Using invasive sampling methods, such as bronchoalveolar lavage (BAL) or transtracheal aspiration (TTA), the LRT has been shown to host a low-biomass core microbiota dominated by Pasteurellaceae, Mycoplasmataceae, Flavobacteriaceae, Clostridiaceae, and Prevotellaceae, while archaea, viruses, and eukaryotic microbes are rarely reported (Table 1) 8,110,111,112
