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

DNA analysis of essential marine microbe yields surprises: Tiny organism plays critical role in ocean

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

Human Genetic Vulnerabilities May Underlie Infectious Diseases, Scientist Argues

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...

Suppose there were an anthrax attack, and suppose you had antibiotics...

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

Plant Buffers May Limit Spread of Antibiotics in Animal Waste

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

Journal Club: Get Rid of False-Positives in 16s rDNA PCR

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

Potentially Deadly Infection Linked to Frequent Cow Exposure

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 finds salmonella in chips, E. coli O157:H7 in Toll House cookie dough

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

Antibiotic protects hearing in young mice, study finds

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

FBI closes anthrax case, says scientist was killer

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 Partner Up With Heat-Resistant Algae

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

Fight HIV with HIV: 'safe' virus proposed as vaccine

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

A Prophage Masquerade

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

New vaccine storage technology could revolutionize immunization in the developing world

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

Biologists discover how biological clock controls cell division in bacteria

A team of biologists has unraveled the biochemistry of how bacteria so precisely time cell division, a key element in understanding how all organisms from bacteria to humans use their biological clocks to control basic cellular functions.

The discovery, detailed in the February 19 issue of th... Read More

Roundworm Bacteria Research Shows Promise for Development of New Antibiotics

In a finding that bodes well for the development of new human antibiotics, Harvard researchers have determined the identity of the trigger that causes roundworm bacteria to excrete virulent substances.

Harvard Medical School Professor Jon Clardy teamed with researchers in the department of bi... Read More

Fighting Back Against a Superbug

When a bacterium evolves resistance to a particular antibiotic, it's problematic. When it evolves defenses against antibiotics in general, as Pseudomonas aeruginosa has done, it's terrifying. But now researchers have devised an antibiotic that attacks the germ in a completely new way that appear... Read More

DNA Precipitation: Ethanol vs. Isopropanol - a discussion of best practices
