    Many studies are currently being done on the mutualistic affects of nematodes on humans. This study could potentially help the vast obesity epidemic.

  • gut microbiota differs at the phylum level depending on weight status
  • human obesity is associated with a low abundance of intestinal Bacteroidetes and high abundance of Firmicutes
  • The mere presence of gut microbiota has recently been shown to contribute to obesity

    With the further studies in ratios of gut microbes found in people of varying weights, there are different treatments also being performed on people that undergo bypass surgery to alter the gut microbes to sustain weight loss.

    Read an article on a fermentation guru (http://www.nytimes.com/2012/09/19/dining/fermentation-guru-helps-chefs-find-new-flavors.html?pagewanted=2&ref=microbiology), so was interested in finding an article on fermentation and found this article on the fermentation of wine mixing species of yeasts and the benefits. The use of a multistarter fermentation process with S. cerevisiae and non-Saccharomyces wine yeasts has been proposed to simulate natural must fermentation and to confer greater complexity and specificity to wine. The advantage of this process is to simulate a spontaneous process avoiding the risks of stuck fermentation. Furthermore, non-Saccharomyces wine strains could have some specific enological characteristics that are absent in S. cerevisiae species, leading to combined, synergic and/or additive effects on the final wine.

Discovery holds potential in destroying drug-resistant bacteria - 0 views

  • Dr. Montelaro and his colleagues found that a particular sequence of amino acids on the tail end of HIV allow the virus to "punch into" and infect cells. The team manufactured a synthetic and more efficient version of this sequence -- called engineered cationic antimicrobial peptides, or "eCAPs" -- that laboratory tests have shown to rapidly destroy bacteria that are otherwise resistant to most standard antibiotics.
  • Traditional antibiotics typically work by poisoning important metabolic processes after being taken up by the target bacteria, a process that may take hours, or days, to clear a bacterial infection. In contrast, the eCAPs are specifically attracted to the surface of target bacteria where they disrupt the bacterial membrane, causing death within seconds, or minutes.
  • eCAPs work well against biofilms

    very interesting...the same mechanism HIV uses to infect cells can be manufactured and used to destroy antibiotic-resistant bacteria
