Colonic lymphoid aggregates in patients without colonic pathology and normal colonoscopic findings have been associated with persistent diarrhoea in a subset of patients. These lymphoid aggregates are not consistently reported by pathologists. We evaluated lymphoid aggregates in 40 symptomatic patients from otherwise normal colonic biopsies with normal colonoscopy findings to determine the relationship between clinical and pathologic parameters including any associations with normal colonic microbial flora. We found that the presence of gram-negative cocci, short bacilli and long bacilli were associated with larger more well-circumscribed lymphoid aggregates than other microbial flora combinations. For some patients, specific colonic microbial flora content may be associated with lymphoid response and symptoms.
