“…The larvae migrate to the skin and subcutaneous tissue causing the typical migratory swellings (cutaneous disease in the majority of cases), occasionally the larvae may penetrate into deeper tissues (viscera, the lungs, eyes, ears, gastrointestinal and genitourinary systems and rarely, but often fatally, the Central Nervous System (Herman and Chiodini, 2009). Gnathostoma spinigerum infections have been recognised as an emerging cause of eosinophilic encephalomeningitis (Diaz, 2010) and ocular infections (Lenka et al, 2016). Cutaneous gnathostomosis developes within an incubation time of weeks up to 12 months as larva migrans in cutaneous nodules.…”

For a long time, wildlife carnivores have been disregarded for their potential in transmitting zoonotic nematodes. However, human activities and politics (e.g., fragmentation of the environment, land use, recycling in urban settings) have consistently favoured the encroachment of urban areas upon wild environments, ultimately causing alteration of many ecosystems with changes in the composition of the wild fauna and destruction of boundaries between domestic and wild environments. Therefore, the exchange of parasites from wild to domestic carnivores and vice versa have enhanced the public health relevance of wild carnivores and their potential impact in the epidemiology of many zoonotic parasitic diseases. The risk of transmission of zoonotic nematodes from wild carnivores to humans via food, water and soil (e.g., genera Ancylostoma , Baylisascaris , Capillaria , Uncinaria , Strongyloides , Toxocara , Trichinella ) or arthropod vectors (e.g., genera Dirofilaria spp., Onchocerca spp., Thelazia spp.) and the emergence, re-emergence or the decreasing trend of selected infections is herein discussed. In addition, the reasons for limited scientific information about some parasites of zoonotic concern have been examined. A correct compromise between conservation of wild carnivores and risk of introduction and spreading of parasites of public health concern is discussed in order to adequately manage the risk of zoonotic nematodes of wild carnivores in line with the ‘One Health’ approach.

“…In India also, sporadic cases of gnathostomiasis in both animals and man have been reported. G. spinigerum was reported from cats, dogs and wild felines from different regions including the Northeast (Baruah and Gogoi, 1989;Deka et al, 1995;Borthakur and Mukherjee, 2011;Islam et al, 2014;Lenka et al, 2016) [7,8,9,10,11] . Additionally, G. hispidum and G. doloresi were also reported in domestic pigs from the Northeast and Eastern region ~ 102 ~ (Maplestone, 1930;Yadav and Tandon, 1989;; NEHU 2021) [12.…”

The present communication deals with morphological identification of a parasite specimen sent from a private eye hospital at Guwahati, Assam after its extraction alive from the aqueous humor in the right eye of a non-tribal rural woman from Assam. The parasite 3 mm X 0.3 mm in size, characterized by the presence of a distinct anterior head bulb armed with four rows of hooklets numbering less than 40 per row and spination along the transverse striations present throughout the body was identified as the third stage larva of a pig gnathostome, Gnathostoma doloresi. Interview based investigation to ascertain the source of G. doloresi infection reported here for the first time in the 32 year old non-vegetarian house wife having no history of raw fish consumption revealed water used for domestic purpose from a pond adjacent to domestic pig pastured swampy area and the fresh water fishes as the possible sources of infection which might have occurred by accidental ingestion of infected cyclops present in pond water or by direct skin penetration of the larval stage of the parasite during descaling and evisceration of infected fishes prepared for cooking and consumption.
