Feline heartworm (Dirofilaria immitis) infection: first case report of serological diagnosis in Brazil, confirmed by molecular assay.

摘要: The clinical importance of heartworm infection in cats has indeed increased recent years. Dirofilaria immitis been reported worldwide and continues to be regularly diagnosed endemic areas. diagnosis can overlooked easily, especially Brazil, where there is not a specific feline immunodiagnostic test, forcing the veterinarians use test made for canine host. In 2015, 10-year-old female neutered cat was with D. using an antigen serological based on imunocromatography designed dogs. modified Knott negative. As disease progressed, showed signals respiratory distress, such as dyspnoea polypnea addition prostration emaciation, died few weeks after diagnosis. During necropsy, one adult nematode found pulmonary artery. confirmed by molecular amplification, performed worm fragment. This first report dirofilariasis Brazil. A chemoprophylaxis routine should done, done dogs from
