Babesia microti


Also found in: Wikipedia.

Ba·be·si·a mi·cro·'ti

a malarialike protozoan naturally parasitizing certain rodents (Peromyscus and Microtus spp.) in North America; human cases have been reported in the U.S. The local tick vector is Ixodes scapularis, the numbers and infection levels of which have greatly increased in recent years with the increase in the deer population, which serves as an abundant blood source for I. scapularis.
See also: Borrelia burgdorferi.

Babesia microti

The babesiosis agent, an intraerythrocytic protozoan parasite endemic in rodents, Peromyscus spp and Microtus spp, and which is transmitted to humans via a tick, Ixodes dammini.
 
Diagnosis
Light microscopy of thick smears of peripheral blood.

(bă-bē'zē-ă mi-krō'tī)
A malarialike protozoan naturally parasitizing certain rodents; several human cases have been reported from the islands of Nantucket and Martha's Vineyard and nearby coastal New England. The local tick vector is Ixodes scapularis, the numbers and infection levels of which have greatly increased in parallel with the increase in the deer population, which serves as an abundant blood source for I. scapularis.
