Bovine bone marrow-derived macrophages were infected in vitro with non-cytopathic or cytopathic strains of bovine viral diarrhoea virus. Infection with both biotypes resulted in a decreased production of tumour necrosis factor alpha upon stimulation with heat-inactivated Salmonella dublin or lipopolysaccharide. Other macrophage functions were not downregulated, indicating that the observed effect was not due to a loss in macrophage viability. The downregulated production of tumour necrosis factor alpha in infected macrophages may contribute to the well-documented immunosuppression in animals infected with bovine viral diarrhoea virus.
