Noxious nanotech: Water-borne nanomaterials promote multidrug-resistance gene transfer
Biomimetic nanosponges absorb toxins released by bacterial infections and venom
Engineers at the University of California, San Diego have invented a "nanosponge" capable of safely removing a broad class of dangerous toxins from the bloodstream – including toxins produced by MRSA, E. co ...
Human, soil bacteria swap antibiotic-resistance genes: study
Soil bacteria and bacteria that cause human diseases have recently swapped at least seven antibiotic-resistance genes, researchers at Washington University School of Medicine in St. Louis report Aug. 31 in Science.
Resistance to antibiotics is ancient: study
Scientists were surprised at how fast bacteria developed resistance to the miracle antibiotic drugs when they were developed less than a century ago. Now scientists at McMaster University have found that resistance has been ...
Bacteria develop restraint for survival in a rock-paper-scissors community
It is a common perception that bigger, stronger, faster organisms have a distinct advantage for long-term survival when competing with other organisms in a given community.
Attacking MRSA with metals from antibacterial clays
In the race to protect society from infectious microbes, the bugs are outrunning us. The need for new therapeutic agents is acute, given the emergence of novel pathogens as well as old foes bearing heightened antibiotic resistance.
Receptor proteins could hold clues to antibiotic resistance in MRSA
Scientists at Imperial College London have identified four new proteins that act as receptors for an essential signalling molecule in bacteria such as MRSA.
Humans passing drug resistance to animals in protected Africa, study says
A team of Virginia Tech researchers has discovered that humans are passing antibiotic resistance to wildlife, especially in protected areas where numbers of humans are limited. In the case of banded mongoose ...
Bacteria evolve resistance more quickly when stronger antibiotics are used
New scientific research published today in the journal PLoS Biology shows that bacteria can evolve resistance more quickly when stronger antibiotics are used.
Resurrection of 3-billion-year-old antibiotic-resistance proteins
Scientists are reporting "laboratory resurrections" of several 2-3-billion-year-old proteins that are ancient ancestors of the enzymes that enable today's antibiotic-resistant bacteria to shrug off huge doses ...
'Stressed' bacteria become resistant to antibiotics
Bacteria become resistant to antibiotics when stressed, finds research published in BioMed Central's open access journal BMC Evolutionary Biology. In particular E. coli grown at high temperatures become resistant to rifampicin ...
Scientists unveil secrets of important natural antibiotic dermcidin
An international team of scientists has discovered how an important natural antibiotic called dermcidin, produced by our skin when we sweat, is a highly efficient tool to fight tuberculosis germs and other dangerous bugs.
Manuka honey opens door for effective treatment of chronic wounds
Manuka honey is highly effective in the treatment of chronic wound infections, according to new UTS research into how honey affects the growth of bacteria.
New tool for mining bacterial genome for novel drugs
Vanderbilt biochemists have discovered that the process bacteria undergo when they become drug resistant can act as a powerful tool for drug discovery.
