Angiostrongylus vasorum in a Red Panda (Ailurus fulgens): Clinical Diagnostic Trial and Treatment Protocol.

Abstract

The literature refers that Angiostrongylus vasorum should always be considered in the differential diagnosis of respiratory diseases in captive red panda (Ailurus fulgens) from endemic areas, and the importance of undertaking a careful diagnostic process and timely medical treatment are crucial when the disease is suspected. The authors think that the description of this clinical case can help other colleagues in the deworming, clinical and anesthesiologic management of infected subjects. A red panda was referred to the Veterinary Teaching Hospital of the University of Milan in Lodi, due to a diagnosis of A. vasorum formulated in May 2015. The diagnosis was made after the detection of both first-stage larvae by Baermann technique and antigens by serological rapid in-clinic assay. In addition, haemochromocytometric and blood chemistry tests, echocardiography and a CT examination were carried out. The subject was successfully treated by oral administration of milbemycin oxime and praziquantel (Milbemax, Novartis, Italy), respectively, at the weekly dose of 12.5mg/subject and 125mg/subject for three consecutive weeks, alternated with 20days of suspension. Treatment continued with the same scheme until clinical examination carried out in Lodi in December 2018. The follow-up of the described clinical case demonstrates how appropriate management of the infection and the subsequent prophylaxis can correctly eliminate the parasite, thus avoiding the spread of the nematode and the onset of severe and lethal lung forms as described in the literature.
