Target 2 forms of iron to control cystic fibrosis lung infection

The bacterium Pseudomonas aeruginosa needs iron to establish and maintain a biofilm in the lungs of cystic fibrosis patients, and therapies have been proposed to deprive the bacteria of this necessary element. However, these techniques may not work, according to a new study published in mBio®, t... Read More

Plankton may spread oyster herpes virus

Plankton may be spreading a herpes-like virus that has been devastating Pacific oyster farms across the world, newly published research has found.

Veterinary scientist Dr Richard Whittington, of the University of Sydney, and colleagues, report their findings on Pacific Oyster Mortality Syndro... Read More

Officials Warn Of Dangers Of Tick-Borne Powassan Virus

A Poughkeepsie high school senior died suddenly, after he was bitten by a tick and contracted a severe virus.

As CBS 2’s Jennifer McLogan reported, Joseph Elone’s family said doctors had been treating their son for a summer cold – until he collapsed on the front lawn.

Elone, 17, was actual... Read More

Bacterial toxins cause deadly heart disease

University of Iowa researchers have discovered what causes the lethal effects of staphylococcal infectiveendocarditis—aserious bacterial infection of heart valves that kills approximately 20,000 Americans each year.

According to the UI study, the culprits are superantigens—toxins produced in ... Read More

Bacteria and Fungi Together: A Biofuel Dream Team?

A group of researchers enlist fungi and E. coli to make the first biofuel of its kind. It is an obvious idea—in fact, it’s how nature disposes of trees after they die. Yet before researchers at the University of Michigan tried it, no one had paired bacterium with fungus to make cellulosic biofue... Read More

A Salmonella Warning for Vegetarians

Contaminated meat and poultry are the usual suspects in salmonella food poisoning, and increasingly the bacteria is cropping up in produce. Now scientists have traced a large outbreak of salmonella to an unusual source: tempeh, the popular meat substitute.

The outbreak sickened nearly 100 peo... Read More

Why our colons are happy homes for bacteria

Biologists have figured out how it’s possible for some beneficial gut bacteria to reside and thrive in the ever-changing gastrointestinal tract.

The human body is full of tiny microorganisms—hundreds to thousands of species of bacteria collectively called the microbiome—which are believed to ... Read More

Bacterial Predators Feast on “Superbugs”

Scientists are turning to predatory bacteria to defeat drug-resistant infections. Microbiologists led by Daniel Kadouri, now at Rutgers University, lately have focused on two such predators—Micavibrio aeruginosavorus, which latches onto a germ and sucks out its innards, and Bdellovibrio bacterio...

Cleaning up toxic waste: directed evolution vs. designed machines

Some heavy metals are required in trace amounts for the survival of living organisms, however at higher concentrations these metals can be incredibly toxic. In Europe, the elements of highest concern are arsenic, cadmium, cobalt, chromium, copper, mercury, manganese, nickel, lead, tin, and thall... Read More

BacterioFiles Micro Edition 131 - Stacking Sucker Symbionts

This episode: Some insects have bacterial symbionts with super-small genomes inside their cells, and some of these symbionts have their own internal bacterial symbionts!

UC Davis researchers discover molecular target for the bacterial infection brucellosis

UC Davis scientists have uncovered a potential drug target for the development of an effective therapy against the debilitating, chronic form of the bacterial disease brucellosis, which primarily afflicts people in Mediterranean and Middle Eastern countries.

Brucellosis, which affects about 5... Read More

Oddly Microbial: Programmed Cell Death

The lab was a crime scene; dead and dying cells were everywhere—but did they commit mass suicide or were they murdered? The burly young post doc who discovered the corpses sat in the corner sobbing softly, his PI by his side. She was trying in vain to comfort her most promising young scientist i... Read More

Marine nematodes have a microbiome too

By now you’re probably aware that your entire skin surface (and every orafice) is swarming with millions of microbes. The human microbiome is pretty sexy science these days, but we’re not the only species that hosts our own customized microbial communities.

A LOT of marine species have microb... Read More

Sharks are overrated, lets talk about their microbiome (blog post)

Yes, like humans (all other animals on Earth), sharks have a gut microbiome too. Everyone’s just been way too busy talking about all that Megalodon crap to think about this *real* and much cooler science.

There is a diverse and abundant gut microbiome associated with finfish, sharks, and blue... Read More

Real-Time Mass Spectrometry On Living Microbes

Microbes are tiny synthetic masters, producing molecules that have led to many important drugs. Chemists want new ways to sift through the compounds produced by microbes to find the next big drug lead. Now, scientists report a mass spectrometry technique that allows them to monitor molecules pro... Read More

Bollux Bacteria Biofilm Formation to Prevent Disease (podcast)

In labs, bacteria may swim freely. But out in the world, including our bodies, bacteria often exist packed together in dense communities called biofilms. And these configurations can help them cause illness. Finding clues about how such bacteria group together could therefore lead to better ther... Read More

Antibiotic Use in Chickens: Responsible for Hundreds of Human Deaths?

In the long back and forth between science and agriculture over the source of antibiotic resistance in humans — Due to antibiotic overuse on farms, or in human medicine? — one question has been stubbornly hard to answer. If antibiotic-resistant bacteria do arise on farms, do they leave the farm ... Read More

How a virus spreads from animals to humans

On June 24, 2012, a 60-year-old Saudi man died from severe pneumonia complicated by renal failure. He had arrived at a hospital in Jiddah 11 days earlier, and some of his symptoms were similar to those in severe cases of influenza or SARS, but this wasn't either of those diseases.

This was so... Read More
