Abstract:
Objective To summarize the characteristics and sources of infection risk of Bacillus cereus(B.cereus)septicemia in low birth weight(LBW)infants,and provide reference for infection prevention and control.Methods Characteristics of 3 LBW infants with B.cereus septicemia were reported and analyzed,relevant literatures were searched for systematically summarizing the characteristics and sources of infection risk of B.cereus septicemia in infants.Results Among 3 LBW infants reported in this paper,2 died and 1 was cured.No clear infection source was found in the environment through object surface sampling analysis.A total of 43 cases were reported in the pre-vious literatures,41 cases had reported on survival status,the mortality was 36.6％.The main risk factors for in-fection were auxiliary ventilation,umbilical vein catheterization or central vein catheterization and enteral feeding.In the reported 3 cases with clear sources of infection,the pathogens came from mother's milk,decoration area,sur-face of infant incubator and ultrasonic probe.Conclusion Premature LBW infants with B.cereus septicemia have high mortality and poor prognosis,which is a healthcare-associated infectious disease seriously threatening the life and health of LBW infants.Neonatal intensive care unit(NICU)and relevant departments of healthcare-associated infection(HAI)management need to pay attention to the prevention,monitoring,early detection,as well as active diagnosis and treatment of HAI caused by this bacteria.
