RESUMO

Background: Mycoplasma mycoides subsp. mycoides is the causative organism of Contagious Bovine Pleuropneumonia (CBPP). It is a trans-boundary disease and an endemic in Nigeria having caused serious financial loss for the country's economy. Aim: This study was undertaken to isolate and confirm the presence of M. mycoides subsp. mycoides (Mmm) in cattle, from three selected South-Eastern states of Nigeria. Method: A total of 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 by employing cultural method, 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 of the samples (lungs and pleural fluid) were positive for Mmm on PPLO agar giving an isolation rate of 27.7%. Only 21 of the isolates were further confirmed using PCR. The PCR amplification of the isolates produced a product of 1.1 kbp which is specific for Mmm. No positive isolates were recovered from Imo state. Conclusion: This study confirms the presence of Mmm as the causative organism of CBPP in Southeast Nigeria. It is recommended that active surveillance and vaccination protocol should be undertaken in the region for the control and prevention of this disease.

RESUMO

The prevalence of mycobacterial infection among lactating Fulani cows was investigated in the Federal Capital Territory, Abuja and Kaduna State of Nigeria. Tuberculin testing using single comparative intradermal tuberculin test showed a 14.6 % positive, 4 % doubtful, and 81.4 % negative reactors. Mycobacterial infection was found to be present in the nomadic (constantly moving) and seminomadic (limited movement) management systems studied but management showed no significant effect on the prevalence of the disease. However, the prevalence was significantly higher in older age groups than the younger ones (P < 0.05).
