The research team focused on Pseudomonas aeruginosa, a bacterium responsible for a range of infections in people with weakened immune systems. When the scientists added increasing amounts of disinfectant to P. aeruginosa cultures, the bacteria adapted to survive not only the disinfectant but also the antibiotic called ciprofloxacin.
antibiotic-resistant bacteria are a growing problem. Over and improper use of antibacterials has been shown to produce antibiotic-resistant bacteria and now it seems disinfectants may be a culprit as well.
Before antibacterials an infection from even a small cut could have been fatal. Infections killed more people on battle fields than bullets, swards arrows and spears ever did. With the rise of antibiotic-resistant bacteria it could get that way again in the future.
We have lived with bacteria sense our ancestress where single-celled. We have an immune system to take of care invading bacteria and keep us healthy. The only bacteria you have to worry about are the ones that can actually kill us. Just clean your dishes with regular soap and water (no antibacterial soap) and watch your counter with regular cleanser. You don't need to sanitize everything.
