Vet has animal TB scare

Jonathan believes he caught TB from a wildebeest

"He's one of more than 100,000 people who catch tuberculosis from animals each year - an issue the World Health Organization says has been ignored for decades.

The brutal infection led to him losing nearly 7.5kg in weight as it settled in his chest.

Jonathan was testing stress levels in wildebeest near Kruger National Park in South Africa in 2013 when he thinks he was infected."
