Summary

One strain of infectious bovine rhiontracheitis was isolated from calves with respir­atory disease in bovine kidney cell cultures, and purified by plaque forming method. The virus replication was inhibited in the present of 5-iodo 一2'-deoxyuridine. It was stable at PH 7 to 8, but loses activity below PH5, It was inactivated by exposure at 56 °C for 30', and at 60°C for 15', and destroyed by treatment of I M, MgCl, at 50°C, for 30'. 
The isolated virus was serologically related to the cooper strain of infectious bovine rhinotracheitis, It did not agglutinate bovine, goat and sheep red blood cell at 4°C. The precipitin line appeared when anti-lBR-C rabbit serum wasalllow to diffuse toward the isolated virus, but anti-BVD-NADL or anti-Pl,-SF-4 rabbit serum did not react to the isolated virus. 
The isolated virus produced cytopathic effect in BT, BK, AuBEK, ESK, PK-15, and HeLa cell cultures.
