Though horizontal gene transfer (HGT) is widespread, genes and taxa experience biased rates of transferability. Curiously, independent transmission of homologous DNA to archaea, bacteria, eukaryotes, and viruses is extremely rare and often defies ecological and functional explanations. Here, we ... Read More
Ebola GP protein covers the virus' surface and is shed from infected cells during infection. Shed GP can trigger massive dysregulation of the immune response and affect the permeability of blood vessels.

A larger percentage of patients with human immunodeficiency virus (HIV) achieved normalization of CD4+ T-cell counts when they started antiretroviral therapy (ART) within 12 months of the estimated dates of seroconversion (EDS) rather than later, according to a report published online by JAMA In...

It's a dog eat dog world, and bacteria have been living in it for a long time. It's of no surprise that bacteria have a sophisticated arsenal to compete with each other for valuable resources in the environment. In 2010, work led by University of Washington Department of Microbiology Associate P... Read More
Take two poisonous mushrooms, and call me in the morning. While no doctor would ever write this prescription, toxic fungi may hold the secrets to tackling deadly diseases.
A team of Michigan State University scientists has discovered an enzyme that is the key to the lethal potency of poisonou... Read More
Diagnosing HIV and other infectious diseases presents unique challenges in remote locations that lack electric power, refrigeration, and appropriately trained health care staff. To address these issues, researchers funded by the National Institutes of Health (NIH) have developed a low-cost, elec... Read More
A common ingredient in vegetable oils may help reduce infection with a bacterium that can cause stomach cancer and peptic ulcers, according to a study by UC San Diego scientists.
The ingredient, linolenic acid, killed the bacterium Helicobacter pylori in mice and reduced inflammation without ... Read More
For many bacteria and parasites looking to get a load of the fresh nutritional bounty inside your body, the skin is the first and most important gatekeeper. Schistosomas, however, and burrow right on through. These waterborne blood flukes, responsible for 200 million total worldwide cases of Sch... Read More
For over a century, microbiologists have been using growth media solidified with agar to culture microbes from environmental samples. Individual cells are easily separated on the solid surface, allowing each cell to grow and divide and form a colony of thousands of clones. We can change the nutr... Read More
Why not eat locusts? Assuming you can find any fuel to cook em, and apart from deficiency illnesses, I've always wondered why people didn't hunker down and harvest them for emergency food. Did original peoples endure swarms by eating them? Did Euro food ... Read More
Natural genetic variation in a protective antiviral enzyme holds promise for new therapies.
Doctors have long been mystified as to why HIV-1 rapidly sickens some individuals, while in others the virus has difficulties gaining a foothold. Now, a study of genetic variation in HIV-1 and in the c... Read More
Viruses are masters at mutating.
So the big concern with deadly viruses, like Ebola and hepatitis C, is that they will evolve into more dangerous forms over time.
It looks like just the opposite is happening with HIV — although it's happening slowly.
"HIV can generate any mutation in th... Read More
Scientists reveal how penicillin deals bacteria a devastating blow – work that may lead to new antibiotics.
Penicillin, the wonder drug discovered in 1928, works in ways that are still mysterious almost a century later. One of the oldest and most widely used antibiotics, it attacks enzymes th... Read More

New coatings to apply to soft cheese have been developed by researchers. These coatings are totally edible and have an antimicrobial capacity, which increases the lifespan of the cheese. These films incorporate oregano and rosemary essential oils as antimicrobial agents, and chitosan, a by-produ... Read More
Everybody and his uncle, it seems, has an idea of something that might work to cure people infected with the deadly virus.
When it comes to treatments for Ebola, there has been a nearly four-decade-long drought. Nothing in the medical arsenal attacks the virus directly. For the most part, p... Read More
Researchers at Tufts University, in collaboration with a team at the University of Illinois at Champaign-Urbana, have demonstrated a resorbable electronic implant that eliminated bacterial infection in mice by delivering heat to infected tissue when triggered by a remote wireless signal. The si... Read More
Dec. 1 has been World AIDS Day since 1988 — but though the awareness and activism around the diseases has changed drastically during the years between then and now.
To see just how much our understanding and attitudes have evolved, take a look back at TIME’s coverage of AIDS through these sev... Read More
