- Clinical cultures—cultures done on suspicion of infection
- Surveillance cultures—cultures done on admission from anterior nares, umbilical swabs, respiratory secretions and rectal swabs and weekly during the NICU stay from respiratory secretions and rectal swabs
- Surveillance culture positive—with regard to culture positive infection episodes, if we have isolated the same organism in a surveillance sample beforehand or with regard to culture negative infection episodes, if we have isolated a possible pathogenic organism as a colonizer in any surveillance sample
- Surveillance culture negative—with regard to culture positive infection episodes, if we have not isolated the same organism or isolated a different organism in any of the surveillance samples beforehand. With regard to culture negative infection episodes, if we have not isolated any possible pathogenic organism as a colonizer they were also considered as screening negative occasions
