Resumen

El clima subtropical del Paraguay es propicio para la proliferación de vectores como las garrapatas que son responsables de la transmisión de muchas enfermedades como la hepatozoonosis canina. Esta enfermedad, ocasionada por un protozoario del genero Hepatozoon spp. transmitida por Riphicephalus sanguíneus (garrapata marrón) cuando esta es ingerida por el huésped intermediario (el perro), se presenta con síntomas variables como fiebre, emaciación, letargia, anorexia, dolor muscular, anemia y linfoadenapatias. Durante el transcurso de un año, se diagnosticaron cinco casos de hepatozoonosis en caninos de edades de 45 días a 24 meses, por medio de frotis de sangre periférica y medula ósea teñidos con Giemsa. Estos hallazgos se dieron en el Centro Veterinario “Don Perro” de la Ciudad de Asunción, Paraguay donde los pacientes acudieron bajo sospecha de otras patologías. Tres de los pacientes provenían de la Ciudad de Asunción, uno de la Ciudad de Encarnación al sur del país en la frontera con la Argentina y el último de la Ciudad de Guarambaré (a 32 km de la Ciudad de Asunción). Estos son los primero hallazgos de Hepatozoon spp. en el país. Todos los pacientes fueron tratados y respondieron favorablemente al tratamiento. La identificación de este protozoario es muy importante ya que pasa a formar parte de la lista de enfermedades transmitidas por vectores emergentes en el Paraguay como la ehrlichiosis y debe ser tenida en cuenta por lo veterinarios.

Abstract

The subtropical climate of Paraguay favors to the proliferation of vectors such as ticks, responsible for the transmission of many diseases such as canine hepatozoonosis. This disease, caused by a protozoan from genus Hepatozoon spp. and transmitted by Riphicephalus sanguineus (brown tick) when ingested by the intermediate host (dog), it is presented with varying symptoms such as fever, emaciation, lethargy, anorexia, muscle pain, anemia and lymphadenopathy. Along one year, five cases of hepatozoonosis were diagnosed in dogs aged 45 days to 24 months, using peripheral blood smears and bone marrow stained with Giemsa. These findings took place in the Veterinary Practice 'Don Perro' located in Asuncion City, Paraguay where patients attended with suspicions of other diseases. Three of the patients were from Asuncion, one patient came from Encarnación, in the south of the country in the border with Argentina and the last came from Guarambaré City (32 km from Asuncion). These are the first findings of Hepatozoon spp. in Paraguay. All patients were treated and responded favorably to treatment. The identification of this protozoan is very important issue since it has become part of the list emerging vectors borne diseases in Paraguay such as ehrlichiosis and should be taken into account by the veterinarians.
