“…The arterial blood collected included 0.5 mL of nonanticoagulated blood for glucose measurement [33] and 0.5 mL of whole blood for bacterial colony counts [34]. Not more than 10% of the estimated total blood volume (70 mL/kg) was withdrawn over the first 24 h.…”

Group A streptococcal infections, ranging from necrotizing fasciitis and myositis to toxic shock syndrome, have increased over the last 10 years. We developed the first primate model of necrotizing fasciitis and myositis. Thirteen baboons were inoculated intramuscularly with group A streptococci (GAS). Eleven animals survived for > or = 11 days before sacrifice, and two animals died within 2 days. The site of inoculation of the survivors exhibited an intense neutrophilic influx (stage I), followed by a lymphoplasmacytic influx (stages II and III). This was accompanied by the appearance of markers of an acute and then a chronic systemic inflammatory response. In contrast, the site of inoculation of the two nonsurvivors exhibited intravascular aggregates of neutrophils at its margin with no influx of neutrophils and with extensive bacterial colonization. We conclude that GAS inoculation induces a local and systemic acute neutrophilia followed by a chronic lymphoplasmacytic response; failure, initially, of neutrophilic influx into the site of inoculation predisposes to systemic GAS sepsis and death; and this three-stage primate model approximates the human disease.

“…In many studies baboons (Papio cyanocephalus cynocephalus) have been used to investigate the efficacy of potential therapeutic substances by assessing their ability to improve the survival of a lethal Escherichia coli infusion [2,3]. In such animal models, the effect of the therapeutic intervention on the coagulopathy induced by septicaemia can be defined using welldefined end points, such as the amount of fibrinogen consumption and fibrin deposition [7,8]. However, these models are not sufficiently specific to analyse incisively the involvement of individual coagulation and fibrinolytic factors or inhibitors in the pathogenesis of DIC.…”

Abstract. Disseminated intravascular coagulation (DIC)is a frequently occurring complication of sepsis and may contribute to multiple organ failure. More insight into the pathogenesis of this derangement of the coagulation system is necessary to develop more effective therapeutic strategies for this condition. Recently, more detailed knowledge on the pathogenetic pathways involved in DIC has been obtained by the study of models of experimental bacteraemia and endotoxaemia in human subjects and non-human primates. The mechanisms that lead to activation of coagulation, potentiated by the simultaneous depression of physiological inhibitory systems and to impaired function of the fibrinolytic system, are outlined in this review. In addition, the mediatory role of various cytokines in the derangement of coagulation is discussed.
