A Winter Epizootic of Infectious Bovine Keratoconjunctivitis
Journal of the American Veterinary Medical Association, 1970SUMMARY An epizootic of infectious bovine keratoconjunctivitis (ibk) occurred during winter in a Hereford herd. The factors contributing to this epizootic were: (1) Moraxella bovis infection in the eyes and nares of the cattle and (2) increased ultraviolet radiation of the cornea because of reflection from fresh snow.

The Role of Environmental Factors in the Epidemiology of Infectious Bovine Keratoconjunctivitis
Veterinary Clinics of North America: Food Animal Practice, 2021Environmental factors that contribute to the pathogenesis of infectious bovine keratoconjunctivitis (IBK) include face flies, ultraviolet (UV) radiation, and mechanical irritation from plant awns or dust. Limited research has shown face fly control to be associated with lower incidence of IBK.

Infectious bovine keratoconjunctivitis: Evidence for general immunity
American Journal of Veterinary Research, 1983SUMMARY A study was conducted to determine whether acquired immunity to Moraxella bovis during episodes of infectious bovine keratoconjunctivitis (ibk) was local or general. Twelve calves (principals) were exposed to M bovis in the left eye by conjunctival sac instillation on day 1 and in both eyes on day 21.

A national survey of the occurrence of infectious bovine keratoconjunctivitis
Australian Veterinary Journal, 1982SUMMARY A national mail survey of 4880 beef and dairy producers was undertaken to record details of infectious bovine keratoconjunctivitis. One thousand four hundred and fifty eight (29.8%) questionnaires were returned. The survey confirmed the widespread nature of the disease with higher prevalence in the summer months, in calves and dairy cattle, and

SUMMARY Eyes of cattle were exposed to Moraxella bovis organisms and infectious bovine rhinotracheitis (ibr) virus by conjunctival sac instillation under different schedules. In one experiment, the eyes of 10 cattle were exposed to M. bovis and 41 days later to ibr virus.

Infectious Bovine Keratoconjunctivitis Management
American Association of Bovine Practitioners Conference Proceedings, 2007Infectious bovine keratoconjunctivitis is a disease that affects many herds in the US, however, the epidemiology of the disease is complicated and control is frustrating for many producers. This article discusses putative causes of IBK and approaches to understanding the causes of success and apparent failure in IBK control programs.

Applying Concepts of Causal Inference to Infectious Bovine Keratoconjunctivitis
Veterinary Clinics of North America: Food Animal Practice, 2021Establishing causation, otherwise known as causal assessment, is a difficult task, made more difficult by the variety of causal assessment frameworks available to consider. In this article, Bradford Hill viewpoints are used to discuss the evidence base for Moraxella bovis and Moraxella bovoculi being component causes of infectious bovine ...

SUMMARY The effects of a modified-live infectious bovine rhinotracheitis virus vaccine (administered ocularly or intranasally) on experimentally induced infectious bovine keratoconjunctivitis were evaluated. The modified-live infectious bovine rhinotracheitis virus vaccine was administered to 13 male Holstein calves (intranasally in 4 and ocularly in 9;

Effectiveness of two commercial infectious bovine keratoconjunctivitis vaccines
American Journal of Veterinary Research, 1990SUMMARY Two commercially available infectious bovine keratoconjunctivitis (ibk) vaccines were evaluated for their effectiveness in protecting cattle from disease caused by experimental challenge exposure and natural transmission of Moraxella bovis infections.

Development of a laboratory animal model for infectious bovine keratoconjunctivitis
Research in Veterinary Science, 1982Guinea pigs, gerbils, voles, golden hamsters and Chinese hamsters exposed to experimental infection with Moraxella bovis by ocular instillation or associated routes showed transient infections only and no clinical signs. Five strains of mice were of similarly low susceptibility but another, the C57 Bl strain, was relatively susceptible and treatment ...
