Sequences of Eimeria tenella ITS-l regions showed 100% homology with the Houghton strain and >90 homology was observed with the American, European and Chinese strains of tenella. These variations among the study isolates indicate diversity of eld isolates within the composite broiler belt. This strains needs to be further veried for the strain variation in E. tenella for the development of drug and vaccine to overcome the drug and vaccine resistance problemenArticle
