Plain-English summary

A 12-year-old male domestic shorthair cat was found to have severe lung and colon issues after showing signs of depression, aggression, and fever. A necropsy revealed that he had a lung infection caused by a parasite called Aelurostrongylus abstrusus, which was also found in the colon. A second domestic shorthair cat of unknown age had similar findings in tissue samples. Unfortunately, both cats had significant health problems due to this parasite, which can lead to serious illness.

Abstract

A 12-year-old male domestic shorthair cat with a history of depression, aggression, and fever was presented for necropsy, and formalin-fixed tissues from a second male domestic shorthair cat of unknown age were submitted for histopathologic examination to the Athens Veterinary Diagnostic Laboratory. Both cats had granulomatous pneumonia associated with large numbers of parasite eggs and larvae, consistent with Aelurostrongylus abstrusus. Both cats also had larvae within glands in the colon that were identified morphologically as A. abstrusus first-stage larvae.
