Fifteen patients (55.6%) achieved negative conversion at 2 weeks, sustained in 93.3% at 6 months. Responders showed signifcantly decreased fecal microbiota diversity at 2 weeks, unlike nonresponders (P = .029). Increased abundance of Eubacterium hallii in baseline fecal microbiota was indicative of unresponsiveness, whereas increased Enterococcus in feces at 2 weeks was linked with favorable response. In sputum, high baseline levels of Burkholderia-Caballeronia-Paraburkholderia and Porphyromonas, along with decreased Rothia at 2 weeks, were associated with good treatment response.<\/jats:p>\n
