ABSTRACT

Preterm birth rates are increasing everywhere., more frequency in premature is responsible about 75% of morbidity and 70% of mortality in the neonatal period in developing countries. Our study aimed to analyze the blood culture results of preterm neonates in neonatal intensive care units (NICU), calculate the positivity rate, time of onset, spectrum of organisms, antimicrobial susceptibility pattern of these microorganisms, the risk factors associated with positive blood cultures and the development of the infection. The study was designed as a retrospective epidemiologic analytical study, neonatal intensive care unit of Al Hussein hospital was included, the blood cultures for preterm were listed during July 2018 and March 2019. Data of positive blood cultures including identification of microorganisms and susceptibility pattern were obtained. (74%) of Neonates had less than 37 weeks ,(13%) of premature had bacteremia, EoNS and LoNS constituted (22%) and (78%) respectively, 46% of preterm deaths in infants less than 37 weeks old were caused by septicemias, Gram negative bacteria was the most common causes of bacteremia ( 56%), Gram positive bacteria was the most common causes of bacteremia in EoNS that causes 47% of infection and the 3 isolated bacterial families (Acinetobacter baumannii, Enterobacter cloacae, and Pseudomonas aeruginosa) were from 88% to 100% resistant to most antibiotics.
