The health of most of the planet’s population is rapidly coming to resemble that of the United States, where death in childhood is rare, too much food is a bigger problem than too little, and life is long and often darkened by disability.
High blood pressure is now the leading “risk factor” f... Read More

Genus Serratia presents special problems of identification because of biochemical and morphological similarity to other genera of the Enterobacteriaceae, notably Klebsiella and Enterobacter. Serratia liquefaciens is an opportunistic pathogen which is capable of colonizing a wide variety of surfa... Read More
We've all been there. The holidays are approaching and there's that one person on our list for whom we have no idea what to give. It's a common problem that is usually resolved with the purchase of a gift card from a local retailer. From hardware stores to electronic shops to the bookstore, cons... Read More
The cervical cancer-causing virus may not fully clear from the body as once thought, experts say.
Many older women infected with the human papillomavirus (HPV) in their youth may not "clear" it from the body as completely as once thought, a new study suggests.
The research hints that HPV i... Read More
Understanding what happens to a soybean root hair system infected by symbiotic, nitrogen-fixing soil bacteria, Bradyrhizobium japonicum, could go a long way toward using this symbiosis to redesign plants and improve crop yields, benefitting both food and biofuel production. Because of their exte... Read More
Long ago, when life on Earth was in its infancy, a group of small single-celled algae propelled themselves through the vast prehistoric ocean by beating whip like tails called flagella. It's a relatively unremarkable tale, except that now, more than 800 million years later, these organisms have ... Read More
Unlike warthogs, likely to be considered beautiful only by their mother, the Verrucomicrobia (verruca means “wart, thus the warty bacteria; more about this later) have considerable appeal, be it morphological, physiological, or ecological. This is yet another phylum that owes its recognition to... Read More
please send input as to the nature of this. things I know: zoonotic, fast reproduction, fruiting bodies, possible yeast, cryptococcus? Dicty?some maturing cysts filled with red, one-two red dots. Read More
Students learn in many different ways than simply taking tests. In my Microbiology course, I have students write a length term paper (a "Microbiography"). As part of this process, students create one page "summaries" of their microbial topic, which I call "Nanobiographies." In this blog post,... Read More
Rare brain tumors emerging among raccoons in Northern California and Oregon may be linked to a previously unidentified virus discovered by a team of researchers, led by scientists from the University of California, Davis. Their findings, published today in the journal Emerging Infectious Disease... Read More
SLAC's high-power X-rays have revealed a potential drug target in H. pylori, the ulcer-causing bacteria that infect half the world's population.
n 1982, Australian scientists extracted bacteria from a person's stomach, grew them in a petri dish and identified them as the cause of ulcers and g... Read More
Following up on an ancient Russian way of keeping milk from going sour -- by putting a frog in the bucket of milk -- scientists have identified a wealth of new antibiotic substances in the skin of the Russian Brown frog. The study appears in ACS' Journal of Proteome Research.

New tests that promise to speed up diagnosis of food poisoning pose an unexpected problem: They could make it more difficult to identify dangerous outbreaks like the one that sickened people who ate a variety of Trader Joe's peanut butter this fall.
The problem: These new tests can't detect c... Read More
The millions of bats succumbing to a deadly fungal infection across the country will leave massive ecological holes in their wake--prime predators of insects are disappearing, for one, and cave flora and fauna that depend on bats could be in danger of collapsing. But research on the animals’ imm... Read More
In a new essay, National Institute of Allergy and Infectious Diseases director Anthony S. Fauci, M.D., and David Morens, M.D., reflect on what has been learned about emerging infectious diseases (EIDs) in the two decades since a major report from the U.S. Institute of Medicine rekindled interest...

As the prevalence of antibiotic-resistant infections continue to rise around the world, a hospital in Canada detected the presence of New Delhi Metallo-ß-lactamase-1-Producing Klebsiella pneumoniae (NDM1-Kp), a multidrug resistant bacteria that is resistant to carbapenems, one of the last lines ...

I've spent most of the week with the flu. I'd heard flu season was starting early this year, but I wasn't prepared for it to be this early, in part because predictions for flu outbreaks are still not that precise—especially in germy places like here in New York City.
But a new approach, borro... Read More
Although both cooperation and conflict are decisive forces in evolution, some of the most successful microbial strategies for survival have arisen from cooperation. At times, two or more microorganisms can even come together to breathe as one. Breathing, or respiration, accomplishes a most chal... Read More
The SARS epidemic of 2002-2003 was short-lived, but the new human coronavirus that is alarming public health authorities can infect cells from humans and bats alike, a fact that could make the animals a continuing source of infection, according to a study to be published in mBio today. The new c... Read More
