Background • Community acquired Extended Spectrum β-Lactamase producing Enterobacteriaceae (ESBL-PE) pandemics, 1990 s-today • Enterobacteriaceae (EB) cause early and late onset neonatal sepsis • The burden of EB sepsis is especially high in Neonatal Intensive Care Units (NICU) 3

Background • Routine urinary cultures are taken during pregnancy • Treatment of asymptomatic bacteriuria in pregnancy prevents pyelonephritis and premature labour • No data about the significance of these cultures for vertical transmission to neonates 6
Objectives • Primary - to find out association between the presence of ESBL-PE in gestational urine cultures and ESBL-PE in the corresponding neonates' cultures • Secondary - to analyze the effect of ESBL-PE on neonatal morbidity and mortality 7
Methods • Retrospective cohort study of neonates born during the years 2009 -2013 whose mothers had performed urinary cultures within one year prior to delivery • Data were obtained from the centralized Clalit Health Services warehouse • The cohort included only neonates who had any type of positive EB culture during the first three months after birth 8
Results 137, 580 neonates Flowchart of the Study Population born in 2009 -2013 to mothers who performed urinary culture 31, 921 (23. 2%) neonates performed any type of culture 2, 647 (8, 3%) neonates with positive cultures 105, 659 did not perform any culture in the 3 months after delivery (excluded) 29, 274 neonates with negative cultures (excluded) 290 (11. 0%) ESBL-PE positive cultures 9

Trends for ESBL-PE proportion in the EB positive neonatal cultures (n=2, 647) Total rate for 5 years cohort = 11% 11
Primary Objective 12
Secondary Objective 1 Neonates length of hospital stay during the 3 months after birth 13
Secondary Objective 2 14
Conclusions • ESBL-PE in maternal urinary culture during pregnancy is an independent risk for neonatal ESBL-PE • Neonatal ESBL-PE are associated with increased hospital stay and mortality • Comprehensive infection control policy in NICU should take in consideration the results of maternal urinary cultures 16
