Neisseria meningitidis may cause septicemia (bacteria in the blood) and meningitis (infection of the membrane surrounding the brain), but the bacterium colonizes the nasopharynx in 10-20% of the human population without causing disease. Although understanding how the bacterium changes from a com... Read More
How often do you clean your hands? A study at Rhode Island Hospital observed staff on 161,526 occasions to monitor how often they cleaned their hands (ie, hand hygiene) between July 2008 to December 2012 and found that hand hygiene compliance improved from 60 percent to 89 percent.

Prevention of listeriosis relies on killing the causative agent, normally the bacterium Listeria monocytogenes, in dairies and other food-processing facilities. A number of disinfectants are used for this purpose, most often quaternary ammonium compounds such as benzalkonium chloride (BC). Unfor... Read More
The key to future HIV treatment could be hidden right in our own genes. Everyone who becomes infected deploys defense strategies, and some even manage to hold the virus at bay without any therapy at all. This immune system struggle leaves its mark within the pathogen itself – genetic mutations t... Read More

The protein LIMP-2 is vital for both humans and animals. If it is absent – due, for example, to a hereditary disease – substances of an unknown nature, probably lipids, accumulate in the organism. Up to now, scientists were unsure what the protein looks like and how exactly it functions. Privatd... Read More
Small shifts in agricultural practices can increase or reduce the risk of salmonella and listeria contamination on produce, new research shows.
For example, applying manure within a year of harvesting produce boosts the odds of contaminating a field with salmonella, which is the biggest singl... Read More

Researchers from Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) have identified obesity as a possible risk factor for clostridium difficile infection (CDI). These findings, which appear online in Emerging Infectious Diseases, may contribute to improved clinical surve... Read More
Gone are the days when bacteria were thought to just grow and divide and not bother to converse with one another. That simple idea has produced mountains of data and most of what we know about bacterial physiology is based on this notion. It turns out, as we know now, that this is an oversimplif... Read More
