Creating an environment that nurtures the trillions of beneficial microbes in our gut and, at the same time, protects us against invasion by food-borne pathogens is a challenge. A study published on August 8 in PLOS Pathogens reveals the role of a key player in this balancing act. SIGIRR is a protein present at the surface of the cells that line the gut that dampens the innate (non-specific) immune response of these cells to bacteria. The new study, led by Xiaoxia Li (from the Lerner...

Uncovering The History Of Medieval Leprosy With Genomics
2013-06-14 14:24:28

Lee Rannals for redOrbit.com — Your Universe Online Scientists are using thousand-year-old remains to help reconstruct the genomes of the medieval leprosy pathogen and uncover the history of the disease. Researchers wrote in Science magazine about how they used the remains of skeletons to successfully reconstruct a dozen medieval and modern genomes of the leprosy-causing bacteria Mycobacterium leprae. They were able to create a genome from archaeological finds for the first time...

A sugar polymer found on the cell surface of multiple pathogens could be key to developing a 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...

Our gut is home to trillions of bacteria, numbering more than the cells in the rest of our body, and these bacteria help us to digest our food, absorb nutrients and strengthen our immune system. This complex bacterial ecosystem, called the gut microbiota, also helps to prevent bad bacteria from colonizing our bodies and making us ill. As part of the symbiotic relationship between the gut microbiota and our bodies, the bacteria derive nutrition from our food and convert it into compounds...

How Does Salmonella Spread Through The Body?
2012-12-08 07:36:40

redOrbit Staff & Wire Reports - Your Universe Online A study from Cambridge University researchers shines new light on exactly how Salmonella spreads throughout a person's body -- work that could help medical experts overcome roadblocks in the development of vaccines and other forms of therapy to help combat the disease-causing bacteria. By analyzing salmonellae, which are typically found growing inside of immune system cells during an infection, the researchers discovered the...

Researchers track the spread of human invasive non-Typhoidal Salmonella in sub-Saharan Africa A new study out today (Sunday 30 September) reveals that the emergence and spread of a rapidly evolving invasive intestinal disease, that has a significant mortality rate (up to 45%) in infected people in sub-Saharan Africa, seems to have been potentiated by the HIV epidemic in Africa. The team found that invasive non-Typhoidal Salmonella (iNTS) disease is caused by a new form of the bacteria...

The novel Natural Sciences Bibliographic Web Portal aims to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences. The site has now included the two new sections Necrosis and Pathogen. While the publishers target to publish a total of over 21 million references until 2014, the site currently contains 750,000 posts, increasing by about 20,000 items every day. These references contain a minimum of bibliographic information including title,...

Rather than trying to kill bacteria outright with drugs, Université de Montréal researchers have discovered a way to disarm bacteria that may allow the body's own defense mechanisms to destroy them. "To understand this strategy one could imagine harmful bacteria being like Darth Vader, and the anti-virulence drug would take away his armor and lightsaber," explained Dr. Christian Baron, the study's lead author and Professor at the Department of Biochemistry. "A naked...

Acinetobacter baumanni, a pathogenic bacterium that is a poster child of deadly hospital acquired infections, is one tough customer. It resists most antibiotics, is seemingly immune to disinfectants, and can survive desiccation with ease. Indeed, the prevalence with which it infects soldiers wounded in Iraq earned it the nickname "Iraqibacter." In the United States, it is the bane of hospitals, opportunistically infecting patients through open wounds, catheters and breathing tubes. Some...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
