Mouth Bacteria Can Change Its Diet, Supercomputers Reveal

Bacteria inside your mouth drastically change how they act when you're diseased, according to research using supercomputers at the Texas Advanced Computing Center (TACC). Scientists say these surprising findings might lead to better ways to prevent or even reverse the gum disease periodontitis, ... Read More

Pictures Considered #19. The Basal End of Bacterial Flagella

The end of bacterial flagella that is near the cell is a marvel of mechanical miniaturization — a molecular wheel that turns, just like the axle of a car. The assembly consists of a stator, the part that holds it in place, and a rotor, the part that turns. The rotor is a beautifully complex str... Read More

Watch This Week in Virology Episode 300 Live from ASM HQ Aug 26 7 pm ET

This Week in Virology, the podcast about viruses, celebrates its 300th episode on Tuesday, August 26, 2014 with a live recording at the Washington, DC headquarters of the American Society for Microbiology. This special episode w... Read More

New vaccines against an old disease: brucellosis

Brucellosis is a worldwide extended infectious disease of livestock (sheep, goats, cattle, cows, pigs, …) and remains one of the most common zoonotic infections, with more tan 500,000 new human cases worldwide every year. Control and eradication of brucellosis requires the use of animal vaccines... Read More

Asian Tiger Mosquito Could Expand Painful Caribbean Virus into U.S.

Rapid expansion of this species, which is more aggressive than the species that is now spreading chikungunya into the Caribbean, is worrying scientists.

In the past few months, passengers at North American airports have been warned that travel to the Caribbean might result in an unwanted souv... Read More

Graphic Warnings: Ebola Posters Keep The Virus On People's Minds

The campaign is called "Kick Back Ebola." But the posters pack a punch.

Sierra Leone has reported over 700 suspected Ebola cases, more than any other country this year. To help stop the outbreak, health workers have put up Ebola awareness signs all over Sierra Leone's seaside capital of Freet... Read More

Scientists Choose Sides In Safety Debate Over Lab-Made Pathogens

A smoldering debate about whether or not researchers should ever deliberately create superflu strains and other risky germs in the interest of science has flared once again.

Proponents of the work say that in order to protect the public from the next naturally occurring pandemic, they have to... Read More

Preemies’ gut bacteria may depend more on gestational age than environment​

Scientists believe babies are born with digestive systems containing few or no bacteria. Their guts then quickly become colonized by microbes — good and bad — as they nurse or take bottles, receive medication and even as they are passed from one adoring relative to another.

However, in infant... Read More

The viruses that spread antibiotic resistance

Bacteriophages are viruses that infect bacteria, and in the great war between humans and pathogenic bacteria they can act as allies for both sides. Phages that destroy their host bacteria can be used as antimicrobial therapy, complementing or replacing antibiotics. On the other hand as phages ar... Read More

Highly Drug Resistant, Virulent, Strain of Pseudomonas Aeruginosa Arises in Ohio (press release)

A team of clinician researchers has discovered a highly virulent, multidrug resistant form of the pathogen, Pseudomonas aeruginosa, in patient samples in Ohio. Their investigation suggests that the particular genetic element involved, which is still rare in the United States, has been spreading ... Read More

Elusive viral 'machine' architecture finally rendered

Biologists have worked with the Lambda virus as a model system for more than 50 years but they've never had an overarching picture of the molecular machines that allow it to insert or remove DNA from the cells that it infects. Now they can, thanks to an advance that highlights the intriguingly i... Read More

Native bacteria block Wolbachia from being passed to mosquito progeny

Native bacteria living inside mosquitoes prevent the insects from passing Wolbachia bacteria -- which can make the mosquitoes resistant to the malaria parasite -- to their offspring, according to a team of researchers.

The team found that Asaia, a type of bacteria that occurs naturally in Ano... Read More

‘Wormy’ Pills Might Fend Off Autoimmune Diseases

Scientists have identified peptides from parasitic hookworms that can calm the body’s immune response and perhaps pave the way to treat autoimmune diseases.

Experts believe the peptide molecules could help explain why worm infections can effectively treat diseases such as multiple sclerosis, ... Read More

Should experimental drugs be used in the Ebola outbreak?

Risks and benefits of unproven treatments, as World Health Organization approves use in crisis.

Two Liberian doctors are set to become the first Africans to receive an experimental drug against the Ebola virus. The news comes as the World Health Organization concludes that it is ethical to us... Read More

Wild sheep show benefits of putting up with parasites

In the first evidence that natural selection favors an individual's infection tolerance, researchers from Princeton University and the University of Edinburgh have found that an animal's ability to endure an internal parasite strongly influences its reproductive success. Reported in the journal ... Read More

Like cling wrap, new biomaterial can coat tricky burn wounds and block out infection

Wrapping wound dressings around fingers and toes can be tricky, but for burn victims, guarding them against infection is critical. Today, scientists are reporting the development of novel, ultrathin coatings called nanosheets that can cling to the body’s most difficult-to-protect contours and ke... Read More

Editing HPV's Genes To Kill Cervical Cancer Cells

Researchers have hijacked a defense system normally used by bacteria to fend off viral infections and redirected it against the human papillomavirus (HPV), the virus that causes cervical, head and neck, and other cancers.

Using the genome editing tool known as CRISPR, the Duke University rese... Read More

The typhoid fever pathogen uses a cloaking mechanism to evade neutrophil neutralization

Typhoid fever is caused by systemic infection with Salmonella enterica Typhi. In contrast, infection with the closely related bacterium Salmonella enterica Thyphimurium is usually limited to the gut and causes less serious diarrheal disease. Research comparing the two pathogens reveals how S. Ty... Read More
