    Mycoplasma pneumoniae disease is a kind of respiratory diseases. Because of its special pathogenic mechanism, it not only causes damage to the respiratory tract of patients, but also may induce other systemic diseases and produce a variety of complications, which greatly threaten the lives of patients. It has been found that the high incidence of Mycoplasma pneumoniae disease population is in children, and the scope and symptoms of children's infection are gradually increasing. Due to the widespread use of antibacterial drugs, the pathogens produce drug resistance, which leads to great difficulty in clinical treatment. In this paper, the literatures of clinical manifestations and clinical treatment of Mycoplasma pneumoniae infection were reviewed, and the research progress was analyzed.

    Objective: To analyze the influence of ear canal secretion's bacterial culture and drug sensitivity test results on rational usage of antimicrobial agents in 66 elderly patients with chronic suppurative otitis media (CSOM). Methods: The medical records of 66 elderly patients with CSOM admitted to our hospital from January 2018 to October 2019 were selected. The bacterial culture and drug sensitivity test results of ear canal secretions were calculated, and the distribution of pathogenic bacteria in the secretions and the characteristics of drug resistance to common antibacterial drugs (penicillin, erythromycin, rifampicin, vancomycin, etc.) were analyzed. Results: 70 strains of pathogenic bacteria were cultured from the secretions of 66 CSOM patients, of which 44.29% were Gram-positive bacteria, 41.43% were Gram-negative bacteria and 14.28% were fungi. In the Gram-positive bacteria, the main pathogens (Staphylococcus epidermidis and Staphylococcus aureus) were highly sensitive to vancomycin, rifampicin, tigecycline, linezolid and furantoin. The main Gram-negative bacteria (Pseudomonas aeruginosa and Klebsiella pneumoniae) were highly sensitive to imipenem, meropenem, ceftazidime, piperacillin-tazobactam and cefoperazone/sulbactam. The main fungi (Candida albicans and Aspergillus) were also sensitive to 5-fluorocytosine, nystatin, amphotericin B, etc.. Conclusion: The main pathogens of CSOM infection were Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Candida albicans and Aspergillus. In clinical treatment, antibacterials with high sensitivity rate could be selected based on the drug sensitivity test results of these pathogens to ensure the clinical efficacy.
