Epidemiology of small ruminant tuberculosis

Prevalence of Mycobacterium Avium Complex Infection According to the CIDT test result of the avian tuberculin skin reaction, the overall animal prevalence of Mycobacterium avium complex infection was 2.

This scenario, among other causes, is due to the role of the wild and domestic reservoirs of the disease. View at Google Scholar D. Transmission of tuberculosis caused by Mycobacterium caprae between dairy sheep and goats. Both methods were described in detail in previous publication [ 22 ]. Each animal was dewormed with antihelmintic drug after testing.

Ameni contributed to study design, data collection, data analysis, and interpretation and critically revised the paper. Study Animals For the CIDT test, small ruminants above the age of six months having no clinical symptom of any disease were included.

Duplicates of LJ media were used; one enriched with sodium pyruvate, while the other was enriched with Epidemiology of small ruminant tuberculosis. The isolation of the Mycobacterium tuberculosis in goat indicates the need for further studies to understand the interspecies transmission dynamics of Mycobacterium tuberculosis and the role of small ruminants in the epidemiology of human tuberculosis in pastoralist setting where potential epidemiological risk factors for infection and transmission between livestock and human exist.

Kassa contributed to the design of the study, participated in collection, analysis, and interpretation of data, drafted and revised the paper. Study animal-related information on each tested sheep and goat such as sex, age, body condition score, lactation and reproductive status, and parity number was collected and recorded at the time of the test.

Whenever, colonies were seen, subculturing and Ziehl-Neelsen staining were performed to confirm the presence of acid fast bacilli. In lowland pastoral area where the large population of goats and sheep exists, the status of the disease is unknown.

Whenever, colonies were seen, subculturing and Ziehl-Neelsen staining were performed to confirm the presence of acid fast bacilli. These conditions are potential risk factors for transmission of zoonotic diseases such as TB of animal origin to human or vice versa.

When the change in skin thickness was greater at PPD-A injection site, the animal was considered positive for mycobacteria species other than Mycobacterium tuberculosis complex. In general, similar to the previous studies carried out in cattle and camel of pastoral regions of Ethiopia [ 1820 — 2236 ] which have indicated the endemic nature of tuberculosis in these species, the result of this study also indicated the importance of tuberculosis in small ruminants of Afar Pastoral Region which further emphasizes the need to design a feasible national TB control strategy in livestock of the country.

Postmortem Examination Tissues with suspicious lesions from five slaughtered tuberculin reactor goats were collected aseptically from the lung lobes left apical, left diaphragmatic, right apical, right cardiac, right diaphragmatic, and right accessorylymph nodes of the head retropharyngeal and mandibularlymph nodes of lungs mediastinal and bronchialand mesenteric lymph nodes.

The region shares common international boundaries with Eritrea in the northeast and Djibouti in the east, and it is characterized by an arid and semiarid climate with low and erratic rainfall [ 23 ].
