The one-humped camel in tanzania: Attempted introduction by the missionary- explorer david livingstone in 1866

The missionary-explorer David Livingstone imported six camels from India to Zanzibar and thence to what is now southern Tanzania in 1866. His purpose was to test the use of camels for transport and assess their resistance to the disease he believed to be transmitted by tsetse flies which was later discovered to be trypanosomosis. His camels did not live long and died from a combination of extreme ill treatment by their handlers and the effects of the tsetse fly within a few weeks of their arrival on the African mainland.
