Closing schools for less than two weeks during an influenza epidemic has no effect on infection rates, according to a study by researchers at the University of Pittsburgh, RTI International and the Allegheny County Health Department.
Researchers at the University of North Carolina at Chapel Hill have discovered that a single atom – a calcium, in fact – can control how bacteria walk. The finding identifies a key step in the process by which bacteria infect their hosts, and could one day lead to new drug targets to prevent infection.
Scientists recently discovered a simple gene mutation that decreases the chance people will get a flesh-eating disease called necrotizing fasciitis. Further, they proved that inactivating this section of the gene lessens the devastating disease in humans.
Cleaning hands with either soap and water or alcohol-based hand sanitizers can effectively prevent the spread of bacterial or viral infections.
Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients. And at the molecular level, just as at the high school gym level, it's a job that usually requires a lot of energy.
Researchers are investigating whether viruses that have adapted to higher temperatures – similar to increases due to global warming – can jump species more easily. Their results could shed light on the characteristics of H1N1-like viruses in a world of increasing temperatures.
Brazilian researchers have performed the first-ever autopsy study to examine the precise causes of death in victims of the H1N1 swine flu.
Older adults with long-term exposure to higher levels of pollution are at higher risk for hospitalization for pneumonia, according to researchers in Canada.
A study suggests that a new compound, one on the threshold of final testing in humans, may be more potent and safer for treating “bird flu” than the antiviral drug best known by the trade name Tamiflu.
A new study is casting doubt on a provocative theory that explains why tuberculosis can lie dormant in some patients for years.
Investigators have identified 295 human cell factors that influenza A strains must harness to infect a cell, including the currently circulating swine-origin H1N1.
Investigators have identified host factors that help multiple influenza strains thrive and which could be targeted for new antivirals.
One dose of vaccine may be effective to protect infants and children and reduce transmission of the H1N1 virus, according to a study in JAMA, published online today because of its public health implications. The study will appear in the January 6 print edition of the journal.
Scientists have identified a strain of antibiotic-resistant tuberculosis that thrives in the presence of rifampin, a front-line drug in the treatment of tuberculosis. The researchers determined that the bacteria grew poorly in the absence of the antibiotic rifampin and better with it.
Researchers at Binghamton University, State University of New York, have identified three key regulators required for the formation and development of biofilms. The discovery could lead to new ways of treating chronic infections.
The NJ Poison Control Center's Hotline is telling callers there is no danger if their children received the H1N1 vaccine that was recalled by Sanofi Pasteur, according to Bruce Ruck, Pharm.D., UMDNJ Director of Drug Information and Professional Education.
At a time when an infectious disease makes international headlines, sending Americans to wait in line for hours for a standard dose of H1N1 vaccine, the Organization for the Study of Sex Differences (OSSD), the scientific partner of the Society for Women’s Health Research announces the release of Sex Hormones and Immunity to Infection, a reference resource for researchers, clinicians, teachers, and PhD students in endocrinology and immunology.
Researchers from the La Jolla Institute for Allergy & Immunology will take aim at several of the world’s most dangerous infectious diseases – tuberculosis, malaria and dengue virus -- in a five-year, $18.8 million federally-funded set of projects seeking to make new inroads toward vaccines against the disorders.
Despite a 100-fold increase in H1N1 influenza cases in the Seattle area during spring 2009, an aggressive infection control program to protect immunocompromised cancer patients and thorough screening measures resulted in no corresponding increase in H1N1 cases among the total patient population at the Seattle Cancer Care Alliance, according to a new study by researchers and physicians at Fred Hutchinson Cancer Research Center and the SCCA.
An international team of Canadian and Spanish scientists have found the first potential immunological clue of why some people develop severe pneumonia when infected by the pandemic H1N1 virus.
