Investigation on the Prevalence of Intestinal Parasites in Captive Wildlife in Zoos of Henan Province
To investigate the prevalence of intestinal parasites in captive wildlife in zoos of Henan province,513 fecal samples from 41 animal species were collected and examined by centrifugal precipitation,Lugoul's iodine staining and saturated sucrose floatation.The results showed overall infection rate of intestinal parasites at 33.5%(172/513)and detection of 8 kinds of eggs,oocysts or cysts in captive wildlife.The main parasite species were Coccidia,Amoeba,Ascaris and Strongylidae,which were 18.3%(94/513),6.8%(35/513),6.4%(33/513)and 6.2%(32/513),respectively.The infection rates of intestinal parasites were 29.4%(103/350)in herbivores,46.2%(12/26)in omnivores,29.5%(18/61)in carnivores and 51.3%(39/76)in birds,respectively.The infection intensity of eggs,oocysts or cysts were found much higher in fecal samples from Pavo cristatus,Cervus nippon and Macaca mulatta.This study revealed the prevalence of intestinal parasites in captive wildlife in zoos of Henan province,suggesting that effective measures should be taken to strengthen the prevention and control of parasitic infections.
