Neonatal early onset sepsis (EOS) diagnosis is difficult due to lack of sensivity and specificity markers. The investigators conduced a restrospectif study to all term born infants born between 1 january and 31 December 2013 and hospitalized for suspect EOS. The presence of neonatal symptoms at birth appears to be a useful clinical marker of probable neonatal EOS.

neonatal early onset spesis (EOS) remains animportant etiology of neonatal morbidity and mortality. Neonatal early onset sepsis (EOS) diagnosis is difficult due to lack of sensivity and specificity markers. Diagnosis is difficults due to lack of sensivity and specificity markers. The investigators conduced a restrospectif study to all term born infants born between 1 january and 31 December 2013 and hospitalized for suspect EOS.The objective of the study was to identify early clinical signs in newborn infants with suspected neonatal sepsis to differentiate a likely infection with pathogen bacteria in the gastric suction culture.The presence of neonatal symptoms at birth appears to be a useful clinical marker of probable neonatal EOS.
