Microbiology of surgical site infections in patients with cancer: A 7-year review

GNB caused most SSIs, with an increase of ESBL E coli strains. In breast and thoracic surgery, S aureus remained the most frequent isolate. MRSA remained stable throughout the study period. We observed a decreasing trend in S aureus. These findings show the differences in the microbiology of SSIs in a middle-income country and the increasing trend of ESBL enterobacteria and other multidrug-resistant organisms, such as Enterococcus faecium.
