Artificial intelligence yields new antibiotic

Using a machine-learning algorithm, MIT researchers have identified a powerful new antibiotic compound. In laboratory tests, the drug killed many of the world's most problematic disease-causing bacteria, including some strains ...

Antibiotic-resistance in Tanzania is an environmental problem

Antibiotic-resistant bacteria are prevalent in people, wildlife and the water in northeastern Tanzania, but it's not antibiotic use alone driving resistance. Instead, researchers at Washington State University found transmission ...

Color-changing bandages sense and treat bacterial infections

According to the World Health Organization, antibiotic resistance is one of the biggest threats to global health. Sensing and treating bacterial infections earlier could help improve patients' recovery, as well curb the spread ...

New portable tool analyzes microbes in the environment

Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms—too tiny to be seen by the naked eye—and their response to threats to their ecosystems.

Antibiotic resistance

Antibiotic resistance is the ability of a microorganism to withstand the effects of antibiotics. It is a specific type of drug resistance. Antibiotic resistance evolves via natural selection acting upon random mutation, but it can also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange. If a bacterium carries several resistance genes, it is called multiresistant or, informally, a superbug. The term antimicrobial resistance is sometimes used to explicitly encompass organisms other than bacteria.

Antibiotic resistance can also be introduced artificially into a microorganism through transformation protocols. This can aid in implanting artificial genes into the microorganism. If the resistance gene is linked with the gene to be implanted, the antibiotic can be used to kill off organisms that lack the new gene.
