Stages of the parasite were detected in the gastric wall of four female dogs infected with Gnathostoma binucleatum larvae. One showed a nodule with adult worms inside, two had nodules with larvae and the other one had juvenile stages without nodules. Pre-patent period in the bitch with adult worms was 22 weeks and patent period was 14 weeks. Egg morphology and clinical profile were described. In the bitch with adult worms, a 57 x 24 mm cavernous mass was detected by ultrasonography in the stomach wall and by endoscopy the mass was detected projecting into the gastric lumen. Antibodies against larvae antigens increased (P < 0.05) after the second pi month; Western blot showed a sequential recognition of the antigens. Results provide useful data for canine gnathostomosis diagnosis.
