Probability of contamination during handshaking could be lower than is commonly perceived

Graduations are a celebration of achievement and growth, but could all the pomp and circumstance increase your risk of exposure to harmful bacteria? A team of researchers from the Johns Hopkins Bloomberg School of Public Health examined the risk of acquiring pathogenic bacteria such as Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) through shaking hands at graduation ceremonies across Maryland.

Super-resolution microscopy technique reveals how and why cell's defenses fail against plague

Researchers at Sandia National Laboratories have developed a super-resolution microscopy technique that is answering long-held questions about exactly how and why a cell's defenses fail against some invaders, such as plague, while successfully fending off others like E.coli.

FDA warns consumers about look like antimicrobial dietary supplements

The FDA is warning consumers not to use products marketed as dietary supplements that also claim to be antimicrobial (antibiotic, antifungal or antiviral) drugs. These illegal products are falsely promoted with claims to treat illnesses such as upper respiratory infections, sinusitis, pneumonia, bronchitis and the common cold.

MRSA superbug detected in bed bugs and supermarket meats: Report

Scientists have made an alarming discovery. They have found that bedbugs can carry the staph “superbug” MRSA (Methicillin-Resistant Staphylococcus aureus).

Fiji ban on gatherings to curb typhoid outbreak

The health ministry of Fiji has issued a ban on public gatherings in the province of Bua due to an outbreak of typhoid. It has been reported that since January, 41 cases were recorded in Bua, in the northern island of Vanua Levu, with many concentrated in small villages. Fiji's main island of Viti Levu bore the brunt of a major Typhoid outbreak this time last year. At this stage, there have only been isolated cases.

Cockroaches are a leading trigger of allergies and asthma attacks

May marks National Allergy and Asthma Awareness Month, and the National Pest Management Association warns families that cockroaches are a leading trigger of allergies and asthma attacks. The pests' saliva, droppings and decomposing bodies contain allergen proteins known to trigger allergies and increase the severity of asthma symptoms, especially in children.

PCR testing for B. burgdorferi bacteria in joint fluid may confirm Lyme arthritis diagnosis

New research shows that polymerase chain reaction testing for Borrelia burgdorferi DNA—the spirochetal bacteria transmitted by deer ticks—in joint fluid may confirm the diagnosis of Lyme arthritis, but is not a reliable indicator for active joint infection in patients whose arthritis persists after antibiotic therapy. Findings of this study are published in Arthritis & Rheumatism, a journal of the American College of Rheumatology.

Shared wind instruments may cause sickness

Germs survive for several days in wind instruments including the clarinet, flute, and saxophone, according to a pilot study published in the International Journal of Environmental Health Research. The researchers, led by Stuart Levy, MD, of Tufts University School of Medicine, urge proper cleaning of these instruments.

Gene manipulation can improve survival rates during sepsis infection

Sepsis is a major killer in hospital intensive care units. Researchers at Case Western Reserve University School of Medicine have found that manipulating a genetic factor that can launch or throttle the body's defenses can improve survival rates during bacterial infection.

Mosquito's midgut bacteria can inhibit malaria parasite development

Researchers at the Johns Hopkins Bloomberg School of Public Health have identified a bacterium in field-caught mosquitoes that, when present, stops the development of Plasmodium falciparum, the parasite that causes malaria in humans.

Sugar boosts effectiveness of first-line antibiotics against chronic bacterial infections

James Collins, a pioneering researcher in the new field of systems biology and a MacArthur Genius, says: "You know the old saying: 'a spoonful of sugar makes the medicine go down?' This is more like 'a spoonful of sugar makes the medicine work.'
