The orientation of antibody binding to bacteria can mean life or death to the bug, according to a study published in The Journal of Experimental Medicine. These findings may help explain why these bacteria cause millions of localized infections, but more serious, systemic blood infections are rare.
Tips and myths about the flu are debunked - stomach cramps rather than laughter will have holidaymakers stomachs shaking like a bowl full of jelly as the flu season hits early and hard, says Jorge Parada, chair of infection control at Loyola University Health System.
Just 20 percent of people infected with the hepatitis C virus (HCV) begin the recommended treatment regimen and less than 5 percent go on to successfully overcome the virus, according to a new review in General Hospital Psychiatry.
Montefiore Medical Center experts say it’s not too late to benefit from a flu vaccine despite the earliest arrival of the influenza season in decades. This year's epidemic is starting early and could be significantly more severe than last year.
Restaurant dishes and silverware may be an overlooked place where people can catch stomach viruses. While the current industry guidelines for cleaning dishware used in public settings are effective at neutralizing bacteria, researchers at The Ohio State University found that they appear to fall short of eliminating norovirus - the leading cause of epidemic gastroenteritis and the major cause of foodborne illness worldwide, responsible for at least 50% of all gastroenteritis outbreaks in the United States.
A Virginia Tech team of environmental engineers have shown for the first time the relationship between the influenza A virus viability in human mucus and humidity over a large range of relative humidities, from 17 percent to 100 percent.
Researchers have discovered a toxin in community-associated MRSA that kills human cells.
Road networks and geographic factors affecting "spatial accessibility" have a major impact on the spread of HIV across sub-Saharan Africa, according to a study published online by the journal AIDS, official journal of the International AIDS Society. AIDS is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
A Kansas State University research team has resolved a 40-year-old debate on the role of iron acquisition in bacterial invasion of animal tissues. The findings suggest new approaches against bacterial disease and new strategies for antibiotic development.
College football and basketball games may provide more than a way for students to show school spirit – they could help prevent the flu. According to a new study by researchers at Wake Forest Baptist Medical Center, colleges and universities should implement new or improved influenza vaccine strategies, such as giving flu shots at sporting events or during campus-wide, day-long campaigns, to increase the number of their students who get the annual flu vaccine.
Electrically spun cloth with nanometer-sized fibers show promise as a cheap, versatile platform to simultaneously offer contraception and prevent HIV. New funding from the Bill & Melinda Gates Foundation will further test the system's versatility and feasibility.
Virginia Tech researchers have discovered how a common diarrhea-causing bacterium sends the body’s natural defenses into overdrive, actually intensifying illness while fighting infection.
Turkey releases non-native guineafowl to eat ticks that carry deadly Crimean-Congo hemorrhagic fever. Yet research suggests guineafowl eat few ticks, but carry the parasites on their feathers, possibly spreading the disease they were meant to stop, says a Turkish biologist working at the University of Utah.
Vanderbilt biologists have discovered mosquitoes possess a previously unknown mechanism for destroying pathogens that takes advantage of the peculiarities of the insect’s circulatory system to increase its effectiveness.
In the case of such pathogens as hepatitis C, HIV, and malaria, the body and the pathogen essentially fight to a prolonged stalemate, neither able to gain an advantage. Over time, however, the cells become “exhausted” and the immune system can collapse, giving the pathogen the edge. A new study is showing how that happens, suggesting a novel approach that might shift the balance of power in chronic infections.
Saint Louis University's Center for Vaccine Development is conducting a clinical trial that could help identify the most promising tuberculosis vaccines for future study.
Scientists have developed a new system that adapts techniques used in weather prediction to generate local forecasts of seasonal influenza outbreaks. By predicting the timing and severity of the outbreaks as far as seven weeks in advance, the system can eventually help society better prepare for them.
University at Buffalo microbiologists studying bacterial colonization in mice have discovered how the very rapid and efficient spread of antibiotic resistance works in the respiratory pathogen, Streptococcus pneumoniae (also known as the pneumococcus). The UB team found that resistance stems from the transfer of DNA between bacterial strains in biofilms in the nasopharynx, the area just behind the nose.
The Ebola, Marburg and Lassa viruses are commonly referred to as emerging diseases, but leading scientists say these life-threatening viruses have been around for centuries.
