Cold sore virus increasing cause of genital herpes and 'strongly associated' with early start to sex
Genital herpes due to HSV-1 - the herpes simplex virus primarily associated with cold sores on the mouth - is strongly associated with an early start to sex, suggests research in Sexually Transmitted Infections. And its prevalence is increasing, say the authors. The findings are based on blood samples and details of sexual behaviour from 869... view more... (2002-09-30)
Common Cold No More Frequent In People With Asthma - But Symptoms Are More Severe (p 831)
People with asthma are not at an increased risk of having a common cold, but are more likely to develop more severe respiratory symptoms if infected with the cold virus, conclude authors of a UK study in this week's issue of THE LANCET. Rhinoviruses are the most frequent cause of the common cold. It has long been thought that people with asthma... view more... (2002-03-06)
Lower Social Class Linked To Increased Risk Of Postoperative MRSA Infection' (p 706)
Results of a UK study in this week's issue of THE LANCET suggest that people from the poorest socioeconomic backgrounds could be up to seven times more likely to get postoperative infection with meticillin-resistant Staphylococcus aureus (MRSA) than people from affluent social groups. This heightened risk is more likely to be a result of increased... view more... (2004-02-25)
Heavy drinking increases risk of infection after surgery
Research news from the British Journal of Surgery 17 October 2003: Nosocomial infection is a risk faced by any patient undergoing general surgical procedures. A recent study published in the British Journal of Surgery reveals that some patients increase this inevitable risk to themselves and others through regular, heavy drinking prior to hospital... view more...

Fears about complications shouldn't drive antibiotic prescribing
Antibiotics are not justified to reduce the risk of complications after upper respiratory tract infection, sore throat, or ear infection, finds a study published on bmj.com today. view more (2007-10-19)
First parasitic nematodes reported in biofuel crops
Researchers at the Energy Biosciences Institute (EBI) at the University of Illinois have discovered widespread occurrence of plant-parasitic nematodes in the first reported nematode survey of Miscanthus and switchgrass plants used for biofuels. view more (2010-03-18)
Montreal researchers identify defects of immune cells
Researchers at Université de Montréal and the Institut de recherches cliniques de Montréal (IRCM) have successfully identified a defective immune cell population that determines susceptibility to candidiasis, a common and often debilitating infection in individuals infected with the human immunodeficiency virus (HIV). view more (2006-06-22)
How mosquitoes could teach us a trick in the fight against malaria
The means by which most deadly malaria parasites are detected and killed by the mosquitoes that carry them is revealed for the first time in research published today (5 March) in Science Express. The discovery could help researchers find a way to block transmission of the disease from mosquitoes to humans. view more (2009-03-06)
The bowels of infection
Current research suggests that latent cytomegalovirus (CMV) infection may exacerbate inflammatory bowel disease (IBD). The related report by Onyeagocha et al, "Latent cytomegalovirus infection exacerbates experimental colitis," appears in the November 2009 issue of The American Journal of Pathology. view more (2009-10-21)
Antibiotic not sufficient for serious eye infection in communities with high disease prevalence
Treating trachoma, an eye infection that can lead to blindness, with a single mass antibiotic distribution in Ethiopian communities with high prevalence of infection is not effective in eliminating the disease. view more (2006-03-08)
Bacterial Protein Shows Promise in Treating Intestinal Parasites
Scientists at the University of California, San Diego and Yale University have discovered that a natural protein produced by Bacillus thuringiensis, a bacterium sprayed on crops by organic farmers to reduce insect damage, is highly effective at treating hookworm infections in laboratory animals. view more (2006-09-26)
1 of life's most common compounds causes allergic inflammation
The beetle's back and the crab's shell owe their toughness to a common compound called chitin that now appears to trigger airway inflammation and possibly asthma, UCSF scientists have found. view more (2007-04-23)
Study shows parasites outweigh predators
In a study of free-living and parasitic species in three estuaries on the Pacific coast of California and Baja California, a team of researchers from the University of California, Santa Barbara, the United States Geological Survey, and Princeton University has determined that parasite biomass in those habitats exceeds that of top predators, in... view more...

Vaccine hope for malaria
One person dies of it every 30 seconds, it rivals HIV and tuberculosis as the world's most deadly infection and the vast majority of its victims are under five years old. view more (2007-05-24)
First national programme to combat Schistosomiasis launched in Uganda
The first national programme to tackle schistosomiasis in sub-Saharan Africa will be launched today in Uganda by President Yoweri Kaguta Museveni. Schistosomiasis, also known as Bilharzia, is a chronic parasitic disease that affects around 200 million people worldwide, causing liver damage and potentially death. The Ugandan initiative is the... view more... (2003-03-04)
Swine flu: What does it do to pigs?
The effects of H1N1 swine flu have been investigated in a group of piglets. Scientists writing in BioMed Central's open access Virology Journal studied the pathology of the virus, finding that all infected animals showed flu-like symptoms between one and four days after infection and were shedding virus two days after infection. view more (2009-05-11)
Parasitic plants sniff out hosts
Parasitic plants do not haphazardly flail about looking for a host but sense volatile chemicals produced by other plants and identify potential hosts by their emissions. view more (2006-09-29)
New screening strategy for detection of chagas disease in children
A new targeted screening strategy could make the diagnosis and treatment of Chagas disease more feasible in low-resource settings, concludes a new study, publishing on December 26, 2007, in the open-access journal PLoS Neglected Tropical Diseases. view more (2007-12-26)
More Frequent Ivermectin Treatment Could Reduce Symptoms Of Disease Responsible For River Blindness
Authors of a study in this week's issue of THE LANCET propose that more frequent drug therapy with ivermectin could reduce symptoms of the parasitic disease onchocerciasis, which affects around 18 million people in sub-Saharan Africa and Latin America and can lead to river blindness. The parasitic worms (Onchocerca volvulus)... view more... (2002-07-17)
Plants tell caterpillars when it's safe to forage
The world is filled with cues that could influence the daily feeding patterns of an organism. Many plants, for example, respond to foraging damage by releasing specialized chemical signals-volatile organic compounds that evaporate in the air-that attract the forager's natural enemies. view more (2006-05-16)
