Description
Bacterial overgrowth is a condition in which abnormally large numbers of bacteria (108 to 1010 organisms per gram of intestinal contents) colonize the lumen of the small intestine, having serious effects on small intestine function resulting in intermittent diarrhoea and sometimes weight loss. Bacteria involved include the anaerobic spp. Clostridia are the most important, but Bacteroides, Lactobacilli, Enterobacter and coliforms are also involved.
