Antibiotics promote the growth of antibiotic-resistant bacteria in the gut
Antibiotic-resistant bacteria get extra nutrients and thrive when the drugs kill ‘good’ bacteria in the gut, a new study reveals.

News
New species of marine bacteria isolated from a deep-sea cold seep
Scientists have isolated a new species of marine bacteria that multiplies by a unique budding mechanism and releases viruses to facilitate nitrogen metabolism.

News
Cargo system inhibits E.coli biofilms with a fraction of the antibiotic dose
Scientists have designed a bacteria-targeted cargo system that is capable of inhibiting a quinolone resistant Escherichia coli biofilm using much lower levels of antibiotic. The researchers, from Koç University School of Medicine in collaboration with College of Science, Department of Chemistry, encapsulated the antibiotic ciprofloxacin into superparamagnetic iron oxide nanoparticles ...

News
Lifestyle changes while on antibiotics can help to fight AMR
Cooking food thoroughly and avoiding some types of vegetables and salad during a course of antibiotic treatment could potentially reduce antibiotic resistance, by preventing bacteria carrying resistance genes getting into the gut.

News
Oxygen charge can battle multidrug-resistant pathogens
Researchers have introduced a molecular singlet oxygen battery that can be ‘charged’ with reactive oxygen, which it then releases in deep tissue layers to target methicillin-resistant staphylococcus.
