Typhoid fever is caused by systemic infection with Salmonella enterica Typhi. In contrast, infection with the closely related bacterium Salmonella enterica Thyphimurium is usually limited to the gut and causes less serious diarrheal disease. Research comparing the two pathogens reveals how S. Ty... Read More
As the year closes out, we enter into the giving seasons of a variety of traditions. Lurking among the more pleasant types of giving is the 2013 – 2014 flu season, a viral gift that often keeps on giving. To combat this, reminders about the potential dangers of influenza and the importance of va... Read More
Myxomycetes are well-known as true slime molds whose plasmodia are increadibly beautiful. Plasmodial culture is a such kind of hard-working steps in working with the species of Kingdom Protista. Interestingly, they can unpredictably "move" around water agar dishes. Furthermore, they are in progr... Read More
Aarhus University has developed a technology that uses the HIV virus as a tool in the fight against hereditary diseases - and in the long term, against HIV infection as well. The technology repairs the genome in a new and safer manner.
For the first time researchers have succeeded in altering... Read More
Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.
The finding, by infectious disease researchers at the University of Adelaide and The University of Queensland, opens the way for further work to des... Read More
A single dose of an investigational influenza drug was able to reduce the duration of fever and viral shedding, researchers said here.
In a combined analysis of two randomized placebo-controlled trials, the neuraminidase inhibitor peramivir (Rapivab), given by injection within 48 hours of sym... Read More
The delightful word 'oocyan' refers to the trait of blue-green eggshell color that occurs in native chickens of Chile (Mapuche fowl) and some of their descendants in North America and Europe, as well as certain Asian chicken breeds (e.g. Dongxiang, Lushi).
Oocyan is an autosomal dominant trai... Read More
Researchers at UCL have developed a new antibacterial material which has potential for cutting hospital acquired infections. The combination of two simple dyes with nanoscopic particles of gold is deadly to bacteria when activated by light - even under modest indoor lighting. And in a first for ... Read More
An international team of scientists from Singapore, Thailand, China and Australia has cracked the genetic code of the liver fluke parasite, Opisthorchis viverrini, using a unique DNA analysis technique developed at A*STAR’s Genome Institute of Singapore (GIS).
GIS’s DNA analysis technique ha... Read More
Saudi Arabia says one more person has died from a new respiratory virus related to SARS, bringing to 55 the number of deaths in the kingdom at the center of the outbreak.
The Health Ministry said Sunday that the 37-year-old man died in Riyadh. He was among 130 people who have been infected wi... Read More
A new biosensor quickly detects salmonella in food and can be easily customized to detect other types of bacteria—or even different strains for the same bacterium.
The process appears to easily outperform tests that are now standard in the food industry, according to researchers at Rice Unive... Read More
Research in mammals that aims to prevent future influenza pandemics raises ethical, public health concerns. Experiments creating dangerous flu strains that are transmissible between mammals pose too great a risk to human life from potential release, according to an editorial by researchers from...

From the discovery of the first Neanderthal skull in a Belgian cave in 1826, a bone of contention among Homo sapiens has been the extent of our relationship to Homo neanderthalis, who disappeared from the fossil record ~30,000 years ago. Like scrappy cousins we'd rather not claim, we've attempte... Read More
An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the green and yellow grainy spore formation in the center of the colony with exudate ...

They have us surrounded. Even inside the spaces we build for ourselves — like homes and offices — we are a tiny minority. Invisible bacteria, fungi, and viruses outnumber us by orders of magnitude. We will always be outnumbered, but we may have a say in which microbes we’re surrounded by, accord... Read More
George Washington had a collection of 476 kinds of pickles. To prevent scurvy, Christopher Columbus stocked pickles on the Niña, Pinta, and Santa Maria. Julius Caesar, believing pickles to be invigorating, added them to the Roman legions' diet. In 5000 BCE, the Babylonians were known for picklin... Read More
Recent salmonella outbreaks that sickened at least 523 people and sent dozens to the hospital underscore “serious weaknesses” in the U.S. Department of Agriculture’s oversight of poultry plants, according to a study released Thursday by the Pew Charitable Trusts, which also criticized the govern...

Getting the message out to the public that the microbial world is about much more than just diseases is a challenging topic, but one we should keep trying to improve on. There are many ways to do this, but as the saying goes, a picture is worth a thousand words, and most people don’t want to rea... Read More
In addition to storing films, optical discs can be used to detect microorganisms, toxins, allergens and tumoral biomarkers. Blu-ray technology has allowed researchers to develop a way to find out if a sample contains Salmonella or toxic substances. This simple and cheap analytical system may be ... Read More
A multi-disciplinary team from the University of Pennsylvania have published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells. This allows the researchers to analyze how cell-to-cell chemical connectio... Read More
