Bacteroides ovatus is an obligately anaerobic, non-spore-forming Gram-negative rod in the family Bacteroidaceae, and one of the most abundant Bacteroides species in the human colon. It plays a key role in the degradation of complex dietary polysaccharides, particularly xylans and pectins, contributing to short-chain fatty acid production and cross-feeding interactions within the gut microbial community. B. ovatus encodes a large number of polysaccharide utilisation loci and carbohydrate-active enzymes, and has been shown to promote immune homeostasis through the induction of regulatory T cells via specific capsular polysaccharides.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
