From: Comparing microbiotas in the upper aerodigestive and lower respiratory tracts of lambs
PCOA graph showing the relatedness of upper aerodigestive tract samples from lambs partitioned into two groups using the Laplace approximation. Lung fluids belonging to the same animals were partitioned into the same groups. Lung fluid partitions clustered significantly separately by AMOVA (PÂ =Â 0.016) as did oropharyngeal swabs (PÂ <Â 0.001). Controls are PBS and extraction kit reagent controls
