Flu virus suppresses body's ability to defend against bacteria

When infected with influenza, the body becomes an easy target for bacteria. The flu virus alters the host's immune system and compromises its capacity to effectively fight off bacterial infections. Now, a team of immunologists at the Helmholtz Centre for Infection Research (HZI) and cooperation partners has discovered that an immune system molecule called TLR7 is partly to blame. The molecule recognizes the viral genome - and then signals scavenger cells of the immune system to ingest fewer bacteria.

Triclosan can contribute to increased risk of allergies in children

Triclosan - an antibacterial chemical found in toothpaste and other products - can contribute to an increased risk of allergy development in children. This comes from the Norwegian Environment and Childhood Asthma Study, in which the Norwegian Institute of Public Health is involved. Similar results are reported in the USA.

Paxvax PXVX0200 cholera vaccine demonstrates safety and immunogenicity in Phase 1 clinical trial

PaxVax Inc, which develops and commercializes innovative vaccines against infectious diseases in a socially responsible manner today announced results from a Phase 1 clinical trial of PaxVax's single-dose oral cholera vaccine candidate at the 2012 American Society of Tropical Medicine and Hygiene (ASTMH) Annual Meeting in Atlanta.

DNA sequencing helps detect MRSA outbreaks in hospitals

This study used DNA sequencing to examine an outbreak of MRSA in a hospital, to uncover new cases and, as the study developed, to intervene in the outbreak to end it more quickly. Sequencing illuminated each person infected and described the transmission of MRSA between people coming to the hospital and within the hospital.

Certain UTI-causing bacteria become more difficult to treat with current antibiotics

Certain types of bacteria responsible for causing urinary tract infections (UTIs), the second-most-common infection in the United States, are becoming more difficult to treat with current antibiotics, according to new research from Extending the Cure (ETC), a project of the Center for Disease Dynamics, Economics & Policy.

UCI study reveals novel immune system response to bacterial infections

UC Irvine biologists have discovered that fats within cells store a class of proteins with potent antibacterial activity, revealing a previously unknown type of immune system response that targets and kills bacterial infections.

Taste receptor governs respiratory infection susceptibility

The bitter taste receptor TAS2R38 may play a role in innate defense, say researchers, who have found that variations in the TAS2R38 gene may regulate susceptibility to respiratory infection.

New vaccines and drug treatments urgently needed for bacterial meningitis

New vaccines and drug treatments are urgently needed for bacterial meningitis, a devastating disease which kills or maims around a fifth of people who contract it, according to medical experts writing in a new Series on bacterial meningitis, published in The Lancet.

Scientists develop measures to prevent health problems associated with biogenic amines in wine

Biogenic amines may be one of the factors responsible for symptoms such as headaches, gastro-intestinal disorders, shortness of breath, fall in blood pressure, and even unconsciousness and cardiac arrhythmia in severe cases. Histamine, one of the best known members of this group, can cause serious physical problems. Biogenic amines can be produced in the body by natural metabolic activities but are also ingested in larger quantities with food.

Researchers discover cellular pathway that causes lung-damaging inflammation in CF

Vancouver researchers have discovered the cellular pathway that causes lung-damaging inflammation in cystic fibrosis (CF), and that reducing the pathway's activity also decreases inflammation.

Washington University, SRI investigators launch Global Metabolomic Initiative

Investigators at Washington University and The Scripps Research Institute have announced the launch of a "Global Metabolomic Initiative" to facilitate meta-analyses on studies of the metabolism of bacteria, yeast, plants, animals and people.

Elafin protein protects against inflammatory diseases

This protection is provided by a human protein, Elafin, which is artificially introduced into dairy produce bacteria (Lactococcus lactis and Lactobacillus casei). In time, this discovery could be useful for individuals suffering from chronic inflammatory diseases such as Crohn's disease or ulcerative colitis.

Researchers show how bacteria control processes in human cells

Bacteria can talk to each other via molecules they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers at Link-ping University in Sweden are showing how bacteria control processes in human cells the same way.
