“…Genetically, ten species of the genus Brucellahave been documented and they include B.abortus, B. melitensis, B. suis, B. ovis, B. canis, and B. neotome, B pinipedialis, B ceti, B muris and B inapinata. Of these Brucella abortus is the species of Brucella documented to cause brucellosis in horses (Kaltungo et al, 2013). Brucellosis has been reported in many animal species in Nigeria (Falade et al, 1975;Okoh et al, 1978;Falade and Shonekan, 1981;Adamu and Ajogi, 1995;et al, 2010;Ehiziboloet al, 2011;Ardo and Abubakar, 2016;Baba, 2016;Tijani et al, 2017;Kaltungo, 2018;Njoga et al, 2018;Ado, 2019;Baba, 2019;Buhari, 2019). These reports seem to indicate that brucellosis is endemic and problematic in Nigeria.…”
