Achromobacter xylosoxidans isolates in Hawaii.

Clinical and bacteriological features of nine cases in which Achromobacter xylosoxidans were isolated in Hawaii are described. Five cases were ear infections mixed with other gram-negative bacteria. Colonial morphology, xylose oxidation, peritrichous flagella staining, and antibiotic susceptibility pattern assisted in separating this bacterium from other nonfermentative, oxidase-positive, gram-negative rods.
