Babesia microti, Babesia duncani (WA-1) and Babesia sp. (MO1) are obligate intra-erythrocytic protozoans transmitted by tick vectors, causing flu-like symptoms as well as a malaria-like illness. Although B. microti is evident throughout the New World, the ranges of WA-1 and MO1 are much less defined, so we will be producing 3-antigen MIF slides to learn more about the distribution of these three pathogens.
For European and Asian facilities we offer B. divergens and, hopefully, B. venatorum on 2-antigen MIF slides. When B. microti is of interest, we have space to add it to the other two antigens for concurrent testing against all three. As all of our human babesiosis antigens are propagated in vitro using human type "O" erythrocytes we have matching substrates for comparison.
