[Fungus colonization in colitis].
Fungal cultures, unstained smears and histological assessment of endoscopically obtained particles from ulcers in rectum, colon or terminal ileum were obtained in a prospective study of possible fungal infection in 78 patients with colitis of various aetiologies (Crohn's disease - 46; ulcerative colitis - 21; infectious colitis - 5; ischaemic colitis - 2; radiation colitis - 1; non-classifiable colitis - 3). Positive fungal culture was obtained in 13 patients (16.7%). The germ count was low (2--8 colonies per biopsy piece). The demonstrated fungi were almost exclusively Candida or Torulopsis. The potentially pathogenic mycelia phase of the fungi were never seen, either histologically or in unstained preparations. Stool specimens, obtained at the same time, were examined in 54 patients: positive cultures were obtained in 14 (25.9%). Only rarely were there concordance of positive fungal findings in both ulcer particles and faeces. It is concluded that (1) there is little danger of secondary fungal infection in colitis of various aetiologies; (2) positive faecal fungal culture is apparently of no pathogenic significance if the germ count is less than 10(6) per gram stool; (3) in the lower as well as the upper gastro-intestinal tract pathogenic fungal infection can be demonstrated only by endoscopy and biopsy.
