Abstract

Infectious bovine rhinotracheitis (IBR) occurred on three farms adjacent to one another. Conjunctival congestion, lecrimation, palpebral sebum, and rhinorrhea were observed, but no respiratory symptoms appeared at all. On one farm raising 95 cattle IBR attacked 83 cattle in about 10 days. IBR virus was isolated from ocular and nasal swabs from 11 of 19 cattle clinically infected.
At autopsy on cattle showing a high antibody titer, IBR virus was isolated from tonsils and lymph nodes, suggesting that the virus might be discharged from infected cattle for a long time. M. bovis was also isolated from four cattle with severe ophthalmic symptoms which had no abnormality in the cornea.
