The limits to this diagnostic approach are the examination duration, contamination of the sampling probe, the difficulty of demonstrating anaerobes, the quality of bacterial counts and in vitro cultures and, lastly, the sampling site compared to the seat of overgrowth. The result of this is false negatives and false positives. Coprocultures, unless they isolate a abundant monomorphic flora such as a particular strain of pathogenic enterobacteria, are of limited interest. The methods are limited by the use of stable or radioactive isotopes, the effect of the caecum, and acceleration of transit resulting from a dose of lactulose. Moreover, not all bacteria produce hydrogen.
Human milk stimulates motricity and provides bacteriostatic factors.
Antibiotic treatment depends on various strategies which will depend on habits, experience, anatomical or functional indication, as well as the germs involved. This is often the most effective stand, but means a total DD lasting according to aetiology and continuation of the systemic antibiotic treatment. Digestive mucus modifiers could be a useful therapeutic approach because of their capacity to intervene in bacterial adhesion mechanisms. The interactive mechanisms between mucin and bacteria are said to let the latter resist the binding and penetration of micro-organisms and toxins present in the intestinal lumen. Index de la page .
