LNNBI still represents an important cause of mortality and morbidity among infants. Objectives: To determine the frequency of late bacterial infections in newborns, to describe the clinical and biological profiles and to identify the main responsible germs. Methods: Descriptive study data collection, conducted over a period of 10 months at the Brazzaville Teaching Hospital, of interest to newborns admitted from the 4<sup>th</sup> day of life for suspicion of neonatal infection, and those admitted for any other pathology and having presented an infection 48 hours after hospitalization, and in whom a bacterial culture and/or an inflammatory assessment confirmed or suspected infection. Results: During the study period, 1682 newborns were hospitalized, and 86 were hospitalized for a late neonatal bacterial infection, i.e. a frequency of 5.1%. There were 67 (77.9%) community infections and 19 (22.1%) nosocomial infections. The frequency of nosocomial infection was 1.1%. The main signs were fever in 65 cases (75.6%), and respiratory distress in 37 cases (43%). The most frequent localizations were bacteremia 32 (37.2%), pulmonary 21 (24.4%), digestive and meningeal in 11 cases (12.8%) each. The most common germ Klebsiella in 10 (50%) newborns was resistant to the usual antibiotics. The evolution was favorable in 71 cases (82.5%), and death occurred in 12 cases (14%). Conclusion: Late neonatal bacterial infection is common. The main responsible germs are gram-negative bacilli, in particular Klebsiella multi-resistant.展开更多
