We dump huge amounts of plastic waste into the ocean every year, much of it ending up as microplastic – fragments less than 5 millimetres across. Famously, much of it has gathered in the Great Pacific Garbage Patch, and it may harm animals that inadvertently swallow it.
Now, it appears that m... Read More
Despite surgeons’ best efforts, bacteria often manage to sneak onto medical implants such as bone screws, where they can cause severe infections. Research published today in Nature Communications suggests that using fluorescent antibiotics could reveal such infections before they become too seve... Read More
Michael Pollan, food author, activist and journalism professor, wrote this week’s cover story about the organisms with which we share our bodies — and how we’re dependent on them. His book “Cooked: A Natural History of Transformation” came out last month. His last article for the magazine was ab... Read More
In order to isolate, study and efficiently treat a bacterial outbreak, it is vital to be able to grow, store and identify the particular strains of bacteria that cause the disease. While this can be a fairly simple task in a well stocked laboratory, it’s a lot harder to achieve out in the field,... Read More
There was much written concerning the research published earlier this month in Science, where researchers from China’s Harbin Veterinary Research Institute reported creating an avian H5N1 (highly pathogenic) and pandemic 2009 H1N1 (easily transmissible) hybrid, that according to them, achieved ...

Human papillomavirus (HPV) can damage chromosomes and genes directly, researchers report in a new study. HPV is a virus that can cause anal, cervical, head and neck cancers, and according to experts, it produces two viral proteins (E6 and E7) that are involved in the development of those diseas...

Amoeba eat bacteria and other human pathogens, engulfing and destroying them – or being destroyed by them, but how these single-cell organisms distinguish and respond successfully to different bacterial classes has been largely unexplained.
In a report in the journal Current Biology, research... Read More
Stephen Crohn, a man best known for staying alive during the early days of the AIDS epidemic, died Aug. 23 at age 66. Throughout his lifetime, the New York artist helped researchers uncover vital clues about HIV and how to stop it.
Crohn's partner was one of the first people to die from AIDS ... Read More
The bacterium Pseudomonas aeruginosa needs iron to establish and maintain a biofilm in the lungs of cystic fibrosis patients, and therapies have been proposed to deprive the bacteria of this necessary element. However, these techniques may not work, according to a new study published in mBio®, t... Read More
Robert Koch is one of the key figures in early bacteriology, helping develop culture techniques (e.g. solid media), critical reasoning (e.g. Koch’s postulates), and disease etiology (e.g. cholera and tuberculosis). He also published the first photomicrographs of bacteria (Figure 1A) in his 1877 ... Read More
SAN FRANCISCO – Swallowing pills containing a concentrate of fecal bacteria successfully stops recurrent bouts of debilitating Clostridium difficile (C. diff) infection by rebalancing the bacteria in the gut, suggests a study being presented at the IDWeek 2013™ meeting today.
Infection from C... Read More
Trypanosoma brucei, the parasite that causes sleeping sickness, is transmitted to mammals by the tsetse fly, and must adapt to the divergent metabolisms of its hosts. A new study shows how it copes with the frugal diet offered by the fly.
Sleeping sickness is a deadly human disease in tropica... Read More
Critically ill patients with the pandemic H1N1 influenza who received triple the standard dose of the influenza drug oseltamivir were 7 times more likely to completely clear the virus from their system in 5 days than those who received the standard dose. This discussion addresses the healthcare... Read More
Salmonella is a major cause of human diarrhoeal infections and is frequently acquired from chickens, pigs and cattle, or their products. Around 94 million such infections occur in people worldwide each year, with approximately 50,000 cases in the UK per annum.
In a BBSRC-funded collaboration ... Read More
A common ingredient in antibacterial soap can be found in some people's noses, and the presence of this ingredient could be promoting the colonization of Staph bacteria, according to a small new study in the journal mBio.
Researchers from the University of Michigan found triclosan in the nasa... Read More
On a sunny day in 1998, Maura Gillison was walking across the campus of Johns Hopkins University in Baltimore, Maryland, thinking about a virus. The young oncologist bumped into the director of the university's cancer centre, who asked politely about her work. Gillison described her discovery of... Read More
There have been several outbreaks of highly pathogenic H5N1 avian influenza viruses affecting humans over the past decade, the causes of which have been limited to direct human contact with infected birds. Recent publications suggest that a very small number of coding mutations in the viral HA g... Read More
One man's irrepressible body odor was the result of a bacterial infection of his armpit hair, according to a new report of the case.
The 40-year-old man told his doctors he'd had armpit odor and "dirty" armpit hair for the last four years.
