Considerații privind implicarea în infecții la pacienți spitalizați și rezistența la antimicrobiene a Serratia species |[Considerations on Involvement in Hospitalized Patients and Antimicrobial Resistance of Serratia species]

Abstract

The purpose of this retrospective study was to dynamically analyze the spectrum of infections produced by Serratia spp. and resistance to antibiotics of the isolated strains. The study group included 259 Serratia strains isolated from various pathological products collected from patients hospitalized in the Clinical County Emergency Hospital of Brasov during a 3-year period (2014-2016). The results showed that these germs were more commonly involved in urinary infections (48.65%), infected varicose ulcers (16.22%), wound infections (16.22%), and low respiratory infections (10.81%). The resistance of Serratia strains to ß-lactams was high, with the exception of imipenem (1.65%). For aminoglycosides, the resistance was higher for gentamicin (66.36%). For quinolones, the resistance was high in nalidixic acid (91.67%) and norfloxacin (62.5%). The share of ESBL strains was high during the study period (49.81%). The study reveals the involvement of Serratia in infections in hospitalized patients and the importance of monitoring multiresistant strains.
