Coccidia are single celled protozoal organisms of the genus Eimeria. They have a complex life cycle involving both asexual and sexual reproduction. Disease due to damage to the intestinal mucosa can present in a variety of ways depending on factors including the age of the animal, its immune status and the level of
Cause. Coccidia are a complex and diverse group of protozoan. (single-celled organisms) parasites; the coccidia group con- tains many species, most of which do not cause clinical dis- ease. In birds, most disease-causing or pathogenic forms of coccidia parasites belong to the genus Eimeria. Coccidia usu- ally invade the

Coccidiosis causes considerable economic loss in the poultry industry. Chickens are susceptible to at least. 11 species of coccidia. The most common species are Eimeria tenella, which causes the cecal or bloody type of coccidiosis, E. necatrix, which causes bloody intestinal coccidiosis, and E. acervulina and E. maxima,
What are coccidia? Coccidia are small protozoans (one-celled organisms) , which are members of the class. Sporozoa ,an exclusively parasitic group that typically requires alternation of sexual and asexual reproduction in the life cycle. Some worker believe it is a yeast; however, until its taxonomic position and life cycle.

The numerous and widely scattered papers on Coccidia which are constantly appearing in journals of various types give ample support to the statement that these microorganisms have attracted numerous workers from many and diverse fields. It is becoming in- creasingly difficult for. even the specialist with good library
Coccidia. Cryptosporidium spp. Sporulated oocysts are shed in human stool and measure 4-6 µm in diameter. Sporozoites (up to four) are sometimes visible in mature oocysts. Oocysts can be difficult to detect in wet mounts (purple arrows, far left) and may be confused for yeast (brown arrow, far left). Trichrome stain is also
Coccidiosis can cause significant economic losses in cattle. Industry experts estimate the losses at $100 million each year. Although most cattle are exposed to coccidia and infected, many of the infections are self-limiting and mild or asymptomatic. The parasites that cause this condition are members of the genus Eimeria,
Coccidiosis in poultry is still considered as one of the main diseases affecting performance of poultry reared under intensive production systems. Although a lot of research efforts have been allocated towards molecular techniques, and a lot of progress has been noted in this field, practical use of these techniques.
