Adherence potential of indigenous lactic acid bacterial isolates obtained from fermented foods of Western Himalayas to intestinal epithelial Caco-2 and HT-29 cell lines.

The adherence of bacteria to epithelial cells and mucosal surfaces is a prerequisite for their colonization in the gut and a key criterion for the selection of probiotics. In this study, the eleven indigenous lactic acid bacterial isolates obtained from traditional fermented foods of Western Himalayas were screened for their adherence potential to intestinal epithelial cell lines. The level of adherence of eleven indigenous isolates to Caco-2 and HT-29 cell lines varied from 2.

Cyclooxygenase as a target in chemoprevention by probiotics during 1,2-dimethylhydrazine induced colon carcinogenesis in rats.

The present study was undertaken to assess the effects of potential probiotics in regulating the activity of cyclooxygenase-2 (COX-2) along with other morphological and histological analysis during 1,2-dimethylhydrazine (DMH) induced colon carcinogenesis in rats. The rats were divided into 6 groups viz., normal control, Lactobacillus plantarum (AdF10) treated, Lactobacillus rhamnosus GG (LGG) treated, DMH treated, AdF10 + DMH treated and LGG + DMH treated.
