Active and Latent Ovine Herpesvirus-2 (OvHV-2) Infection in a Herd of Captive White-tailed Deer (Odocoileus virginianus)
Journal of Comparative Pathology(2013)
摘要
Malignant catarrhal fever (MCF) is the clinical manifestation of infection of certain ruminant species with one of a group of pathogenic gammaherpesviruses known as MCF viruses. Cattle and numerous exotic ruminant species are susceptible to clinical disease that may be sporadic or occasionally epidemic in nature. The most common MCF virus worldwide is ovine herpesvirus (OvHV)-2. Reservoir hosts such as sheep, carry and excrete OvHV-2, but do not develop clinical signs, while clinically susceptible species develop severe and often fatal disease. The existence of latent infection in clinically susceptible hosts is poorly understood, but is documented in some ruminant species. Twenty-six animals from a captive herd of white-tailed deer (Odocoileus virginianus) died and were examined from October 2006 to December 2010.
