Fig. 4From: Longitudinal assessment of the bovine ocular bacterial community dynamics in calvesPrincipal Coordinate analysis (PCoA) demonstrating microbial community differences before and after ulcer formation. A significant difference in community composition was detected when samples before infection and after ulcer formation was analyzed. The PCoA was performed using a weighted UniFrac distance matrix.
