Escherichia coli – a friendly and ubiquitous bacterial resident in the guts of humans and other animals – may occasionally colonize regions outside the intestines. There, it can have serious consequences for health, some of them lethal.
In a new study conducted in assistant professor Melha M... Read More
A new imaging technique for studying the structure of a childhood disease, respiratory syncytial virus (RSV), could provide scientists with the information they need to develop new antiviral drugs and perhaps even a vaccine to prevent severe infections.
By the time they’re two years old, most... Read More
A doctoral research project studying the bacterium Brucella pinnipedialis, which commonly occurs in hooded seals, found that this bacterium does not cause disease in hooded seals, as other Brucella bacteria do in other species.
The occurrence of the bacterium B. pinnipedialis in hooded seals ... Read More
The coronavirus that’s killed 71 people was detected in three camels in Qatar, supporting a thesis that the animals may be a source of human infection.
The dromedary camels were identified in a barn about 19 miles northwest of Doha owned by a 61-year-old man who was diagnosed in October with ... Read More
When studying bacteria it is quite easy to get fascinated with them as a laboratory specimen while forgetting the huge impact they can have in real life societies. I find the PLoS journal of Neglected Tropical diseases redresses that as it covers work with bacteria and parasites from the front l... Read More
Researchers at the Division of Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with an efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofib... Read More
The NDSU Department of Veterinary and Microbiological Sciences researchers discovered that B-phenylethylamine, or PEA, reduced the number of cells of Escherichia coli in a beef broth. PEA is a substance found in chocolate in trace amounts. Health food stores sell it in pill form to improve peopl... Read More
Slime molds may not have brains, but that isn't preventing some computer scientists from investigating them for their potential as novel, unconventional computers. A slime mold consists of a single cell containing millions of nuclei, and forms a network of protoplasmic tubes to move toward its f... Read More
A universal infant vaccination campaign in China has led the Hepatitis B virus (HBV) to more than double its rate of "breakout" mutations. These mutations may enable the virus to elude the vaccine, necessitating new vaccination strategies. Researchers at the Chinese Centers for Disease Control a... Read More
Vaccines, including those used in protecting against influenza, do not put a person at increased risk of Guillain-Barré syndrome despite wide-spread concerns, according to a Kaiser Permanente study published in the journal Clinical Infectious Disease.
The retrospective study spanned 13 years ... Read More
A serious infection that has been on the rise in hospital patients is being increasingly reported among people who work or spend time in doctor’s offices, clinics and other health-care settings. Caused by the bacterium Clostridium difficile, also known as C. diff, the infection can cause chronic... Read More
A team of scientists, led by researchers at The Wistar Institute, has determined that it might be possible to stimulate the immune system against multiple strains of influenza virus by sequentially vaccinating individuals with distinct influenza strains isolated over the last century.
Their r... Read More
Dungeons & Dragons co-creator Gary Gygax touched the lives of the people who loved his games. So when the legendary Dungeon Master died in March 2008, players around the world showed their thanks with heartfelt tributes –including naming a species of bacteria after him.
Arthronema gygaxiana i... Read More
Red squirrels at a National Trust reserve in Merseyside have shown signs of resistance to the pox virus that has blighted the species, say researchers.
Scientists from the University of Liverpool have studied the squirrels at the Formby site for four years.
They found that 10% of its squir... Read More
At least eight people came down with listeria -- and one of them died -- after, authorities believe, eating "Hispanic-style cheese."
The Centers for Disease Control and Prevention on Friday reported the outbreak, which has affected people only of Hispanic descent and living in California or M... Read More
In an advance for HIV vaccine research, a scientific team has discovered how the immune system makes a powerful antibody that blocks HIV infection of cells by targeting a site on the virus called V1V2. Many researchers believe that if a vaccine could elicit potent antibodies to a specific conse... Read More
U.S. malaria cases are at their highest level in four decades, mostly from Americans bringing home an unwelcome souvenir from their travels.
Malaria is not a big problem in the U.S. — there were only 1,925 cases in 2011, including five deaths. But cases were up 14 percent from the previous ye... Read More
New research finds significantly higher levels of infectious pathogens in water from faucet taps with aerators compared to water from deeper in the plumbing system. Contaminated water poses an increased risk for infection in immunocompromised patients. The study was published in the February iss... Read More
It is a well recognized uncommon cause of skin and nail infection of the hands and feet . Unlike Dermatophytosis these mould infections are not contagious. There are few reports of invasive infection caused by N. dimidiatum; most infections occurred in immunocompromised hosts. Arthrospores ar... Read More
Microbiologists from Trinity College Dublin have discovered that an identical protein is used differently by two species of bacteria to help them cope with distinct types of environmental stress. The discovery reveals an extraordinary level of versatility in the way different genes are ‘switched... Read More
