Presentation
The usual presentation is cutaneous gnathostomiasis, frequently preceded by a nonspecific prodrome due to larval migration. Other presentations include urogenital, visceral, ocular, and neurological gnathostomiasis [1,2]. [mdpi.com]

Prognosis
Definitive prognosis of gnathostomiasis relies mainly on the isolation of advanced-stage larvae (aL3), which is very challenging especially if the aL3 is sequestered in difficult-to-reach organs.… FREE Publisher Full TextPMC Free Full TextPMC Free PDF [unboundmedicine.com]
Etiology
The etiology of isolated optic neuritis in this patient was Gnathostoma spinigerum which was confirmed by the histopathology of the obtained parasite and the positive serologic test. [ncbi.nlm.nih.gov]
Nematodes of the genus Gnathostoma (Nematoda: Gnathostomatidae) are the etiological agents of human gnathostomiasis and may also infest dogs, cats, tigers and leopards(3). [med-chem.com]
On the third day of hospitalization, serum and stool specimens were collected and sent for testing for various parasitic etiologies, including schistosomiasis, to determine the cause of peripheral eosinophilia and liver abscess. [mdpi.com]
