The present study aims to determine the incidence and risk factors of neonatal sepsis in a single center over a four-year period. Material and Method: This is a retrospective study of all cases of culture-proven neonatal sepsis admitted in the neonatal intensive care unit of a single center between January 2013 and December 2016. Clinical features, risk factors, microbiological and biochemical results, and mortality rates were recorded. Associations between risk factors and mortality were investigated. Results: The prevalence rate of neonatal sepsis was 2.7 per 1000 live births (94/30545) and 9.3 per 1000 neonatal admissions (94/10133). Low birth weight (<= 2500g) was recorded in 79 (84%) neonates with sepsis. There was at least one risk factor in all cases. Gram-negative bacteria were more frequently isolated than gram-positive bacteria (63.8% (60/94) vs. 29.7% (28/94)). Klebsiella pneumonia was predominant in both early-onset sepsis and late-onset sepsis (53% (16/30), 29.7% (19/64) respectively). Late-onset sepsis episodes attributed to Klebsiella pneumonia were associated with the highest sepsis-related mortality (41.7%). Discussion: Klebsiella pneumonia was found to be the most common agent in neonatal sepsis and responsible for sepsis-related mortality in this study. Prevalence of neonatal sepsis, its pathogens and risk factors differ in different parts of the world. Region-specific strategies to prevent new infections should be encouraged.en10.4328/JCAM.5774info:eu-repo/semantics/openAccessNeonatal SepsisNeonatal Intensive Care UnitArticle93187191#YOKWOS:000429961400002N/A
