"Bleach and phenolics have been used since the 1800s, and quaternary
ammonium compounds since at least 1935. The many decades and high
volumes of use have provided ample op****tunity for bacteria to adapt
genetically; however, disinfectant failure due to genetic adaptation
has not been re****ted. In contrast, the evolution of
antibiotic-resistant bacteria rendered penicillin therapeutically
useless within a decade of its introduction. In addition, germicides
have been shown to be equally effective against antibiotic-resistant
bacterial strains (e.g., MRSA, VRE, PRSP) and strains exhibiting
renewed virulence (e.g., E. coli 0157). Biocides are crucial to
reducing the reservoir of such pathogens in our surroundings."
"By definition, antibiotics are substances produced by one organism
that inhibit the growth of another organism. They have specific
cellular targets, e.g., a particular site on an enzyme, into which they
fit like a key into a lock to perform their function. Just as minor
changes in a lock make a key useless, a single mutation in an organism
can make it resistant to an antibiotic. Penicillin is a good example.
Widespread use began circa 1945, and resistance was detected within a
decade. Conversely, many antiseptics and disinfectants have been used
for over 100 years without loss of effectiveness."
As usual, Rod Speed is talking out of his germ infected ass and
provides no proof for his claim. He's a confused, old welfare bum who
hasn't a clue, as always.
