Cough is one of the most common symptoms observed in patients presenting with COVID-19,persisting for an extended duration following SARS-CoV-2 *** aim to describe the distribution of airway microbiota and explore its role in patients with post-CovID-19 chronic cough.A total of 57 patients experiencing persistent cough after infection were recruited during the Omicron wave of SARS-CoV-2 in *** microbiota profiling is assessed in nasopharyngeal swab,nasal lavage,and induced sputum samples at 4 and 8 weeks after SARS-CoV-2 *** findings reveal that bacterial families Staph-ylococcaceae,Corynebacteriaceae,and Enterobacteriaceae are the most prevalent in the upper airway,while Streptococcaceae,Lachnospiraceae,and Prevotellaceae emerge as the most prevalent bacterial families in the lower *** increase in the abundance of Staphylococcus in nasopharyngeal swab samples and of Streptococcus in induced sputum samples is observed after one ***,the abundance of Staphylococcus identified in nasopharyngeal swab samples at the baseline period emerges as an insightful predictor for improvement in cough *** conclusion,dynamic alterations in the airway microbial composition may contribute to the post-coviD-19 chronic cough progression,while the compositional signatures of nasopharyngeal microbiota could reflect the improvement of this disease.
