Abstract: The commercial poultry sector is one of the most important segments of global trade and production. Coccidiosis is one of the most common and economically important diseases in the poultry industry around the world. In this report broiler aged 20 days were affected by coccidiosis and it was brought in Upazila Livestock Office and Veterinary Hospital (ULOVH), Chakaria, Cox’s Bazar on 15th February, 2021. Based on clinical history, clinical signs, gross lesions and microscopic findings the disease was diagnosed. The clinical signs were disordered feathers, blood stained whitish to brownish diarrhoea, loss of appetite, and depression. The gross lesions were distended caecal and intestinal segments with frank blood, mucus and tissue debris, hemorrhages in the caecal wall and intestine and clotted blood in the lumen of caeca. There was also found pseudomembrane in the intestine. In coproscopy, sporulated oocyst of Eimeria was found under microscope. A secondary bacterial infection of Clostridium perfringens causing Necrotic Enteritis (NE) was also found in this case. Visits to the farm revealed inadequate hygiene and ventilation standards. To prevent coccidiosis good hygienic conditions should be maintained in the farm, damp and wet litter must be avoided and good ventilation should be provided. Avoiding overcrowding and making good use of a prophylactic anti-coccidial shuttle program are also essential to prevent the threat of coccidiosis.
