Abstract

In comparison with other livestock, tuberculosis (TB) in camels has not been extensively studied in Nigeria. Camels in the hands of Nigerian pastoralists share the livestock ecosystem and are increasingly becoming an important component of the sector. This study was designed to investigate the occurrence of TB lesions and animal-level risk of infection in slaughtered camel carcasses in one of the public abattoirs in Nigeria, from June to August 2016. A total of 212 camel carcasses comprising 82.5% (175/212) males and 17.5% (37/212) females were examined for tuberculous lesions. Of the carcasses examined, 33.5% (71/212) had TB lesions. The occurrence of lesions was most significantly associated with poor body condition (OR = 0.249; CI 0.134–0.454 [p < 0.001]). Distribution among anatomical sites of macroscopic lesions in the infected camels revealed three different pathological patterns as pulmonary (n = 51), abdominal (n = 11), and disseminated (n = 9) forms. Higher prevalence of gross TB lesions in camel carcasses highlights eminent threats to both animal and public health, pointing to an already existing risk of intra- and inter-species transmission of infection.
