Tafess K, Ameni G, Dawo F, Sori T., Epidemiology of Caprine Tuberculosis in Mid-Rift Valley, Ethiopia, Onl J Vet Res., 22 (7):578-586, 2018. A cross sectional study of caprine tuberculosis was conducted on randomly selected 626 goats from December 2005 to June 2006 at Adami Tulu Agricultural Research Center and smallholder farmers found around the research center. Single intradermal tuberculin test, post mortem examination of suspected goats and bacteriological culture of the pathogen was carried out to confirm the pathogen. Taking the cut off value at 3.5 millimeters (mm), there was significant difference (p<0.005) in prevalence of caprine tuberculosis between Adami Tulu Agricultural Research Center, and households around Adami Tulu town (3.14% and 10.2%, respectively). The individual animal prevalence was not affected by sex, age, and flock size (p>0.05). Goats under smallholder conditions are 9.36 times at risk of acquiring mycobacterial infection than these under on-station condition. Gross tuberculous lesions were detected in two of the eight tuberculin positive (suspected) goats that were slaughtered for confirmation of tuberculosis lesion, sampling and culture for further confirmation of Mycobacterial growth. Mycobacterial growth and acid fast bacilli were confirmed in those goats with gross tuberculosis lesions. In conclusion, this study has shown the occurrence of tuberculosis in goats in Adami Tulu area. Further studies and confirmation of mycobacterial species and strains which infect goats and probably human are necessary especially in areas that consume raw goats’ milk like pastoral and agro-pastoral areas so that atleast awareness concerning the transmission of the disease from goats milk and meat can be created.
