Mtb produces specific protein that allows it to defuse and bypass body's security system

Tuberculosis, which kills over 2 million people each year, is caused primarily by infectious bacteria known as Mycobacterium tuberculosis - or Mtb. Mtb targets human immune cells as part of its strategy to avoid detection, effectively neutralizing the body's immune response.

Researchers retrace evolution of unusual bacterial infection

Researchers at Harvard Medical School and Children's Hospital Boston have retraced the evolution of an unusual bacterial infection as it spread among cystic fibrosis patients by sequencing scores of samples collected during the outbreak, since contained.

Mutations make Staph more resistant to antibiotics

Infectious diseases specialists from Austin Health are working closely with Microbiologists from the University of Melbourne to understand how Staph is becoming resistant to all antibiotic therapies.

Vaccination dramatically reduces incidence of Hib disease in young children

Vaccination against Haemophilus influenzae type b, or Hib, once the most common cause of bacterial meningitis in children, has dramatically reduced the incidence of Hib disease in young children over the past 20 years, according to a study published in Clinical Infectious Diseases and available online.

Xylitol can prevent inner ear infections in healthy children

There is "fair evidence" to support the use of xylitol, a natural sweetener used in gums and mints, to prevent inner ear infections in healthy children, a new evidence review finds.

Enzyme research may lead to drugs with fewer side effects

A tree outside Oak Ridge National Laboratory researcher Pratul Agarwal's office window provided the inspiration for a discovery that may ultimately lead to drugs with fewer side effects, less expensive biofuels and more.

FDA testing of imported seafood inadequate

Finfish, shrimp, and seafood products are some of the most widely traded foods and about 85 percent of seafood consumed in the U.S. is imported. A new study by researchers from the Johns Hopkins Center for a Livable Future at the Bloomberg School of Public Health shows that testing of imported seafood by the U.S. Food and Drug Administration (FDA) is inadequate for confirming its safety or identifying risks.

Study reveals role of circadian rhythms in regenerative capacity of skin stem cells

The investigation reveals the role of the daily biological clock (circadian rhythms) in the regenerative capacity of skin stem cells. Disruption of this rhythm results in premature tissue ageing and a greater predisposition to the development of skin tumours. The

Human body better at fighting gum disease when fat cells disappear

Case Western Reserve University School of Dental Medicine researchers found the human body is better at fighting gum disease when fat cells, which trigger inflammation, disappear.

Neogen's new Soleris test detects yeast and mold in 48 hours

Neogen Corporation has developed an even quicker method to rapidly and accurately detect yeast and mold in food products. Neogen's new Soleris® test detects yeast and mold in 48 hours or less — conventional methods take up to 5 days.

MRSA co-infection increases risk of flu-related mortality among children

During the 2009 H1N1 influenza pandemic, many previously healthy children became critically ill, developing severe pneumonia and respiratory failure, sometimes fatal. The largest nationwide investigation to date of influenza in critically ill children, led by Children's Hospital Boston, found one key risk factor: Simultaneous infection with methicillin-resistant Staphylococcus aureus (MRSA) increased the risk for flu-related mortality 8-fold among previously healthy children.

Children with polyarticular JIA benefit from early and aggressive therapy

Children with juvenile arthritis who are treated early and aggressively have better outcomes, according to research presented this week at the American College of Rheumatology Annual Scientific Meeting in Chicago.

Ansell launches GAMMEX Powder-Free glove with AMT Antimicrobial Technology in Europe

Global leader in healthcare protection and safety solutions lands CE Mark for GAMMEX Powder-Free Gloves with AMT Antimicrobial Technology.

Common gut pathogen increases activity of SMO gene and causes colon tumors

Working with lab cultures and mice, Johns Hopkins scientists have found that a strain of the common gut pathogen Bacteroides fragilis causes colon inflammation and increases activity of a gene called spermine oxidase (SMO) in the intestine.

'Medicine that grows' confronts antibiotics resistance

It's been called "the trots," "Montezuma's Revenge," "the runs" and worse. But no matter the name, when it strikes, victims wish for a medicine that could go straight to the offending bacteria to quickly knock it dead.

Whole genome sequencing can identify strains of caries-causing bacteria

Severe early childhood caries can destroy most of a child's teeth by age three, and disproportionately affects underserved populations, including American Indians and Alaskan natives. Although the link between Lactobacilli bacteria (Lb) and severe early childhood caries has been known for almost a century, progress in delineating which of 140 Lb species are responsible for the disease has remained elusive.

Reduced diversity of intestinal microbiota associated with increased risk of allergic disease

Oversensitivity diseases, or allergies, now affect 25 per cent of the population of Denmark. The figure has been on the increase in recent decades and now researchers at the Copenhagen Prospective Studies on Asthma in Childhood (COPSAC), University of Copenhagen, are at last able to partly explain the reasons.

UC Merced professor designs powerful chemical inhibitor against HIV

In a significant step toward reducing the threat of HIV, UC Merced Professor Patricia LiWang has designed what may be the most effective chemical inhibitor against infection of the virus.

Bacteria rapidly exchange genetic information related to human disease and antibiotic resistance

Much as people can exchange information instantaneously in the digital age, bacteria associated with humans and their livestock appear to freely and rapidly exchange genetic material related to human disease and antibiotic resistance through a mechanism called horizontal gene transfer (HGT).

Targeted antibiotic safe and effective for irritable bowel syndrome

Among the most commonly used treatments for irritable bowel syndrome - which affects as many as 20 percent of the United States population - a targeted antibiotic was shown to be the safest in a new study by Cedars-Sinai researchers, based on an analysis of 26 large-scale clinical trials.
