Background and Aim: Bovine tuberculosis (bTB) still remains a major zoonotic bacterial disease affecting livestock and humans worldwide. The disease remains a poorly managed tropical disease in most developing countries of the world; where in addition to productivity losses and significance in international trade, it posed a major public health threat to both humans and animals. A retrospective study was designed to investigate the occurrence of bTB lesions at Bauchi municipal abattoir.
Materials and Methods: The study utilized abattoir records spanning a period of 10 years (2004-2013). The records indicated that a total of 1,08,638 heads of cattle comprising n = 56,070 males and n = 52,570 females were slaughtered at the municipal abattoir during the study period.
Result: Of these heads, n = 1230 (1.13%) (95% confidence interval [CI]: 1.07, 1.19) had tuberculous lesions. The annual occurrence during the study period varied significantly (p<0.001) from 0.53% (95% CI: 0.40, 0.67) to 1.87% (95% CI: 1.66, 2.10) in 2010 and 2012, respectively. Females had a significantly higher (p<0.001) prevalence of 2.10% (95% CI: 1.98, 2.23) compared with the males 0.23% (95% CI: 0.19, 0.27). The distribution of suspected gross bTB lesions in different organs showed 11.87% in the lungs, 5.93% in the liver, 1.14% in the heart, and 0.49% accounted for generalized bTB. However, none was observed on the lymph nodes and intestines.
Conclusion: It can be concluded that bTB persists in Bauchi State with annual variations during the study period. This study highlights the importance of meat inspection as an important tool for detecting the presence of bTB lesions.
Fulltext Prevalence and burden of gastrointestinal helminthes among grey-breasted helmet guinea fowls (Numida meleagris galeata) encountered in Gombe state, Nigeria

This cross sectional survey was conducted from July to December 2015 in order to investigate the burden of gastrointestinal helminthes among guinea fowls in Gombe, Northeastern Nigeria. A total of six hundred fowls (viscera) were purchased from six randomly selected slaughter slabs. Out of the 600 birds examined, 479 (79.83%; 95% CI: 76.4, 82.9) were found harbouring one or more gastrointestinal helminthes. Of this, 238 birds (39.7%; 35.8, 43.6) were infected by nematode species and 392 birds (65.3%; 61.4, 69.0) by cestode species. A total of nine nematodes and seven cestodes species were recovered from these birds. There was no any trematode observed among the studied birds. The prevalences of the nematodes identified in descending order were: Ascaridia galli 56.7% (52.7, 60.6); Ascaridia numidae 38.0% (34.2, 42.0); Heterakis gallinarum 17.2% (14.4, 20.4); Heterakis meleagridis 8.3% (6.4, 10.8); Strongyloides avium 3.5% (2.3, 5.3); Subulura brumpti 3.2% (2.0, 5.0); Gongylonema ingluvicola 2.2% (1.3, 3.7) and both Dispharynx spiralis and Tetrameres numidae had 0.7% (0.3, 1.7). While for cestodes: Raillietina tetragona 72.8% (69.1, 76.2); Raillietina echinobothrida 67.3% (63.5, 71.0); Raillietina cesticillus 50% (46.0, 54.0); Raillietina magninumida 25.7% (22.3, 29.3); Hymenolopsis cantaniana 17.3% (14.5, 20.6); Davainea nana 4.2% (2.8, 6.1) and the lowest was observed in Choanotaenia infundibulum with 2% (1.2, 3.5). Infection rates did not differ significantly based on sex (P > 0.05). However, the occurrence of mixed infection as compared with single infection was statistically significant in both cestodes and nematodes (P
