World Health Organisation (WHO) guidelines for preventing the spread of tuberculosis through air travel are largely a waste of time and resources, an expert said.
The WHO recommendations, set down in 2006 and 2008, urge health watchdogs to trace and screen passengers who have sat for longer t... Read More
So-called 'cryptic' bacterial genes that preside over the production of medically important compounds can be switched on using environmental triggers, German scientists have shown. The researchers used soil extracts to persuade a Clostridium species to produce a hitherto unknown antibiotic that... Read More
Broad spectrum antibiotics are available that act against a wide range of bacteria, including both gram-positive and gram-negative species. In contrast, our antiviral arsenal is exceedingly specific. Nearly all the known antivirals block infection with one or two different viruses. The discovery... Read More
On episode #70 of the podcast This Week in Virology, Vincent, Dickson, and Alan consider a broad spectrum antiviral against enveloped viruses, how a plant virus induces chemical signals in the host ... Read More
Vaccination programs against whooping cough may not be fully effective because the bacteria that cause the disease have evolved new strains, a University of New South Wales study has found.
A team of Australian scientists has shown for the first time that two of the most common strains of the... Read More
The FDA announced yesterday a recall by Queseria Bendita of certain cheese products due to fears that the products are contaminated by Listeria monocytogenes. The potentially lethal bacteria has been found at the Queseria Bendita facility and in samples of unopened, recalled product.

As part of her introduction to On-Site Dentistry, where she has long received her dental care, she said dentists and hygienists explained the importance of oral hygiene, citin... Read More
Genome analysis of an important microbe sheds light on the unexplained puzzle of how oceans maintain a healthy balance of nutrients, say scientists at UC Santa Cruz.
While Jonathan Zehr, a marine microbiologist at UCSC, discovered the microbe in 1998 near Hawaii, the tiny organism has proved ... Read More
Rockefeller University's Jean Laurent Casanova spoke on the connection between genetics and infectious diseases at the 2010 annual conference of the American Association for the Advancement of Science (AAAS) on Friday, February 19, focusing on current findings and putting them in context in this...

Such is the scenario recently presented to a national sample of Americans by Harvard University researchers ....
First, respondents were told to imagine that some residents of their town had become ill from what was believed to be inhalation anthrax, that some had died, and that many more lik... Read More
Research by scientists at the University of Missouri Center for Agroforestry suggests that buffer strips of grasses and other plants can trap and break down veterinary antibiotics in manure fertilizers.
Buffer strips have already demonstrated that they can be effective in protecting water qua... Read More
How many of you run into problems of false- positive PCR or lack of sensitivity in qPCR when trying to use 16S primers because of the background genomic DNA in your PCR enzyme mixes? At MO BIO Labs, we do.
This article is a review of a new paper in the Journal of Microbiological Methods (Novem... Read More
A common bacteria found in many healthy adult females that can cause life-threatening infections when passed to newborns could be introduced to some women through frequent contact with cows, according to a research team led by a Michigan State University pediatrician.
The recently published f... Read More
Nestle chocolate morsels made in Wisconsin have tested positive for salmonella, according to a company spokeswoman.
This news follows a statement from the company in January that it again found a potentially fatal bacteria in its Toll House cookie dough.
There was no outbreak -- or recall ... Read More
Researchers at Washington University School of Medicine have found that the antibiotic Kanamycin (KM), which was previously believed to damage ears, actually has a protective effect against hearing loss in young mice when used in low doses.
KM is an antibiotic used to isolate bacteria and tre... Read More
Wrapping up one of its most vexing investigations, the FBI concluded that Army scientist Bruce Ivins acted alone in the 2001 anthrax mailings that killed five people and further unnerved a nation still reeling from the 9/11 attacks.
The agency formally closed the case Friday, ending the long... Read More
Corals around the world, already threatened by pollution, destructive fishing practices and other problems, are also widely regarded as among the ecosystems likely to be first — and most — threatened with destruction as earth’s climate warms.
But there is reason to hope, researchers are repor... Read More
A company is planning to inject people with an HIV vaccine made of the deadly virus itself, albeit a deactivated version.
Vaccines against many viruses, including flu, are made from deactivated versions of those viruses, but such an approach was previously dismissed as too risky in the case o... Read More
Small Things Considered blogger Merry Youle has authored a post on the sequencing of Roseovarius nubinhibens. a bacterium that recently joined the group of about a thousand bacteria whose genomes have been sequenced. Researcher José González and colleagues in Mary Ann Moran's lab at the Universi... Read More
British researchers have devised a way to capture vaccines in a glass-like membrane composed of sugar, a feat that could eliminate the need for refrigeration of vaccines and revolutionize their distribution in the developing world. Tests have shown that the technique can preserve vaccines for as... Read More
