title: Efficacy of emodepside/toltrazuril suspension (Procox® oral suspension for dogs) against mixed experimental Isospora felis/Isospora rivolta infection in cats.
abstract: The coccidia Isospora felis and Isospora rivolta are intestinal parasites occurring worldwide in domestic cats. In young cats, they can be detected with higher prevalence.The effects of toltrazuril in the new combination product Procox(®) oral suspension for dogs containing 0.1 % emodepside and 2 % toltrazuril (0.9 mg emodepside + 18 mg toltrazuril per ml) were studied in eighteen kittens experimentally infected each with a total of 1 x 10(5) oocysts of a mixture of Isospora felis and Isospora rivolta. In the infectious material, the quantitative relation of I. felis and I. rivolta was about 1:5. Following a three-days period after infection, two groups of 6 kittens were treated during the prepatent period with either a single dose of 0.45 mg emodepside + 9 mg toltrazuril/kg body weight or 0.9 mg emodepside + 18 mg toltrazuril/kg body weight. A group of six kittens without any treatment served as a control. On day 5 post infection, the untreated kittens started the excretion of oocysts. Treatment with both toltrazuril doses significantly reduced oocyst excretion. Following the single higher dose, the reduction of oocysts of both Isospora spp. was more pronounced (96.7 % to 100 %) in comparison to the lower dose (57.2 % to 100 %). The Procox(®) application was well tolerated and no adverse events were seen with any of the applied dosages.When administered to kittens and as a single treatment during the prepatent period, Procox(®) is suitable to control the number of oocysts excreted in the faeces in case of an Isospora felis and Isospora rivolta infection.
