Eimeria is a genus of apicomplexan parasites that includes various species capable of causing the disease coccidiosis in animals such as cattle, poultry and smaller ruminants including sheep and goats. [2]
The diagnosis is made by microscopic examination of the stool. Distinguishing between the species of Cystoisospora is most easily done with PCR. This method can also be used to make the diagnosis. Treatment is based on trimethoprim-sulfonamides with clindamycin or toltrazuril for resistant strains. [6]
Fish food should ideally provide the fish with fat (for energy) and amino acids (building blocks of proteins) and the fish food (whether flake or pellet) must be speedily digested in order to prevent buildup of intestinal gas, kidney failure and infections (such as swim bladder problems and dropsy) and to avoid aquarium pollution due to ...
For example, the U.S. biotechnology company BioTork is piloting the use of raw materials such as unmarketable papaya and by-products from biodiesel production to produce fish feed components, [9] as well as feeding agricultural waste to algae and fungi that manufacture some of the proteins and omega-3 oils needed for fish food.

The main difference between the coccidians and the gregarines is in the gamonts. In the coccidia, these are small, intracellular, and without epimerites or mucrons. In the gregarines, these are large, extracellular, and possess epimerites or mucrons. A second difference between the coccidia and the gregarines also lies in the gamonts.
These small fish maintain so-called "cleaning stations" where other fish, known as hosts, will congregate and perform specific movements to attract the attention of the cleaner fish. [26] Cleaning behaviours have been observed in a number of other fish groups, including an interesting case between two cichlids of the same genus, Etroplus ...
Eimeria tenella has a monogenetic life cycle, that is, the life cycle involves a single host. [2] Various stages of its complicated life cycle may conveniently be described under two phases, asexual cycle or schizogony and sexual cycle involving gametogony. Much of life cycle is intracellular.
Cystoisospora belli, previously known as Isospora belli, is a parasite that causes an intestinal disease known as cystoisosporiasis. [1] This protozoan parasite is opportunistic in immune suppressed human hosts. [ 2 ]
