A novel approach for developing new antibiotics

Researchers at Children's Hospital of Philadelphia (CHOP) have developed a novel method for producing new antibiotics to combat resistant bacteria. Through an approach that would target bacteria with an antibiotic that is ...

A new avenue for fighting drug-resistant bacteria

A small regulatory RNA found in many problematic bacteria, including Escherichia coli, appears to be responsible for managing the response of these bacteria to environmental stresses. Professor Charles Dozois from Institut ...

Every mainland Australian state now allows GMO crops

On July 1, the New South Wales government will lift a ban on genetically modified (GM) crops after an 18-year moratorium. It will mean GM crops can now be grown in every Australian state except Tasmania.

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.
