title: Zoonotic Dirofilaria immitis infections in a province of Northern Spain.
abstract: Dirofilaria immitis is the causal agent of canine and feline cardiopulmonary dirofilariasis. Moreover, the existence of canine dirofilariasis implies a risk for human populations living in an endemic area in which, the parasite can cause pulmonary dirofilariasis. The Spanish epidemiological situation is not well understood, lacking data from many central and Northern provinces. In our study, epidemiological data on canine and human dirofilariasis for La Rioja (Northern Spain) have been obtained for the first time. The overall prevalence of D. immitis in dogs was 12% (9% of patent and 3% of occult infections), being 11.6% the seroprevalence of human residents in this province. The geographic distribution of both canine and human D. immitis infections in La Rioja is restricted to humid and irrigated areas near the Ebro Valley River, being absent in the rest of the province where hills and mountains predominate.
