 Abstract: The red panda (Ailurus fulgens) is a herbivorous carnivore. It is the only member of the familyAiluridae in the superfamily Musteloidea, closely related to the raccoons (Procyonidae) andweasels (Mustelidae). In the wild the red panda is found in the Himalaya of Nepal, Tibet, Bhutan,India, Myanmar, Yunnan and Sichuan provinces of China and the Meghalaya plateau of India. Thered panda has been kept and bred in European zoos since 1869.There are several reports of metastrongyloid parasites in the red panda. In a survey of NorthAmerican zoos in 1982 lungworms were detected in all zoos that used the Baermann method forcoprological examinations. In Europe Angiostrongylus vasorum and Crenosoma striatum have beendiagnosed in red pandas.Angiostrongylus vasorum and Angiostrongylus cantonensis are metastrongyloid parasites whichinhabit the pulmonary arteries and right ventricle of the heart of their definitive hosts. They both usemollusks as intermediary host. Angiostrongylus vasorum develop into adult worms in themesenteric lymph nodes of the definitive host, while A. cantonensis undergo development in thebrain of its definitive host. First stage larvae are shed in the feces of the definitive host and can bedetected with the Baermann method. Aelurostrongylus falciformis, Crenosoma vulpis, C. striatumand Crenosoma melesi are all metastrongyloid parasites which inhabit the bronchial tree of itsdefinitive host. Terrestrial mollusks serve as intermediate hosts and development into adult wormstakes places in the lungs of their definitive hosts. Using the Baermann method, first stage larvae ofthese parasites can be detected in the feces of infected definitive hosts.A study of the prevalence of metastrongyloid parasites in the red panda population in zoos withinthe European Association of Zoos and Aquariums was conducted during the winter of 2008/2009. Atotal of 113 red pandas from 53 zoos were included in the study. An overall prevalence formetastrongyloid parasites of 34.5 % (39/113) was found. Three categories of metastrongyloid firststage larvae were found. Angiostrongylus vasorum was diagnosed in 2.65 % (3/113), Crenosomaspp. was diagnosed in 4.42 % (5/113) and an unidentified metastrongyloid parasite was diagnosedin 27.4 % (31/113) of the animals. The isolated first stage larvae of each of the parasite categorieswere morphologically described. The significance of the parasitological findings in the presentstudy was unclear and further investigations are warranted as well as further description of theunidentified metastrongyloid found. Experimental infections of laboratory animals to describe thelife cycle and adult morphology of the parasite as well as genetic sequencing are suggested.
