Abstract
Feline norovirus (FNoV) is a potential pathogen of feline gastroenteritis and has two genogroups (GIV and GVI). Few epidemiological studies have been conducted on FNoV. We designed two enzyme-linked immunosorbent assays (ELISAs) to identify genogroup-specific FNoV antibodies for serological surveillance. Analysis of sera from cats experimentally infected with FNoV GIV or GVI and from specific-pathogen-free (SPF) cats confirmed that the two recombinant proteins used in the assay react in a genogroup-specific manner. Of the 183 samples tested, 6.6% were positive for GIV and 26.2% were positive for GVI. Antibodies to both FNoV genogroups were detected in sera collected in 2005, seven years before FNoV was first reported.
期刊介绍：
Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
