“…In context of India, the focal transmission of paragonimiasis has been documented in north-eastern states of the country, such as Arunachal Pradesh, Manipur and Nagaland (WHO 2009). Several species of Paragonimus have been reported to occur in the commonly edible crab species prevailing in the mountainous ranges of Northeast India (Singh 2002(Singh , 2003Narain et al 2003;Singh et al 2006Singh et al , 2007Singh et al , 2009Tandon et al 2007;Devi et al 2010). The regions, where crabs are commonly consumed as part of their traditional cuisine are suspected foci for human infection (Tandon et al 2007).…”

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.

“…The first ever case of paragonimiasis was reported by Kerbert from the lungs of a Bengal tiger more than a century ago. 1 In India the first case was reported from Manipur in 1982. Subsequently, endemic foci of Paragonimus westermani and Paragonimus heterotremus have been reported from Manipur, Nagaland, Arunachal Pradesh, Bengal and Assam.…”

Infection caused by the lung fluke is endemic in north eastern parts of India. Paragonimus westermani and Paragonimus heterotremus are known to be endemic in eastern Indian states of Manipur and Nagaland. The infection is related to eating habits of the locals and is acquired by ingestion of raw, inadequately cooked crabs or crayfish containing encysted metacercariae which act as second intermediate hosts during the life cycle of the lung fluke. Diagnosis is generally delayed due to lack of suspicion and presentation similar to tuberculosis which is endemic in the population. We report pleuropulmonary paragonimiasis in a soldier from eastern India who presented with chest pain, haemoptysis, and eosinophilia. He gave history of consumption of raw crabs while on leave at his native village in Nagaland. Ova morphologically resembling Paragonimus heterotremus were detected in sputum and bronchoalveolar lavage specimen. Symptoms resolved with praziquantel treatment.
