Model Study: The genus Acinetobacter is composed of opportunistic pathogens that mainly affects immunocompromised and patients during a prolonged hospitalization period. A. baumannii can survive in the hospital setting at various locations such as mechanical ventilators, dialysis machines, ventilation systems, water sources, skin and mucous membranes of health professionals and patients, drug preparations and disinfectants among others. Antimicrobials are essential for the treatment of infections, so their use has become common, and often inappropriate and abusive. This pathogen has presented multi-resistance to several classes of antimicrobials and has become a major cause of death in hospitals. Objective: To evaluate the occurrence of Acinetobacter baumannii in clinical samples from the Laboratory of Clinical Analyzes, HCSL of Pouso Alegre, MG. Methods: All the samples referring to the patients of the Samuel Libanio Clinical Hospital including most of the specialties were evaluated. From the positive samples for Acinetobacter baumannii the medical records of hospitalized patients were evaluated. From the medical records, data were obtained as gender and age of the patient, place of hospitalization, together with month and year of the laboratory procedure. Result: A total of 14,859 samples of diverse materials were evaluated, being 80 (0.5%) samples positive for Acinetobacter baumannii. Of these positive samples, the largest occurrences were identified in male patients 59 (73.7%), aged over 60 years 37 (46.3%). The most affected hospital sector was Adult ICU with 44 (55.0%) of the cases. In May 2015, there were 5 (6.3%) cases registered and in May 2016, 16 (20.0%) cases. The clinical material with the highest occurrence of Acinetobacter baumannii was Mini Bal 29 (36.3%). Conclusion: Acinetobacter baumannii has been presenting a major increase in clinical samples from the lungs, mainly from male, elderly patients hospitalized in an intensive care unit and with resistance to Polimixin.
