Scientists at Karolinska Institutet in Sweden have presented a new principle for fighting bacterial infections, in other words, a new type of antibiotic, in the FASEB Journal. The new antibiotic mechanism is based on selectively blocking the thioredoxin system in the cells, which is crucial to t... Read More
Researchers have found that the organism that causes deadly white-nose syndrome persists in caves long after it has killed the bats in those caves.
A study just published in Applied and Environmental Microbiology shows that the fungus can survive in soil for months, even years, after the bats... Read More
Tomorrow morning, the US Food and Drug Administration will consider whether to accept reauthorization of legislation that allows us to know a few details about how many antibiotics are sold each year for agricultural use.
The agency probably will accept the reauthorization, and you would thin... Read More

A new model of the how the protein coat (capsid) of viruses assembles, published in BioMed Central's open access journal BMC Biophysics, shows that the construction of intermediate structures prior to final capsid production (hierarchical assembly) can be more efficient than constructing the cap...

The Ebola virus uses a protein decoy to undermine and evade the immune response of its infected host, new research shows.
Ebola virus is the causative agent of Ebola Hemorrhagic Fever (EHF), a disease with up to 90 percent mortality. While human outbreaks of Ebola hemorrhagic fever have been ... Read More
Multidrug-resistant bacteria remain a major concern for hospitals and nursing homes worldwide. Propagation of bacterial resistance is alarming and makes the search for new antimicrobials increasingly urgent. Scientists at the Max Planck Institute for Biophysical Chemistry in Göttingen have now i... Read More
El podcast del microbio Nº 361 summarize the article writen by Marks LR, Reddinger RM and Hakansson AP and published in mBio about the high levels of genetic recombination in Streptococcus pneumoniae ... Read More
A disease impacting bat colonies in North America has yet to surface in Colorado. However, a new study is giving hope to local wildlife biologists on the look-out for potential outbreaks.
Bats with the white-nose syndrome are prone to immune reconstitution inflammatory syndrome (IRIS), a viru... Read More
A new pacemaker has been built inside a heart by converting beating muscle into cells which can organise the organ's rhythm, US researchers report.
The heartbeat is controlled by electrical signals and if these go awry the consequences can be fatal.
Scientists injected a genetically-modifi... Read More
I hope you never have this experience: A loved one is hospitalized. Her doctors tell you her infection is resistant to antibiotics. She dies. More than 60,000 American families go through that experience each year -- and the number is almost certain to rise.
Multidrug-resistant organisms are ... 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
New research from Lund University casts new light on the interaction between the immune system and streptococcus bacteria, which cause both mild tonsillitis and serious infections such as sepsis and necrotising fasciitis. The way in which antibodies attach to the bacteria is linked to how seriou... Read More
A coronavirus—genetically related to the SARS virus—that caused two infections and sparked the World Health Organization to issue an alert in September may be able to jump from a variety of bats and pigs to humans, and back again, according to a study published last month (November 20) in mBio. ...

In a study published today in the open access journal PLOS Pathogens, researchers at Emory University have discovered a potentially important mechanism by which the Ebola virus alters and evades the immune response of its infected host.
Ebola virus is the causative agent of Ebola Hemorrhagic ... Read More
There’s lots of news to catch up with regarding the new coronavirus that emerged last summer in the Middle East and has been causing concern to international health authorities all autumn: additional cases, additional deaths, and new lab evidence that is more than a little concerning.
First... Read More
Powerful X-rays have revealed a potential way to attack Helicobacter pylori, a stomach bacteria harbored by at least half the world’s population.
In 1982, Australian scientists extracted bacteria from a person’s stomach, grew them in a petri dish, and identified them as the cause of ulcers an... Read More
Researchers from Radboud University Nijmegen and B-WARE Research Centre have discovered new methane-consuming bacteria in the soil beneath the Brunssummerheide peatland reserve in Limburg, the Netherlands. Although the bacteria may be the result of environmental pollution, they are now consuming... Read More
