System quickly spots antibiotic-resistant bacteria by watching them shimmy
If the bacteria with which someone is infected are antibiotic-resistant, physicians need to know so as soon as possible, so they can take the appropriate action. A simple new system could help, by detecting such resistance in just two hours as opposed to the usual 24.Ordinarily, in order to see if bacteria have developed a resistance to certain antibiotics, a population of the microbes has to be grown in a Petri dish to which the drugs are then added. It's also possible to perform a genetic analysis of the bacteria, to…
