Abstract:
Crested ibis (Nipponia nippon), an endan gered native bird, was called the “precious stone” of oriental birds. N. nippon was considered a critically endangered species in the IUCN Red List of Threatened Species and a first-class national protected animal in China. The Chinese government had exerted considerable effort to protect the N. nippon population. An effective approach to increase the number of these birds was captive breeding. However, several pathogens, including parasites, could jeopardize the health of this species. The present study used the fecal flotation method to determine prevalence of intestinal parasites in fresh stool samples by wet mount smearing and iodine staining. Samples were obtained from 63 randomly selected crested ibis bred in Shaanxi Rare Wildlife Rescuing and Breeding Research Center in Zhouzhi County, Xi’an City, Shaanxi Province, China. In the 63 captive individuals, 38 were found positive for intestinal parasites (60.3%, 38/63). Of positive birds, high prevalence of Ascaris spp. (84.2%, 32/38) and Capillaria caudinflata (50.0%, 19/38) were detected. Coccidea (7.8%, 3/38), Fasciolidae (23.7%, 9/38), Blastocystis spp. (15.8%, 6/38), and Entamoeba histolytica (7.8%, 3/38) showed relatively low prevalence rates. This study focuses on the morphological identification of Ascaris spp. and C. caudinflata and their transmission in the N. nippon population. We introduce strategies to improve the breeding management of the birds, enhance their health, and stimulate population productivity. Zoo Biol. 34:80–84, 2015. © 2014 Wiley Periodicals Inc.
