Food Poisoning News and Research

RSS

Food poisoning is a term given to infections with bacteria, parasites, viruses, or toxins from germs that affects humans via contaminated food or water.

Scientists solve structure of infection tool used by Yersinia bacterium

Abdominal pain, fever, diarrhoea -- these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called injectisome.

Infrared light allows characterization of pathogens

The bacterium Staphylococcus aureus (S. aureus) is commonly found in nature and frequently colonizes the skin and the upper respiratory tract of humans. A healthy immune system can fight the microorganism but once the immune system is weakened the pathogen can spread and lead to life-threatening diseases of the lungs, the heart and other organs.

Treating bacteria with silver compounds boosts efficacy of old antibiotics

Slipping bacteria some silver could give old antibiotics new life, scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University reported June 19 in Science Translational Medicine.

Common sugar molecule promising target for development of broad-spectrum vaccine

Developing new vaccines to protect against diseases that plague humans is fraught with numerous challenges-one being that microbes tend to vary how they look on the surface to avoid being identified and destroyed by the immune system. However, researchers from Brigham and Women's Hospital (BWH) have discovered a sugar polymer that is common on the cell surface of several pathogens.

Molecular switch protects salmonella from harm during infection

For the first time, researchers have found a particular kind of molecular switch in the food poisoning bacteria Salmonella Typhimurium under infection-like conditions. This switch, using a process called S-thiolation, appears to be used by the bacteria to respond to changes in the environment during infection and might protect it from harm, researchers report this week online in the Proceedings of the National Academy of Sciences Early Edition.

Carob extract could fight the microbe responsible for listeriosis

The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series reports that an antibacterial extract from the leaves of the carob tree (the source of a popular chocolate substitute) could fight the microbe responsible for the serious form of food poisoning called listeriosis.

Researcher explores new PCR system to discover dangerous foodborne pathogens

Pina Fratamico is on the quest to find the easiest and fastest way to test for harmful Escherichia coli in ground beef. In an article published in Frontiers in Microbiology on the 20th of December, she explores using a next-generation real-time polymerase chain reaction (PCR) system to discover specific gene targets that indicate the presence of dangerous foodborne pathogens. The results show that assays performed using this PCR system are rapid, sensitive, and reliable.

Study suggests that existing HIV drug could be a potential therapy for Staph infections

A new study by NYU School of Medicine researchers suggests that an existing HIV drug called maraviroc could be a potential therapy for Staphylococcus aureus, a notorious and deadly pathogen linked to hundreds of thousands of hospitalizations each year.
