Abstract

Sixty four clinical isolates were collected from children with Necrotizing Enterocolitis admitted to the Children's Protection Hospital at the Medical City in Baghdad. These isolates included (41) stool samples, (14) blood samples and (9) urine samples for the period from 29/1/2018 to 4/4/2018. All the samples were cultured on MacConkey agar and Blood agar for diagnosis. All isolates were identified depending on macroscopic, microscopic, and biochemical tests, with Vitek-2 compact system. Forty three isolates were obtained from all samples; (26) isolates as Klebsiella pneumoniae (60.46%), 8 isolates as Escherichia coli (18.60 %), 4 isolates as Pseudomonas aeruginosa (9.30%), 2 isolates as Klebsiella oxytoca (4.65%), 2 isolates as Enterobacter cloacae (4.65%) and 1 isolate as Proteus hauseri (2.32%).The results showed that K. pneumoniae was the predominant in the samples taken from infants infected with Necrotizing Enterocolitis .
