Babesia divergens

Species of single-celled organism

Babesia divergens is an intraerythrocytic parasite, transmitted by the tick Ixodes ricinus. It is the most common cause of human babesiosis. It is the main agent of bovine babesiosis, or "redwater fever", in Europe. Young cattle are less susceptible. The current emphasis in Europe on sustainable agriculture and extensification is likely to lead to an increase in vector tick populations with increased risk of infection. B. divergens is also prevalent in cottontail rabbits on Nantucket Island, Massachusetts, USA.
