“…In our observations, the herd prevalence of BTB is much lower compared to other authors (Kazwala et al 2001; Omer et al 2001; Ameni et al 2003; Oloya et al 2006, 2007; Shitaye et al 2006; Munyeme et al 2008; Fetene and Kebede 2009; Regassa et al 2010) in the cattle herds in Ethiopia and the different countries of the region. This could be due to difference in agro-ecological zones and production systems.…”

“…However, various other results were reported from Pakistan (2.4% in goats; Javed et al 2010), Eritrea (14.5% in cattle; Omer et al 2001), Zambia (6.8% in cattle; Munyeme et al 2009), Tanzania (13.2% in cattle; Kazwala et al 2001), and from cattle in different regions of Ethiopia: 46.8% (Ameni et al 2003), 19% (Shitaye et al 2006), 11% (Ameni and Erkihun 2007), 9.7% (Fetene and Kebede 2009), and 11.6% (Regassa et al 2010). The inter-study variations may be due to differences in management practices, production system, types of animal species and breeds, or differences in ecological zones.…”

“…In Ethiopia, BTB is endemic in cattle. Prevalence varies from 3.5% to 50.0% depending on the geographical areas, the breeds, and the husbandry practices (Shitaye et al 2007; Berg et al 2009; Demelash et al 2009; Regassa et al 2010). Prevalence in traditionally kept zebu cattle varies between 0.9% and 4.0% based on different cutoff values used for interpretation (Tschopp et al 2010).…”

A cross-sectional study of bovine tuberculosis (BTB) detected by the comparative intradermal tuberculin test (CIDT) was conducted in livestock of the Somali region in southeast Ethiopia—in four pastoral associations from January to August 2009. In 94 herds, each of 15 cattle, camels, and goats was tested per herd leading to a total of 1,418 CIDT tested animals, with 421 cattle, 479 camels, and 518 goats. A herd was considered positive if it had at least one reactor. Prevalence per animal species was calculated using a xtgee model for each species. The individual animal prevalence was 2.0% [95% confidence interval (CI), 0.5–8.4], 0.4% (95% CI, 0.1–3%), and 0.2% (95% CI, 0.03–1.3) in cattle, camels, and goats, respectively. Prevalence of avian mycobacterium purified protein derivative (PPD) reactors in cattle, camels, and goats was 0.7% (95% CI, 0.2–2.0%), 10.0% (95% CI, 7.0–14.0%), and 1.9 (95% CI, 0.9–4.0%), respectively, whereby camels had an odds ratio of 16.5 (95% CI, 5.0–55.0) when compared to cattle. There was no significant difference between livestock species in BTB positivity. In the present study, the prevalence of bovine tuberculosis was low in Somali pastoral livestock in general and in camels and goats in particular. The high proportion of camel reactors to avian PPD needs further investigation of its impact on camel production.

“…In central Ethiopia, BTB is endemic in cattle with varying prevalence of 3.5-5.2% in abattoir and 3.5-50.0% in crossbreeds dairy farms (Shitaye et al 2007;Berg et al 2009;Demelash et al 2009;Regassa et al 2010). Tuberculin skin test survey conducted in the three districts among zebu cattle kept traditionally reported an overall prevalence of 0.9% applying the OIE definition and 3.0% using a 2-mm cut-off (Tschopp et al 2009;Tschopp et al 2010).…”

A cross-sectional study of bovine tuberculosis (BTB) was conducted in pastoral cattle herds in southern Ethiopia, from February to August 2008 using the comparative intradermal tuberculin test. The prevalence of BTB and the risk factors for having positive reactor herds were assessed in four pastoral associations in two districts of southern Ethiopia, namely Goro-Dola with 242 cattle in 16 herds and Liben with 231 cattle in 15 herds. A herd was considered positive if there was at least one reactor animal in a herd. The test results were interpreted based on the Office Internationale des Epizooties recommended 4-mm and a recently suggested 2-mm cut-off. The apparent individual animal prevalence of tuberculin reactors was 5.5% (95% confidence interval (CI), 4.0-8.0%) and 7.0% (95% CI, 5.0-10.0%), whereas the true prevalence estimate was 4.4% (95% CI, 0.8-8.0%) and 6.1% (95% CI, 2.6-9.5%), when using the 4-mm and the 2-mm cut-offs, respectively. The overall herd apparent prevalence of tuberculin reactor animals was 41.9% (95% CI, 24.9-60.9%) and 48.4% (95% CI, 30.2-66.9%) with the 4-mm and 2-mm cut-offs, respectively. A positive tuberculin test was associated with the age of animals and the main drinking water sources during dry seasons. In order to investigate the public health risks and the epidemiological importance of BTB in the area, we recommend to include other livestock species (camels and goats) as well as humans in future studies.

“…In most cases, animals play an essential role in maintaining, distributing, and actually transmitting the infection up to varying degrees into the nature. One of the economically significant zoonotic diseases worldwide is bovine tuberculosis (TB) because of serious public health consequences, high cost of eradication programs mainly in developing countries, and trade restriction on animals and their products [1][2][3][4]. It is said to be the leading cause of death by infectious diseases [5].…”

Mycobacterium bovis is the main causal agent of bovine tuberculosis that causes zoonotic tuberculosis in humans. The most common routes of transmission of the agent to human are airborne transmission, consumption of unpasteurized milk, direct contact with infected animals or untreated animal products. Conventional diagnostic methods in combination with modern molecular and immunological techniques should be used for early and accurate diagnosis of the disease. Some of the challenges to tackle and eradicate zoonotic TB in developing countries are having many hosts, absence of early diagnosis, presence of other acute diseases, being economically unable to implement control strategies, and other social and cultural issues. Usually treatment is not recommended in animals but vaccination is carried out in some countries as a preventive measure. Due to the grave consequences of M. bovis infection on animal and human health, it is necessary to introduce accurate control measures to reduce the risk of disease in human and animal populations. Proper food hygiene practices, slaughter of the affected animals in developed countries, and segregation of the suspected animals in developing countries along with stronger intersectoral collaboration between the veterinary and medical professions are important for the control of the disease.
