Some Aetiological And Epidemiological Observations Of Infectious Keratoconjuctivitis In The Bovine In Kabete Area Of Kiambu District, Kenya.

Abstract

An investigation on the bacterial organisms isolated from clinical field cases of infections bovine Keratoconjuctivitis (IBK) was carried out from data obtained from the large Animal Clinic of the Faculty of Veterinary Medicine, Kabete, covering a period of 10 years (1978-1988). The main bacterial organism isolated was (Moraxella bovis). Other bacterial organisms isolated were (Neisseria spp, Corynbacteria, Strptococcus, Staphylococcus) and (E. coli). In three outbreaks of IBK the prevalence of thedisease was higher in the (Bos taurus) adult cow (30 percent) and calves (67 percent) than in the (Bos taurus) adult cows (4.5 percent) and calves (30.5 percent). The disease was more severe in (Bos taurus) animals than in the Bos indicus cattle. The results of the study showed than (M. bovis) is probably the main pathogen of IBK at Kabete area, and that IBK is not an economically important disease in Bos inducus as it is in the (Bos taurus) cattle.
