Contamination of Bacillus Species Sepsis.
Contamination of Bacillus Species Sepsis.
Bacillus species are ubiquitous gram-positive spore-forming organisms. They rarely cause
 disease in the immunocompetent and are more frequently isolated as a culture contaminant.
 However, Bacillus Species can cause severe systemic infections in immunocompromised patients
 including preterm infants.

 The purpose of this study is to identify the risk factors of these infections.
Non-anthrax Bacillus Species bacteria can be responsible for food poisoning and local
 infections. Rarely, they lead to severe infections like blood stream infections and
 meningitis especially in immunocompromised patients like preterm infants.

 Bacillus Cereus is the most common members of the genus Bacillus. Only few reports studied
 these systemic infections in premature neonates. In order to identify the risk factors for
 severe Bacillus Species infections, we studied retrospectively eleven cases of these
 infections in our NICU and reviewed series and report cases in literature.
Inclusion Criteria:

 -  cases of Bacillus Species sepsis

 -  cases of Bacillus species meningitis

 -  with significant change in clinical status

 -  Bacillus Species is the only organism isolated

 Exclusion Criteria:

 -  Bacillus Species isolated with other organisms and Bacillus Species without clinical
 change were considered to be contaminants
