Abstract

Background: Mycoplasma mycoides subsp. mycoides is the causative organism of contagious bovine pleuropneumonia (CBPP). It is a trans-boundary disease (TAD) and endemic in Nigeria causing serious financial loss.
Aim: This study was undertaken to isolate and confirm the presence of Mycoplasma mycoides subsp. mycoides (Mmm) in cattle from three selected South-Eastern states of Nigeria.
Method: A total of Ninety (90) bovine samples (25 pleural fluids and 65 lung tissues) suggestive of CBPP were collected from different abattoirs in the three selected South-eastern states of Nigeria (Anambra, Enugu and Imo), for the isolation of Mmm cultural method was employed, whereas for confirmation Polymerase Chain Reaction (PCR) approach was used. The collected samples were cultured on Pleuropneumonia like organism (PPLO) agar according to specific protocols.
Results: Twenty five (25) of the samples (lungs and pleural fluid) were positive for Mmm on PPLO agar giving an isolation rate of 27.7%. Only twenty one (21) of the isolates were further confirmed using PCR. The PCR amplification of the isolates produced a product of 1.1kbp which is specific for Mmm. No positive isolates were recovered from Imo state.
Conclusion: This study confirms the presence Mmm the causative organism of CBPP in South east Nigeria. It is recommended that active surveillance and vaccination protocol should be undertaken in the region for the control and prevention of this disease.

Key words: Cattle; CBPP; Mycoplasma mycoides subsp. mycoides; Polymerase chain reaction
