Coccidiosis is a disease that is caused by protozoan parasites of the genus Eimeria, developing within the intestine of most domestic and wild animals and birds. The disease is distributed worldwide and primarily affects young animals that are raised under various management systems with the infections more severe and more frequent in animals that are raised in intensive systems. Coccidiosis is responsible for major losses due to mortality and primarily to the poor performance of sub clinically infected animals which costs the livestock industry many millions of dollars. Diagnosis and genetic characterization of different species of Eimeria are central to the prevention and control of coccidiosis. This is particularly important with regard to the appearance of a widespread anticoccidial resistance of Eimeria species. In fact Eimeria are very effective parasites, one of the main reasons coccidiosis is still a major problem, is the difficult diagnosis. The classical parasitological methods of diagnosis are labor intensive and therefore costly. Different diagnostic tools such as fecal flotation techniques, morphological identification, molecular biology, biochemistry, cell biology and immunology have been used to diagnose coccidiosis. These methods have generally had major limitations in the specific diagnosis of coccidiosis and identification of Eimeria species. The traditional approaches are unreliable, particularly when multiple species of Eimeria simultaneously infect a single host and there is overlap in the size and shape of oocysts. Different studies indicated that species of Emeria are host and site specific and even they cause specific lesions within the specific sites. Therefore accuracy of diagnosis can be achieved with combination of different diagnostic tools including gross and histopathological lesions examinations.
