Gnathostoma spinigerum is a parasitic nematode that causes gnathostomiasis in humans, also known as its clinical manifestations are creeping eruption, larva migrans, Yangtze edema, Choko-Fuschu Tua chid and wandering swelling. Gnathostomiasis in animals can be serious, and even fatal. The first described case of gnathostomiasis was in a young tiger that died in the London Zoo in 1835. The larval nematode is acquired by eating raw or undercooked fish and meat.

  • Gnathostoma spinigerum is a parasitic nematode that causes gnathostomiasis in humans, also known as its clinical manifestations are creeping eruption, larva migrans, Yangtze edema, Choko-Fuschu Tua chid and wandering swelling. Gnathostomiasis in animals can be serious, and even fatal. The first described case of gnathostomiasis was in a young tiger that died in the London Zoo in 1835. The larval nematode is acquired by eating raw or undercooked fish and meat. G. spinigerum has a multi-host life history. The eggs hatch in fresh water and the larvae are eaten by water fleas of the genus Cyclops. The water fleas are in turn eaten by small fish. Eventually, the larvae end up in the stomachs of carnivores, usually cats and dogs. The larva bores through the stomach wall and migrates around in the host's body for about three months before returning to the stomach and attaching itself in the gastric mucosa. It then takes another six months to mature. The eggs are carried in the host's feces, and if they reach fresh water the cycle begins again. As humans are not a normal host for the larva, they do not mature in humans, but can cause various degrees of damage, depending on where the larva wanders in the body. (en)
  • Gnathostoma spinigerum est une espèce de nématodes parasites qui cause chez l'homme la gnathostomose. Ce parasite a un cycle complexe qui comprend plusieurs hôtes. Les œufs éclosent en eau douce et les larves sont ingérées par des puces d'eau du genre Cyclops. Celles-ci sont ensuite ingérées par des petits poissons, et le parasite termine finalement dans l'estomac d'un carnivore, généralement chien ou chat. La larve migre alors dans le corps de l'animal après avoir traversé la muqueuse durant environ trois mois avant de revenir dans la paroi de l'estomac, où elle va atteindre sa maturité et pondre des œufs qui iront dans les fèces, et éventuellement dans de l'eau afin que le cycle recommence.
