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]
