Investigations between 1975-78 established that a combination of disease, namely anthrax, and excessive numbers of predators, especially Lion, were responsible for the sharp decline in wildebeest numbers. On average, 62 % of all wildebeest carcases tested positive for anthrax, while predators were not susceptible to anthrax. The levels of other disease and parasites were low.
