Resumen
Las condiciones propias de un país tropical como Costa Rica representan grandes ventajas para la
distribución y actividad de las garrapatas, así como facilita que exista una serie de hospedadores para
este tipo de ectoparásitos. Ambos factores inciden en la presentación y prevalencia de enfermedades
vectoriales zoonóticas. En el presente trabajo se presentan los principales resultados obtenidos en las
investigaciones realizadas durante los últimos diez años en la Escuela de Medicina Veterinaria, en las
cuales se ha determinado la presencia, se ha estimado la prevalencia y se ha establecido la importancia,
en la salud pública, de agentes rickettsiales (Ehrlichia spp., Anaplasma spp. y Rickettsia spp.), piroplasmas
(Babesia spp., Theileria spp.), y Hepatozoon canis en animales domésticos (caninos, felinos, equinos
y ovinos), animales silvestres (mapaches, pizotes, venados cola blanca) y garrapatas de nuestro país.
Además, se presentan los resultados obtenidos en un estudio serológico de donadores de sangre; en
especial, la identificación de un nuevo genotipo de Ehrlichia canis hallado en ellos. Finalmente, se
discute sobre la diseminación, transmisión y curso de las diferentes enfermedades, como también sobre
el diagnóstico, el tratamiento y los estudios que hacen falta para establecer las medidas de control
apropiadas a adoptar para el control de estas enfermedades en nuestro país.

In addition, we present the results obtained in a serological study of blood donors; in particular, the the identification of a new genotype of Ehrlichia canis found in them.
