Bovine tuberculosis (bTB) is endemic and has a substantial impact on the livestock sector in Ethiopia and other low and middle-income countries (LMICs). With a national emphasis on dairy farm intensification to boost milk production and spur economic growth, the incidence of bTB is anticipated to rise. However, Ethiopia, like other LMICs, lacks a c...

Bovine tuberculosis (bTB) is a threat to cattle health and public safety. The current control programs are hampered by wildlife reservoirs and socioeconomic barriers. Vaccinating cattle with Bacillus Calmette-Guérin (BCG) effectively reduces transmission, offering a potential solution for controlling bTB. A key component of the vaccination strategy...

Continual changes in climate have become a globally alarming phenomenon. Evidence showed that temperature is increasing from time to time globally, linked to the growing concentration of atmospheric energy-trapping gases, potentially creating the so-called greenhouse effect. Greenhouse gases comprise mainly carbon dioxide, N2O, methane, and other h...

Morbidity and mortality of young stock present economic and production challenges to livestock producers globally. In Ethiopia, calf morbidity and mortality rates, particularly due to diarrhea and respiratory disease, are high, limiting production, incomes, and the ability of farmers to improve their livelihoods. In this paper, we present findings...

Bovine tuberculosis (bTB) is one of the top three, high-priority, livestock diseases in Ethiopia and hence, the need for evaluation of potential control strategies is critical. Here, we applied the test-and-segregate followed by cull strategy for the control of bTB in the intensive Alage dairy farm in Ethiopia. All cattle reared on this farm were r...

Background: In the Ethiopian dairy farming system, prevalence of zoonotic diseases such as bovine tuberculosis (bTB) is high in the cattle population. This, combined with some risky milk and meat consumption habits, such as raw milk and uninspected raw meat consumption, poses a considerable risk of zoonotic disease transmission. A survey was condu...

Background Previous work has shown differential predominance of certain Mycobacterium tuberculosis (M. tb) lineages and sub-lineages among different human populations in diverse geographic regions of Ethiopia. Nevertheless, how strain diversity is evolving under the ongoing rapid socio-economic and environmental changes is poorly understood. The pr...

Bovine tuberculosis (bTB) is endemic in cattle in Ethiopia, a country that hosts the largest national cattle herd in Africa. The intensive dairy sector, most of which is peri-urban, has the highest prevalence of disease. Previous studies in Ethiopia have demonstrated that the main cause is Mycobacterium bovis , which has been investigated using con...

The Ethiopian government has several initiatives to expand and intensify the dairy industry; however, the risk of bovine tuberculosis (bTB) spread is a challenge. To assess the rate of expansion and risk factors for transmission of bTB within-herds, we carried out a repeated cross-sectional survey at two time points, 2016/17 and 2018, in three regi...

This report illustrates that calves may be infected with bovine tuberculosis at early age under natural conditions and progression can be rapid. Thus, testing of calves needs to be considered in any control program to reduce the risk of transmission. This report illustrates that calves may be infected with bovine tuberculosis at early age under nat...

Bovine tuberculosis (bTB) is endemic in Ethiopia with higher prevalence in cattle, particularly in the central parts. Spread of Mycobacterium bovis (M. bovis) to wider regions is inevitable in uncontrolled conditions. This study was conducted to explore the pathology, characterize M. bovis strains, and describe genotypic diversity to demonstrate po...

Background: Dairy cattle movement could be a major risk factor for the spread of bovine tuberculosis (BTB) in emerging dairy belts of Ethiopia. Dairy cattle may be moved between farms over long distances, and hence understanding the route and frequency of the movements is essential to establish the pattern of spread of BTB between farms, which cou...

Bovine tuberculosis (BTB) has become an economically important disease in dairy herds found in and around Addis Ababa City and is emerging in regional cities like Gondar, Hawassa and Mekelle because of the establishment of dairy farms in the milk sheds of these cities.

The study was conducted with the objectives of determining the possible causes of pneumonia in the sheep and to characterize the microscopic lesions of concurrent infection of Maedi-Visna with lung worms and other infectious pneumonia. Detailed gross and microscopic examinations were employed on 35 Maedi-Visna seropositive sheep. Out of 35 sheep sl...

Participatory disease surveillance uses a participatory technique for the collection of qualitative epidemiological information within the community observations and existing veterinary knowledge.

Lumpy skin disease, sheeppox and goatpox are high-impact diseases of domestic ruminants with a devastating effect on cattle, sheep and goat farming industries in endemic regions. In this article, we review the current geographical distribution, economic impact of an outbreak, epidemiology, transmission and immunity of capripoxvirus. The special foc...

A cross-sectional study was conducted in three selected Districts of Gambella Regional State (GRS) namely Lare, Itang and Gambella Zuria from March to October 2011 to determine seroprevalence of Contagious Caprine Pleuropneumonia (CCPP) caused by Mycoplasma capricolum subsp capripnemoniae (Mccp) and to identify potential risk factors and to assess...

Mucoid nasal discharge, loss of weight, decreased milk production, diarrhoea, salivation, dyspnoea, fever, lacrimation, bilateral corneal opacity and bloody urine were observed in cattle located in the Arbe Gona district of southern Ethiopia. The disease was associated with a high case fatality rate: diseased cattle died within four to five days af...

This study was carried out with the aim of identifying types of gross and histopathological lesions in lungs of camels slaughtered between October 2009 and April 2010 at Addis Ababa abattoir enterprise, Ethiopia. All camels were originated from Borana and Kereyu areas. A total of 387 slaughtered camel lungs were inspected during the study period. O...

A study was conducted to determine the variation in susceptibility of three Ethiopian sheep breeds (Arsi, Horro and Menz) to experimental infection with Fasciola hepatica. Arsi and Menz breeds of 16 rams each and Horro breed of 14 rams aged between 6 and 8 months were randomly divided into two groups. All rams in the first groups of each breed were...

During fibrosis, the extracellular matrix (ECM) is continuously remodeled and increases in volume due to the production of various proteins. We studied the distribution of tenascin-C (TN-C) and the correlation of TN-C with the necro-inflammatory activity and expression of alpha-smooth muscle actin (alpha-SMA), cytokeratin 7 (CK7), and CD3+ T-lympho...

An attempt was made to determine the live weight, carcass weight and dressing percentage of Issa camels of various age groups raised under natural field condition. The mean live weights estimated from Barymetric measurements (shoulder height, thoracic and abdominal girth) were 131.9 ± 20.3 kg (for calves less than 1 year of age), 211.6 ± 20.2 kg (1...
