Aelurostrongylosis in Cats

Aelurostrongylus abstrusus (A.a.) is a parasite with a indirect life cycle of a lung parenchyma in the cat. Its predominant sites are terminal bronchioles and alveolar ducts. In this study we have examinated two population of cats. The first group consisted of feral cats (n=50) in the rural areas of County of Zagorje (Nortwestern Croatia), and the second group encounted cats from the urban area of City of Zagreb. For the second group data was compilated from fecal examination from the Department of Parasitology and the histopathologycal and gross pathological finding on cats lungs at the Department of General Pathology and Pathological Morphology Faculty of Veterinary Medicine, University of Zagreb. In the first group histopathological examination was carried out and the A.a. was diagnosed in 22% (n=11), and in the second group A.a. was diagnosed in 0,4% (n=2) of the fecal examination and in eight year period (1990-1998) and 3,9% (n=5) on histopathological examination of cats’ lungs also, in the same eight year period. In most of the cases histopathological examination revealed alveoli, bronchioli and alveolar ducti filled with eggs and larvae of A.a., disruption of alveolar septae, cellular infiltrate (mostly eosinophyls, macropahges, lymphocytes and few multinucleated giant cells. Frequently, peribronchial cell infiltration with the same cellular type, a hyperplasia and hypertrophy of smoothe muscle of pulmonic arteries. This study also brings literature overview on Aelurostrongylus abstrusus.
