How To Kill Flesh-Eating Bacteria. (S. pyogenes)

It occurred to me that people talk about killing flesh-eating bacteria, but in many parts of the world asking for Cipro or a third-generation Cephalosporin isn’t really an option.  Even in situations where you get to an E.R., if they don’t take off the tissue within 24 hrs, you’re in trouble. 

So here’s a short list of things that kill Steptococcus pyogenes, the most common flesh-eating bacteria.  The poor girl who has it right now has a fresh water variant, which just involves not deeply lacerating yourself in fresh water and then having E.R. doctors who consider it a possibility rather than assuming you’re a whiner.

To kill Steptococcus “flesh-eating” pyogenes:

Antibiotics:  good ol’penicillin.  Preferable over many of the newer antibiotics.  “All isolates were sensitive to penicillin, cefradine, and ofloxacin.”

Antimicrobial efficacy of Achillea ligustica All. (Asteraceae) essential oils against reference and isolated oral microorganisms.

The aim of this study was to verify the effectiveness of Achillea ligustica essential oils against several oral microorganisms in comparison with a commercial essential oil-containing mouthrinse (Listerine(®)) and clove oil (containing 89% eugenol). The inhibition efficacy of A. ligustica essential oils alone and in combination with Listerine(®) was evaluated by the micro-dilution method. The most susceptible microorganisms were Bacillus cereus, Streptococcus pyogenes, and Candida albicans. The efficacy was similar to that of the clove oil. The antiseptic mouthwash Listerine(®) did not exert a strong inhibition on microbial strains tested, whereas its effectiveness increased significantly when essential oil was added. The study provides additional evidence for the in vitro inhibitory activity of A. ligustica essential oils on several pathogens, suggesting their usefulness in mouthrinse formulations as an adjunct to mechanical oral hygiene regimens. Essential oil-containing mouthrinses can be beneficial, safe components of daily oral health routines, representing an efficient and without side effect alternative to prevent and control oral infections.

  1. It’s crazy, the things you can read on the internet. I don’t mean that in a bad way. I mean, who would have thought I would ever have read an article on how to kill flesh-eating bacteria. I am constantly stumbling upon fascinating new topics on WordPress.
    I hope you don’t mind that this comment isn’t related to the subject of your post.

  2. Not at all. I think we all need to expand our horizons.

  3. […] had previously written about how to kill flesh-eating bacteria, which should be susceptible to antibiotics. So now I’d like to delve a bit deeper into this […]
