The aim of this study is to evaluate the association between maternal and neonatal surface colonization at birth and neonatal early onset sepsis (EOS). OBJECTIVE: To investigate the association of white matter hyperintensities (WMHs) present in the brain with AD CSF biomarker levels. METHODS: We conducted a case-control study of newborns admitted to the neonatal department of a referral women\u2019s and children\u2019s hospital from 2009 to 2017. Cases were infants with blood-culture-confirmed EOS (&lt;3 days of life), and controls were infants without EOS randomly chosen based on the cases\u2019 date of birth. Maternal genitourinary and neonatal ear swab cultures were used to determine bacterial surface colonization status. RESULTS: Fifty-one infants were diagnosed with EOS during the study period, where Escherichia coli (45%), and Group B Streptococcus (23%) accounted for 68% of infecting organisms. Compared to infants without EOS, those infected were more likely to have surface colonization of the mothers (60% vs 40%, p\u200a=\u200a0.048) and infants (90% vs 11%, p\u200a&lt;\u200a0.001). In univariate analysis, chorioamnionitis [7.1 (95% CI 2.9, 16.8)], small-for-gestational-age [OR 0.08 (95% CI 0.02, 0.4)], exposure to antibiotics around time of birth [2.3 (95% CI 1.0, 5.1)], maternal surface colonization [2.2 (95% CI 1.0, 4.9)] and neonatal surface colonization [23.5 (95% CI 7.3, 76.1)] were significantly associated with EOS. Adjusting for potential confounders, neonatal colonization remained significantly associated with neonatal EOS [AOR 15.0 (95% CI 3.5, 64.2), p\u200a&lt;\u200a0.001]. CONCLUSION: In our setting with predominant Gram-negative EOS, neonatal colonization but not maternal colonization was significantly associated with EOS in the newborn.<\/jats:p>","DOI":"10.3233\/npm-210978","type":"journal-article","created":{"date-parts":[[2022,7,5]],"date-time":"2022-07-05T11:42:54Z","timestamp":1657021374000},"page":"813-819","source":"Crossref","is-referenced-by-count":5,"title":["Perinatal
