Abstract
La piroplasmosis equina (PE) es una enfermedad parasitaria de los équidos(caballos, burros, mulas y cebras) causada por dos protozoos apicomplexos intraeritrocitarios: Theileria equi (antes designado como Babesia equi) y Babesia caballi. Estos parásitos son principalmente transmitidos por garrapatas ixódidas pertenecientes a los géneros Dermacentor, Hyalommay Rhipicephalus; sin embargo, la transmisión puede también ocurrir por transfusión materno-fetal y por vía iatrogénica. Esta enfermedad puede manifestarse de forma hiperaguda, aguda, subaguda o crónica, por medio de signos clínicos variables y no específicos tales como: fiebre (>40ºC),palidez de las mucosas, ictericia, edema periférico, anorexia, pérdida de peso, disminución del rendimiento y esplenomegalia. Los caballos que superan la infección aguda pueden permanecer como portadores de estos parásitos durante largos periodos de tiempo, siendo una fuente de infección para las garrapatas y otros caballos...
Equine piroplasmosis (EP) is a parasitic disease of equids (horses, donkeys, mules and zebras) caused by two intraerythrocytic protozoan parasites within the phylum Apicomplexa: Theileria equi (previously named Babesiaequi) and Babesia caballi. These parasites are mainly trasmitted by ixodidtick species belonging to several genera such as Dermacentor, Hyalommaand Rhipicephalus; however, transmission may also occur vertically in utero and iatrogenically. This disease has a hyperacute, acute, subacute orchronic form; affected animals often show variable and non specific clinicalsigns such as: fever (often exceeding 40ºC), pale mucous membranes, jaundice, peripheral edema, anorexia, weight loss, decreased performance and splenomegaly. Horses can remain carriers of these parasites for a long time after the resolution of acute disease, being a source of infection for ticksand other horses...
