✦ Synopsis
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 (MIYAZAWA 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, ApaI and NotI, were essentially identical but differed from those of T. equigenitalis NCTC11184 T and KENTUCKY 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.
