Mycoplasma bovis is the second most important mycoplasmas causing a variety of diseases in cattle worldwide. This study was aimed to report the PCR identification of M. bovis from slaughtered cattle in northeastern Nigeria. Four hundred and eighty (480) samples of lung tissues (180), nasal swab (180), ear swab (60) and pleural fluid (60) were collected from 190 heads of cattle at slaughter in Yola and Jalingo abattoirs in Adamawa and Taraba States, respectively Samples were processed based on standard laboratory protocols. An overall Mycoplasma bovis isolation rate of 0.83% (4/480) was obtained. Based on the states studied, 1 (0.35%) and 3 (1.53%) M. bovis were isolated from Adamawa and Taraba States, respectively with an insignificant association between M. bovis infection and the states sampled (P>0.05). Based on organs/site sampled, 2 (5.40%) isolates of M. bovis were from lung tissues and 1 (2.70%) were from both pleural fluid and ear swab samples. All the 4 isolates were confirmed as M. bovis by the presence of one band of 734 bp. The study had established first isolation of M. bovis from the ear canal of cattle at slaughter in the study area. Therefore, large scale epidemiological studies that will reveal the true prevalence and distribution of M. bovis infection in cattle population in Nigeria are recommended.
