biofilm

It's much more than an herbicide, the impact is on the metabolisms of the biofilm organisms.

At no point do they ever show meaningful growth of biofilm on a washed cutting board allowed to dry.

Cholesterol -> Coronary plaque -> Dormant bacteria within the plague biofilm is shielded from the immune system and antibiotics.

So why not start by trying to cover every rock in this system with a biofilm just one cell thick?

Current methods of biofilm dispersal are application of strong acids and bases or an autoclave.

Assessing Salmonella enterica biofilm formation in frequent scenarios of chicken handling in domestic kitchen environments.

This could be a biofilm or otherwise dormant bacteria as described in the article.

One reason is that the antibiotics can't reach the bacteria -- for example if the bacteria are organized into an abscess or biofilm.

Cross-contamination and biofilm formation by Salmonella enterica serovar Enteritidis on various cutting boards.

Some more information here on biofilm development and sepsis/mortality rates which is chilling.

This may tie into a link I posted recently from a Finnish study linking biofilm rupture to heart attacks.

I agree about the importance of the biofilm claim, but what they don't explain is how they actually achieve this.

Moving on: > "Formation and quantification of biofilm.

On the contrary, all cucumber samples were contaminated with Salmonella Enteritidis, even after washing the cutting surface in the presence of biofilm [emphasis mine]" So in one case (salmonella without biofilm) wood looks worse with marginal significance, but in all cases where the salmonella is biofilm-producing, it doesn't matter what the board is made of.

Biofilm also generally takes days or 24 hours minimum to form, and requires constant moisture, so claims that any kind of cutting board develop "more biofilm" are immediately suspect as well, and clearly do not reflect any kind of sane real-world usage.

A headline like "Biofilm-inhibiting bacteria may provide an alternative to brushing your teeth" conveys much more information about the content (and doesn't break that "law", either).

Biofilm lets pathogens prosper while hiding them from diagnosis.
