Effect of infection by the metacercarial
trematode Renicola roscovita on growth in intertidal blue mussel Mytilus edulis.
Geographical variation in metacercarial
infection levels in marine invertebrate hosts: parasite species character versus local factors.
In fact, known peaks in metacercarial
encystment match this seasonal variation in forage availability and feeding behavior (Lepitzki 1998).
cysts were collected from the abdominal tissues that cover the insides of the dorsal carapace and hepatopancreas.
distribution of Centrocestus formosanus among fish hosts in the Guadalupe River drainage of Texas.
Specific identification was confirmed by morphologic appearance of adult worms recovered from hamsters (Figure) and PCR and sequence analysis of the partial metacercarial
CO1 gene, amplified by CO1-OV-Hap-F&R primers (7).
In addition, some studies showed an increase in the prevalence and mean intensity of metacercarial
infection among larger snails (Morley, Lewis & Adam, 2004; Flores, Semenas & Veleizan, 2010).
Clarias gariepinus plays a notably important role in the life cycles of digenean parasites in the Okavango Delta, as it acts as a definitive host for adults of four species, and as a second intermediate host to two metacercarial
Fascioliasis develops by the taking in of metacercarial
cysts through consumption of aquatic plants (watercress in particular), or of contaminated water like in our case (6).
In Pakistan people do not use raw or undercooked fish, so do not get infection with metacercarial
trematodes but in some countries like Thailand, Korea, Germany, China and Canada, etc.
Diplostomum spathaceum metacercarial
infection and colour change in salmonid fish.
Therefore, in the present study, the diplostomid metacercarial
infection in the eyes of several freshwater fish species in the Almus Dam Lake on Yesilirmak river, Turkey was examined.
