A water ban that had hundreds of thousands of people in Ohio and Michigan scrambling for drinking water has been lifted, Toledo's mayor announced Monday.
The nation's top infectious disease official says there's hope that a vaccine against Ebola will be available as early as next July. Dr. Anthony Fauci of the National Institutes of Health says such a preventive vaccine has been successfully tested with monkeys.
Harnessing a natural process in the body that pumps lethal doses of copper to fungi and bacteria shows promise as a new way to kill infectious microbes, a team of scientists report.
University of Washington bioengineers have discovered a potentially faster way to deliver a topical drug that protects women from contracting HIV. Their method spins the drug into silk-like fibers that quickly dissolve when in contact with moisture, releasing higher doses of the drug than possible with other topical materials such as gels or creams.
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.
Microorganisms can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs. Now, a new study has shown that microorganisms can use a temporary silencing of drug targets to gain the benefits of drug resistance without the commitment.
Nigerian health authorities raced to stop the spread of Ebola on Saturday after a man sick with one of the world's deadliest diseases brought it by plane to Lagos, Africa's largest city with 21 million people.
When it comes to preventing the spread of germs, maybe the president is on to something with his fondness for fist bumps. The familiar knocking of knuckles spreads only one-twentieth the amount of bacteria that a handshake does, researchers report.
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.
