Study of the intestinal microflora - The human digestive tracts and its microbiota (Module 4 - basic)

Topic I: “The intestinal flora” discusses the microbial population of the human digestive tract. This part also provides information concerning the quantitative and qualitative characterization of this ecosystem, the interaction between gut bacteria, intestine and host immunity. In particular, this topic explain the important role that the autochtonous microbiota, the normal microbiota and the potentially pathogens acquired plays for the health’s host. In Topic II. “Methods of analysis of intestinal flora” classical methodologies of isolation and identification were discussed. Also phenotypic and genotypic characterization of the microrganisms have been applied, as well as molecular techniques useful to identify and calculate the evolutionary relatedness between microbial strains.
