Listeriosis News and Research

RSS

Listeriosis, a serious infection caused by eating food contaminated with the bacterium Listeria monocytogenes, has recently been recognized as an important public health problem in the United States. The disease affects primarily persons of advanced age, pregnant women, newborns, and adults with weakened immune systems. However, persons without these risk factors can also rarely be affected. The risk may be reduced by following a few simple recommendations.

Disease-causing bacteria use molecular "barcode" to distinguish between beneficial and toxic molecules

Researchers at McMaster University have discovered a molecular "barcode" system used by disease-causing bacteria to distinguish between beneficial and toxic molecules.

Fresh risks in ready-to-eat produce: Study reveals how common pathogens lurk in our salads

This research paper delves into the risks of contamination in ready-to-eat fruits and vegetables by enteric pathogens like E. coli, Salmonella, and Listeria, which can lead to foodborne illnesses. It also explores the contamination sources and plant-pathogen interactions, emphasizing the importance of improved safety measures in the food supply chain.

New insights on the mechanisms of transmission of bacterial pathogen that causes listeriosis

Listeriosis is a zoonotic disease of food origin that can cause, both in the human species and in animals, symptoms of gastroenteritis, meningitis, bacteremia and miscarriages.

UTSW researchers show how vulnerable cells armor themselves against infection

Cells in some of the body's most vulnerable entry routes to bacterial infection buffer themselves when the immune system detects danger by reorganizing the cholesterol on their surfaces, a new study led by UTSW scientists suggests.

Salmonella causes nearly one in three foodborne outbreaks in the EU

Nearly one in three foodborne outbreaks in the EU in 2018 were caused by Salmonella. This is one of the main findings of the annual report on trends and sources of zoonoses published today by the European Food Safety Authority and the European Centre for Disease Prevention and Control.

Scientists sheds light on small protein and its role in immune response

The immune system is the body’s defense against disease-causing pathogens. It works by warding off disease and potentially-damaging foreign bodies. Now, a team of researchers have developed a new method to shed light on the basic defense mechanism of the immune system.

Researchers discover most virulent representatives of listeriosis pathogen

The bacterium Listeria monocytogenes can cause listeriosis, a life-threatening infection in animals and humans. Contaminated food is a frequent source of infection. Elderly people, people with a weakened immune system and pregnant women are particularly at risk with a mortality rate of up to 30 per cent.
