Abstract

Distribution and drug resistance of pathogenic bacteria in alveolar lavage fluid in elderly patients with invasive pulmonary fungal infection.

Abstract

Objective: To investigate the distribution and drug resistance of pathogenic bacteria in alveolar lavage fluid in elderly patients with invasive pulmonary fungal infection. Methods: The clinical data of 85 elderly patients with invasive pulmonary fungal infection were retrospectively analyzed. All the selected patients received alveolar lavage, and then the alveolar lavage fluid was collected for pathogenic testing and drug sensitivity test, and the test results were analyzed. Results: A total of 94 fungi were isolated from 85 elderly patients with invasive pulmonary fungal infections. Among them, Aspergillus, Candida albicans, and Candida krusei accounted for a relatively high proportion of 32.98%, 26.60%, and 12.77, respectively. %; Voriconazole and fluconazole are resistant to pathogenic bacteria in elderly patients with invasive pulmonary fungal infection, which are 30.85% and 35.11%, respectively. Conclusion: In elderly patients with invasive pulmonary fungal infection, the pathogens in the alveolar lavage fluid are mainly Candida albicans and Candida tropicalis, and the pathogens are relatively resistant to voriconazole and fluconazole. In the actual clinical treatment process, corresponding treatment can be given based on the results of drug sensitivity test.
