Abstract
This study presents the data about the restriction polymorphism of group B streptococcal insertion sequences (IS elements). A total of 29 out of 113 strains did not possess any of the IS elements studied. In other strains the number of different IS elements varied from 1 to 3. No strains with 4 different IS elements were discovered. A total of 6, 9, 13 and 38 different DNA restriction patterns, hybridizing with IS1548, IS861, ISSa4 and IS1381 probes, respectively, were found out among the strains tested. It was demonstrated that IS based typing together with serological typing could be effectively used for epidemiological assay.
