Capillaria plica (syn. Pearsonema plica) is a nematode parasite of the urinary tract of canids, felids and mustelids, which can cause cystitis, pollakiuria, dysuria and hematuria. An eight-month-old female crossbred dog from Switzerland presented a six-month history of frequent urination. During the first clinical examination, C. plica eggs were detected in the urine sediment. Three series of treatments with fenbendazole (50 mg/kg body weight [BW]/day, orally) for 10 days each, three single day treatments with moxidectin-imidacloprid (spot-on) and one single administration of ivermectin (0.2 mg/kg BW subcutaneously) were performed within an eight-month period. None of those treatments succeeded in eliminating the C. plica infection or in resolving the clinical signs. An endoscopic examination of the urine bladder still revealed numerous adult viable C. plica worms attached to the bladder mucosa. A two-day treatment with levamisole (7.5 mg/kg BW/day intramuscularly) was subsequently performed. An endoscopic control of the urine bladder two days after this treatment and a urine analysis after two weeks confirmed the elimination of the parasites. The clinical signs disappeared within one month. Levamisole was shown to be effective against C. plica infection in a dog, whereas previous treatments with fenbendazole, moxidectin and ivermectin had failed.
