Resistance profile and biofilm production of microorganisms isolated in operating rooms.

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.
