Abstract

Records kept in Colorado showed that there were 364 cases of malignant catarrh between 1962 and July 1972, usually sporadic involving between 4 and 9% of cattle in a herd. However, in 1972 an outbreak resulted in the death of 87 beef cattle (37%) in one feedlot. There was no evidence of a particular sex or breed incidence; most cases were 1-2 years old and 74% of cases occurred during the winter. The most frequent signs were fever, photophobia, lacrimation, scleral injection and corneal opacity. In two major outbreaks the cattle were in close contact with sheep.
