Using surface disinfectants may contribute to bacterial antibiotic resistance, according to new research in January’s issue of Microbiology. We already know that the use of consumer-grade antimicrobial hand soaps contribute to the rise of antibiotic resistance. Similarly, the study demonstrated that when non-lethal amounts of disinfectant were added to bacteria in culture, the adapted bacteria were more likely to survive compared to the non-adapted bacteria. “In principle this means that residue from incorrectly diluted disinfectants left on hospital surfaces could promote the growth of antibiotic-resistant bacteria,” said Dr. Gerard Fleming who led the study. Bacteria that can resist both surface disinfectants and antibiotics could pose a very serious health concern to not only hospitalized patients, but the general public as well. [via Science Daily]

Why aren’t we motoring what the hospital’s are cleaning with more closely. It seems to me we would have less sick people if we would change our way of informing the public of ways to fight off germs.

I APPRECIATE the findings of Dr Flemming and colleagues;my worry and question ,is what should be the new approach to antseptic preparation of both the the surgeon and the patient for a surgicalprocedure?
