Fig. 1From: Piglet nasal microbiota at weaning may influence the development of Glässer’s disease during the rearing periodNasal microbiota of piglets from farms with Glässer’s disease (GD) and control farms (C). The mean relative abundance (%) of OTUs found in nasal swabs of 3–4 weeks-old piglets is presented. Samples were analyzed altogether (Total), or were grouped based on the health status (C and GD). Each graph represents the OTUs at different taxonomical levels: phylum (a), family (b), genus (c). Results from individual farms are presented in Additional file 1 Back to article page
