PCA plot showing differences in tonsillar microbiota composition by age. Arrows show ASVs driving the separation; samples in the direction the arrow is pointing have higher abundance of that ASV. Each point represents a sample. At the first timepoint (week 0), the tonsillar microbiota was characterised by a high abundance of Neisseria and Porphyromonas ASVs, while post-weaning samples (week 5) had a high abundance of Streptococcus porcorum
