Abstract
Abstract The aim of this study was to identify the bacterial species circulating in various wards of the Emergency Clinical Hospital Constanta, involved in infections associated with hospitalization. Clinical specimens were obtained during 2016 year period. Identification of species and sensitivity tests were performed on VITEK 2 System. There were isolated 163 bacterial strains suspected to be responsible for infections associated with hospitalization. Surgery wards had the most important number of cases, 49% of all. The second most affected ward was neonatology (11%), as many as gynecology (5%) and pediatrics (6 %) together. According to the site of the infection, digestive are majoritary (42.94%), followed by surgical wounds (16.56%) and respiratory infections (15.33%). Septicemia cases (11.04%) are important due to the severity. Distribution on months varies between a minimum number of cases in January (5) and a maximum of cases in April (19).Gram-negative bacilli were the most frequently involved (49%). The most frequent species was Acinetobacter baumanii (28 cases), followed by Pseudomonas aeruginosa (15) and E.coli (7). Anaerobic bacteria (Clostridium difficile) are the second most important group (32% of the cases), followed by Gram positive cocci (15%) mostly staphylococci. Multidrug resistance was diagnosed in most Acinetobacter baumanii strains. A special attention must be given to associations of bacteria, that even though are in small number (2% of the cases), are more difficult to be treated.
