TUBERCULOSIS: Bovine TB in South Africa

Emergence of bovine
tuberculosis (TB) in wildlife in
southern Africa has implications not
only for the conservation of the wildlife
species affected but also for
the health of humans and livestock
living at the wildlife–livestock–human
interface. Bovine TB in South
Africa’s Kruger National Park was
fi rst found in African buffaloes (Syncerus
caffer) in 1990 and likely
entered the park by cattle-to-buffalo
transmission. Bovine TB infection
has been spreading northward;
in 2003, infection was confi rmed in a
buffalo ≈60 km south of the Limpopo
River. In 2005, a case was confi rmed
only 6 km south of the river. In 2008, we isolated
Mycobacterium bovis from African
buffaloes in Zimbabwe
