Aelurostrongylus abstrusus

Aelurostrongylus abstrusus is a species of nematode from the family Angiostrongylidae.

The Aelurostrongylus abstrusus is a cosmopolitan parasite found to be living in the bronchi and alveoli of the lungs of infected cats. Those infected tend to not show many symptoms, if any, as the infection is asymptomatic, leading to shorter lifespans of cats that have been infected. This parasite is typically found in Europe, but also can be found in Africa, Australia, and North and South America.
