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.
A renowned Alabama researcher on antiviral therapies designed to fight infections in children and adults is the new president of the Infectious Diseases Society of America (IDSA). UAB’s Richard Whitley, M.D., is a distinguished professor of pediatrics, microbiology, medicine and neurosurgery who also serves on the working group providing recommendations to President Barack Obama on federal responses to H1N1 and pandemic flu.
John L. Johnson, M.D., Professor of Medicine at Case Western Reserve University School of Medicine and pulmonologist at University Hospitals Case Medical Center has been awarded a 10 year, $19.7M contract from the U.S. Centers for Disease Control and Prevention (CDC) as an international clinical trials site for the Tuberculosis Trials Consortium (TBTC).
Researchers have discovered how the parasite Trypanosoma cruzi, which causes Chagas’ disease, prolongs its survival in infected cells. A protein on the parasite activates the enzyme Akt, which blocks cell death signals, preventing cell destruction and parasite elimination. Chagas’ disease affects some 8 to 11 million people throughout Latin America and even the United States.
An independent lab report demonstrated that BIOGUARD™ barrier gauze dressings exhibit greater than 99.9% inactivation rates against swine flu virus after exposure for 24 hours.
Infection with the H1N1 virus, or swine flu, causes more life-threatening complications than seasonal flu in children with sickle cell disease, according to research from Johns Hopkins Children’s Center. The findings, to be presented on Dec. 7 at the annual meeting of the American Society of Hematology, warn parents and caregivers that such children are more likely to need emergency treatment and stays in an intensive-care unit.
