Pathophysiologic features of Q fever-infected guinea pigs.
Guinea pigs infected with 9-mile phase I strain of Coxiella burnetii had increased blood glucose concentrations; alkaline phosphatase (ALP), glutamic-oxalacetic transaminase (GOT), alpha-hydroxybutyrate dehydrogenase (alpha-HBDH), and creatine phosphokinase (CPK) activities; and bilirubin value. Hypocalcemia and hypophosphatemia were evident in the latter days of infection. At necropsy of the guinea pigs, necrotic foci were in liver, spleen, and heart. Seemingly, the major pathophysiologic changes in infected guinea pigs were the direct result of lesions in liver, spleen, and heart in which rickettsial bodies were readily observable with histologic staining procedures. The guinea pig may serve as an animal disease model for Q fever.
