“…The channid fishes are reported to harbour metacercariae of several trematodes, e.g. Atrophecaecum hindusthanensis, Clinostomum sp., E. heterostomum, Diplostomulum cerebralis, Neascus gussevi, Metaclinostomum srivastavi and Tetracotyl szidati, to name a few (Chakrabarti 1974;Jhansilakshmibai and Madhavi 1997;Thapa et al 2008;Vankara et al 2011). Several species of Euclinostomum have been reported from India; these include E. indicum and E. heptacaecum from C. punctatus and E. channi from C. marulius (Bhalerao 1942;Jaiswal 1957).…”

A pioneering amount of literature is available on metacercariae of various digenetic trematodes from fishes all over the world (Malek and Mobedi 2001;Arafa et al 2005;SilvaSouza and Ludwig 2005;Vianna et al 2005;Rim et al 2008;Han et al 2008;Sohn 2009;Skov et al 2009;Sohn et al 2009;Gustinelli et al 2010;Thuy et al 2010;Gholami et al 2011), including that from India (Kumari 1994;Jhansilakshmibai and Madhavi 1997;Singh et al 2003;Vankara et al 2011;Shareef and Abidi 2012).…”

Food-borne trematode infections, which are mainly transmitted through consumption of inadequately cooked or raw fish and crabs, affect a large section of population, particularly in Southeast Asian countries, thus eliciting a remarkable morbidity and causing serious damage to health. In India, centering in several mountainous regions of the Northeast, the natives have the habit of consuming such fish or crabs that still sustain viable infective larval stage (metacercaria) of trematode flukes in their muscle tissue. The present study was undertaken to ascertain the spectrum of metacercarial diversity in commonly edible freshwater fishes and crab species in the northeastern state of Manipur and to adjudge their zoonotic potential, if any. Commonly edible fishes belonging to 15 species from 12 localities and crabs belonging to 2 species from 11 localities across Manipur state were surveyed for the purpose. The study revealed that 3 species of fishes (Channa punctatus, C. straitus and Wallago attu) harboured 4 different types of metacercariae belonging to 4 trematode families-Euclinostomum heterostomum (Clinostomidae); Lophosicyadiplostomum sp. and Posthodiplostomum sp. (Diplostomidae); and Polylekithum sp. (Allocreadiidae) in addition to adult flukes of Isoparorchis hypselobagri (Isoparorchiidae). Among these, metacercariae of Posthodiplostomum showed the highest prevalence (2.33 %) though a low abundance, while for other species the prevalence ranged between 0.25 and 1.19 %. The crab species (Barythelphusa lugubris masoniana and Potamiscus manipuriensis) were found infected with 4 different types of metacercariae representing the genera Paragonimus (Troglotrematidae) and Microphallus (Microphallidae). The paragonimids showed a higher rate of occurrence (*4-25 %) compared to microphallids (*15 %). The crustaceans surveyed emerged as prospective intermediate hosts for lungflukes. Identifying the potent vectors for zoonotic parasites helps in control measures towards their transmission to higher mammals.

Histo-architectural alterations induced by Euclinostomum heterostomum (metacercariae) infected liver of Channa punctata (Bloch)

Present investigation was carried out to study the effect of digenetic trematode, Euclinostomum heretostomum on the histo-architecture of liver of Channa punctata. In case of mild infection, the metacercariae were found attached to the external surface of hepatic tissue. While in case of acute or chronic infection, the encysted metacercariae of Euclinostomum heterostomum were found deeply embedded in the entire hepatic tissue due to which liver appeared thin, compressed and pale with yellowishblack nodules of encysted metacercariae. A space occupying cavity is created by the metacercarial cysts due to which tissue appeared in the form of lumps. Histo-architectural alterations induced by parasite included degeneration, compression and loosening of hepatic tissue with enucleated and deshaped hepatocytes.

“…Usually digenean metacercariae which occur in the liver and other visceral organs cause severe melanosis of the liver and visceral fibrosis (Mitchell et al 1983). Metacercaria of E. heterostomum have been studied by Bhalerao (1942), Srivastava (1950), Jaiswal (1957), Gupta and Agarwal (1983), Jhansilakshmibai and Madhavi (1997). Metacercariae inhabits every major organs of the host body like liver, heart, gills, body cavity etc.…”

Pathological effect on naturally infected kidneys of freshwater murrels by Euclinostomum heterostomum metacercariae

Present investigation was carried out to study the histo-pathological alterations induced by metacercariae of digenetic trematode, Euclinostomum heretostomum on the kidney of Channa striatus and Channa marulius in natural condition. Histo-architectural alterations induced by parasite included reduced size of glomeruli, severe degeneration and necrosis of haemopoietic tissue and tubule cells with hypertrophied nuclei in C. striatus. Whereas, infected kidney of C. marulius exhibited the development of several melano-macrophage centers, hypertrophied nuclei of tubule cells and detached epithelial cells of renal tubules. Therefore an attempt has been made to record the first naturally occurring pathogenicity of E. heterostomum in kidney of freshwater murrels.
