Abstract
PurposeBovine tuberculosis (bTB) is infectious chronic disease of animals mainly caused by bacillus Mycobacterium bovis. It is known endemic disease of cattle in Ethiopia. In the current study sites, there is little information on bovine tuberculosis. Thus, this study was aimed to assess public awareness; and estimate prevalence and potential a risk factors of bovine tuberculosis.MethodsA cross-sectional study was conducted, November 2018 to May 2019, on dairy cattle randomly selected from smallholder farms of Arba Minch Zuria and Chencha districts. Comparative intradermal tuberculin test (CIDT) was used in the diagnosis of bTB in dairy animals. CIDT was administered to 221 dairy cattle. Questionnaire survey was performed on 110 smallholders to assess risk factors accountable for the event of bTB in human population.Results8.2% animal level prevalence of bTB was documented in the study sites. Dairy cattle with age of 4 to 8 eight years were 34% more likely to be affected by bTB less than 4 years age cattle (OR=1.34). However, factors like housing, body condition, herd size and parity were not significantly related with the event of bTB. The assessment of bTB awareness was shown 29.7% participants knew that cattle could be infected, and 13.4% of the respondents believed that it can spread from animal to human and vice versa. Besides, 66.1% of participants had habit for consumption of raw milk and soured milk products. Moreover, respondent’s attitude about zoonoses and consequences of bTB was risky.ConclusionPresent study discloses that bTB is animal health problem affecting dairy cattle in Gamo zone, Southern Ethiopia. Based on the current findings, public awareness creation, bovine tuberculosis test and segregation strategy should be applied to minimize the public health hazards and risk factors for bovine origin tuberculosis.
