title: Diagnosis and treatment of peritonitis caused by a larval cestode Mesocestoides spp., in a dog.
abstract: Infection of the peritoneal cavity with cestode larvae, presumptively diagnosed as tetrathyridia of the genus Mesocestoides, was found by exploratory celiotomy in a dog with clinical signs consisting of episodic anorexia, vomiting, and depression. Lymphopenia and hypoalbuminemia were associated clinicopathologic abnormalities. Dystrophic calcification and midline duodenal displacement were found on abdominal radiographs. Therapy with mebendazole was instituted after recurrence of the initial episodic clinical signs postoperatively. Daily use of mebendazole for intermittent periods of up to 3 months led to remission of gastrointestinal signs for 30 months. However, 17 months after the initial diagnosis, infection of the vaginal tunic of the testicle with similar cestode larvae necessitated castration and removal of the vaginal tunic to the inguinal ring. Mebendazole therapy was reinstituted and continued for 31/2 months postoperatively. The dog was free of clinical signs of infection during and for the 16 months since this period of treatment.
