A special issue on sepsis has been released by the publisher Landes Bioscience (Austin, TX USA). The articles contained in this special issue of the journal Virulence have been authored by world-class investigators and provide new insights into both the pathogen-related factors and the host defense mechanisms that lead to septic shock and contribute to its resolution or fatal outcome. Sepsis, or septic shock, is an excessive inflammatory response in answer to a serious infection, most...

Disruption of key cellular functions produces physiologic and behavioral responses Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of...

Babies and toddlers with congenital heart disease are at an increased risk of having harmful toxins in their blood, particularly following surgery, according to research by a team at Imperial College London. The study, published today in the American Journal of Respiratory and Critical Care Medicine, found that children with high levels of toxins from gut bacteria in their blood are likely to take longer to recover from surgery and spend more time in intensive care. The researchers say...

The zeta toxins are a family of proteins that are normally present within various pathogenic bacteria and can mysteriously trigger suicide when the cells undergo stress. A team led by Anton Meinhart at the Max Planck Institute for Medical Research in Heidelberg has now found the mechanism underlying this programmed bacterial cell death. Their paper, publishing next week in the online, open access journal PLoS Biology, reports that zeta toxins convert a compound required for bacterial cell...

Scientists from the National Institutes of Health and University of Chicago have found a promising treatment method that in laboratory mice reduces the severity of skin and soft-tissue damage caused by USA300, the leading cause of community-associated Staphylococcus aureus infections in the United States. By neutralizing a key toxin associated with the bacteria, they found they could greatly reduce the damaging effects of the infection on skin and soft tissue. Community strains of S....

By Amy Norton NEW YORK (Reuters Health) - Exposure to bacterial toxins may cause flu-like symptoms, breathing problems and skin reactions in some workers at sewage treatment plants, a study has found. Researchers in the Netherlands found that workers at 67 sewage treatment plants had heightened risks of daily cough, shortness of breath, skin rash and flu-like symptoms such as headache and body aches and pains. The culprit, say the researchers, seems to be the toxins that are...
