detected 6h after challenge with C. albicans and continued to rise during the next 6 h as animals became moribund. A linear relationship was demonstrated between the serum creatine phosphokinase concentration and the dose of C. albicans injected. In vivo muscle damage was produced by virulent isolates of C. albicans, C. stellatoidea, and C. tropicalis. Tissue injury was mediated through the elaboration of a factor by metabolically-active C. albicans and was restricted to those sites in which high concentrations of organisms were present.

Zusammenfassung

Die Konzentration des Muskelenzymes Kreatine-phosphokinase nimmt im Serum von Mäusen, die akute, disseminierte Candida-Infektion haben, zu. Erhöhte Werte können zum ersten Mal 6 Stunden nach der Injektion festgestellt werden und nehmen in den nächsten 6 Stunden zu. Zu diesem Zeitpunkt werden die Tiere moribund. Es konnte ein lineares Verhältnis zwischen der Konzentration des Enzymes und der Zahl der injizierten Hefezellen von Candida albicans demonstriert werden. Virulente Stämme von Candida albicans, C. stellatoidea und C. tropicalis erzeugten Muskelzerstörung in vivo. Der Gewebsschaden hängt von der Bildung eines Faktors ab, der von metabolisch-aktiven Candida-Stämmen produziert wird und ist beschränkt auf die Stellen, wo hohe Konzentrationen des Erregers gefunden werden.
