Climate change effects on trematodiases, with emphasis on zoonotic fascioliasis and schistosomiasis. Later, Ciurea [ 5051 ] synonymized Loossia with Metagonimus. The correlation between fish size and the intensity of infection found in this study is in agreement with studies on metacercariae of other species of trematodes POULIN, and even on Centrocestus spp. Z Infektionskr Haustiere ; The neglected zoonoses—the case for integrated control and junral.

There have been only scattered reports of outbreaks of fascioliasis in irrigated agricultural areas free from domestic animals [ 1819 tfematoda.
