Biomedical engineering researchers have encapsulated two types of protein antigens in chitosan and demonstrated that the combined material enables or improves three important immune responses.
A baby born with the AIDS virus appears to have been cured, scientists announced Sunday, describing the case of a child from Mississippi who's now 2½ and has been off medication for about a year with no signs of infection. There's no guarantee the child will remain healthy, although sophisticated testing uncovered just traces of the virus' genetic material still lingering.
In a study, researchers demonstrated that certain cunning bacteria—including the type that causes tuberculosis—can pretend to be viruses when infecting humans, allowing them to hijack the body’s immune response.
A single mutation in the H5N1 avian influenza virus that affects the pH at which the hemagglutinin surface protein is activated simultaneously reduces its capacity to infect ducks and enhances its capacity to grow in mice according to new research.
Studying HIV-1, the most common and infectious HIV subtype, scientists have identified 25 human proteins ‘stolen’ by the virus that may be critical to its ability to infect new cells.
The overuse of antibiotics has created strains of bacteria resistant to medication, making the diseases they cause difficult to treat, or even deadly. Now, a research team has identified a weakness in at least one superbug that scientists may be able to medically exploit.
ASU's Cheryl Nickerson presented her research findings and charted the course for future investigations aboard the ISS at the 2013 annual meeting for the American Association for the Advancement of Science. read more
A team of scientists and surgeons are developing a new nasal spray from a marine microbe to help clear chronic sinusitis.
A patient being treated for a mysterious SARS-like virus has died, a British hospital said Tuesday. Queen Elizabeth Hospital in Birmingham, central England, said the coronavirus victim was also being treated for "a long-term, complex unrelated health problem" and already had a compromised immune...
Researchers have discovered how a new class of antimalarial drugs, spiroindolones, kills the malaria parasite, showing that the drugs block a pump at the parasite surface, causing it to fill with salt.
Researchers “cured” a strain of bacteria of its ability to resist an antibiotic in an experiment that has implications for a long-standing public health crisis.
A team of researchers has identified a protein with broad virus-fighting properties that potentially could be used as a weapon against deadly human pathogenic viruses such as HIV, Ebola, Rift Valley Fever, Nipah and others.
A pair of commentaries to appear in an upcoming issue of the journal Antimicrobial Agents and Chemotherapy highlight a debate within the public health community surrounding Centers for Disease Control and Prevention (CDC) recommendations for treatment of exposed individuals during last year’s fungal meningitis outbreak.
How, when and where a pathogen is transmitted between two individuals in a population is crucial in understanding and predicting how a disease will spread. New research has laid the foundation for a new generation of zoonotic disease spreading models, which could allow for more targeted prevention strategies.
Vaccines usually consist of inactivated viruses that prompt the immune system to remember the invader and launch a strong defense if it later encounters the real thing. However, this approach can be too risky with certain viruses, including HIV.
At least one in five people in countries for which data are available were infected with influenza during the first year of the 2009 H1N1 pandemic, according to a new study. The highest rates of infection were in children, with 47 per cent of those aged five to 19 showing signs of having caught the virus.
The $15 billion ornamental fish industry faces a global problem with antibiotic resistance, a new study concludes, raising concern that treatments for fish diseases may not work when needed – and creating yet another mechanism for exposing humans to antibiotic-resistant bacteria.
Researchers at The University of Texas at Austin have developed a menu of 61 new strains of genetically engineered bacteria that may improve the efficacy of vaccines for diseases such as flu, pertussis, cholera and HPV. The strains of E. coli are part of a new class of biological “adjuvants” that is poised to transform vaccine design.
Roy Curtiss wants to vaccinate children and animals alike in the far regions of the world from the most basic scourges of the Earth—typhoid fever, pneumonia, influenza, tuberculosis. But to do that, he must get them to swallow Salmonella-laced liquids.
A new process to make a one-time, universal influenza vaccine has been discovered by a researcher at Georgia State University. The researcher and collaborators have found a way to make the one-time vaccine by using recombinant genetic engineering technology that does not use a seasonal virus.
Hepatitis C virus has evolved to invade and hijack the basic machinery of the human liver cell to ensure its survival and spread. Researchers at the University of North have discovered how hepatitis C binds with and repurposes a basic component of cellular metabolism known as a microRNA to help protect and replicate the virus.
A fast growing, flesh-eating fungus killed 5 people following a massive tornado that devastated Joplin, Mo., according to two new studies based on genomic sequencing. Health officials should be aware of infections caused by the fungus Apophysomyces, according to the studies, which tracked 13 people infected by the pathogen during the Class EF-5 tornado.
A type of immune cell found in the small intestine plays a previously unsuspected role in monitoring antigens circulating in the bloodstream. The findings clarify how dendritic cells in the intestinal lining collect antigens from both intestinal contents and the circulation.
Mosquitoes are generally known as the sneaky pest that creeps up and bites, leaving you with an itchy bump on the surface of your skin. A nuisance to be sure, but in some areas of the world, they can be dangerous because the bugs carry malaria.
Bio-Rad Laboratories, Inc. and the American Red Cross announced that the U.S. Food and Drug Administration (FDA) has notified Bio-Rad that it may proceed with its Investigational New Drug (IND) study for the Bio-Rad Dengue NS1 Ag microplate assay
