BABESIA

 

Babesia microti, Babesia duncani (WA1), Babesia divergens and Babesia sp. (MO1) are obligate intra-erythrocytic protozoans transmitted by tick vectors, causing flu-like symptoms as well as a malaria-like illness in humans.  All four agents can be transmitted by blood donor units from asymptomatic donors.


Our IFA slide antigens are all propagated in vitro using human type O erythrocytes to provide the cleanest and most sensitive reactivity possible.


Special note on the use of Babesia duncani (WA1) IFA: Our manuscript is in preparation for the use of these B. duncani IFA slides for detection of recent tick bites in humans and dogs. Screening sera at 1:64 detects recent tick bites in both IgG and IgM class antibody, although the tick may not have been infected. Strong reactivity related to actual B.duncani infection is rare, with less than 1 reported case per year since this species was identified in 1991.
