Ten years after the SARS outbreak, scientists have uncovered genome sequences of a new virus closely related to the SARS coronavirus that erupted in Asia in 2002 to 2003, which caused a global pandemic crisis.
Doctors may one day be able to control a patient's HIV infection in a new way: injecting swarms of germ-fighting antibodies, two new studies suggest. In monkeys, that strategy sharply reduced blood levels of a cousin of HIV.
Researchers have found a more accurate method to screen for bacterial meningococcal infection in its early stages, when it's hardest to detect.
Two subtypes of human papillomavirus (HPV) prevented by vaccines are half as likely to be found in African-American women as in white women with precancerous cervical lesions, according to researchers.
In a pair of landmark studies that exploit the genetic sequencing of the “missing link” cold virus, rhinovirus C, scientists have constructed a 3-D model of the pathogen that shows why there is no cure yet for the common cold.
The considerable diversity of HIV worldwide represents a critical challenge for designing an effective HIV vaccine. Now, a scientific team has shown that bioinformatically optimized HIV vaccine antigens might be useful in the design of a global HIV vaccine.
In the fight to cure human immunodeficiency virus (HIV), researchers have been dealt a blow. A new study shows that the pool of inactive HIV viruses that lingers silently in a patient’s body is larger than expected.
Doctors now have convincing evidence that they put HIV into remission, hopefully for good, in a Mississippi baby born with the AIDS virus— a medical first that is prompting a new look at how hard and fast such cases should be treated.
Veterinary researchers have helped identify the origin and possible evolution of an emerging swine virus with high mortality rates that has already spread to at least 17 states. They have traced the recent U.S. outbreaks to a strain from the Anhui province in China.
A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.
Scientists have discovered that the influenza virus is able to infect its host by first killing off the cells of the immune system that are actually best equipped to neutralize the virus.
Dormant viruses can lie within a human host until the proper conditions for their activity are provided. You might think of viruses' as robots that need to take over a factory to make more of themselves. Without that, the viruses are dormant.
In very rare cases, fungal infections can spread below the skin’s surface and onto the lymph nodes, bones, digestive tract or even the brain. Researchers have now discovered a genetic deficiency that allows the fungus to spread in this way, a condition called deep dermatophytosis.
Human breast milk is sold for babies on several online sites for a few dollars an ounce, but a new study says buyer beware: Testing showed it can contain potentially dangerous bacteria including salmonella.
Determining whether a bacterium is harmful typically requires growing cultures from samples of saliva or blood— a time-intensive laboratory procedure. Now, researchers have developed a microfluidic device that could speed the monitoring of bacterial infections associated with cystic fibrosis and other diseases.
In two parallel projects, researchers have created new genomes inside the bacterium E. coli in ways that test the limits of genetic reprogramming and open new possibilities for increasing flexibility, productivity and safety in biotechnology.
Semprus BioSciences, a startup co-founded by two MIT alumni, is developing a novel biomaterial for implanted medical devices that permanently barricades troublesome microbes from the device’s surface.
The federal Centers for Disease Control and Prevention say a rare amoeba, Naegleria fowleri, that caused the August death of a child in south Louisiana has been found in five locations in a north Louisiana water system.
A new study examined how cocaine affects a unique population of immune cells which are resistant to the virus that causes AIDS. The results: Cocaine makes the cells susceptible to infection with HIV, causing both significant infection and new production of the virus.
Hold your nose and don't spit out your coffee: Doctors have found a way to put healthy people's poop into pills that can cure serious gut infections - a less yucky way to do "fecal transplants." Canadian researchers tried this on 27 patients and cured them all after strong antibiotics failed to help.
Blood from HIV-infected human subjects shows an immune response against a cat AIDS virus protein, a surprise finding that could help scientists find a way to develop a human AIDS vaccine, researchers report. This discovery supports further exploration of a human AIDS vaccine derived from regions of the feline AIDS virus.
The notorious bacteria E. coli is best known for making people sick, but scientists have reprogrammed the microbe— which also comes in harmless varieties— to make it seek out and fight other disease-causing pathogens. This new type of E. coli that can even kill off slimy groups of bacteria called biofilms that are responsible for many hard-to-treat infections.
The report by scientists of a new hepatitis virus earlier this year was a false alarm, according to researchers who correctly identified the virus as a contaminant present in a type of glassware used in many research labs. Their finding highlights both the promise and peril of today’s powerful “next-generation” lab techniques.
Engineers have developed a new type of nanoparticle that protects a vaccine long enough to generate a strong immune response— not only in the lungs, but also in mucosal surfaces far from the vaccination site, such as the gastrointestinal and reproductive tracts.
Candida albicans is a double agent: In most of us, it lives peacefully, but for people whose immune systems are compromised by HIV or other severe illnesses, it is frequently deadly. Now, a new study shows how targeting a specific fungal component might turn the fungus from a lion back into a kitten.
