Contaminated Ventilator Air Flow Sensor Linked to Bacillus cereus Colonization of Newborns
Because of ubiquity in the environment, the recovery of Bacillus species from clinical specimens is often considered a clinically inconsequential contamination. Nevertheless, an accumulating body of literature suggests that contamination with this organism should not be routinely dismissed (1). Severe and lethal Bacillus cereus infections have been described in newborn infants, with higher frequency among premature infants. The types of B. cereus infections in newborns included central nervous system, respiratory tract, primary bacteremia, and sepsis (2–4). Nosocomial outbreaks of B. cereus implicating hospital linens, manual ventilation balloons, contaminated diapers, and contaminated ventilator equipment have also been reported (5–9).
