肺炎作为一种感染性疾病,检出病原微生物即可确诊。但在社区获得性肺炎的初次诊断中很少能检出病原菌,或者由于病原菌培养需时较长,最初只能凭经验做诊断。有人认为治疗肺炎不需要检出病原菌,然而若能快速查出致病菌,从而选择合适的药物,可以避免细菌对药物的耐受性,减少治疗费 As an infectious disease, pneumonia can be diagnosed by detecting pathogenic microorganisms. However, pathogenic bacteria are rarely detected in the initial diagnosis of community-acquired pneumonia, or due to the longer pathogen culture, diagnosis can only be done empirically at first. Some people think that the treatment of pneumonia does not require detection of pathogens, however, if rapid detection of pathogens, which can choose the right drugs, to avoid bacterial resistance to drugs, reduce treatment costs
