Anaplasma Phagocytophilum, Borrelia Burgdorferi Coinfection
(NY) Anaplasma phagocytophilum and Borrelia burgdorferi coinfection is likely in an 8 month old TB colt that presented with edema in all 4 legs. EDTA blood was positive by PCR, confirming the Anaplasmosis. Both Osp C and Osp F antibodies against Borrelia burgdorferi (lyme disease) were detected in the Lyme Multiplex assay, which is an indicator of subacute infection. Additionally, a Serum Amyloid A test was also requested and it was markedly elevated at 1391 ug/mL, with 0-8 being the typical reference interval.
