Flowchart of Anticoccidial Drugs
anticoccidialdrugsflowchart-chicken

Figure 1. A summary of different types of anticoccidial drugs and their effect and mechanism of action towards certain chicken Eimeria species.  Anticoccidial drugs can be categorized as a coccidiostat or a coccidiocide based on their effect on Eimeria. Some drug types can act as both a coccidiostat and a coccidiocide depending on the species of Eimeria being acted against.  The mechanisms of action for some drug types are known, although the process for selective effects against certain Eimeria species is poorly understood (5-8).
