Scientists at a local laboratory say a new piece of technology there can identify bacteria a day earlier than traditional methods.

"If it's a blood infection or meningitis, getting that identification as fast as we can can mean the difference between life and death," said Karen Calvert, a mic... Read More

Troublesome strains of Staphylococcus aureus are often troublesome because they carry genes for superantigens and multiple antibiotic resistance. But don’t blame the bacteria. These genes are hitchhikers that arrived by horizontal gene transfer, embedded within mobile pathogenicity islands known... Read More

Women suffering from recurring urinary tract infections may carry a particularly hearty strain of E. coli bacteria that flourishes in both the gut and the bladder, and can migrate back and forth despite repeated treatments, a small new study finds.

Doctors believe that urinary tract infection... Read More

Shanghai Daily has a web page set up that shows the geographic distribution of H7N9 infections and fatalities in China. There is also a news feed, information on symptoms and a photo gallery. Click "source" to view. Read More

Giving the flu vaccine to pregnant women may bring significant benefits to their babies even before birth, a new study has found.

Canadian researchers studied the records of 55,570 mothers of singletons, of whom 23,340 were vaccinated during pregnancy from November 2009 through April 2010. Co... Read More

Robert Koch is one of the key figures in early bacteriology, helping develop culture techniques (e.g. solid media), critical reasoning (e.g. Koch’s postulates), and disease etiology (e.g. cholera and tuberculosis). He also published the first photomicrographs of bacteria (Figure 1A) in his 1877 ... Read More

18th International Bioinformatics Workshop on Virus Evolution and Molecular Epidemiology
(VEME 2013)

VEME 2013 will be organized August 25th – August 30th, 2013 at the University of Florida in Gainesville, Florida, U.S.A.

The workshop will have the following modules:

• 'Phylogene... Read More

In 2001, Kashefi and collaborators published an article in Applied and Environmental Microbiology reporting the surprising finding that several iron-reducing microbes can use gold as an electron acceptor for their respiration. These microbial alchemists included both mesophilic and thermophilic ... Read More

Just in time for swimsuit season, federal researchers are touting a faster, more accurate water-quality test to keep beaches open and people healthy.

“Water quality can change significantly in 24 hours. This way we’re identifying threats to human health almost immediately,” said Meredith Neve... Read More

Using the same strategy that a common virus employs to evade the human immune system, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine have modified adult stem cells to increase their survival -- with the goal of giving the cells time to exert their natural...

Raw oysters, a delicacy for foodies and a purported hangover cure (it isn’t) aren’t always the safest thing to eat. Pathogens such as Vibrio vulnificus, norovirus and Hepatitis A sometimes lurk in oyster flesh. These little nasties can cause food poisoning and norovirus specifically has no treat... Read More

One widely-used tactic for defense against phage and other mobile genetic elements is to deploy a CRISPR-Cas system (click here and here) to recognize and chop them into pieces. Based on sequenced genomes, 60% of Bacteria and 90% of Archaea have the wherewithal to dispatch invaders this way. But... Read More

Bacteria may draw other bacteria to a site of infection by laying down trails of a “molecular glue” that lead free-swimming individuals to come together and organize into colonies.

In the study, researchers were looking at how a species of bacteria called Pseudomonas aeruginosa attach and mov... Read More

A top New York chef teams up with Harvard scientists to explore the role of bacteria in fermentation. He hopes to better understand and tweak the process to create new and unique flavors to entice the palate. Sharon Reich reports. Read More

The cellular interior is criss-crossed by protein-based cables known as microtubules, each formed from 13 'protofilaments' composed of the protein tubulin. Microtubules are also associated with a host of other specialized proteins that help coordinate the transport of molecular cargoes and link ... Read More

IF we’re to believe half a century of daytime TV commercials, housekeeping is war — a perpetual battle against the sneaky soldiers of nature. For decades, we’ve armed ourselves with cleaning products to slay bacteria, scrape away fungus and torture mites. As our household organisms move up the e... Read More

Back when the Time Lord and I were still engaged, we went shopping for wedding rings. He only had one criteria: he wanted his ring to be made of platinum or a similar material forged in a supernova. It’s not quite as exotic as it sounds: most heavy elements were formed in supernovae, via a proce... Read More

Face masks help prevent people from getting the flu. But how much protection do they provide?

You might think the answer to this question would be well established. It’s not.

In fact, there is considerable uncertainty over how well face masks guard against influenza when people use them ou... Read More
