Efficacy of some anticoccidial drugs for treating coccidial enteritis of the common carp caused by Goussia carpelli (Apicomplexa: Eimeriidae).
In this study, nine anticoccidial drugs commonly used in poultry were tested for efficacy for the prevention and treatment of Goussia carpelli (Apicomplexa) infection in common carp (Cyprinus carpio L.). To establish experimental infection with G. carpelli, paratenic host oligochaetes of the genera Tubifex and Limnodrilus were infected with oocysts, and laboratory-cultured parasite-free common carp fingerlings were infected by feeding to them oligochaetes containing sporozoites. The anticoccidial drugs (amprolium, narasin, maduramicin, salinomycin Na, lasalocid Na, diclazuril, robenidine HCl, monensin Na and toltrazuril), mixed in the food of the fish in a dose of 200 mg/kg, were fed for 12 days. Common carp fingerlings fed diclazuril, lasalocid, robenidine HCl or maduramicin and killed on day 14 after exposure were free from infection, while other groups treated with amprolium, toltrazuril, monensin Na, narasin or salinomycin Na harboured oocysts in the mucus and epithelium of the gut.
