Abstract INTRODUCTION: Morganella morganii is a facultative anaerobic gram-negative bacillus that has been described as a cause of neonatal sepsis, meningitis and chorioamnionitis, however in observational studies it has been reported as a rare cause. CASE SUMMARY: 36-year-old pregnant patient, gravida 2 cesarean sections 1, with 24.1 weeks of gestation presented with chorioamnionitis caused by Morganella Morganii with comorbidity of recent SARS-COV2 infection. Termination of pregnancy by cesarean section was required, associated with fatal neonatal outcome. She received dual antibiotic therapy without experiencing any other maternal complications. CONCLUSION: Chorioamnionitis caused by M. morganii is a rare entity but represents a significant cause of morbidity for the maternal-fetal binomial. It is important to identify other comorbidities in pregnant women that can be considered as possible predisposing factors for this entity, so early identification and treatment should be sought.
