International Clinical Anaplasma

Anaplasma are zoonotic obligate intracellular alpha-proteobacteria of the family Anaplasmataceae. Ticks serve as reservoirs and vectors of anaplasmosis while feeding on both humans and animals. The antibody response to infections by both Anaplasma phagocytophilum and A. platys is primarily directed against outer-membrane protein antigens and is most often detected using standard IFA and MIF methods. Custom formats containing combinations of these Ehrlichia or Anaplasma antigens can be made available. Call or email your needs.

Our IFA slides contain infected cells in a traditional format, while our 2-antigen MIF (depicted below) pairs purified Anaplasma phagocytophilum with purified Ehrlichia chaffeensis in each slide well.

The MIF format removes the vast majority of host cell cytoplasmic, nuclear and membrane constituents that are common sources of “non-specific” fluorescence. Without the need to penetrate the host cell membrane, the IgM antibody assay has the same incubation timing (30 minutes) as the IgG assay. To produce a distict marix for these antigens, we use a sonicated chicken cell suspension that absorbs the Evans’ blue counterstain. The goal of this approach is to produce a reaction that can be immediately classified as either positive or negative, saving valuable technician time and avoiding erroneous results caused by irrelevant fluorescence.

We highly recommend this MIF format for the accuracy of both IgG and IgM antibody titers. You will not see false-positives nor will you see cross-reactivity with Ehrlichia affecting Anaplasma titers.
