Bacillus cereus is becoming an important nomosomial pathogen because of frequent isolation from blood cultures and from severe systemic infections. To differentiate highly pathogenic outbreak strain of B. cereus from other sources of the Bacillus cereus, we attempted to analyze their dnaJ sequences. Assays indicated that dnaJ sequence similarity of all of 52 blood culture isolates of B. cereus ranged from 92.8% to 100%. The distance between B. anthracis and B. cereus except six outbreak isolates ranged from 3.8% to 6.4%. The dnaJ sequences of six outbreak strains of B. cereus (GTC 02891, GTC 02896, GTC 02916, GTC 02917, GTC…
