Possibility of Ideal Intestinal Remedy

I’m not able to keep intestinal condition without remedy which is prepared by Lactobacillus, Bifidobacterium, Lactococcus, and others. Eating yogurt is also okay for this purpose, ad personam I prefer to take these bacterial tablets and believe more effects. However, many people know these effects of current intestinal remedies are mild not fast-acting properties.

Several reports mentioned that intestinal bacterial flora and its regulation were not simple. It is starting discussion that natural immunity may regulate intestinal flora; e.g. antibacterial peptide α-defensins which is secreted from paneth cells on small-intestinal epithelium could regulate flora distribution (Salzman et al., 2010; Matsuda et al., 2011). By contrary, very simple strategy is reported as following: Clostridium difficile brings bad diarrhea that was resistant to antibiotic. Van Nood and co-workers (2013) injected healthy person’s feces into patient’s guts, and its curative effect was so good surprisingly, but we cannot call it a remedy!

Two NGS platforms, GS FLX/Junior and MiSeq, can perform distributional analysis via deep sequencing of 16S-rRNA amplicons. But it is still difficult for both platforms to do metagenome assembling for getting whole gene information in flora, because their read length is not long enough to make reliable contigs without chimeras between different bacteria one another. Therefore I strongly expect that super long read platforms including PacBio RS series and coming nano-pore technologies will break current limitations and will contribute to develop ideal intestinal remedy for my instable stomach.
