Development of a peptide-generated antibody to rabbit hemorrhagic disease virus 2 VP60 and its immunohistochemical application in natural cases.
Rabbit hemorrhagic disease virus 2 (RHDV2) has spread across the United States infecting and causing death in domestic and wild rabbits. Immunohistochemistry (IHC) would be a useful tool for the detection of RHDV2 antigen in tissues as it is inexpensive and readily achievable in most diagnostic laboratories. However, there is no readily available antibody for this purpose. To fill this void, we generated an RHDV2 capsid protein VP60-specific antibody in chicken eggs and validated the antibody using formalin-fixed tissues from 5 domestic rabbits naturally infected with RHDV2. Viral antigen was detected immunohistochemically in various tissues, most prominently in hepatocytes and macrophages in liver, and in macrophages in spleen and cecal lymphoid tissue. Intravascular mononuclear cells in lung and renal tubular and biliary epithelium also were immunolabeled. Both nuclear and cytoplasmic immunolabeling were observed. This peptide-generated antibody is a potentially useful tool as an adjunct to reverse-transcription PCR or in situ hybridization for detection of RHDV2 in tissues.
期刊介绍：
The Journal of Veterinary Diagnostic Investigation (J Vet Diagn Invest) is an international peer-reviewed journal published bimonthly in English by the American Association of Veterinary Laboratory Diagnosticians (AAVLD). JVDI is devoted to all aspects of veterinary laboratory diagnostic science including the major disciplines of anatomic pathology, bacteriology/mycology, clinical pathology, epidemiology, immunology, laboratory information management, molecular biology, parasitology, public health, toxicology, and virology.
