Seroprevalence of Leptospirosis in Cattle in Smallholder Livestock Production Systems in Bungoma County, Kenya

Leptospirosis is an important re-emerging bacterial zoonosis of public health importance in Kenya. It is transmitted through contact with contaminated soil, water, or urine of infected animals. The disease is associated with high economic losses which include high cost of diagnosis and treatment, disruption of international trade in animals and animal products and loss of milk production following mastitis among others. In this study, the sero-prevalence of bovine leptospirosis in Kimilili and Mt Elgon Sub-Counties of Bungoma County in Kenya was estimated. A cross-sectional study was conducted between April to July, 2017 where blood serum samples from 200 head of cattle from five wards and one slaughter house using systematic random sampling technique. The samples were then subjected to the Enzyme Linked Immunorsorbent Assay (ELISA) test. The findings show an overall sero-prevalence for leptospirosis in cattle in the study area to be 16%. The sero-prevalence of leptospirosis in the study area by wards is as follows; 10.7% in Kibingei, 12.5% in Kimilili, 17.6 in Maeni, 16.7% in Kamukuywa and 15.6% in Kaptama. The study also reveals that the sero-prevalence was relatively higher in Kimilili Slaughterhouse which recorded 21.0%. The study therefore demonstrates that there is a high sero-prevalence of leptospirosis in cattle in Kimilili and Mt Elgon Sub-Counties, Bungoma County. This study therefore provides critical public health information which is necessary in guiding leptospirosis prevention and control in Bungoma County. It is therefore recommended that strategies for surveillance and laboratory diagnosis of leptospirosis should be initiated in Bungoma County. This will help in providing better estimates of leptospirosis burden in the county.
