Babesiosis causes
Overview
Babesiosis is caused by apicomplexan parasitic organism within the genus Babesia. B. Microti and B. divergens are the two species of Babesia that have been frequently reported as parasitic within human populations. Babesia parasites reproduce in red blood cells, where they can be seen as cross-shaped inclusions (4 merozoites asexually budding but attached together forming a structure looking like a "Maltese Cross") and cause hemolytic anemia, quite similar to malaria.
