Abstract Objective To analyze the distribution of pathogenic bacteria and drug resistance in patients with oral infection, and to provide reference for clinical drug use.Methods 86 cases of patients with oral infection were selected as study objects. The oral secreta were collected for pathogenic bacteria culture and drug sensitivity test was performed.Results Among the 86 patients, the proportions of patients who were ≤ 15 years old or ≥ 56 years old were relatively higher, which were 40.7% and 30.2% respectively. A total of 351 strains of pathogenic bacteria were detected, of which there were 236 strains of anaerobic bacteria, accounting for 67.2%. The proportion of black pigmented Prevotella was the highest (50.4%), followed by oral streptococci (16.5%), and there were 115 strains of aerobic bacteria, accounting for 32.8%. The drug resistance to oxacillin, ceftizoxime, gentamicin and ciprofloxacin was relatively higher, which were 49.2%, 46.6%, 42.0% and 40.2% respectively. The sensitivities to vancomycin, tetracycline and ceftriaxone were relatively higher, which were 98.3%, 95.8% and 93.6% respectively.Conclusion Anaerobic bacteria are the more common bacteria of oral infections. High-sensitivity drugs such as vancomycin, tetracycline and ceftriaxone can be used for treatment.

Key words： Oral infection Pathogenic bacteria culture Drug sensitivity test Drug resistance
