Lactobacilli are known to fortify epithelial barrier by various mechanism such as induction of mucin secretion, enhancement of tight-junction functioning, upregulation https://www.selleckchem.com/products/lcl161.html of cytoprotective heat shock proteins and prevention of apoptosis of epithelial cells [38]. Probiotic strains of Lactobacillus are known to prevent infectious diarrhea, antibiotic associated diarrhea and diarrhea in children who are unusually more susceptible as a result of poor nutrition, impaired immune status or frequent exposure to pathogens [39]. We observed significant

decrease in population of Lactobacillus in gut flora of E. histolytica positive patients as compared to that of healthy individuals that support our earlier observation made by semi quantitative method [1]. Methanobrevibacter smithii is the dominant archaeon in human gut that affects the specificity and efficiency of bacterial digestion of dietary polysaccharides, thereby influencing host calorie harvest and adiposity [40]. It has been suggested that the low and variable prevalence of Methanobrevibacter smithii and Methanosphaera stadtmanae DNA in human stool contrasts with the paramount role of these methanogenic archaea in digestion

processes and hypothesized that this contrast is a consequence of the inefficiencies of current protocols Defactinib order for archaea DNA extraction [41]. In our samples prevalence of M. smithii in healthy individuals stool samples was 27.27 % and that was further reduced

to 11.7 % in E. histolytica positive samples. Real-time analysis shows Sulfite dehydrogenase no significant alteration in population of M. smithii. Variation in the loads of M. smithii under different pathophysiological condition such as during amebiasis has not been reported so far. Suphate reducing bacteria (SRB) are a group of non spore forming, gram negative, dissimilatory sulphate reducing, anaerobic bacteria. SRB can be isolated from the intestinal tract of humans and various environmental sources. Intestinal SRB’s growth and resultant hydrogen sulfide production have been implicated to damage the gastrointestinal tract and thereby contribute to chronic intestinal disorders [42]. Desulfovibrio fairfieldensis and D. desulfuricans have been associated with incidence of bacteremia and D. vulgaris has been associated with intra-abdominal infections [43]. The prevalence of Sulphate reducing bacteria was 36.36% in healthy and 11.7% in amoebic individuals stool samples. However, the change was not statistically significant. The genus GDC 973 Campylobacter is notorious for causing gastroenritis by C. jejuni but uncultured Campylobacter species e.g. Campylobacter hominis whose role is not clear yet, do exist in lower gastrointestinal tract of healthy humans [44]. We observed significant decrease in population of Campylobacter in E. histolytica positive individual as compared to healthy individuals.
