Salmonella News and Research

RSS

Salmonella is actually a group of bacteria that can cause diarrheal illness in humans. They are microscopic living creatures that pass from the feces of people or animals to other people or other animals. There are many different kinds of Salmonella bacteria. Salmonella serotype Typhimurium and Salmonella serotype Enteritidis are the most common in the United States. Salmonella germs have been known to cause illness for over 100 years. They were discovered by an American scientist named Salmon, for whom they are named.

Fiji ban on gatherings to curb typhoid outbreak

The health ministry of Fiji has issued a ban on public gatherings in the province of Bua due to an outbreak of typhoid. It has been reported that since January, 41 cases were recorded in Bua, in the northern island of Vanua Levu, with many concentrated in small villages. Fiji's main island of Viti Levu bore the brunt of a major Typhoid outbreak this time last year. At this stage, there have only been isolated cases.

Cockroaches are a leading trigger of allergies and asthma attacks

May marks National Allergy and Asthma Awareness Month, and the National Pest Management Association warns families that cockroaches are a leading trigger of allergies and asthma attacks. The pests' saliva, droppings and decomposing bodies contain allergen proteins known to trigger allergies and increase the severity of asthma symptoms, especially in children.

Salmonella enterica bacterium activates virulence genes through Fur protein

Salmonella enterica, one of the main causes of gastrointestinal infections, modulates its virulence gene expression, adapting it to each stage of the infection process, depending on the free iron concentration found in the intestinal epithelium of its host.

Food poisoning costs the United States billions: Report

According to a new report published Thursday, 14 different pathogens causing food poisoning cost the United States $14 billion annually in terms of human disease. The report comes from the University of Florida Emerging Pathogens Institute that found that out of all the pathogen-food combinations they studied, campylobacter in poultry was the single worst offender, causing more than 600,000 illnesses per year, hospitalizing more than 7,000 people and costing, annually, $1.3 billion and 9,500 quality-of-life years.

Researchers reveal how immune system distinguishes between beneficial and pathogenic organisms

The human gut is filled with 100 trillion symbiotic bacteria-ten times more microbial cells than our own cells-representing close to one thousand different species. "And yet, if you were to eat a piece of chicken with just a few Salmonella, your immune system would mount a potent inflammatory response," says Sarkis K. Mazmanian, assistant professor of biology at the California Institute of Technology (Caltech).

Scientists discover new mechanism behind Salmonella invasion into gut cells

Scientists from the Helmholtz Centre for Infection Research in Braunschweig, Germany have discovered a new, hitherto unknown mechanism of Salmonella invasion into gut cells: In this entry mode, the bacteria exploit the muscle power of cells to be pulled into the host cell cytoplasm.

Nanotechnology-based biosensor may allow early cancer, pathogen detection

A nanotechnology-based biosensor being developed by Kansas State University researchers may allow early detection of both cancer cells and pathogens, leading to increased food safety and reduced health risks.

Queen’s University completes first ever analysis of all food recalls over last decade

As the increasing number food scares causes consumers to question the safety of everyday food items, researchers at Queen's University Belfast have completed the first ever analysis of all the food recalls announced in the USA, UK and Ireland over the last decade.

Scientists show how E. coli strain causes infection in individuals

Scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, have shown how the O157:H7 strain of Escherichia coli causes infection and thrives by manipulating the host immune response.

Salmonella may serve as valuable tool to fight against cancer

University of Minnesota researchers are using salmonella - the bacteria commonly transmitted through food that sickens thousands of U.S. residents each year - to do what was once unthinkable: help people.

Scientist develops cryo-electron microscopy to clarify salmonellae structure

Bacteria like salmonellae infect their host cells by needle-shaped extensions which they create in large numbers during an attack. A group of Vienna-based scientists headed by Thomas Marlovits employed recently developed methods of cryo-electron microscopy and have been able to clarify the structure of this infection apparatus on the near-atomic scale.

Targets against MRSA in microgravity

NASA astronauts onboard Space Shuttle Discovery's final mission to the International Space Station (ISS) will carry out the eleventh scientific payload for Astrogenetix, a commercial biotech company based out of Austin, Texas. The research on STS-133 will focus on changes that occur to methicillin-resistant Staphylococcus aureus (MRSA) in microgravity, which can be targeted to create new vaccines and therapeutics.

Green on satellite images warns of hantavirus outbreaks

The risk of deadly hantavirus outbreaks in people can be predicted months ahead of time by using satellite images to monitor surges in vegetation that boost mouse populations, a University of Utah study says. The method also might forecast outbreaks of other rodent-borne illnesses worldwide.

First chromogenic culture medium to simultaneously detect Salmonella and Shigella

Hardy Diagnostics, an ISO certified biomedical firm, is pleased to announce the release of HardyCHROM™ SS, a highly selective chromogenic medium recommended for use as a primary screening medium for the isolation and differentiation of Salmonella and Shigella spp. from stool cultures. These two pathogens can be easily distinguished from non-pathogenic enteric bacteria based on colony color.

More people sick with salmonella from custard pastries

According to South Australia Health authorities, 13 more people have fallen ill with salmonella that spread via three types of custard-filled pastries made in Adelaide. This brings the total number of ill people to 74 with 29 admitted to hospital with salmonella typhimurium phage type 9 infection. The custard-filled products from Vili’s and St George Cakes and Gelati were recalled after being associated with the salmonella outbreak.
