Objective: We aimed to evaluate the antibiotic susceptibility pattern of non-fermantative gram negative bacteria isolated from different Intensive Care Units.
Study Design : In this study, Acinetobacter and Pseudomonas species isolated from samples sent by different Intensive Care Units of Şişli Etfal Training and Research Hospital were identified with conventional microbiological methods. The activity of the antibiotics to the species in vitro was perfoimed by using disc diffusion method according to NCCLS criteria and these intermediately susceptible were accepted as resistant.
Results: In our study totally 77 bacteria Acinetobacter spp and 32 Pseudomonas spp respectively isolated from different samples were evaluated. Carbapenems were the most active antibiotics for both Acinetobacter and Pseudomonas species whereas the activity of other antipseudomonal antibiotics was definitely diminished.
Conclusions : Intensive Care Units are hospital units where antibiotics are frequently used and the prognosis of infections caused by resistant organisms is worse. For optimal "empirical treatment and in order to prevent nosocomial infections any hospital should assume its own data for antibiotic susceptibility
