Extensive use of anticoccidials has led to the development of anticoccidial drug resistance. This review article focuses on the evolution of anticoccidial drug resistance, types of resistance, factors favouring development of resistance, mechanisms of development of resistance, indices for detection of resistance and solutions and alternate approaches to overcome the problem of anticoccidial drug resistance.en-USVeterinary ScienceVeterinary ParasitologyArticle
