Changes of bacterial counts from rectal biopsies (means): comparisons with the initial sample. The Enterobacteriaceae (Ent) species show a 10-fold increase in mean values in the control (-C) group while Lactobacillus (Lac) decrease 10-fold. In contrast, in the treatment group (-Lp) Lactobacillus (Lac) increase and Enterobacteriaceae decrease. Sulphite reducing clostridia (Cl) decrease in the control group. cfu, colony-forming units.
