SOME BIOCHEMICAL CHANGES IN THE GUINEA PIG DURING INFECTION WITH COXIELLA BURNETII.
Paretsky, D. (University of Kansas, Lawrence), C. M. Downs, and C. W. Salmon. Some biochemical changes in the guinea pig during infection with Coxiella burnetii. J. Bacteriol. 88:137-142. 1964.-Guinea pigs infected with Coxiella burnetii, the rickettsial agent of Q fever, were studied for 11 days postinfection. Maximal changes in liver lipids, liver phosphorylase, and uridine diphosphate glucose (UDPG)-glycogen glucosyl-transferase activities occurred 3 to 4 days post-infection. In this period, total liver lipids increased from 1.26 to 5.46 mg/mg of N, with the largest increment in the glyceride fraction. Liver glycogen virtually disappeared by the second day, with no chemically detectable restoration until the eleventh day. A pattern of altered phosphorylase and UDPG-glycogen transglucosylase activities was observed, with maximal phosphorylase and minimal glucosyltransferase activities at the third and fourth days. Histochemical observations confirmed chemical analyses for lipids and glycogen.
