    Area of Science:

    • Medical Parasitology
    • Molecular Diagnostics
    • Ophthalmology

    Background:

    • Gnathostomiasis is a severe parasitic infection caused by Gnathostoma spinigerum nematodes.
    • Ocular involvement can lead to significant vision impairment.
    • Autochthonous cases are infrequently reported in many regions, including Africa.

    Purpose of the Study:

    • To report the first autochthonous case of human gnathostomiasis in Madagascar.
    • To confirm the causative agent, Gnathostoma spinigerum, using molecular methods.
    • To raise awareness among clinicians regarding this potential parasitosis in endemic areas.

    Main Methods:

    • Molecular identification of the nematode species from patient-derived samples.
    • Clinical examination and ophthalmological assessment of the affected individual.
    • Review of relevant literature on gnathostomiasis in Africa.

    Main Results:

    • Molecular analysis confirmed the presence of Gnathostoma spinigerum.
    • The patient presented with severe ocular gnathostomiasis, resulting in vision loss in the left eye.
    • This case represents a significant finding for the epidemiology of gnathostomiasis in Madagascar.

    Conclusions:

    • Molecular tools are crucial for accurate diagnosis of gnathostomiasis.
    • Ocular gnathostomiasis is a serious condition requiring prompt recognition.
    • Clinicians in Madagascar and other African nations should consider gnathostomiasis in patients with relevant symptoms.
