title: Comparison of a putative second serotype of chicken infectious anemia virus with a prototypical isolate II. Antigenic and physicochemical characteristics.
abstract: A putative new serotype of chicken infectious anemia virus (CIAV) isolated from 17-wk-old broiler breeder pullets was compared with a known, previously characterized CIAV isolate, the Del-Ros strain. Physicochemical characteristics evaluated induded thermal stability, size, pH, and chloroform sensitivity. Physicochemically, CIAV-7 was identical to CIAV. The virus isolates were compared antigenically by enzyme-linked immunosorbent assay, virus neutralization, immunofluorescence assay, and western blot. All four serologic assays demonstrated that CIAV-7 is antigenically distinct from the Del-Ros strain of CIAV. Additionally, polymerase chain reaction (PCR) and Southern blot were used to determine if there were similarities in genome sequence between the two viruses. CIAV-7 could not be detected with CIAV-specific PCR primers or a with CIAV-specific probe by Southern hybridization.
