Cattle-killer: Two parasites are better than one

23 marzo 2015

An international team of scientists has quantified, for the first time, how co-infection by parasites significantly reduces the severity of the African cattle-killing disease East Coast fever. In east and central Africa, East Coast fever is spread when a tick bites a cow and injects the parasite Theileria parva (T. parva) through its saliva. The resulting disease attacks white blood cells, similar to a fast-moving lymphoma in humans, killing more than a million cattle each year.
