Morphology of Rangelia vitalii parasitic stages in samples from naturally infected dogs
The rangeliosis is a tick-borne disease affecting domestic and wild canids caused by Rangelia vitalii and transmitted by the tick Amblyomma aureolatum. The disease has been diagnosed in southern Brazil since the beginning of XX century, and recently in Argentina and Uruguay which could be related to an increase of the distribution area of the parasite and susceptible hosts. The parasite is an intracellular apicomplexan protozoon closely related with Babesia spp. in phylogenetical studies, however it showed differences in the life cycle. Parasitic stages have been observed in monocytes, erythrocytes and neutrophils, and in endothelial cells from several organs as well as free on plasma. The present study describes the morphology of 4 different parasitic stages observed in blood samples from naturally infected dogs in Argentina.

La rangeliosis es una hemoparasitosis causada por Rangelia vitalii y trasmitida por la garrapata Amblyomma aureolatum, que afecta a perros y otros cánidos silvestres. La enfermedad ha sido diagnosticada en Brasil desde principios del siglo XX y recientemente en Argentina y Uruguay, lo que podría indicar un aumento del área de dispersión del parásito en los últimos tiempos. El parásito es un protozoo intracelular Apicomplexa que está emparentado filogenéticamente con Babesia spp. aunque presenta diferencias en su ciclo parasitario. Se han observado formas parasitarias dentro de eritrocitos, monocitos, neutrófilos y en el endotelio capilar de diversos órganos como así también libres en plasma. El presente trabajo describe morfométricamente cuatro formas parasitarias (o estadios), observadas en sangre de caninos naturalmente infectados por Rangelia vitalii en Argentina.
