Plain-English summary

An 8-year-old spayed Schnauzer was brought to the vet with a swollen belly and trouble urinating, which suggested a urinary tract infection. Tests showed unusual cysts in her abdomen, and further examination confirmed she had an infection caused by a type of tapeworm called Mesocestoides. The dog was treated with fenbendazole, a medication that successfully cleared the infection after several courses. Other treatments did not work, but fenbendazole helped in most cases, leading to recovery for this dog and others with similar infections.

Abstract

An 8-year-old spayed Schnauzer with a distended abdomen was examined because of straining to urinate and suspected urinary tract infection. Abdominal radiography revealed a ground-glass appearance, and ultrasonography revealed numerous cystic structures in the peritoneal cavity. Examination of an aspirate of abdominal fluid revealed tissues consistent with metacestodes. Tissues were definitively identified as Mesocestoides spp on the basis of polymerase chain reaction amplification of restriction fragment length polymorphisms. The dog required several courses of treatment with fenbendazole to eliminate the infection. This was 1 of 11 dogs infected with Mesocestoides metacestodes. Treatment involving the use of praziquantel and albendazole were ineffective, but fenbendazole successfully cleared Mesocestoides infections in 5 of 6 dogs.
