In chickens, several <\/span><i><span style=\"font-weight: 400;\">Eimeria<\/span><\/i><span style=\"font-weight: 400;\"> species can cause disease. Commonly mentioned species include <\/span><i><span style=\"font-weight: 400;\">E. tenella<\/span><\/i><span style=\"font-weight: 400;\">, <\/span><i><span style=\"font-weight: 400;\">E. necatrix<\/span><\/i><span style=\"font-weight: 400;\">, <\/span><i><span style=\"font-weight: 400;\">E. acervulina<\/span><\/i><span style=\"font-weight: 400;\">, and <\/span><i><span style=\"font-weight: 400;\">E. maxima<\/span><\/i><span style=\"font-weight: 400;\">. However, accurate identification of the <\/span><i><span style=\"font-weight: 400;\">Eimeria<\/span><\/i><span style=\"font-weight: 400;\"> species requires assessment of clinical signs, lesion location, fecal testing, or more specialized techniques when needed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">After chickens ingest sporulated oocysts from the environment, the parasites invade intestinal epithelial cells and multiply in the intestinal tract. This process may damage the intestinal lining, cause bleeding, and reduce the ability to absorb nutrients and water. As a result, chickens may become dehydrated, weakened, show reduced weight gain, and become more vulnerable to other intestinal problems.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Damage to the intestinal lining may also increase the risk of digestive disorders or secondary bacterial infections under certain conditions, such as necrotic enteritis, if the flock has suitable risk factors.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The severity of damage depends on:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the number of oocysts ingested;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the <\/span><i><span style=\"font-weight: 400;\">Eimeria<\/span><\/i><span style=\"font-weight: 400;\"> species involved;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the age and immune status of the flock;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">housing conditions;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">gut health and nutrition;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the presence of other disease-causing agents.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Chickens that have not developed immunity to a specific <\/span><i><span style=\"font-weight: 400;\">Eimeria<\/span><\/i><span style=\"font-weight: 400;\"> species are usually more vulnerable than chickens that have been exposed and developed immunity.

However, diarrhea, bloody droppings, or depressed birds are not specific only to coccidiosis. Farmers should consider bird age, dropping appearance, speed of spread, housing conditions, and consult veterinary professionals when coccidiosis is suspected.<\/span><\/p>\n<h3><b>Acute Form: Rapid Progression, Abnormal Droppings, and High Loss Risk<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The acute form may be associated with <\/span><i><span style=\"font-weight: 400;\">Eimeria<\/span><\/i><span style=\"font-weight: 400;\"> species that cause severe lesions, such as <\/span><i><span style=\"font-weight: 400;\">E. tenella<\/span><\/i><span style=\"font-weight: 400;\"> in the ceca or <\/span><i><span style=\"font-weight: 400;\">E. necatrix<\/span><\/i><span style=\"font-weight: 400;\"> in the intestine.

Some birds may quickly become depressed, reduce feed intake, become dehydrated, develop pale combs, and become exhausted. However, bloody droppings are not always caused only by coccidiosis; other intestinal diseases may cause similar signs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Mortality may increase in young flocks, flocks without stable immunity, or severe cases that are not handled promptly under veterinary guidance. Beyond mortality, coccidiosis may also reduce weight gain, increase feed consumption per unit of gain, and prolong recovery after the disease episode.<\/span><\/p>\n<h3><b>Chronic and Subclinical Forms: Stunting, Slow Growth, Reduced Laying Performance, and Persistent Spread<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The chronic form often occurs when the flock is exposed to a moderate level of oocysts over time or when the disease does not cause a severe outbreak but still damages the intestinal tract.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In this form, chickens may not die quickly but often show:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">stunting;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">poor weight gain;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">poor flock uniformity;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">rough feathers;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">increased feed consumption;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">unstable droppings;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">reduced nutrient absorption.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In laying hens, chronic coccidiosis or prolonged intestinal disturbance may affect body condition, productivity, and recovery time.
