U.S. health officials are monitoring the Ebola outbreak in Africa but say the risk of the deadly germ spreading to the United States is remote. The Centers for Disease Control on Monday sent a health alert to U.S. doctors about the outbreak.

One strategy for developing a highly effective HIV vaccine is to learn how some HIV-infected people naturally develop antibodies that can stop a high percentage of global HIV strains from infecting human cells in the laboratory. These so-called broadly neutralizing antibodies (bNAbs) develop too late to help infected people overcome the virus.
A nine-day quarantine imposed on parts of a northern Chinese city where a man there died of bubonic plague has been lifted, China's official news agency reported Thursday.
Health officials say that the head of the government lab which potentially exposed workers to live anthrax has resigned. Michael Farrell was head of the Centers for Disease Control and Prevention lab since 2009.
Parts of a northern Chinese city have been quarantined after state media said a man there died of bubonic plague. The Chinese news agency Xinhua said Tuesday that 151 people were under observation in the city of Yumen in Gansu province after authorities determined they had come in contact with a man who had died of the plague July 16.
The seriousness of disease often results from the strength of immune response, rather than with the virus, itself. Turning down that response, rather than attacking the virus, might be a better way to reduce that severity. Researchers have taken the first step in doing that for the H7N9 influenza, and their work has led to identification of six potential therapeutics for this highly virulent strain.
Many bacteria swim using flagella, corkscrew-like appendages that push or pull bacterial cells like propellers. It had been assumed that the flagella do all the work during swimming, while the rest of the cell body is just along for the ride. But new research shows that in at least one species, the cell body is actively carving out a helical trajectory through the water that produces thrust and contributes to the organism's ability to swim.
The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.
A research team has demonstrated that the viral reservoir of HIV-1 infection is established strikingly early after intrarectal simian immunodeficiency virus (SIV) infection of rhesus monkeys and before detectable viremia.
A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.” The advance could potentially lead to powerful new ways of combating malaria and other insect-borne diseases.
Scientists may be able to entomb the malaria parasite in a prison of its own making, researchers at are reporting. The malaria parasite is among the world’s deadliest pathogens.
The same federal scientist who recently found forgotten samples of smallpox at a federal lab also uncovered over 300 additional vials, many bearing the names of highly contagious viruses and bacteria.
Mycobacterium tuberculosis, the organism that causes tuberculosis in humans, also afflicts Asian elephants. Diagnosing and treating elephants with TB is a challenge, however, as little is known about how their immune systems respond to the infection. A new study begins to address this knowledge gap, and offers new tools for detecting and monitoring TB in captive elephants.
When it comes to infecting humans and animals, bacteria need a helping hand. Biochemists have found the helping hand: groups of tiny protein loops on the surface of cells.
Being sick due to an infection can make us feel lousy. But what must the ecosystem of bacteria, or microbiota, colonizing our guts be going through when hit with infection? A new study has utilized unique computational models to show how infection can affect bacteria that naturally live in our intestines.
Bacterial Respiratory Tract Colonization Prior to Catching the Flu May Protect Against Severe IllnessJuly 11, 2014 1:10 pm | News | Comments
Many studies have shown that more severe illness and even death are likely to result if you develop a secondary respiratory infection after developing influenza. Now, however, a team of researchers based at The Wistar Institute has determined that if you reverse the order of infection, the bacteria Streptococcus pneumoniae (often called pneumococcus) may actually protect against a bad case of the flu.
Health researchers from the University of Copenhagen have uncovered new knowledge about the immune system in a mouse study, which indicates that natural birth improves the immune system of the pups. A number of studies suggest that children delivered by Caesarean section have a different intestinal flora than children delivered by natural birth. But it is still unknown why this is the case and what it means for the immune system.
A Mississippi girl born with the AIDS virus and in remission for years despite stopping treatment now shows signs that she still harbors HIV — and therefore is not cured.
Scientists have discovered that measles and Nipah viruses manipulate the phosphorylation state of the immune sensor MDA5, keeping it inactive while the virus enters cells and replicates.
In an era of increasing concern about the prevalence of antibiotic-resistant illness, researchers have identified a promising new pathway to disabling disease: blocking bacteria’s access to iron in the body.
As climate change shifts the geographic ranges in which animals can be found, concern mounts over the effect it has on their parasites. Does an increased range for a host mean new territory for its parasites as well? Not necessarily, says a team of UC Santa Barbara scientists.
Researchers from North Carolina State University and the University of Minnesota have found for the first time that genetically identical strains of bacteria can respond very differently to the presence of sugars and other organic molecules in the environment, with some individual bacteria devouring the sugars and others ignoring it.
Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics—and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids. Their study found the nanopyramids can flag bacteria and kill more of them than medicine alone.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on the possible double-punch of tick bites and how to control and undo years of heart damage.
A government scientist cleaning out an old storage room at a research center near Washington made a startling discovery last week- decades-old vials of smallpox packed away and forgotten in a cardboard box.
An AIDS research team at Iowa State University will not get the final $1.38 million payment of a National Institutes of Health five-year grant after a team member admitted last year to faking research results.
