Pathogen Distribution and Antibiotic Resistance of Breast Abscess in a Certain Hospital from 2016 to 2023
OBJECTIVE To study pathogen distribution,and drug resistance of breast abscess in our hospital in order to provide a reference for using antibiotics reasonably.METHODS A retrospective analysis was conducted on the types of pathogenic bacteria of breast abscess pus culture positive specimens in our hospital from January 2016 to November 2023,and the drug sensitivity characteristics of common pathogens were analyzed.RESULTS There were a total of 192 patients with breast abscess,including 89 lactating patients and 103 non-lactating patients.192 strains of pathogens were isolated from pus samples,including 185 strains of gram positive bacteria which consisted of 108 strains of Staphylococcus aureus,31 strains of coagulase negative Staphylococcus,30 strains of Corynebacterium,15 strains of Streptococcus,and 1 strain of Enterococcus faecalis;7 strains of gram-negative bacteria,which included 5 strains of Enterobacteriaceae.The resistance rates of Staphylococcus aureus and coagulase negative Staphylococcus to oxacillin were 37.0％and 58.1％,respectively.The sensitivity rates to vancomycin,teicoplanin,and linezolid were all 100％.CONCLUSION There are more non-lactating patients with breast abscess in our hospital,and the pre-dominant pathogens were Staphylococcus aureus.The isolation rates of MRSA and MRCN were high,and pathogen culture and antimicrobial susceptibility testing should be carried out as soon as possible,to develop a reasonable anti-infection treatment plan.
