We examined whether or not the genotype J could be detected among 21 new strains of T. equigenitalis isolated between 1994 and 1996 in Japan since our previous report (M iyazawaI et al. 1995). The respective pulsed‐field gel electrophoretic profiles of the 21 Japanese strains, as well as those of an old EQ59 used as a reference strain after separate digestion with the two restriction enzymes, Apa I and Not I, were essentially identical but differed from those of T. equigenitalis NCTC11184T and K entucky 188, respectively. Hence, the 21 strains and EQ59 appeared to have a common genotype J. Consequently, no strains of T. equigenitalis with any genotype other than genotype J may have reached Japan from 1980 to 1996 and strains with the genotype J have survived in Japan since the first invasion of contagious equine metritis into Japan.
