I know, everytime I see a bottle of antibacterial hand-soap, dish soap, or the new ethanol gel giant Purell
TM I just gotta shake my head.
Mechanical abrasion is the most effective antibacterial process known. Elbow grease people, good old fashioned elbow grease. Well, then there's heat too I guess. I'm not aware of any thermophilic human pathogens yet. It's the psychrophilic ones that are a threat
I have observed
Pseudomonas aeruginosa survive without external nourishment on bare steel under 95:5 ethanol:water for seven days. They might have lived longer but I needed the steel back and had to clean them off. It's all in the biofilm slime (snot) they produce to protect themselves. (Listeria on meat packing gear anyone?)
So what's that Purell
TM good for again? Oh right, increasing demand for ethanol at a really bad time. (I expect significantly considering the proliferation of these pumps... I wonder if they are denatured or will the street people drink it like they used to do lysol?...) Lots of plain soap, hot water and some time with a fresh scrubbrush will be much more effective and environmentally friendly.
That said, I have a theory that continual exposure to low levels of bacteria maintains a healthy immune system (within reason), and that minimising exposure to anti-bacterial agents both reduces the chances of producing resistant strains and allows beneficial symbiotic bacteria to party on unhindered in natural competitive cycles.
The trend that I have observed in medicine is to over prescribe antibiotics, but under prescribe them at the same time. By this I mean they are prescribed too often but in insufficient amounts for too short a time, producing the optimum conditions for the production of resistant strains. Save em for when it really counts, and then don't scrimp on it. At least 1.5 grams of penicillin equivalent per day for at least ten days. None of this 500-750mg per day for 5 to seven days of less effective analogues... that is what got us here.
