Because of their specificity, infections in neonatal units form one of the main clinical problems. Our research involved all neonates (1019) hospitalized in Clinic of Obstetrics and Perinatology within the space of one year. Clinically manifested infections were diagnosed in the total number of 47 (4.6%) newborns, including 23 (2.4%) neonates from the neonatal unit (NU) and 24 (46.2%)--from the Neonatal Intensive Care Unit (NICU). In both units, the most commonly observed were general infections (59.6%) and pneumonias (21.3%); cerebrospinal meningitis and necrotic enteritis were diagnosed in a few cases. Urinary system infections were only found in neonates hospitalized in the NU (30.5%). The course of infection was mild in most cases.
