[Concurrent vulvovaginitis, respiratory syndrome and keratoconjunctivitis in calves]

Studied was a disease course in calves caused by the IBR/IPV virus with symptoms characteristic of vulvovaginitis, respiratory distrubances and keratoconjunctivitis. Concurrent infections of such type were observed primarily in several-month-old calves (aged from 6--7 weeks to 6 months). In older calves (aged 1--2 years) vulvovaginitis predominated, it being more rarely associated with changes typical of pneumonia, and, as an exception accompanied by keratoconjunctivitis. Dairy cows exhibited predominatly the chronic form of vulvovaginitis. Isolated were 16 strains of the IBR/IPV virus showing properties analogous of those of the standard Oxford strain. Demonstrated were specific IBR/IPV antibodies in calves, cows and bulls (from 24.5 up to 50 per cent). The problem is discussed of the correlation between sterility in cows showing the presence of the IBR/IPV virus and the symptoms of vulvovaginits as well as the presence of hypospermia and balanoposthitis in bulls harbouring the virus infection.
