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.
与其他家畜相比，尼日利亚尚未对骆驼结核病进行广泛研究。尼日利亚牧民饲养的骆驼与其他家畜共享畜牧生态系统，并且日益成为该行业的重要组成部分。本研究旨在调查2016年6月至8月期间尼日利亚一家公共屠宰场屠宰的骆驼尸体中结核病病变的发生情况以及动物层面的感染风险。共检查了212具骆驼尸体，其中雄性占82.5%（175/212）、雌性占17.5%（37/212），检查是否存在结核病变。在检查的尸体中，33.5%（71/212）有结核病病变。病变的发生与身体状况差最显著相关（比值比=0.249；置信区间0.134 - 0.454 [p < 0.001]）。感染骆驼宏观病变的解剖部位分布显示出三种不同的病理模式，即肺部（n = 51）、腹部（n = 11）和播散性（n = 9）形式。骆驼尸体中结核病宏观病变的较高患病率凸显了对动物和公众健康的重大威胁，表明已经存在种内和种间感染传播的风险。
