Body weights and blood biochemical values in chickens infected with reticuloendotheliosis virus (REV)-HI, a Korean isolate, were studied. REV-HI causes severe body weight depression in chickens inoculated but not in chicken contact-infected. Body weights of infected chickens in 3, 4, and 5 weeks after infection were 78%, 76% and 65% of those of control respectively. Blood glucose levels in REV-infected chickens were extremely high compared with those in control (226±21 vs. 814±91.3 mg/dl in week 2) during the experiment period. Triglyceride levels in REV-infected chickens were significantly higher in week 2 and 3, whereas in week 4, REV-infected chickens showed significantly lower levels than the control. Blood lipase, amylase and alkaline phosphatase levels of REV-infected chickens in week 2 were significantly higher, whereas cholesterol, magnesium and calcium values in week 4 were significantly lower than the control. Other blood biochemical values such as alkaline aminotransferase, aspartate aminotransferase, and γ-glutamyltransferase were nonsignificantly different from the control. These above results suggest that weight depression by REV may be related with increase of blood glucose, which indicated that REV-infected chickens could not use blood glucose as energy source.
