Multiple antibiotic resistance is auxiliary to bacterial fitness and adaptability, study shows

Could a gene regulatory network in gut microbes have evolved its elaborate and tightly regulated molecular machinery only to pump out antibiotics indiscriminately? Researchers from the Institute of Science and Technology Austria (ISTA) show this is an auxiliary function. By maintaining basal levels of genetic activity when the network is in its OFF state, these genes ensure the bacteria remain fit and adaptable to their highly variable environme…
