Salk scientists re-engineered the bacterial defense system CRISPR to recognize HIV inside human cells and destroy the virus, offering a potential new therapy.
In the ongoing Ebola outbreak in West Africa, whose death toll is approaching 10,000, little information has been available about how the human immune response unfolds after infection. Researchers have now obtained a first look at the immune responses in four Ebola virus disease survivors who received care at Emory University Hospital in 2014, by closely examining their T cells and B cells during the acute phase of the disease.
Marking the progress in controlling its Ebola outbreak, the Liberian government dismantled a crematorium and removed drums containing the ashes of more than 3,000 Ebola victims cremated during the height of the epidemic, whose last patient was discharged last week.
Three startups are taking advantage of new technology to help patients get treatment for various diseases all over the world.
The United Nations is urging donors, organizations and countries fighting Ebola in West Africa not to give in to complacency as the death toll from the virus climbs toward 10,000.
Mouse studies may lead to development of human therapies.
Future treatments could bind to vulnerable site in viruses causing a variety of diseases.
Sierra Leone's vice president has put himself in quarantine following the death from Ebola of one of his security guards.
Researchers have identified a previously unknown process that many bacteria, including those that cause disease in humans, use to survive. Their discovery could lead to new therapies for bacterial infections like MRSA and tuberculosis that are resistant to current antibiotic treatments.
Contaminated medical instruments are suspected in a "superbug" outbreak at a Los Angeles hospital that has infected at least seven patients, two of whom died. More than 170 others may have been exposed to the antibiotic-resistant bacteria.
New research suggests that this bacterium causes more often causes severe sore throats in young adults than streptococcus — the cause of the much better known strep throat.
Global health organizations said Tuesday that AIDS is now the leading cause of death for adolescents in Africa, and the second leading cause of death among adolescents globally.
The Ebola virus remains viable for at least seven days after death in non-human primates. A new study, published in Emerging Infectious Diseases, suggests that Ebola transmission from deceased individuals may be possible for an extended period of time after death, underscoring the importance of using safe practices for handling corpses.
This winter's nasty flu season has peaked and is clearly retreating, a new government report shows.
Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus.
Microbes, small and ancient life forms, play a key role in maintaining life on Earth. As has often been pointed out, without microbes, we’d die—without us, most microbes would get along just fine.
For decades, scientists have thought the bacteria that cause the bubonic plague hijack host cells at the site of a fleabite and are then taken to the lymph nodes, where the bacteria multiply and trigger severe disease. But UNC School of Medicine researchers discovered that this accepted theory is off base. The bacteria do not use host cells; they traffic to lymph nodes on their own and not in great numbers.
Ebola has claimed nearly 9,000 lives in West Africa over the past year, although new infections have dropped dramatically in recent months.
Researchers have revealed new insights into possible ways to vaccinate people to generate potent antibodies of the type that are predicted to offer protection against diverse strains of the highly mutable HIV.
Several state legislatures are debating vaccine-related measures as dozens of people have fallen ill from a measles outbreak that started at Disneyland in December and spread beyond the theme park.
In 2008, the World Health Organization announced a global effort to eradicate malaria, which kills about 800,000 people every year. As part of that goal, scientists are trying to develop new drugs that target the malaria parasite during the stage when it infects the human liver, which is crucial because some strains of malaria can lie dormant in the liver for several years before flaring up.
Since December, more than 100 people in 14 states have been infected with measles in an outbreak traced to Disneyland, Melissa Stockwell, MD, MPH, assistant professor of pediatrics and of population & family health, has spoken out to debunk seven myths about the measles vaccine.
The largest U.S. measles outbreak in recent history isn't the one that started in December at Disneyland. It happened months earlier in Ohio's Amish country, where 383 people fell ill after unvaccinated Amish missionaries traveled to the Philippines and returned with the virus.
The drop-off in Ebola infections is good news for Liberia, but it means there are not enough sick people to take part in the study.
Federal health officials faced tough questions from lawmakers Tuesday about why they didn't take steps to produce a better flu vaccine as it became clear that this year's version wasn't going to offer much protection.
