Replication of five bovine respiratory viruses in cultured bovine alveolar macrophages
Abstract
The replication of five bovine respiratory viruses in cultured bovine alveolar macrophages (BAM) was investigated. The bovine herpesvirus DN-599 strain did not cause cytophatic effect (CPE), extracellular virus and intracellular antigen were not demonstrated. Although a small number of bovine respiratory syncytial virions were consistently released and about 1 percent of the BAM were fluorescence antibody (FA) positive the virus caused no CPE. Infectious bovine rhinotracheitis virus caused CPE at an input multiplicity of about 0.5, and 5 percent of the BAM were FA positive. Both bovine parainfluenza-3 and bovine viral diarrhea viruses caused CPE, infective virions were released and considerable proportions of the BAM were FA positive.
