Minding the Herd

To understand the diversity of endemic tuberculosis in Cameroon’s cattle and how it spreads, researchers at The Roslin Institute conducted the largest molecular epidemiological study in a sub-Saharan African country.

They found that instead of high transmittance rates, there was a high prevalence of genetic diversity in strands of the disease—most likely caused by constantly moving the livestock.

499 samples from 380 cattle with and without disease lesions were collected in 4 separate cities. This allowed researchers to predict how and to what extent the disease was transmitted. They agree that a control system for ending bovine TB in Cameroon is greatly needed.
