Abstract
Two-week-old gnotobiotic chicks were inoculated in the foot pad with viruses isolated from synovia and synovial membrane-WVU 1464-29H, WVU 1675, WVU 2937, WVU 2986, and WVU 71-212; from digestive tract-reoviruses 24, 25, and 59; or from respiratory tract-reovirus Fahey-Crawley (FC). All viruses induced swelling of the foot pad and inflammatory changes of synovial membrane. Serum from virus-infected chicks had a common agar gel precipitin (AGP) line. On the basis of the plaque-reduction test in primary chicken kidney (PCK) cells, the viruses were classified into 4 major serotypes. All viruses produced cytopathic effects (CPE) in primary chicken tissue cultures. Other than reovirus FC and WVU 1464-29H, all viruses produced CPE in the Vero cell line.
