Mycobacterium research and diagnosis

In thirty-eight dogs, after metabolic and bacteriologic studies were performed, 50 per cent of the small bowel including the ileocecal valve was excised. Thirty days later, repeat metabolic and bacteriologic studies were performed just prior to the creation of three different sphincter substitutes in some of the dogs: reversed segment (eight dogs); triple resection of longitudinal muscle only (eight dogs); and resection of both muscle layers (six dogs). The studies were performed again thirty days later. Reversed segments, while increasing transit time, do not improve absorptive deficits and worsen bacteriologic contamination of the remaining small bowel. Both muscle resection technics improve absorption concomitant with sterilization of the upper small intestine and greatly reducing the bacterial flora throughout the small bowel.
