نبذه مختصره عن تاريخ anti coccideal



	<table cellSpacing=0 cellPadding=0 border=0><tr><td>History of Anticoccidial Drugs The history of coccidiosis drugs is closely tied with the control of the problem in poultry, because the importance of coccidiosis in other species had not been recognized until recently. Treatment of coccidiosis began about 60 years ago in response to an outbreak, and was done mainly with sulphonamides—the drugs available for the treatment of the disease at the time. In 1948, USA poultry producers found that the preventative approach of continuously feeding Sulfaquinoxaline was by far the most economical way to control the problem because it prevented not only mortality but also morbidity from coccidiosis. Various anticoccidials have been developed since the 1950s. Some of the old chemicals such as Amprol and Nicarbazin are still in use today. Many others are no longer used because of toxicity problems or a lack of efficacy as a result of the development of resistance by Eimeria. In the 1970s, a new class of antibiotics, called ionophores, was discovered, which virtually replaced the earlier chemical compounds. Ionophores are unique, because they permit a small "leakage" of coccidia to enable the bird to develop a certain level of immunity. This allows a greater degree of protection against the parasite and is a very efficient method of control. Today, some vaccines are available for controlling the Coccidia problem in the poultry segment. Baycox (toltrazuril) was first produced by Bayer in the 80s, and is a chemical substance that belongs to the class of “symmetric triazinons”. It was introduced to the market in 1986, and due to the fact that it affects all intracellular stages of Eimeria, it has been used with excellent results to combat coccidiosis problems in various animal species since its launch.</TD></TR></TABLE>
