FIG. 2.

Schematic representation of polymorphism in locus 1-2 among the Japanese isolates and reference strains. The numbers shown correspond to nucleotide numbers of locus 1-2 of HM-1:IMSS cl9 (GenBank/EMBL/DDBJ accession number AF276055). Sequences prior to nucleotide 30 are not shown because these nucleotides overlap the PCR primer. Gaps are introduced to optimize alignments. Conserved regions are highlighted with gray rectangles. Names of reference strains previously reported are underlined, and those analyzed in this study are double underlined. Previously unidentified repeats units are also included in this and following figures. A T-to-C nucleotide substitution is indicated by an arrow. An asterisk next to an isolate designation indicates that more information can be found in reference 34.
