| Sumario: | Surgical site infections are among the most common postoperative complications, and the presence of multidrug-resistant bacteria in surgical environments increases the risk of nosocomial infections. In veterinary medicine, identifying these agents is essential to assess their impact and to strengthen biosafety measures. This study aimed to identify antimicrobial-resistant bacteria in surgical areas of veterinary clinics in Villavicencio, Meta. Three clinics with authorized surgical rooms were selected. In each facility, samples were collected from three sites (surgical table, air-conditioning system, and floor) at three surgical stages (preoperative, intraoperative, and postoperative). Samples were cultured on selective media, followed by antimicrobial susceptibility testing. The isolates consisted mainly of Bacillus spp. and Staphylococcus spp., with Bacillus spp. being more frequently detected on the floor and in the air, and Staphylococcus spp. predominating on surgical tables. No significant differences were observed among surgical stages (p = 0.731) or among sampled surfaces within operating rooms (p = 0.374); however, significant differences were found among clinics (p = 0.004), indicating variability in microbial load between facilities. Bacillus spp. exhibited resistance to ciprofloxacin and norfloxacin, whereas Staphylococcus spp. showed resistance to rifampicin and variable resistance to ciprofloxacin and trimethoprim. These findings highlight the need to strengthen cleaning, antisepsis, and disinfection protocols in veterinary operating rooms to reduce the risk of nosocomial infections and limit the spread of antimicrobial-resistant bacteria. |
