Which isn't the point I'm making. Topical treatments for a few genus of bacteria are _not_ a viable alternative

  If you can kill many (not only some - don't know where you get that info?) bacteria, fungi etc. during an operation, while they are on their way to infect a wound, how is this not viable? I think we are misunderstanding each other. Here is another article where infected burn wounds were "disinfected" with blue light: https://newatlas.com/blue-light-kills-bacteria/26026/ https://newatlas.com/blue-light-kills-bacteria/26026/ "In a proof-of-concept study, led by Dr. Michael R. Hamblin of Massachusetts General Hospital and Harvard Medical School, an array of blue LEDs was used to treat infected burns on lab mice. More specifically, the blue light was used to selectively eradicate potentially-lethal Pseudomonas aeruginosa bacteria in the animals’ skin and soft tissues. The results of the study were promising. All of the light-treated mice survived, while 82 percent of the untreated control group died. Additionally, unlike bacteria-killing ultraviolet light, the blue light wasn’t harmful to the animals’ own cells."

    So you're saying just have blue lights on in the OR for added protection? Because surgeons are still going to use sterile technique, chlorhexdine, and Ancef prophylaxis. If blue light helps in a couple trials, they'll add the blue light. Maybe it'll kill those few extra aerosolized bacteria or something

      Exactly, that's what my original comment said. Use it on the wound area before sewing the wound up. Or why not during the whole process.

    You are missing the point, this is a _topical_ treatment. Also, it appears to require a long, large exposure. Similally it can be equally as effective to use listerene to wash the wound. Yes it is promising, but its not a golden bullet and will not replace antibiotics. > not only some - don't know where you get that info? I got it from the paper you linked: Leuconostoc mesenteroides (LM), Bacillus atrophaeus (BA) or Pseudomonas aeruginosa (PA)

      This is to be used to prevent cases so antibiotics don't have to be used for a secondary infection.
