Metagenome of non-human tissue in bronchoalveolar lavage fluid
DNA or RNA samples were extracted from BALF and used for library construction.  The RNA was further subjected to reverse transcription into cDNA.  Following extraction, sequencing libraries were constructed by fragmentation, end repair, adapter ligation, and PCR amplification.  Next, sequencing was performed on MGISEQ-2082 (BGI China) to generate raw reads.
