95% of people don’t wash their hands correctly: Study

Handwashing is the most effective thing one can do to reduce the spread of infectious disease.

When consulting the CDC’s official guide to handwashing you might be surprised to learn that they don’t distinguish between using warm or cold water.They say what is important is that you use soap, that you scrub well (including the backs of your hands, between your fingers, and under your nails) for at least 20 seconds, and that you dry your hands afterwards. The CDC also officially recommends humming the “Happy Birthday” song twice through for an accurate measure of time.

Acne Drug Prevents HIV Breakout

Janice E. Clements, Ph.D.

Johns Hopkins scientists have found that a safe and inexpensive antibiotic in use since the 1970s for treating acne effectively targets infected immune cells in which HIV, the virus that causes AIDS, lies dormant and prevents them from reactivating and replicating.

Fungi Can Change Quickly, Pass Along Infectious Ability

100317144634

Studies done with this fungus have challenged existing beliefs about how quickly fungi can change their genetic makeup and become infectious.

Fungi have significant potential for “horizontal” gene transfer, a new study has shown, similar to the mechanisms that allow bacteria to evolve so quickly, become resistant to antibiotics and cause other serious problems.

Flightless Mosquitoes Developed to Help Control Dengue Fever

100222161958-large

Infected female Aedes aegypti mosquitoes transmit the virus causing dengue fever, but they are rendered flightless in a new strain genetically engineered by UCI and British scientists.

A new strain of mosquitoes in which females cannot fly may help curb the transmission of dengue fever, according to UC Irvine and British scientists.

Mouse With Human Liver: New Model for Treatment of Liver Disease

100222182144-large

Mice whose own liver cells have been replaced with human hepatocytes (shown in green) can be successfully infected with hepatitis B virus (shown in red) providing a new way to test novel therapies for debilitating human liver diseases.

How do you study-and try to cure in the laboratory-an infection that only humans can get? A team led by Salk Institute researchers does it by generating a mouse with an almost completely human liver. This “humanized” mouse is susceptible to human liver infections and responds to human drug treatments, providing a new way to test novel therapies for debilitating human liver diseases and other diseases with liver involvement such as malaria.

Bacteria (Streptococcus pneumoniae, red) under attack by a neutrophil (blue).

Scientists have long pondered the seeming contradiction that taking broad-spectrum antibiotics over a long period of time can lead to severe secondary bacterial infections. Now researchers from the University of Pennsylvania School of Medicine may have figured out why.

‘Broad Spectrum’ Antiviral Fights Multitude of Viruses

100201113801-large

Ebola virus. A small-molecule “broad spectrum” antiviral may be able to fight a host of viruses by attacking them through some feature common to an entire class of viruses.

The development of antibiotics gave physicians seemingly miraculous weapons against infectious disease. Effective cures for terrible afflictions like pneumonia, syphilis and tuberculosis were suddenly at hand. Moreover, many of the drugs that made them possible were versatile enough to knock out a wide range of deadly bacterial threats.

Artist’s rendering of viruses. Scientists have developed synthetic molecules capable of enhancing the body’s immune response to HIV and HIV-infected cells, as well as to prostate cancer cells.

Researchers at Yale University have developed synthetic molecules capable of enhancing the body’s immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases.
