Post-disinfection clips retain aerobic and anaerobic bacteria, says study

Researchers at Tufts University School of Dental Medicine and the Forsyth Institute published a study today that found that a significant proportion of dental bib clips harbored bacteria from the patient, dental clinician and the environment even after the clips had undergone standard disinfection procedures in a hygiene clinic.

Researchers focus on understanding mechanistic, physiological aspects of conflicts in living cells

Bacteria appear to speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Certain genes are in prime collision paths for the moving molecular machineries that read the DNA code, as University of Washington scientists explain in this week's edition of Nature.

Viral protein hijacks cellular machinery and grabs the wheel

Northwestern Medicine scientists have identified a component of the herpesvirus that "hijacks" machinery inside human cells, allowing the virus to rapidly and successfully invade the nervous system upon initial exposure.

Microbiologists identify unique resistance mechanisms of E. coli to carbapenems

As public health authorities across the globe grapple with the growing problem of antibiotic resistance, Tufts University School of Medicine microbiologists and colleagues have identified the unique resistance mechanisms of a clinical isolate of E. coli resistant to carbapenems.

Presence of certain bacteria in stomach microbiota can prevent pathology from H. pylori

Mice with different naturally occurring stomach bacteria have distinct susceptibilities to disease caused by Helicobacter pylori, the well-known cause of ulcers in humans, according to a study published online ahead of print in the journal Infection and Immunity.

New vaccine proves highly effective against H5N1 virus

Until now most experimental vaccines against the highly lethal H5N1 avian influenza virus have lacked effectiveness. But a new vaccine has proven highly effective against the virus when tested in both mice and ferrets. It is also effective against the H9 subtype of avian influenza.

A new strategy to prevent herpes virus infections

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a novel strategy for preventing infections due to the highly common herpes simplex viruses, the microbes responsible for causing genital herpes (herpes simplex virus 2) and cold sores (herpes simplex virus 1).

Anti-inflammatory drug naproxen may exhibit antiviral activity against influenza A virus

The over-the-counter anti-inflammatory drug naproxen may also exhibit antiviral activity against influenza A virus, according to a team of French scientists. The finding, the result of a structure-based investigation, is published online ahead of print in the journal Antimicrobial Agents and Chemotherapy.

Certain strains of lactobacillus bacteria can dampen production of toxic shock syndrome toxin 1

Certain Streptococci increase their production of toxic shock syndrome toxin 1, sometimes to potentially dangerous levels, when aerobic bacteria are present in the vagina. But scientists from the University of Western Ontario have discovered certain strains of lactobacillus bacteria are capable of dampening production of that toxin according to research published in the journal Applied and Environmental Microbiology.

New hope for treating, preventing malaria

Scientists at Oregon Health & Science University and the Portland VA Medical Center have developed a drug that may represent one of the world's best hopes for treating and preventing malaria - a disease that kills more than one million people each year.

Study: Novel strategy could lead to universal influenza vaccine that can provide long-lasting protection

Seasonal epidemics of influenza result in nearly 36,000 deaths annually in the United States, according to the Centers for Disease Control. Current vaccines against the influenza virus elicit an antibody response specific for proteins on the outside of the virus, specifically the hemagglutinin protein.
