Latest studies showed that bacteria-infecting viruses called bacteriophages, or simply phages, could kill different strains of the bacterium E. coli by making mutations in a viral protein that bound to host cells.
Researchers have shown that antimicrobial-resistant infections are rapidly increasing in animals in low and middle income countries. They produced the first global of resistance rates, and identified regions where interventions are urgently needed.
North America, Western Europe, Australia and New Zealand generally have the lowest levels of antimicrobial resistance, while Asia, Africa and South America have the highest levels.
A drug known as colistin is still being used as a growth promoter in animals. Colistin is classified by the World Health Organization as antibiotic that should only be used to treat infections when everything else has failed.
A team of US biologists has discovered thousands of four- and five-drug combinations of antibiotics that are more effective at killing harmful bacteria than the prevailing views suggested.
US researchers report that dietary iron supplements help to survive a normally lethal bacterial infection and resulted in later generations of those bacteria being less virulent.
Each year, farmers in the U.S. purchase tens of millions of pounds of antibiotics that are approved for use in cows, pigs, fowl and other livestock.
The research led to the identification of two synthetic retinoids, both of which demonstrated the ability to kill MRSA (methicillin-resistant Staphylococcus aureus), a type of staph bacteria that is resistant to several antibiotics.
Antibiotics could become nearly useless by mid-century against intense infections due to bacteria evolving antibiotic resistance. It's time to develop alternatives to antibiotics for small infections.
The new discovery shows promise in helping to treat the millions infected each year with antibiotic-resistant superbugs.
Teams of scientists are now working on a truly creative strategy: a pill carrying the genome-editing power tool CRISPR that instructs harmful bacteria to shred their own genes to bits.
Now, researchers in Cleveland, Ohio have taken a significant step toward defeating antibiotic-resistant infections by combining two different antibiotics that each block a different kind of drug-destroying enzyme secreted by bacteria.
