Abstract

Abstract: Objective To understand the infection status of gastrointestinal parasites in captive-bred non-human primates (Macaca mulatta and Macaca fascicularis) in Guangxi, and provide basis for prevention and control strategies. Methods The monkeys were divided into three groups, the growth group, the breeding group, and the quarantine group. Totally 784 fresh feces samples from M. mulatta and M.fascicularis were collected at six monkey shelters in Guangxi, during 2008~2012. The direct smear method (DS), saturation salt solution float method (SSF) and formaldehyde-ether precipitation method (FEP) were used for fecal parasite examination under the microscope. Results The total infection rate was 72.4% among 784 sample. Five protozoan species Ameoba, Trichomonas sp., Giardia sp., Balantidium coli and Coccidia), five species of nematodes(Trichuris sp., Streptopharagus sp., Physaloptera sp., Oesophagostmum sp. and Strongyloides sp.), two species of cestodas (Hymenolepis sp. and Bertiella studeri), one speice of trematoda and one speice of arthropod were identified. The gastrointestinal parasites infection of the growth group was possessed of the fewest among three groups, while the quarantine group was the largest. Relatively higher prevalence of protozoan was observed in both the growth monkey group and the breeding group, and the highest infection rate was found in both Amoeba and B.coli. Conclusions The results suggest that the protozoans with simple lifecycle and the soil-transmitted nematodes which are difficult to kill by antihelmintic products nowadays, have become the major parasitic species that does serious harm to the captive-bred monkeys for experiment used in Guangxi. Herein, the infestation status could provide reference for prevention and controling strategies on parasitic disease of monkeys. Some species identified from this study have been considered as the pathogens of zoonose, which will have important public sanitation significances of countermeasure on disease spread between humans and captive-bred monkeys.
