*ICU, intensive care unit; NA, not applicable. All but 1 patient (with strain 07AC–192) had mechanical ventilators. Four patients (with strains 07AC–159, 07AC–192, 07AC–336, and 07AC–063) were immunocompromised hosts who had daily administration of corticosteroid (>20 mg/d of prednisolone or an equivalent drug) during >2 wk and treatment with chemotherapy for an underlying malignancy during 1 month before hospital admission.
†Infection is defined as invasion of the body tissues by microorganisms resulting in disease.
‡Colonization occurs when an agent’s presence in a host does not cause a specific immune response or infection.
