Listeria News and Research

RSS

Listeria is a bacterial genus containing seven species. Named after the English pioneer of sterile surgery, Joseph Lister, Listeria species are Gram-positive bacilli and are typified by ''L. monocytogenes'', the causative agent of listeriosis.

Meningitis in Newborns: What to Look Out For

Claire is Evidence & Policy Manager at the UK and international charity Meningitis Research Foundation (MRF). She discusses the signs and symptoms of meningitis in newborns, and the aims for the recent diagnostic eTool developed by the MRF.

Study unravels novel cellular and molecular pathway that regulates innate, adaptive immunity

Researchers at Brigham and Women's Hospital have discovered a new cellular and molecular pathway that regulates CD4+ T cell response--a finding that may lead to new ways to treat diseases that result from alterations in these cells.

Novel technology platform for custom designing bacteriophages

Bacteriophages, known informally as phages, are viruses that can attack and kill specific bacteria. They occur everywhere in the natural world. Precisely because they are matched to just one specific type of bacteria, researchers and medics hope that phages can be engineered to combat certain bacterial infections.

Minor errors can lead to fatal consequences

It is not only about relatively minor gastrointestinal illnesses like self-limiting diarrhea. In particular among persons from risk groups (small children, expectant mothers, very old people or people whose immune system has been weakened by previous illness), a food-borne infection can also be severe, cause lasting damage and even prove fatal under certain circumstances.

Cannabis Quality and Contamination Testing

Dr. Bob Clifford has published and presented over 125 papers in the fields of food, pharmaceutical, environmental, energy, geology, material science, photonics, and cannabis. However, his true love is in food. After graduating with his Ph.D., he left his job with the FDA for Shimadzu where he has worked for the last 26 years.

Scientists study behavior of Listeria monocytogenes during asymptomatic infection

Listeriosis is a disease caused by eating foods that have been contaminated by the Listeria monocytogenes bacterium.

Researchers catch killer cells red-handed in the act of microbial murder

Immune cells called "killer cells" target bacteria invading the body's cells, but how do they do this so effectively? Bacteria can quickly evolve resistance against antibiotics, yet it seems they have not so readily been able to evade killer cells. This has caused researchers to become interested in finding out the exact mechanism that killer cells use to destroy bacterial invaders.

Using biologics during pregnancy may not raise infant's risk for opportunistic infections

Using a biologic therapy to manage rheumatoid arthritis may not significantly increase an infant's risk for developing opportunistic infections like pneumonia, meningitis, and tuberculosis, according to new research findings presented this week at the 2017 ACR/ARHP Annual Meeting in San Diego.

Study into killer T-cell activity could provide roadmap for tackling antibiotic resistance

In a study that could provide a roadmap for combatting the rising threat of drug-resistant pathogens, researchers have discovered the specific mechanism the body's T cells use to kill bacteria.

Bacteria release membrane-derived vesicles that may have different functions during infection

Bacteria release membrane-derived vesicles (MVs), which are small particles that can transport virulence factors to neighboring bacteria or to the cells of a mammalian host. This special MV-based system for delivering toxic proteins and nucleic acids in a protected manner to the target cells may have different specific functions depending on whether the bacterium acts as an extracellular or intracellular pathogen.

Scientists show how immune system can be modulated by manipulation of sugar metabolism

In its attempt to fight a serious bacterial infection, caused by listeria, for example, the immune system can become so over-activated that the resulting inflammatory response and its consequences can quickly lead to death.
