Strategy proven for botulism; may lead to improved therapies for many toxins and some chronic diseases.
A new study finds that while nevirapine works well to prevent mother-to-child HIV transmission, a single dose of nevirapine in infected pregnant women can trigger resistance to some forms of the AIDS-drug cocktail known as combination antiretroviral treatment (ART). This nevirapine-induced resistance fades after about 12 months and no longer hinders ART, say UAB researchers working in Zambia.
WSU receives federal grant to target genetics of E. coli in cattle.
How do you study-and try to cure in the laboratory-an infection that only humans can get? A team led by Salk Institute researchers does it by generating a mouse with an almost completely human liver. This "humanized" mouse is susceptible to human liver infections and responds to human drug treatments, providing a new way to test novel therapies for debilitating human liver diseases and other diseases with liver involvement such as malaria.
Genetic interactions between avian H5N1 influenza and human seasonal influenza viruses have the potential to create hybrid strains combining the virulence of bird flu with the pandemic ability of H1N1, according to a new study.

A campaign that makes seasonal flu vaccinations for hospital staff free, convenient, ubiquitous and hard to ignore succeeds fairly well in moving care providers closer to a state of “herd” immunity and protecting patients from possible infection transmitted by health care workers, according to results of a survey at The Johns Hopkins Hospital.
A leading immunology research institute has validated the long-held and controversial hypothesis that antibodies – usually the “good guys” in the body’s fight against viruses – instead contribute to severe dengue virus-induced disease, the La Jolla Institute for Allergy & Immunology announced today. The finding has major implications for the development of a first-ever vaccine against dengue virus, a growing public health threat which annually infects 50 to 100 million people worldwide, causing a half million cases of the severest form.
The results of an innovative study to understand what factors may influence who contracts tuberculosis (TB)/HIV co-infection in San Diego show a significant shift in the ethnic makeup of the disease, with the majority of cases now coming from the Hispanic community.
A team of scientists, led by a virologist from the University of California, San Diego’s Center for AID Research (CFAR), has discovered the origin of strains of human immunodeficiency virus (HIV) among men who have sex with men. The study, which may be important in developing prevention strategies for HIV, will appear in Science Translational Medicine on February 10, 2010.

As a pivotal paper linking childhood vaccinations to autism is discredited, a new study finds no evidence that the measles vaccine—given alone or as part of a combined measles, mumps, and rubella (MMR) vaccine—increases the risk of autism in children. The study appears in The Pediatric Infectious Disease Journal.
Dana-Farber Cancer Institute and the Sanford-Burnham Medical Research Institute have signed a license agreement with Genentech, a wholly owned member of the Roche group, and Roche, that grants the companies exclusive rights to manufacture, develop and market human monoclonal antibodies to treat and protect against group 1 influenza viruses.
The first head-to-head comparison of therapeutic monoclonal antibodies produced from plants versus antibodies produced from mammalian cells has shown that plant-produced antibodies fight infection equally well. The less expensive approach shows potential for treating disease in developing nations.
1) Cigarette smokers may have heightened cancer awareness, making them more open to vaccination for cancer prevention; 2) Physical activity also associated with greater vaccine acceptance; 3) Users of complementary and alternative therapy are less accepting of vaccine.
The state of Michigan, which used a five-step checklist developed at Johns Hopkins to virtually eliminate bloodstream infections in its hospitals’ intensive care units , has been able to keep the number of these common, costly and potentially lethal infections near zero — even three years after first adopting the standardized procedures. A report on the work is being published in the February 20 issue of BMJ (British Medical Journal).

A research team led by Mei Hong of Iowa State University and the Ames Laboratory has determined where an antiviral drug binds to and blocks a channel necessary for the flu virus to spread. The researchers also discovered that the drug spins in the channel, meaning there could be room for developing drugs that do a better job blocking the channel and stopping the flu. The findings are published in the Feb. 4 issue of the journal Nature.
Results from clinical trials conducted in Tanzania show that a new vaccine against tuberculosis, Mycobacterium vaccae (MV), is effective in preventing tuberculosis in people with HIV infection.

Malaria causes more than two million deaths each year, but an expert multinational team battling the global spread of drug-resistant parasites has made a breakthrough in the search for better treatment. Better understanding of the make-up of these parasites and the way they reproduce has enabled an international team, led by John Dalton, a biochemist in McGill’s Institute of Parasitology, to identify a plan of attack for the development of urgently needed new treatments.

HIV infection or the treatments used to control it are prematurely aging the brain, researchers at have found. Blood flow in the brains of HIV patients is reduced to levels normally seen in uninfected patients 15 to 20 years older.
A viral infection is like an uninvited, tenacious houseguest in the cell, using a range of tricks to prevent its eviction. Researchers at the Salk Institute for Biological Studies have identified one of the key proteins allowing herpes simplex virus (HSV) DNA to fly under the radar of their hosts' involuntary hospitality.
Systemic pre-exposure administration of antiretroviral drugs provides protection against intravenous and rectal transmission of HIV in mice with human immune systems, according to a new study published January 21, 2010 in the online journal PLoS ONE. “These results provide evidence that a universal approach to prevent all forms of HIV transmission in all settings might be possible,” said J.

"Immunization is the best defense we have to prevent the spread of H1N1 influenza in the months ahead," says Richard Whitley, the director of the University of Alabama at Birmingham (UAB) Division of Pediatric Infectious Diseases and current president of the Infectious Diseases Society of America (IDSA). The reminder comes during National Influenza Vaccination Week, Jan. 10-16.
New schedule includes formal recommendations that children older than 6 months get the H1N1 influenza vaccine to guard against swine flu, and that combination vaccines are generally preferred over separate injections, says UAB's David Kimberlin, a member of the AAP's infectious disease committee.
It is not too late for those who have not been immunized against the novel H1N1 influenza A virus or seasonal influenza to protect themselves from a potentially serious and possibly fatal illness. “Flu is very unpredictable,” said Dr. Peter Wenger, an associate professor in the departments of Preventive Medicine & Community Health and Pediatrics at the UMDNJ-New Jersey Medical School. Another wave of widespread flu illness could occur as the winter progresses, possibly even into March or April, he added. “The prudent course is to protect yourself and those around you, and the best way to do that is through vaccination,” he said. National Influenza Vaccination Week , which runs Jan. 10-16, 2010, is a great time to take action.
Lessons learned from the first 13 children at Johns Hopkins Children’s Center to become critically ill from the H1N1 virus show that although all patients survived, serious complications developed quickly, unpredictably, with great variations from patient to patient and with serious need for vigilant monitoring and quick treatment adjustments.
