Historically, this organism was among a group of enteric protozoan parasites beginning with Giardia duodenalis (previously G. lamblia) that were initially believed to be solely commensals and not capable of causing symptomatic illness. Commensal non-toxigenic Bacteroides fragilis confers powerful health benefits to the host, and has recently been identified as a promising probiotic candidate.

Epidemiology. In consideration of the capability of B.uniformis, B.fragilis, and, to a lesser extent, B.caccae to induce behavioral deficits, these results suggest that hippocampal 5-HT depletion may be a shared mechanism to predispose the onset of depression, explaining their distinction from B.ovatus in behavioral modulation.
