Study on the Sensitivity of Microorganisms to Antibiotics of Various Classes

Abstract

This study collected throat swab samples from patients with chronic tonsillitis and successfully isolated four strains of bacteria, including both Gram-positive and Gram-negative bacteria, using broth culture medium. Subsequently, the Kirby-Bauer disk diffusion method was employed to assess the sensitivity and resistance of these strains to four commonly used antibiotics. The findings not only clarified the antibiotic sensitivity profiles of the different strains but also provided scientific evidence and guidance for the selection of antibiotics in the clinical treatment of chronic tonsillitis. This research contributes to optimizing treatment strategies and reducing the misuse of antibiotics.
