Enterobacter, the most common pathogen of neonatal septicemia in Rasht, Iran

ABSTRACT

Bacterial sepsis continues to be a major cause of morbidity and mortality in newborns. Bacterial pathogens of neonatal septicemia may vary from one country to another and within a country from one hospital or region to another. Both gram-negative and gram-positive bacteria are responsible in neonatal sepsis. This study was undertaken to determine the prevalent bacterial agents of neonatal sepsis and their antimicrobial susceptibility in a teaching hospital, Rasht, from February 2008 to February 2010. This prospective study includes 611 newborns admitted with the probable diagnosis of septicemia. We studied the cases with positive blood culture, the pathogens and antibiotic resistance to different antibiotics. Among 611 hospitalized newborns, 64 [10.6%] cases had positive blood culture. The commonest pathogens were Entrobacter [78.1%] and Klebsiella [6.2%]. According to the results, low birth weight and prematurity were associated with higher risk of sepsis significantly. The most common pathogen was Enterobacter. Treatment with effective antibiotics [e.g. gentamicin, cost effective and easily available] and hygienic care in the neonatal unit are recommended to eliminate the infectious factors especially Entrobacter
