Abstract Background and Objective: Premature neonates, low birth weigth neonates weighing less than 2 kg or neonates with severe health problems kept at N.I.C.U are highly at risk of contracting nosocomial infections, in particular septicemia. Therefore, we decided to investigate the prevalence of bacteria in this ward. Materials and Method: In this descriptive cross-sectional study, 100 hospitalized neonate in-patients in NICU were studied. Samples were taken from five parts of the neonates' body (rectum, skin, nose, pharynx and umbilicus) in three turns for microbiological analysis in the laboratory. Blood samples were also taken from neonates hospitalized with blood infection for microbiological analysis. Results: Results of this study showed the bacteria identified in different parts of the neonate΄s body were Staphylococcus epidermidis, Klebsiella pneumonia and Escherichia coli in the amount of 484, 243 and 191 respectively. Also, 7 cases of septicemia caused by Staphylococcus epidermidis, Klebsiella pneumonia and Escherichia coli were observed, the number of cases being 4, 2 and 1 respectively. Conclusion: As the results of this research shows Staphylococcus epidermidis, Klebsiella pneumonia, Escherichia coli and Staphylococcus saprophyticus are the main cause of microbial colonization and septicemia in the neonates.
