1. Introduction:  Coccidiosis is a protozoal infection that is caused by different protozoans belonging to the Eimeria genus . It is arguably the most important disease to the poultry industry, and its economic impact is huge. Unlike a viral infection, coccidiosis infects the lining of the intestine, resulting in malabsorption, poor feed conversion, and even death from bloody diarrhea Coccidosis in poultry 3. Life Cycle of Eimeria To understand the life cycle is essential to control it. Eimeria has an Exogenous Phase Outside the Bird and an Endogenous Phase Inside the Bird. Sporulation (Environmental Phase):  The life cycle of Eimeria begins when an infected bird sheds unsporulated oocysts with feces. These need specific conditions to sporulate. These are warmth (25-30°C), moisture (humidity of litter >25%), and oxygen. After 24 to 48 hours, they are now infectious. The most important factor is the litter. Wet litter is the biggest enemy in the poultry house. Ingestion an...

 Introduction Arguably, coccidiosis is the most economically important parasitic disease in the poultry industry worldwide. It is caused by protozoa belonging to the Eimeria group and attacks the intestinal tract. It results in malabsorption, weight loss, and high mortality rates. For a DVM professional, coccidiosis control is not just about treatment; it’s all about " Gut Integrity . The Pathogen: Eimeria Species Different species of Eimeria affect different parts of the avian gut: ​ E. tenella : Affects the ceca (causing bloody droppings ). ​E. necatrix: Affects the mid-small intestine. ​E. acervulina: Affects the upper small intestine. Clinical Manifestations Farmers often miss the early signs, but a clinical eye should look for: ​Bloody Droppings :  The most common sign of E. tenella. ​Ruffled Feathers & Pallor:  Birds look "hunched up" and pale due to blood loss (anemia). ​Poor FCR (Feed Conversion Ratio) :  Birds eat but do not gain weight because their ...
