African buffalo provide insights into the genetics of tuberculosis resistance

Morris Animal Foundation-funded researchers at Oregon State University discovered areas in the African buffalo (Syncerus caffer) genome linked to risk for tuberculosis (TB) infection. The researchers discovered areas of genetic code variation near genes associated with immunity to bacterial infections and demonstrated that these variations correlated with TB resistance. The team published their findings in […]

Badger culling increases ranging behaviour among survivors

A study led by researchers from the Zoological Society of London (ZSL) and Imperial College London has found that culling drives badgers to roam further afield. They say this helps to explain why the practice, intended to reduce bovine tuberculosis (TB) transmission, can sometimes exacerbate the problem instead. Published in the Journal of Applied Ecology, […]

Tuberculosis test differentiates infected from vaccinated animals

Skin tests that can distinguish between cattle that are infected with tuberculosis (TB) and those that have been vaccinated against the disease have been created by an international team of scientists. The findings of the study are published in Science Advances. The traditional TB tuberculin skin test shows a positive result for cattle that have […]

Lactic acid bacteria from badgers display inhibitory activity to BCG

The use of the human tuberculosis vaccine, Bacillus Calmette-Guerin (BCG), in badgers has been suggested as a humane and long-term solution to reduce tuberculosis transmission from badgers to cattle. However, experimental studies show variable protection. Among the possibilities for this variation is that the resident gut bacteria may influence the success of oral vaccination in […]

Cost and scale of field trials for bovine TB vaccine may make them unfeasible

Field trials for a vaccine to protect cattle against bovine tuberculosis (bovine TB) would need to involve 500 herds – potentially as many as 75,000-100,000 cattle – to demonstrate cost effectiveness for farmers, concludes a study published in eLife. Instead, the researchers suggest that the scale and cost of estimating the effect of a vaccine […]

Characterization of Mycobacterium bovis in Mozambique

The most extensive study to date of the genetic diversity of Mycobacterium bovis isolates from Mozambique is reported in PLOS Neglected Tropical Diseases. Bovine tuberculosis (BTB) is of global concern for multiple reasons – the economic impact on animal production, the potential spread to wildlife, and the risk of transmission to humans. While BTB is […]

Roadmap to combat bovine and zoonotic tuberculosis

The Roadmap for Zoonotic Tuberculosis was launched at the 48th Union World Conference on Lung Health, which took place in Guadalajara, Mexico, 11-14 October 2017. Four partners in health, the World Health Organization (WHO), the World Organisation for Animal Health (OIE), the Food and Agriculture Organization of the United Nations (FAO) and the International Union […]

Study reveals dynamic state of bTB epidemiology in Cameroon

Dr Adrian Muwonge and Professor Mark Bronsvoort from The Roslin Institute and colleagues from the UK, Cameroon, Nigeria and Chad conducted the largest molecular epidemiological study of bovine tuberculosis (bTB) in a sub-Saharan African country to understand the incidence and diversity of the disease throughout Cameroon. Their findings are published in Scientific Reports. They collected […]
