Development of an enzyme-linked immunosorbent assay to detect and quantify adenovirus in chicken tissues.
An indirect enzyme-linked immunosorbent assay (ELISA) was developed to detect and quantify avian adenovirus (AAV) in various chicken tissues, including blood. A positive ELISA absorbance value was obtained with suspensions of infected liver tissue that contained less than 100 mean tissue-culture infective doses per gram. A positive correlation was observed between the absorbance values and titer of infectious virus in infected liver tissue. A group-specific antigen common to the 12 serotypes of AAV tested was demonstrated by this ELISA. Because of the high sensitivity and broad-spectrum reactivity, this ELISA could be useful for the study of AAV pathogenesis, for laboratory diagnosis of inclusion body hepatitis irrespective of the serotype of AAV involved, and for screening commercial and specific-pathogen-free flocks for the presence of AAV.
