Gonorrhea Infections Start From Exposure To Seminal Fluid

Researchers have come a step closer to understanding how gonorrhea infections are transmitted. When Neisseria gonorrhoeae, the bacteria responsible for gonorrhea, are exposed to seminal plasma, the liquid part of semen containing secretions from the male genital tract, they can more easily move ...

Researchers map gene differences in yellow fever, malaria mosquitoes, to help prevent disease

Virginia Tech entomologists have developed a chromosome map for about half of the genome of the mosquito Aedes agypti, the major carrier of dengue fever and yellow fever.

With the map, researchers can compare the chromosome organization and evolution between this mosquito and the major carri... Read More

Hebrew U. researchers reach breakthrough on understanding how persistent bacteria are able to avoid antibiotics

In addition to the known phenomenon by which some bacteria achieve resistance to antibiotics through mutation, there are other types of bacteria, known as “persistent bacteria”, which are not resistant to the antibiotics but simply continue to exist in a dormant or inactive state while exposed t...

Battling Infection With Microbes

The human relationship with microbial life is complicated. At almost any supermarket, you can pick up both antibacterial soap and probiotic yogurt during the same shopping trip. Although there are types of bacteria that can make us sick, Caltech professor of biology and biological engineering Sa... Read More

Dueling Infections: Parasitic Worms Limit the Effects of Giardia, and Vice Versa

If the idea of hookworms makes you shudder, consider this: Those pesky intestinal parasites may actually help your body ward off other infections, and perhaps even prevent autoimmune and other diseases.

Studying members of the Tsimane, an indigenous population in the lowlands of Central Boliv... Read More

Study: Salad Ingredient Kills Drug-Resistant TB

One of the world's oldest known disinfectants – and favorite salad dressings – may prove even stronger than previously thought.

An international research team has found that vinegar – or, more specifically, the active ingredient in vinegar – can kill mycobacteria, including a highly drug-resi... Read More

A Bacterial Bioluminescent Valentine's Day

In this short post, I celebrate Valentine's Day with words of light---using bioluminescent bacteria! Read More

2,300 tubes containing SARS virus samples missing in France

A major French biomedical research body, the Pasteur Institute, have launched an investigation into the disappearance of some 2,300 test tubes containing samples of the SARS virus. The loss was discovered during an inventory.

The Pasteur Institute filed a so-called 'complaint against X' on Mo... Read More

Proof of life: Reevaluating oldest known Archean trace fossil for indications of early biology

In the hunt for early life, geobiologists seek evidence of ancient microbes in the form of trace fossils – geological records of biological activity – embedded in lavas beneath the ocean floor. Filamentous titanite (a calcium titanium silicate mineral) microtextures found in 3.45 billion-year-ol... Read More

New research shows that bacteria survive longer in contact lens cleaning solution than previously thought

Each year in the UK, bacterial infections cause around 6,000 cases of a severe eye condition known as microbial keratitis - an inflammation and ulceration of the cornea that can lead to loss of vision. The use of contact lenses has been identified as a particular risk factor for microbial kerati... Read More

How bacteria in your gut affect your mental health

Scientists searching for the underlying causes of mental illness have discovered a surprising contributor — it appears the bacteria that live in your gut may play a major role in your mental health and well-being.

CBC Radio science columnist Torah Kachur spoke to researchers such as Karen Mad... Read More

Environment influences ability of bacterium to block malaria transmission

The environment significantly influences whether or not a certain bacterium will block mosquitoes from transmitting malaria, according to researchers at Penn State.

The researchers used a species of malaria parasite that affects rodents, Plasmodium yoelii, and the mosquito, Anopheles stephens... Read More

MWV Episode 86 - The Microbiology of Cheese

Have you ever wondered why mozzarella bubbling and stretching between pizza slices is so different from the earthy flavors of blue-veined gorgonzola? The diversity of cheeses we love are created by encouraging and manipulating the growth of specific microbes. The American Socie... Read More

Tamoxifen drug appears to kill fungus associated with deadly brain infection

The drug tamoxifen appears to kill a fungus associated with a deadly brain infection that afflicts HIV/AIDS patients, according to a University of Rochester study published online today by mBio, the journal of the American Society for Microbiology.

How the Body’s Cells Hold on Tight

When I was nine, biology gave me my first existential crisis. If I am built out of trillions of tiny cells, I worried, what’s to keep me from crumbling into a pile like a dried-out sandcastle? Almost two decades later, as a Ph.D. student in mathematics at the University of California, Davis, I’m... Read More

Cancer-Causing HPV Virus Directly Damages DNA

Human papillomavirus (HPV) can damage chromosomes and genes directly, researchers report in a new study. HPV is a virus that can cause anal, cervical, head and neck cancers, and according to experts, it produces two viral proteins (E6 and E7) that are involved in the development of those diseas...

A WORD on the constraints of influenza virus evolution

Evolution proceeds by selection of mutants that arise by error-prone duplication of nucleic acid genomes. It is believed that mutations that are selected in a gene are dependent on those that have preceded them, an effect known as epistasis. Analysis of a sequence of changes in the influenza vir...
