OBJECTIVES: to evaluate the resistance profile and biofilm formation in isolates from operating rooms in two hospitals in the southwestern region of Goiás.
METHODS: an experimental laboratory study was conducted, with samples collected between March and August 2023.
RESULTS: of the 50 samples collected, 104 bacteria were isolated, 81.7% (85/104) gram-positive and 18.3% (19/104) gram-negative. Of these, 55.3% (47/85) of the Staphylococcus genus were classified as multidrug-resistant and methicillin-resistant, and 15.7% (3/19) of the Gram-negative bacteria were classified as multidrug-resistant. 66.34% (69/104) were biofilm producers, with 79.7% (55/69) being Gram-positive and 20.3% (14/69) Gram-negative.
CONCLUSIONS: this finding is of great concern, as these microorganisms in hospital environments pose a high risk for surgical site infections that are difficult to treat due to multidrug-resistant strains.
