Abstract
We have found a new insertion sequence (IS), designated ISAa1, downstr eam of the S10 operon in Actinobacillus (Haemophilus) actinomycetemcom itans FDC Y4. ISAa1, the first IS element characterized in this organi sm, is 705 bp long and lacks terminal inverted repeats. This element d isplayed significant homology with IS200. Hybridization patterns of ge nomic DNA of seven A. actinomycetemcomitans strains with an internal I SAa1 probe varied depending on the serotypes, suggesting that ISAa1 mi ght be a useful tool for epidemiological studies.
