• Resumen

  • Introduction: early-onset neonatal sepsis caused by Escherichia coli shows an increasing incidence, surpassing group B streptococcus in certain contexts, especially in the presence of maternal risk factors and prematurity. Case report: a case of a full-term newborn with risk factors of prolonged rupture of membranes and untreated maternal infection is presented. At twelve hours of life, the infant developed severe respiratory distress, fever, and hemodynamic compromise. Studies confirmed bilateral pneumonia and the isolation of ampicillin-resistant Escherichia coli in blood cultures. Management included mechanical ventilation and antibiotic treatment with ampicillin and gentamicin, later adjusted to cefotaxime according to microbial sensitivity. Conclusions: early diagnosis, immediate respiratory support, and the adaptation of targeted antimicrobial therapy are decisive factors in achieving survival and preventing serious complications in neonatal pneumonia caused by gram-negative bacilli.
