Canine Heartworm Disease is a parasitic disease caused by the nematode Dirofilaria immitis. The adult forms are found mainly in the pulmonary arteries and the right heart of canids. This nematode is transmitted by intermediate hosts which are blood suckling mosquitoes. Canine Ehrlichiosis is a disease of domestic and wild canids, caused by the rickettsia Ehrlichia canis, that infects mononuclear cells. This microorganism is transmitted by an arthropod vector, the brown dog-tick Rhipicephalus sanguineus. The objective of this assay was to determine the prevalence of Dirofilaria immitis and Ehrlichia canis in dogs of Chorrillos, La Molina and San Juan de Miraflores districts, which are adjacent to naturally stagnated waters. Blood samples were taken from 140 dogs chosen randomly without regard of breed, age and sex from February to May, 2001. The diagnosis was made by the detection of the ...

La Dirofilariosis Canina es una enfermedad parasitaria, provocada por el nemátode Dirofilaria immitis. Sus formas adultas se alojan principalmente en las arterias pulmonares y en la parte derecha del corazón de los caninos, y se transmite por hospederos intermediarios, mayormente mosquitos hematófagos. La Ehrlichiosis Canina es una enfermedad de los caninos, cuyo agente etiológico es la rickettsia Ehrlichia canis que infecta intracitoplasmáticamente a los monocitos circulantes, y se transmite por un artrópodo vector, “la garrapata marrón del perro” Rhipicephalus sanguineus. El objetivo de este estudio fue determinar la prevalencia de Dirofilaria immitis y Ehrlichia canis en los distritos de Chorrillos, La Molina y San Juan de Miraflores, que son colindantes con aguas naturalmente estancadas. Se recolectaron muestras de sangre de 140 caninos al azar sin distinción de raza, eda...
