(A) Three‐color fluorescence in situ hybridization (FISH) of Bacteroides spp. identified in ileal biopsies of a cat with small cell GI LSA. Cy‐3‐labeled Bacteroides spp. (labeled orange) localized within adherent mucus of an ileal biopsy specimen. The mucus is also occupied by other bacteria (total bacteria labeled green with FITC‐Eub). The dark blue structures are epithelial cell nuclei stained with DAPI. (B) Three‐color fluorescence in situ hybridization (FISH) of Bacteroides spp. identified in ileal biopsies of a cat with IBD. Cy‐3‐labeled Bacteroides spp. (labeled orange) localized within adherent mucus of an ileal biopsy specimen. The mucus is also occupied by other bacteria (total bacteria labeled green with FITC‐Eub). The dark blue structures are epithelial cell nuclei stained with DAPI
