Lethal Angiostrongylus vasorum infection in a Hungarian dog

During post-mortem examination of lungs and heart of a 7-month-old female French bulldog, 158 worms were collected from the lung vessels and they proved Angiostrongylus vasorum by their morphological and genetic identification by PCR. The histopathological investigation found a multifocal interstitial inflammation characterized by numerous lymphocytes and a smaller number of plasma cells and eosinophils whilst L1 stage larvae could be seen inside dilated alveoli. We suggested a lethal angiostrongylosis supposed to lead to a fatal effect. Our report attracts attention to the presence of the nematode A. vasorum as causative agent of canine cardiopulmonary disorder in the south-western region of Hungary.
