Researchers discover how Salmonella thrives in the digestive tract

UC Irvine researchers have discovered how Salmonella, a bacterium found in contaminated raw foods that causes major gastrointestinal distress in humans, thrives in the digestive tract despite the immune system's best efforts to destroy it.

Azithromycin associated with lower duration of bacterial carriage in E. coli outbreak

In the E coli outbreak in Germany in May 2011, treatment with azithromycin was associated with a lower frequency of long-term carriage of the bacteria and shorter duration of shedding of the bacteria in stool specimens, according to a study in the March 14 issue of JAMA.

New work describes communities of active bacteria harbored by honey bee colonies

A novel study of honey bee genetic diversity co-authored by an Indiana University biologist has for the first time found that greater diversity in worker bees leads to colonies with fewer pathogens and more abundant helpful bacteria like probiotic species.

JAK-STAT inhibitors reverse MS-like disease in mice

A new class of drugs completing clinical trials soon for rheumatoid arthritis should be examined as a treatment for multiple sclerosis, according to the authors of a University of Alabama at Birmingham study published today in the Proceedings of the National Academy of Sciences.

Simple device for disinfecting stethoscopes

According to the Centers for Disease Control and Prevention (CDC) 1,900,000 people contract infections in hospitals, (Hospital Acquired Infections - HAIs) every year and well over 99,000 die as a result; more deaths than from AIDS, breast cancer and auto accidents combined.

New insight into causes of childhood pneumonia

The scientific journal Clinical Infectious Diseases has released its March Special Supplement focusing entirely on the research design of and pilot data from the Pneumonia Etiology Research for Child Health (PERCH) Project, which seeks to identify the causes of pneumonia among the world's most vulnerable populations.

Hospitals with infection control certification may have lower MRSA BSI rates

Hospitals whose infection prevention and control programs are led by a director who is board certified in infection prevention and control have significantly lower rates of methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSI) than those that are not led by a certified professional, according to a new study published in the March issue of the American Journal of Infection Control, the official publication of APIC - the Association for Professionals in Infection Control and Epidemiology.

Epidemic bacteria can damage mucins to enter and infect a body part

Boston, MA- Scientists from the Schepens Eye Research Institute, a subsidiary of Mass. Eye and Ear and affiliate of Harvard Medical School, have found for the first time that a bacterial pathogen can literally mow down protective molecules, known as mucins, on mucus membranes to enter and infect a part of the body.

Pink slime to make its way into school lunches: Debate ensues

McDonald's and other fast food chains may have removed “pink slime” from their foods but the ‘gooey’ sounding chemical treatment that removes bacteria from meat is still making its appearance at kids’ school lunches.

Reducing consumption of antimicrobial agents reduces resistance: DANMAP

Antimicrobial agents are the most important weapons in the fight against bacterial infections in humans and animals, but these agents can lose their potency. When bacteria are exposed to antimicrobial agents they can develop resistance. This would make it more difficult to treat common diseases such as pneumonia and other infections.

Queen's receives NICH&S grant to create vaccine against Pseudomonas

Queen's University Belfast scientists working on a vaccine to combat Pseudomonas have received a financial boost from Northern Ireland Chest Heart and Stroke.

Abbott, GenLab collaborate to develop new assay for PLEX-ID automated microbial identification system

Abbott announced today it will collaborate with Genetics Laboratory, Inc. on the development of a molecular diagnostic test that will be designed to rapidly detect microorganisms that cause orthopedic infections.

Special computer algorithms can help doctors to make rapid diagnoses of known diseases

Just like urine and blood, breath contains traces of the products of metabolism. Such products can also be signs of infection, inflammation or cancer. For their analysis, computational bioinformatics researchers at the Cluster of Excellence "Multimodal Computing and Interaction" at Saarland University developed special computer algorithms that can help doctors to make diagnoses quickly and reliably.

Bovine collagen can enhance gum healing

Receding gums often result in tooth sensitivity and can lead to decay of the root and persistent inflammation of the gum. New research published in BioMed Central's open access journal Head & Face Medicine demonstrates that a novel method using bovine collagen is able to enhance gum healing. This resulted in thicker margins around the tooth and, in over half the cases, complete coverage of exposed roots.

X-rays help decipher how natural antibiotics defy a longstanding set of chemical rules

Researchers working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules - a mechanism that has baffled organic chemists for decades.

Polymer-based medical implants can produce harmful free radicals

A polymer is a mesh of chains, which slowly break over time due to the pressure from ordinary wear and tear. When a polymer is squeezed, the pressure breaks chemical bonds and produces free radicals: ions with unpaired electrons, full of untapped energy. These molecules are responsible for aging, DNA damage and cancer in the human body.

Bacteria may be talking to each other with a contact-dependent language

What if bacteria could talk to each other? What if they had a sense of touch? A new study by researchers at UC Santa Barbara suggests both, and theorizes that such cells may, in fact, need to communicate in order to perform certain functions. The findings appear today in the journal Genes & Development.

Scientists determine chemical features of DHPS enzyme's active site

More than 70 years after the first sulfa drugs helped to revolutionize medical care and save millions of lives, St. Jude Children's Research Hospital scientists have determined at an atomic level the mechanism these medications use to kill bacteria. The discovery provides the basis for a new generation of antibiotics that would likely be harder for bacteria to resist and cause fewer side effects.

Researchers confirm how food poisoning bacteria hijack cell's sense of direction

Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells.

New prebiotic formula helps colonize newborn's gut with beneficial bacteria

Adding prebiotic ingredients to infant formula helps colonize the newborn's gut with a stable population of beneficial bacteria, and probiotics enhance immunity in formula-fed infants, two University of Illinois studies report.
