Unnecessary testing for UTIs cut by nearly half

Tests to detect urinary tract infections (UTI) often are performed routinely in hospitals, even when patients don't have symptoms. Such testing "just to be safe" can return results that lead doctors to prescribe antibiotics ...

Cocktail of common antibiotics can fight resistant E. coli

Today, many disease-causing bacteria acquire resistance genes, which make antibiotic treatment ineffective. One gene especially—CTX-M-15, encoding an extended spectrum beta-lactamase (ESBL)—can lead to resistance in E. ...

Cleaning routine shows promise in curbing superbug infection

Think of it as decontaminating yourself. Hospitalized patients who harbor certain superbugs can cut their risk of developing full-blown infections if they swab medicated goo in their nose and use special soap and mouthwash ...

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.
