Abattoir Based Study on the Pathology of Tuberculosis in Dromedary Camels, Ethiopia
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2019, Vol 19, Issue 2
Abstract
Background: Camels are important sources of milk and meat for the pastoral communities of East Africa as they are adapted to the harsh environment in this region. However, these animals are facing different health constraints including tuberculosis (TB). TB can also be transmitted to pastoralists from camels since their milk is consumed raw and as the pastoralists live in close physical contact with potentially infected camels. However, little data is available on the epidemiology of TB in camels in this region. Methods: This study was undertaken from February, 2014 to July, 2016 to investigate pathological lesions of tuberculosis in camels slaughtered at Akaki abattoir, central Ethiopia. In order to achieve this objective, a cross-sectional study design was used to recruit 2070 camels for pathological investigation. Results: The lesion prevalence of TB in camels slaughtered at Akaki Abattoir was 7.54% (95%CI: 6.45% -8.7%). Statistically significant association (χ2=26.2, p=0.000) was observed between body condition of the camels and prevalence of TB. Multivariate logistic regression analysis revealed that poor body condition was significantly associated [p= 0.000, (Adjusted OR=2.55, 95%CI: 1.743 - 3.734)] as a risk factor for TB in camels. Relatively higher frequency of lesion was detected in female, poor body conditioned, and Borena camels with a proportion of 87.2%, 46.2%, and 84%, respectively. Anatomically, lesion was frequently found in sub-mandibular (54.8%) and retro-pharyngeal (16.94%) lymph nodes. Moreover, severe lesion was observed in sub-mandibular (2.47±0.24), retro- pharyngeal (0.35±0.2) and trachea-bronchial (0.35±0.2) lymph nodes. Conclusion: The present study revealed that the detection of extensive tuberculosis lesions in camels could help to elucidate tuberculosis evidently prevalent in camels. However, the current pathological findings are not conclusive. Therefore, further cultural isolation and molecular characterization of strains causing tuberculosis in camels was recommended.
