Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, Johns Hopkins researchers have confirmed a key way in which Zika virus causes microcephaly and other damage in fetal brains: by infecting specialized stem cells that build its...

Given the complexity of host-microbiota symbioses, scientists and philosophers are asking questions at new biological levels of hierarchical organization—what is a holobiont and hologenome? When should this vocabulary be applied? Are these concepts a null hypothesis for host-microbe systems or l... Read More
Viruses attack cells and commandeer their machinery in a complex and carefully orchestrated invasion. Scientists have longed probed this process for insights into biology and disease, but essential details still remain out of reach.
A new approach, developed by a team of researchers led ... Read More
A growing body of evidence indicates that the trillions of microbes that live on and inside our bodies affect our health. Collectively, these resident microbes form our microbiome.
In a new paper appearing in the journal Cell Host & Microbe, researchers at the University of Washington report ... Read More
No one knows for sure how they got there. But the discovery that bacteria that normally live in the gut can be detected in the lungs of critically ill people and animals could mean a lot for intensive care patients.
Today, scientists are reporting that they found gut bacteria in the deepest r... Read More
The Microbiome is enjoying some much deserved attention as people are starting to realize that we are not alone in our body.....and its a good thing! Culture was done using a large TSA plate, Serratia marcescens (red), Staphylococcus epidermidis (white, arms and legs), and an unknown environmen... Read More
This episode: Bacteria in mosquito cells can block transmission of Zika virus!
(8.1 MB, 8.9 minutes)
Washington, DC – August 1, 2016 – Plasmids are pieces of independent DNA that often carry multiple antibiotic resistance genes. Plasmids can jump from one bacterium to another, spreading that resistance. A team of French investigators now shows that bacteria that acquire plasmids containing res... Read More
The TWiV academia discuss induction of diarrhea by the capsid protein of an astrovirus, and association of a fungal RNA virus with white-nose syndrome of North American bats.
How is it that we are we able to devote so little of our personal time and energy to producing or acquiring the healthy, safe food that we consume multiple times every day? A large part of the reason we seldom worry about agricultural output is that most of us benefit enormously from modernized,... Read More
Evidence suggests that microbes existed on Earth as far back as 3.7 billion years ago, a billion years after the planet formed. Animal remains, however, don't appear in the fossil record until 600 million years ago during the Ediacaran period, though there are indirect signs that animal life may... Read More
New Haven, Conn.--A novel combination therapy cures an emerging infectious disease, babesiosis, which is transmitted by the same ticks that transmit the agents of Lyme disease, said Yale researchers. This "radical" therapy not only clears the infection but also prevents the recurrence that often... Read More
From archaeal viruses to zoonotic diseases, the breadth of microbiology stories covered on mBiosphere in 2016 was impressive. Here are some of the best posts on mBiosphere from throughout this past year:
A new microscopic technique is enabling scientists to observe the antibiotic daptomycine live in action. This marks an exciting first, because even though doctors have been prescribing this antibiotic for over a decade, its precise mechanisms have remained unclear.
First, the scientists tagg... Read More
Is the United States at risk for a large-scale outbreak of Zika or other mosquito-borne disease? While climate conditions in the U.S. are increasingly favorable to mosquitos, socioeconomic factors such as access to clean water and air conditioning make large-scale outbreaks unlikely, according t...

That is the amount of money the U.S. spent over a 10-year period from 2004 through 2013 promoting abstinence before marriage as a way of preventing HIV in 14 countries in sub-Saharan Africa. Unfortunately, according to the most comprehensive independent study conducted to date of the effort, the... Read More
With Chagas disease becoming more prevalent in the United States, a diagnostic to quickly and easily detect infection is needed. Today, IDRI (Infectious Disease Research Institute) announces that a fusion antigen it developed and patented is being used as part of a Chagas disease diagnostic test... Read More
Since 2013, the mosquito-borne Chikungunya virus has spread rapidly through South America and the Caribbean, and is now threatening Southern Europe and the southern US. It causes flu-like symptoms with fever and joint pains, which in some cases can last for months with occasional fatalities. No ... Read More
Today was the last day of my microbiology course at the University of Puget Sound. So I thought it appropriate for students to tell me the single "coolest" thing they learned in my course. Read More
It’s difficult to make predictions, especially about the future, and even more so when they involve the reactions of living cells — huge numbers of genes, proteins and enzymes, embedded in complex pathways and feedback loops. Yet researchers at the University of California, Davis, Genome Center ... Read More
