Resistant bacteria cause urinary tract infection in graduates of neonatal unit

Abstract Pattern of bacteria that causes urinary tract infection (UTI) in infants after discharge from neonatal intensive care units (NICU) are not well described. This Study included 74 patients with first episodes of UTI in the first 3 months of life. They were divided into 2 groups, 31 case occurred during NICU stay (group 1), 43 cases with UTI that occurred after discharge from NICU (group 2, NICU graduates). Types of bacteria, its susceptibility to common antibiotics, renal abnormalities and circumcision status were compared between both groups. Eighty two percent of patients in the both groups were male. Between 71.9%–74.4% of patients in both groups were preterm. Among NICU graduates, Incidence of UTI in infants who were preterm and those who were term was 8.2% and 2.1% respectively p < 0.001. The most common causative bacteria in both groups were Klebsiella pneumoniae and Escherichia coli. Bacteria that caused UTI in NICU graduates were highly resistant to common antibiotics and were similar (in types and the resistance) to bacteria that caused UTI in patients during stay in NICU. UTI in NICU graduates happen frequently in premature, young male infants. Their UTI were caused by bacteria that are similar in type and resistant pattern to those cause UTI in NICU patients.
