Using single oocyst infected techniques, three strains of Eimeria tenella, PT0705, FQ0709 and LJ0711, were obtained from classically symptomic coccidian chicken in Putian, Fuqing and Lianjiang Couties, Fujian Province. In order to compare their toxicity against chicken, healthy chicken of 14th-day and 21th-day were artificially infected with 1×104, 5×104 and 10×104 coccidian oocysts of PT0705, FQ0709 and LJ0711, respectively. The results showed that the strain PT0705 was the most toxic to tested chicken based on the clinical symptom, survival rate, weight increment and lesion grade investigations.
