Spillover of Mycobacterium bovis from wildlife to livestock, South Africa

Jolly Musoke et al. Emerg Infect Dis. 2015 Mar.

Abstract

During August 2012-February 2013, bovine tuberculosis was detected in communal livestock bordering the Greater Kruger National Park Complex (GKNPC) in South Africa. Using spacer oligonucleotide and variable number tandem repeat typing, we identified the Mycobacterium bovis strain endemic in GKNPC wildlife. Our findings indicate bovine tuberculosis spillover from GKNPC wildlife to neighboring livestock.

Location of study area (A, red dot) and location of dip tanks (B) in study of bovine tuberculosis transmission, Greater Kruger National Park Complex, South Africa, August 2012–February 2013. Parentheses used below indicate the shortest distance between individual dip tanks and the game fence, as follows: dip tank A (3.1 km), B (3 km), C (4.2 km), D (7.3 km), E (2.3 km), F (1 km), G (6.1 km), H (5.8 km), I (0.5 km), J (6 km), K (1.2 km), L (1 km), M (4.3 km), N (2 km), O (6.4 km). Blue dots indicate dip tanks sampled; red circles indicate dip tanks at which bovine tuberculosis–positive cattle were detected. Gray boxes indicate observed cattle grazing range for dip tanks at which bovine tuberculosis was detected.
