The occurrence of antibodies to bovine virus diarrhoea,infectious bovine rhinotracheitis and parainfluenza 3 viruses in sera from New Zealand cattle

Abstract

Extract

Despite many viruses having been isolated from bovine respiratory and intestinal tracts, only those of bovine virus diarrhoea (BVD), bovine parainfluenza 3 (PI 3) and infectious bovine rhinotracheitis-infectious pustular vulvovaginitis (IBR) have so far been associated with specific clinical complexes. Serological surveys have demonstrated the wide geographical distribution of all three viruses (Huck, 1962 Hack, R. A. 1962. Some recently isolated viruses from cattle. Vet. Bull., 32: 493–504.  [Google Scholar]; Paterson, 1962 Paterson, A. B. 1962. Virus diseases in calves. Vet. Rec., 74: 1384–1389.  [Google Scholar]; French and Snowdon, 1964 French, E. L. and Snowdon, W. A. 1964. Mucosal disease in Australian cattle. Aust. vet. J., 40: 99–105.  [Google Scholar]; Dawson and Darbyshire, 1964 Dawson, P. S. and Darbyshire, J. H. 1964. The occurrence and distribution in the United Kingdom of antibodies to parainfluenza 3 and infectious bovine rhinotracheitis viruses in bovine sera. Vet. Rec., 76: 111–115.  [Google Scholar]), although so far only IBR has been confirmed as being present in New Zealand (Webster and Manktelow, 1959 Webster, R. G. and Manktelow, B. W. 1959. Some observations on bovine rhinotracheitis in New Zealand. N.Z. vet. J., 7: 143–148. [Taylor &; Francis Online] , [Google Scholar]). However, in view of a previous outbreak of a mucosal-like disease (Salisbury etal., 1961 Salisbury, R. M., Hartley, W. J., Mcintosh, I. G., Hansen, N. F., Te Punga, W. A. and Jamieson, S. 1961. A mucosal disease-like syndrome of cattle in New Zealand. Bull. Off. int. Epiz., 56: 62–79.  [Google Scholar]) together with the frequent occurrence of upper respiratory tract symptoms, it seemed most unlikely that other members of this virus trio would be absent from cattle in this country.
