Fig. 1From: Relationship between nasopharyngeal and bronchoalveolar microbial communities in clinically healthy feedlot cattleRelative abundance of bacterial 16S rRNA gene sequences at the phylum level observed in the NPS a and BAL b samples from 8 healthy feedlot calves. Only those bacterial phyla that averaged more than 1% of the relative abundance across all samples when sequencing V3-V4 hypervariable regions are displayed. All other unassigned and classified OTUs belonged to phyla comprising less than 1% of the total abundance represented as others/UnassignedBack to article page
