Experimental infection of Gnathostoma binucleatum in Canis familiaris from the municipality of Tepic in Nayarit, Mexico. Abanico vet [online]. 2018, vol.8, n.1, pp.53-58.

Gnathostoma binucleatum is the etiological agent of animal and human gnathostomiasis in the Nayarit state. In four infected female dogs, parasite phases were found in the stomach. Only one female dog eliminated eggs and adult parasite phases in feces. In this dog, the prepatent period lasted 22 weeks and the patency period 14 weeks. Necropsy results showed a copiously vascularized 10-cm diameter fibrous nodule lodged in the greater curvature of the stomach. Two female dogs that did not eliminate any eggs showed 1-2 cm diameter nodules on the gastric wall with 5 juvenile phases in each. One female dog that did not eliminate any eggs and exhibited no gastric nodules showed juvenile parasites on the gastric wall. New data on the pathological and parasitological aspects of canine gnathostomiasis are presented.

Palabras llave : Gnathostoma binucleatum; nodules; infected dogs.
