A new study from Karolinska Institutet show that humans are able to smell sickness in someone whose immune system is highly active. This ability to smell health or disease occurred within just a few hours of exposure to a bacterial endotoxin.

Scientists at Karolinska Institutet have presented a new principle for fighting bacterial infections, in other words, a new type of antibiotic, in the FASEB Journal. The new antibiotic mechanism is based on selectively blocking the thioredoxin system in the cells, which is crucial to the growth of certain bacteria. Scientists hope to be able to treat such conditions as stomach ulcers, TB and MRSA.

For babies, the trip from the womb to the outside world is a transition from a blank, sterile slate to host for what will eventually be trillions of microscopic organisms. Unfortunately, the demographics of a burgeoning microbial community can easily tip in favor of dangerous bacteria.

Researchers from the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) have developed a new laboratory test that can rapidly identify the bacterium responsible for staph infections. This new test takes advantage of unique isotopic labeling combined with specific bacteriophage amplification to rapidly identify Staphylococcus aureus.

A key mechanism by which a bacterial pathogen causes the deadly tropical disease melioidosis has been discovered by an international team, including a University of Exeter scientist. The findings are published in the journal Science and show how a toxin produced by the bacterium Burkholderia pseudomallei kills cells by preventing protein synthesis.

Understanding how bacteria infect cells is crucial to preventing countless human diseases. In a recent breakthrough, scientists from the University of Bristol have discovered a new approach for studying molecules within their natural environment, opening the door to understanding the complexity of how bacteria infect people.
