The infection patterns of parasites are often tied to host behavior. Although most studies have investigated definitive hosts and their parasites, intermediate host behavior may play a role in shaping the distribution and accumulation of parasites, particularly the larval stages. In an attempt to answer this question, more than 4,500 pulmonate snails were collected from 11 states in the mid-Atlantic and Midwestern United States in the summer of 2012. These snails were necropsied and echinostome metecercariae were commonly observed infecting the snails as 2nd intermediate hosts (20.0%). The snails included species of 3 genera with distinct differences in the infection patterns of Echinostoma spp. metacercariae among them. Physa spp. (comprising of P. acuta and P. gyrina) snails exhibited a significantly higher prevalence of infection (23.5%) than both Lymnaea columella (11.6%) and Helisoma spp. (comprising of H. anceps and H. trivolvis) (14.2%; P < 0.05), with no difference in prevalence observed between the latter 2 genera (P > 0.05). The intensity of metacercariae within the snail hosts was significantly different between the 3 genera (P < 0.05), with L. columella having the highest intensity (24.3 ± 5.6), followed by Physa spp. (15.2 ± 1.5) and Helisoma spp. (5.0 ± 0.9). Differences in prevalence and intensity were also observed when the different snail families co-habited the same body of water. The disparities in infection patterns are likely due to distinct differences in the behavioral and feeding ecology of the snail hosts.

Echinostomatidae (Trematoda) is the largest family within the class Trematoda. Members of this family have been studied for many years in relation to their utility as basic research models in biodiversity and systematics and also as experimental models in parasitology since they offer many advantages. Echinostomes have contributed significantly to numerous developments in many areas studied by parasitologists and experimental biologists. In this review, we examine the history of the echinostomebased studies from the beginnings to the present. For this purpose, we have divided the history of echinostomes into four periods (i.e. 18th and 19th centuries, first half of the 20th century, second half of the 20th century and the late 20th and 21th century) according to the types of studies performed in each of them. Moreover, we also briefly review the history of echinostome infections in humans.
