A novel insertion sequence element of the IS<i>982</i> family, IS<i>Scr1</i>, was previously identified in <i>Streptococcus criceti</i> strain E49 as a disrupted <i>paaB</i> gene encoding an antigen I/II homologous protein. In this study, we identified two divergent inserted regions of IS<i>Scr1</i> in <i>S. criceti</i> E49 by inverse polymerase chain reaction, the gene-walking method, and screening of the partial plasmid library. Nucleotide sequence analysis indicated the possible explanation that transposition generated 8- and 9-bp direct repeat sequences. DNA hybridization analysis revealed that an identical hybridization pattern to IS<i>Scr1</i> was observed in the four <i>S. criceti</i> strains studied and that at least three copies of IS<i>Scr1</i> were preserved in <i>S. criceti</i> strains. In addition, we found different susceptibility to erythromycin and diverse agglutination properties induced by dextran in <i>S. criceti</i>. Furthermore, DNA hybridization analysis showed that no IS<i>Scr1</i>-like copy was detected in the other 14 strains of oral streptococci tested.
