DNA Polymorphism of srRNA Gene among Eimeria tenella Strains Isolated in Japan

Abstract

DNA polymorphism in twelve starains of Eimeria tenella isolated from various places in Japan was examined using 1.1 kb small subunits ribosomal RNA amplified by PCR. Genetic variation was evaluated by random amplification of polymorphic DNA (RAPD) analysis. DNA fingerprint patterns were grouped into two, indicating that at least two DNA polymorphisms exist in Japanese E. tenella strains.
