Table 1 Design of a study aimed at determining the effectiveness of imidacloprid/flumethrin collars in preventing Dipylidium caninum infection in cats repeatedly infested with infected fleas

From: Prophylactic treatment of flea-infested cats with an imidacloprid/flumethrin collar to forestall infection with Dipylidium caninum
