But it doesn’t only suck blood – the flea’s saliva keeps blood from clotting. And riding along in that saliva are bacteria.

In a world liter... Read More

SIU scientist says his vaccine could protect against herpes

A scientist at Springfield's Southern Illinois University School of Medicine says he has developed a vaccine that could provide near-total protection against genital herpes, one of the world's most common sexually transmitted infections.

"To me, this is the future genital herpes vaccine," Wil... Read More

DNA of Pest-Killing Wasps Could Unlock Other Secrets

The science community is abuzz over the news that the entire genetic makeup of a highly valuable wasp has been determined via DNA sequencing.

Nasonia is the name given to three different species of pinhead-sized, parasitic wasps that act as a kind of natural pesticide: They sting -- and lay t... Read More

Video: WHO's H1N1 hype: Experts not surprised

In this video from India's NDTV, reporters address growing public anger against the World Health Organisation (WHO) for reportedly making swine flu pandemic bigger than it really was. Health experts in India say this isn't the first time WHO has pushed for programmes, even though they are not ne... Read More

One in five Americans got swine flu vaccine, CDC reports

About one in five Americans has been vaccinated against swine flu, according to the government's first detailed estimates of vaccination rates against the pandemic.

The estimate is based on two government telephone surveys done in December and early January. The surveys concluded that an esti... Read More

Lung Infection Up in Wake of Kids' Pneumonia Vaccine

Since the PCV7 early childhood vaccine for bacterial pneumonia was introduced in the United States in 2000, the number of children hospitalized for pneumonia because of pneumococcus has decreased by 50 percent and bacterial pneumonias have decreased overall, new research shows.

But the scient... Read More

Phillips-University of Marburg Study Finds Microbes Help Mother Protect Kids from Allergies

The tendency to reach for disinfectants, stringent cleaners, and hand sanitizers is high this time of year for cold and flu prevention. During pregnancy women tend to be extra careful to reduce exposure to bugs of any kind. It appears, however, that a little exposure can go a long way as a new... Read More

Sulphur-eating bacteria limit acid run-off and CO2

Using two beamlines at the Canadian Light Source (CLS) and a third at the Advanced Light Source (ALS), researchers from McMaster University have found that two species of bacteria isolated from a mine tailings pond in northern Ontario actually work together to limit the amount of acid produced b...

Latinos and blacks in California more likely to die of H1N1 than whites

California Latinos have been nearly twice as likely as whites to die of H1N1 flu since the pandemic began last spring, according to statewide figures released this morning by the California Department of Public Health.

Over the same months, blacks in the state have been 50% more likely to die... Read More

Drug-resistant HIV set to surge

HIV is striking back against the antiretroviral drugs that keep it largely in check in rich countries, thanks both to its exposure to the major drugs and to individuals who don't realise they're infected and so spread resistant strains to new partners.

Drug-resistant strains of HIV have alrea... Read More

Scientists hope to end sleeping sickness by making parasite that causes it to self-destruct

New data offer an up-close look at the enzyme that protects the protozoa and how one compound obstructs those efforts.

After many years of study, a team of researchers is releasing data today that it hopes will lead to new drug therapies that will kill the family of parasites that causes ... Read More

The effects of circumcision on the penis microbiome.

Circumcision is associated with significant reductions in HIV, HSV-2 and HPV infections among men and significant reductions in bacterial vaginosis among their female partners.

METHODOLOGY/PRINCIPAL FINDINGS: We assessed the penile (coronal sulci) microbiota in 12 HIV-negative Ugandan men bef... Read More

Making microscopic worms into a more deadly insecticide

Microscopic nematode worms can be a potent organic insecticide, killing crop-raiding bugs without harming plants or beneficial insects and without environmental side effects of chemical. The problem is that when the worms are mass-bred for agricultural purposes, they tend to, as Byron Adams says... Read More

Rising obesity prompts higher antibiotic doses call

The standard "one-size fits all" dose may not clear infection in larger adults and increases the risk that resistance will develop, they argue.

More work is needed to guide GPs on how and when to alter doses, an editorial in The Lancet to accompany the study by doctors from Greece and the US ... Read More

Paradigm-Changing Mechanism is Revealed for the Control of Gene Expression in Bacteria

A new study led by researchers at NYU Langone Medical Center is shedding new light on the action of Rho, a key regulatory protein in E. coli and many other bacteria. The study, published in the Jan. 14, 2010 issue of Nature, reveals a new paradigm to understand the molecular principles of gene t... Read More

WHO official denies exaggeration about dangers of swine flu pandemic

A top World Health Organization official dismissed charges Thursday that the agency exaggerated the threat posed by the H1N1 virus and that it had been unduly influenced by the pharmaceutical industry to issue dire warnings about the swine flu pandemic.

Sequencing Wasp Genome Sheds New Light on Sexual Parasite

About 100 million years ago, the bacterium Wolbachia came up with a trick that has made it one of the most successful parasites in the animal kingdom: It evolved the ability to manipulate the sex lives of its hosts.

"When it developed this capability, Wolbachia spread rapidly among the world'... Read More
