Aelurostrongylus is a genus of parasitic nematodes that primarily infects cats. These roundworms are commonly known as lungworms due to their habitat in the respiratory system of their hosts. The genus belongs to the family Metastrongylidae and includes several species, such as Aelurostrongylus abstrusus and Aelurostrongylus falciformis.

Life Cycle

The life cycle of Aelurostrongylus begins when infected cats pass larvae in their feces. These larvae are then ingested by intermediate hosts, such as snails or slugs. Inside the intermediate host, the larvae develop into infective stages. When a cat consumes the intermediate host, the larvae are released in the cat's digestive system and migrate to the lungs. Once in the lungs, the larvae mature into adult worms and reproduce, completing the life cycle.

Symptoms and Diagnosis

Cats infected with Aelurostrongylus may exhibit various respiratory symptoms, including coughing, wheezing, and difficulty breathing. Other signs may include weight loss, lethargy, and reduced appetite. However, some infected cats may not show any clinical signs.

To diagnose Aelurostrongylus infection, veterinarians may perform a combination of tests, including fecal examination, radiography, and bronchoscopy. Fecal examination can detect the presence of larvae or eggs in the feces, while radiography and bronchoscopy can help visualize the lung damage caused by the parasites.

Treatment and Prevention

Treatment of Aelurostrongylus infection typically involves the administration of anthelmintic drugs, such as fenbendazole or ivermectin. These medications help eliminate the adult worms and larvae from the cat's respiratory system. In severe cases, additional supportive care may be necessary to manage respiratory distress.

Prevention of Aelurostrongylus infection can be achieved by minimizing exposure to intermediate hosts, such as snails and slugs. Keeping cats indoors and avoiding contact with potentially contaminated environments can reduce the risk of infection. Regular deworming and veterinary check-ups are also important to detect and treat any infections early on.
