title: Seroepidemiological studies on human pulmonary dirofilariasis in Spain.
abstract: Preliminary data are presented on a serological survey of the human population of an area with a high prevalence of Dirofilaria immitis infection in dogs. Five per cent of the sera were positive for IgG. Simultaneous radiological study revealed a pulmonary nodule in one of the positive patients, and in this case the evolution of IgG and IgM levels was followed over a period of three months. None of the positive sera reacted with Toxocara canis antigens.
