Abstract: One hundred and fifty-three fecal samples of pet hamsters（Mesocricetus auratus, Phodopus sungorus, P. campbelli and P. roborovskii） were collected from a pet-market in Zhengzhou, and examined by Sheather?蒺s sugar flotation, modified acid-fast staining and Lugol?蒺s iodine-solution staining. The prevalence of parasites was 70.7%（41/58）, 96.7%（59/61）, 83.9%（26/31）, and 100%（3/3）respectively, with an overall prevalence of 84.3%. Eggs, cysts or oocysts of Cryptosporidium sp.（15.0%）, Giardia sp.（22.2%）, coccidian（2.0%）, Hymenolepis nana（31.4%）, Hymenolepis diminuta（25.5%）, Syphacia spp.（41.8％）, Aspiculuris tetraptera（7.2%） and undetermined Trichurata nematode（18.3%） were found from the samples. The results suggest that pet hamsters may be infected and transmit several zoonotic parasites.
