Abstract

Background: Poor air quality of healthcare-facilities, particularly the presence of airborne pathogens, has been directly linked to an increase of healthcare-associated infections. Objective: To survey of antibiotic resistance of bacterial strains isolated in the air at the Intensive Care Units of the University Medical Center, Ho Chi Minh City. Subjects and methods: Air samples were collected by machine five times, periodically every week in three Intensive Care Units. A descriptive cross-sectional method was used for analysis. Results: In 150 air samples collected, 76 bacterial strains were isolated and identified. Gram-positive bacteria predominated (77.6%); of which Staphylococcus epidermidis was the most common (43.4%). Pathogens included: Acinetobacter baumannii (9.2%); Enterobacteriaceaes (7.8%);  Staphylococcus aureus (7.9%). The average rate of CRAB (Carbapenem-Resistant Acinetobacter baumannii) was 71.4%. The Enterobacteriaceae group demonstrated a 100% resistance rate to both carbapenems and third-generation cephalosporins. The average rate of MRSA (Methicillin-Resistant Staphylococcus aureus) was 67.0%.
