There are increasing reports of the parasite in countries where it is not endemic. A study of the survival drug-treated immature stage (STIM) of Gnathostoma spinigerum recovered from infected patients focused on their integument surface using scanning electron microscopy (SEM). STIM displayed a specific, characteristic head bulb, with a pair of large thick equal-sized trilobulated lips in the centre. Cephalic spines had eight transverse rows on the head bulb with single-ended tips curved posteriorly. Body cuticular spines on the anterior half of the STIM were not sharp-pointed but distributed more densely, with multi-dentated-cuticular spiPloS onee0264766https://www.ebi.ac.uk/biostudies/studies/S-EPMC8903278biostudies-literatureSurvival of immature pre-adult Gnathostoma spinigerum in humans after treatment with albendazole.PMC8903278Kanjanapruthipong TThaenkham UAmpawong SWatthanakulpanich DTuentam KfalseSurvival of immature pre-adult Gnathostoma spinigerum in humans after treatment with albendazole.Human gnathostomiasis is a food-borne zoonotic helminthic infection widely reported in Latin America, Asia and Southeast Asia, particularly in Thailand.
