Biological control of zoonosis in zoological parks: trichurosis and capillarosis
Abstract
Keeping of wild animals in fenced plots with vegetation in Zoological Parks results beneficial, but also favors the continued presence of some helminths. In this study the usefulness of ovicidal fungi spores of Mucor circinelloides and Trichoderma sp has been tested on feces of dromedaries (Camelus dromedarius) and wapiti (Cervus canadensis) passing eggs Trichuris sp. and Capillaria sp., respectively, by feces. The percentage of viable eggs of Capillaria sp. was reduced in the presence of M. circinelloides to 19% at 30 days, and 41% with Trichoderma sp. Addition of spores of M. circinelloides to feces containing eggs of Trichuris sp. decreased their viability to 50% at 30 days, as with Trichoderma sp. It is concluded that the distribution of spores in feces of parasitized animals significantly reduces the risk of infection in animals and people.Downloads
