Drug Resistant Research: Gel filled with nanosponges cleans up MRSA infections ♦ Re-engineered antibiotic for treatment of drug-resistant bacteria ♦ antibiotic resistance detected in chicken meat

Gel filled with nanosponges cleans up MRSA infections Nanoengineers have developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This 'nanosponge-hydrogel' minimized the growth of skin lesions on mice infected with MRSA -- without the use of antibiotics.
Re-engineered antibiotic show potential for treatment of drug-resistant bacteria Scientists have developed a second-generation antibiotic that shows early effectiveness against common bacterial infections that pose a serious health threat to children and adults.
Bacteria cooperate to repair damaged siblings A certain type of soil bacteria can use their social behavior of outer membrane exchange to repair damaged cells and improve the fitness of the bacteria population as a whole. This is the first evidence that a bacterium can use cell-content sharing to repair damaged siblings.
Phages transducing antibiotic resistance detected in chicken meat Antimicrobial resistance in bacteria poses a global threat to public health. Common antibiotics are often ineffective in treating infectious diseases because pathogens acquire resistance genes.
