Abstract：Objective:To explore the study value of wound bacteriology and drug sensitivity in patients with chronic ulcer.Methods:Seventy-four patients with chronic ulcers treated in yichun hospital of traditional chinese medicine from January 1,2023 to August 1,2024 were selected as the subjects of this study.Samples of chronic ulcer wounds were uniformly collected,and bacterial culture,identification and drug susceptibility tests were carried out in strict ac-cordance with laboratory requirements,and the test results were statistically analyzed.Results:Seventy-two strains of pathogenic bacteria and 28 strains of gram-positive bacteria were obtained from the wound secretions of 74 patients with chronic ulcer,of which 12 strains belonged to multidrug resistance and 10 strains belonged to Staphylococcus au-reus.The resistance rate of penicillin was the highest(92.86%),followed by that of cotrimoxazole(78.57%).There were 36 gram-negative strains,of which 30 belonged to multidrug resistance and 22 belonged to Enterobacteriaceae.Meropenem had the highest resistance rate(77.78%),followed by ampicillin(72.22%).Conclusion:Clinical treatment of patients with chronic ulcers should be combined with the results of drug sensitivity test to select reasonable antibiot-ics for effective treatment to avoid the proliferation of drug abuse.
