Search for new antibiotics advanced by discovery of key processes within bacterial protein - 0 views

  •  
    Scientists have recently discovered how pili are formed, giving another potential target for antimicrobial medications
  •  
    A rather novel discovery in the field of pili biogenesis. This also appears to be a big steeping stone in the development of potential new antibiotics for cystitis (bladder inflammation a.k.a urinary tract infections).

Drugs to Fight Deadly Superbugs in Short Supply - 0 views

  •  
    With antibiotic resistance looming, the failure of drug companies to develop new drugs to fight gram-negative bacteria could potentially lead to millions of deaths just from a common cold or from the flu. Drug companies cannot turn out new antimicrobials fast enough, and the ones that they do get out to the public cost billions of dollars.

    Scary to think that we're all at risk!

Discovery of wound-healing genes in flies could mitigate human skin ailments - 0 views

  • key to their technique was the use of trypsin, a member of a family of enzymes called serine proteases, which activates genes involved in wound healing
  • incorporating specific, regulated series proteases and antimicrobial peptides at the sites of diabetic ulcers or skin grafts for more efficient wound healing
  •  
    A specific approach to target the genes that are involved in wound healing seems like a progressive approach for several skin disorders.

Foodborne urinary tract infections: a new paradigm for anti-microbial resistant foodbor... - 0 views

  •  
    E. coli has been known to cause G.I tract infections for a long time, but now studies have been finding the same strain in the urinary tract as well. This is leading to a progressive antimicrobial resistance that is combining the effects of increased UTI antibiotic usage and agricultural antibiotic use against the same strain of E. coli.

Comparison of Single and Combination Antimicrobial Agents for Prevention of Experimenta... - 0 views

  •  
    The main therapy of Gas Gangrene is amputation even before systemic infection, hyperbaric oxygen, or penicillin treatment therapy. Combination therapies were tested on mice with Gas Gangrene, which proved that metronidazole and penicillin together produced a higher mortality rate than that of metronidazole alone. But, metronidazole and clindamycin were more effective than penicillin alone. So some combination therapies are effective, while others are more dangerous.

Photodynamic therapy for Staphylococcus aureus infected burn wounds in mice - 0 views

  • The growing resistance of pathogenic microorganisms against antimicrobial agents has generated a search for alternative treatments for localized infections.
  • In this study we have demonstrated that it is possible to rapidly photoinactivate S. aureus when present in a burn wound with PTMPP as PS

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

    Although nanosilver has effective antimicrobial properties against certain pathogens, it can cause other potentially harmful organisms to rapidly adapt and flourish, a new study reveal...Hmmm!!

Antiseptics Used to Prevent Health Care Infections Might Cause Them. Oops. | Wired Scie... - 0 views

  • pre-operative antiseptics have never been examined for infection risk. They were grandfathered into FDA approval because they were on the market long before the FDA began assessing such products, as a result of expert testimony that they would kill any microbes that contaminated them.  That assumption turns out to have been incorrect.
