Toxoplasma gondii-like oocysts were detected in 4% of cat feces using light microscopy in Kunming, China. Amplicon was generated from these oocysts using a T. gondii- but not Hammondia hammondi-specific primer set. Cat and KM mouse were susceptible t

Cattle are intermediate hosts for 2 zoonotic species of Sarcocystis, Sarcocystis hominis and Sarcocystis heydorni. Here we report S. heydorni from cattle for the first time in China. Sarcocysts of S. heydorni were found in muscle from 173 of 1,630 (1

Allopodocotyle chiliticorum n. sp. is described from the intestines of redlip shiners (Notropis chiliticus) from Basin Creek, North Carolina. The new species is characterized by circumcecal vitelline fields that are not confluent in the post-testicul

The performance of 2 nonparametric estimators of species richness, the bootstrap (S(B)) and kth-order jackknife (S(Jk)), are compared using simulated parasite communities. The parameters of the simulation match those of an earlier comparison that fav

In response to confusion regarding the taxonomy of halipegines inhabiting North American amphibians, the reproductive structures of the hemiurid Halipegus occidualis are described from adult worms reared from cercariae shed by Helisoma anceps from Ch

The transmission dynamics of the trematode Halipegus occidualis in its definitive host, Rana clamitans, have been examined over a 5-yr period in a North Carolina pond. The breeding season of green frogs coincides with the period of worm recruitment,

Interactions between metacercariae of Halipegus occidualis and ostracod second intermediate hosts (Cypridopsis sp.) were examined over 5 wk using female ostracods exposed to 4 cercariocysts each and maintained in isolation. Control ostracods were sub

The temporal and spatial dynamics of the recruitment of Halipegus occidualis by the green frog, Rana clamitans, suggest that infections are acquired through predation on odonates, which become infected by feeding on ostracods. Discrepancies in the li

Inhibition of snail reproductive activity by larval trematodes often results in increased growth of the snail, termed gigantism, during which the snail is hypothesized to allocate excess energy normally used for reproduction to somatic growth. Using

Trematode community structure was examined in the pulmonate snail Physa gyrina over a 12-mo period. A total of 1,181 snails was collected from Charlie's Pond, North Carolina, and was found to be parasitized by 6 trematode species. Infracommunities we
