Abstract The aim of this study was to investigate the relationship between microorganisms isolated from neonates and those isolated from surrounding area , common infection sites and pathogens in neonatal intensive care unit in Zagazig University Hospitals . Also, to evaluate the efficacy of combination of disinfectants solutions to prevent and eradicate biofilm formed and to suggest a new lock solution that can prevent attachment of bacteria to rayls, catheters and cannulas. A total 470 isolates were recovered from the samples. The isolates were identified as: Staphylococcus aureus(150),coagulase negative staphylococci (150),Pseudomonas aeruginosa (50), Klebsiella pneumonia(100) and no organisms were detected in 20 samples.Specimens from skin of neonates revealed that most commonly isolated organisms were S. aureus (37.5%), CoNS (37.5% , K. pneumoniae (18.75) and P. aerguinosa (6.25%) . Samples from bottle of milk feeding , feeding tube and pans of water keeping revealed the presence of S. aureus , CoNS , P. aerguinosa and K. pneumoniae . In this study the most commonly isolated organisms from incubators were CoNS (33.75%, S. aureus (31.25%) , K. pneumonia (16.25%) and P. aerguinosa( 8.75%). The obtained results in this study exihibited that ,the isolates from hands of health care workers were CoNS (37.5%), S. aureus (31.25%), K.pneumoniae (21.25%), P. aerguinosa (3.75%). In the present study the enviromental samples (including walls, doors, tables of medications, sinks and floors of neonatal intensive care units ) revealed the presence of S. aureus (33.75%) , CoNS(28.75%), P. aerguinosa (18.75%) and K. pneumoniae (18.75%).Samples from disinfectants solutions revealed the presence of S. aureus , CoNS , P. aerguinosa and K. pneumoniae. In this study the most frequently isolated organisms from NICU were S. aureus (31.9%), CoNS (31.9%) , P. aerguinosa(10.6%) and K. pneumonia ( 21.28%). |
