متن کاملParasite-induced variation in host morphology: brain-encysting trematodes in fathead minnows.
Metacercariae of the trematode Ornithodiplostomum ptychocheilus cause a conspicuous enlargement of the cranium of juvenile fathead minnows (Pimephales promelas). Minnows sampled from 2 naturally infected ponds in northern Alberta, Canada, had 12% higher and 7% wider craniums compared to fish from an adjacent, uninfected pond.

Recent discoveries of the metacercarial stage of these flukes in wild and farmed fish prompted an assessment of their risk to a community that eats raw fish. A fecal survey of 615 persons showed a trematode egg prevalence of 64.9%. Infected person...
