Skin Microbiome Shaped By Human Immune System
2013-10-29 13:50:14

Cold Spring Harbor Laboratory Our skin plays host to millions of beneficial and potentially disease-causing microorganisms; however, whether our immune system influences these microbial communities to prevent disease is unknown. In a study published online in Genome Research, researchers have explored the microbes living on the skin of patients with primary immunodeficiencies with eczema-like skin conditions. The human body contains many microbes, some of which are necessary for healthy...

West African Bats Are Hosts To Multitude Of Different Haemosporidian Parasites
2013-10-21 13:55:21

Max Planck Institute In Europe, bats are normally discussed in the context of endangered species threatened by loss of their habitats. However, in recent years, bats have caught the eye of infection biologists. The animals are namely hosts to a surprising number of pathogens, many of which could be dangerous to humans. Scientists at the Max Planck Institute for Infection Biology, the Museum für Naturkunde in Berlin and the American Museum of Natural History have been able to identify in...

Device Developed That Speeds Concentration Step In Food-pathogen Detection
2013-10-15 12:18:00

Purdue University Researchers have developed a system that concentrates foodborne salmonella and other pathogens faster than conventional methods by using hollow thread-like fibers that filter out the cells, representing a potential new tool for speedier detection. The machine, called a continuous cell concentration device, could make it possible to routinely analyze food or water samples to screen for pathogens within a single work shift at food processing plants. "This approach...

Soaring Variety Of Malaria Parasites Found In Bats
2013-10-07 16:10:08

American Museum of Natural History Researchers have discovered a surprising diversity of malaria parasites in West African bats as well as new evidence of evolutionary jumps to rodent hosts. Led by scientists at the American Museum of Natural History, the Max Planck Institute for Infection Biology, and the Museum für Naturkunde, Berlin, the new study reveals that two bat-infecting parasites are closely related to parasites in rodents that are commonly used to model human malaria in...

Genomic Test Accurately Distinguishes Between Viral And Bacterial Infections
2013-09-19 09:19:39

Duke University Medical Center A blood test developed by researchers at Duke Medicine showed more than 90-percent accuracy in distinguishing between viral and bacterial infections when tested in people with respiratory illnesses. The test, which detects a specific genetic "signature" that the sick person's immune system expresses as a response to the virus, demonstrates a potential new method for diagnosing the source of illnesses that have long been tough to pinpoint. Reported in...

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...

Rapid, inexpensive test is promising for use in the field and in the lab, study results are published in PLOS ONE MOUNTAIN VIEW, Calif., May 20, 2013 /PRNewswire-iReach/ -- Specific Technologies, today announced the publication of results of the first study demonstrating detection of pathogenic bacteria, including potential bioterrorism agents such as Yersinia pestis and Bacillus anthracis which feature on the Center for Disease Control and Prevention's list of potential bio-threats....

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...
