A total of 549 suspected chickens of having blackhead disease at Phu Binh district, Thai Nguyen province were dissected for finding Histomonas meleagridis protozoa. As a result there were 203 chickens infected with the Histomonas meleagridis protozoa, accounting for 36.98%. In which, the infection rate of chicken raising in Tan Kim commune was highest (43.59%) and the lowest infection rate was in Ban Dat commune (22.45%). Chickens of all ages were infected with H. meleagridis protozoa, but the prevalence was highest in chickens at age group from 1 to 3 months old (58.52%). Chickens raised in summer season suffered with the higher prevalence of H. meleagridis in comparison with chickens raised in other seasons. The chickens raised by semi-grazing method had the highest prevalence (46.05%), followed by free grazing method (37.28%) and the lowest was chickens rearing in captive method (24.85%). The treatment efficacy for blackhead disease in chickens of the two regimens reached 90 to 93.33%.Mổ khám 549 con gà nghi mắc bệnh đầu đen tại huyện Phú Bình, tỉnh Thái Nguyên đã phát hiện 203 gà nhiễm trùng đơn bào Histomonas meleagridis (H. meleagridis), tỷ lệ gà nhiễm bệnh chiếm 36,98%.
