Antibiotic Resistance: Wastewater treatment may be creating antibiotic resistance ♦ Vulnerability found in some drug-resistant bacteria ♦ Drug resistant strain of typhoid spreading

New chip makes testing for antibiotic-resistant bacteria faster, easier Now, researchers have designed a diagnostic chip to reduce testing time of antibiotics from days to one hour, allowing doctors to pick the right antibiotic the first time
Genomic data reveals emergence in Africa of drug resistant strain of typhoid The emergence of a novel strain of Typhoid fever in Malawi,The H58-strain, which is likely to have emerged in Asia approximately thirty years ago, is now rapidly spreading across Africa, where it has been introduced on several separate occasions. This strain appears to be its ability to acquire resistance to commonly available antibiotics
New online tool to predict genetic resistance to tuberculosis drugs A new TB-Profiler tool analyses and interprets genome sequence data to predict resistance to 11 drugs used to fight TB. This tool finds which drugs to use for a patient with TB can be sped up by days or even weeks, increasing the likelihood of a cure.
Vulnerability found in some drug-resistant bacteria Analyzing the physical dynamics of all currently mapped structures in an important group of antibiotic-destroying enzymes has found a common structural feature. The apparently universal nature of this complex structural dynamic implies that it is critical to the antibiotic destroying properties of the enzyme and points to the possibility of finding a way to chemically disable the enzymes and bacterial antibiotic resistance.
Wastewater treatment may be creating new antibiotics Scientists have been aware of the potential problems of antibiotics being present in wastewater, and new research is showing that treatments to clean wastewater may actually be creating new antibiotics and further contributing to the development of antibiotic resistance in the environment
