Image of the colon of a mouse mono-colonized with Bacteroides fragilis (red) residing within the crypt channel. The red staining is due to an antibody to B. fragilis, the green staining is a general dye for the mouse cells (phalloidin, which stains F-actin) and the light blue glow is from a dye for visualizing the mouse cell nuclei (DAPI, which stains DNA). Bacteria from the human microbiome have evolved specific molecules to physically associate with host tissue, conferring resilience and stability during life-long colonization of the gut. Image is featured in October 2015 Biomedical Beat blog post Cool Images: A Halloween-Inspired Cell Collection.
