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.

UCI-led study point to new approach for treating foodborne illnesses

UC Irvine microbiologists have learned how a probiotic bacterium used to treat irritable bowel syndrome can soothe gut bacterial infections caused by Salmonella, paving the way for potential relief from foodborne illnesses that affect millions of people annually.

Chickens purchased from farmers markets carry higher bacterial loads

Raw, whole chickens purchased from farmers markets throughout Pennsylvania contained significantly higher levels of bacteria that can cause foodborne illness compared to those purchased from grocery stores in the region, according to a small-scale study by researchers in Penn State's College of Agricultural Sciences

Researchers identify new cellular source for disease-fighting protein

Researchers at UT Southwestern Medical Center report the identification of a new cellular source for an important disease-fighting protein used in the body's earliest response to infection.

Researchers discover role of TonB bacterial protein that causes various diseases

A Kansas State University-led study has discovered the role of a protein in bacteria that cause a wide variety of diseases, including typhoid fever, plague, meningitis and dysentery. The results may lead to new and improved antibiotics for humans and animals.

New approach may reduce time to identify Salmonella strains, say researchers

A new approach may be able to reduce by more than half the time it takes health officials to identify Salmonella strains, according to researchers in Penn State's College of Agricultural Sciences.

Circadian rhythms can boost body's ability to fight intestinal bacterial infections, say researchers

Circadian rhythms can boost the body's ability to fight intestinal bacterial infections, UC Irvine researchers have found.

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.

New approach to genetic engineering reduces time and effort needed to insert genes into bacteria

A new, streamlined approach to genetic engineering drastically reduces the time and effort needed to insert new genes into bacteria, the workhorses of biotechnology, scientists are reporting.

New study provides clear picture of the impact and causes of diarrheal diseases

A new international study published today in The Lancet provides the clearest picture yet of the impact and most common causes of diarrheal diseases, the second leading killer of young children globally, after pneumonia.

New research ties mushrooms to potential health outcomes

New research published as abstracts in The FASEB Journal and presented at Experimental Biology 2013 ties mushrooms to potential health outcomes - demonstrating that mushrooms provide more to a dish than just flavor.

Edible malarial vaccine may work against other viral and bacterial infections

Can scientists rid malaria from the Third World by simply feeding algae genetically engineered with a vaccine? That's the question biologists at UC San Diego sought to answer after they demonstrated last May that algae can be engineered to produce a vaccine that blocks malaria transmission.

Researchers use metagenomics to identify the cause of outbreaks of bacterial infection

Researchers have been able to reconstruct the genome sequence of an outbreak strain of Shiga-toxigenic Escherichia coli (STEC), which caused over 50 deaths in Germany, using an approach known as metagenomics which bypasses the need for growing bacteria in the lab.

Virginia Tech scientists provide new evidence that biofilms are at work in survival of Salmonella

Virginia Tech scientists have provided new evidence that biofilms - bacteria that adhere to surfaces and build protective coatings - are at work in the survival of the human pathogen Salmonella.

Researchers use metagenomics to reconstruct genome sequence of Shiga-toxigenic Escherichia coli

Researchers have been able to reconstruct the genome sequence of an outbreak strain of Shiga-toxigenic Escherichia coli using metagenomics (the direct sequencing of DNA extracted from microbiologically complex samples), according to a study in the April 10 issue of JAMA, a Genomics theme issue.

Research findings could lead to new targets for treating inflammatory disorders

Researchers at UC Davis have shown how the innate immune system distinguishes between dangerous pathogens and friendly microbes. Like burglars entering a house, hostile bacteria give themselves away by breaking into cells. However, sensing proteins instantly detect the invasion, triggering an alarm that mobilizes the innate immune response.

Oral supplement of live R. Opacus may help pigs stay healthy during weaning

A common type of bacteria may help pigs stay healthy during weaning. In a study of 36 weanling-age pigs, researchers found that a dose of lipid-producing Rhodococcus opacus bacteria increased circulating triglycerides. Triglycerides are a crucial source of energy for the immune system.
