phenylephrine-hydrochloride and Keratoconjunctivitis

Bovine infectious keratoconjunctivitis, which is caused by Moraxella bovis, occurs perennially in all cattle-raising areas. Disease may occur any time during the year but manifests itself often during summer when disease-enhancing factors such as ultraviolet radiation and fly population are increased. Although some recent research findings indicate that cattle can be immunized against the disease, many problems have to be overcome before the cattle industry can benefit from such immunization. Some pressing problems relate to lack of cross-protection between vaccines of different strains of M bovis, resistant or resilient carrier states, and how these factors affect vaccination regimens undertaken. Though cattle vaccinated with 1 strain are somewhat protected against subsequent challange by the same strain, protection against heterologous strains has not been demonstrated. In most herds, cattle harbor M bovis, and these carriers may serve as a source of infection.

Daily injection of 2-deoxy-D-glucose (2-dG) had no protective effect against respiratory tract infection in calves caused by infectious bovine rhinotracheitis virus. It also did not reduce the severity of this infection. Ocular instillation of the drug, however, markedly reduced the severity of viral-induced conjunctivitis and keratoconjunctivitis. The drug was effective when given at the time of ocular infection or after clinical conjunctivitis developed.

An outbreak of ataxia, blindness, respiratory disease and kerato-conjunctivitis occurred in October 1972 in a beef feedlot in Cyprus. Fifteen animals died and 10 that were severely ataxic were slaughtered; many animals became blind. There was no opportunity to isolate virus when the disease was active but in March and October 1973 infectious bovine rhinotracheitis (IBR) virus was isolated from cattle after they had been treated corticosteroids to stimulate virus excretion. It is probable that IBR virus caused the disease. This is the first report of the isolation of IBR virus from cattle in Cyprus.
