Vincent visits the Rocky Mountain Laboratories in Hamilton, Montana and speaks with Marshall, Sonja, and Byron about their work on tick-born flaviviruses, innate immunity, and prion diseases.
Bacillus cereus, a food-borne pathogen, is capable to form biofilms. Biofilms are microbial communities that are controlled by a biological mechanism called quorum sensing. In this image, the B. cereus biofilm was viewed under microscope using LPO and grown in microtiter plate well for 48 hrs of... Read More
A fortuitous collaboration at Rice University has led to the total synthesis of a recently discovered natural antibiotic.
The laboratory recreation of a fungus-derived antibiotic, viridicatumtoxin B, may someday help bolster the fight against bacteria that evolve resistance to treatments in h... Read More
Solid-head power toothbrushes retain less bacteria compared to hollow-head toothbrushes, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) School of Dentistry.
The results of the study are published in the August issue of the Journal of Dental Hyg... Read More
Scientists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world's naturally derived antibiotic medicines.
Their hope now would be to see whether it is possible to manipulate this switch to make nature's anti... Read More
Rabies is usually transmitted through the bite of an infected animal into muscle tissue of the new host. From there, the virus travels all the way to the brain where it multiplies and causes the usually fatal disease. A new article sheds light on how the virus hijacks the transport system in ner...

A person’s home is their castle, and they populate it with their own subjects: millions and millions of bacteria.
A study published tomorrow in Science provides a detailed analysis of the microbes that live in houses and apartments. The study was conducted by researchers from the U.S. Departm... Read More
Speedy analysis reveals mutations, insights into outbreak, along with clues to origin, spread.
Responding rapidly to the deadly outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, working with the Sierra Leone Ministry o... Read More
Recently identified cell-cycle controls are targets for new drugs that fight infections by shutting down division.
A cell is not a soap bubble that can simply pinch in two to reproduce. The ability to faithfully copy genetic material and distribute it equally to daughter cells is fundamental ... Read More
This Week in Virology, the podcast about viruses, celebrated its 300th episode on Tuesday, August 26, 2014 with a live recording at the Washington, DC headquarters of the American Society for Microbiology. This special episode features the TWiV hosts Vincent Racaniello, Dickson Despommier, Al... Read More
Children who repeatedly become infected with malaria often experience no clinical symptoms with these subsequent infections, and a team led by UC San Francisco researchers has discovered that this might be due at least in part to a depletion of specific types of immune cells.
Working in Ugand... Read More
Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria ac... Read More
Common gut bacteria prevent sensitization to allergens in a mouse model for peanut allergy, paving the way for probiotic therapies to treat food allergies.
The presence of Clostridia, a common class of gut bacteria, protects against food allergies, a new study in mice finds. By inducing immun... Read More
Last week two American aid workers who had contracted Ebola while working in west Africa were released from a U.S. hospital and pronounced “recovered.” They had been flown to Emory University Hospital in Atlanta from Liberia earlier this month to receive care in the hospital’s specialized infect...

As the tally of deaths from the worst known outbreak of the Ebola virus continued its seemingly inexorable rise, the World Health Organization said on Thursday that the epidemic was still accelerating and could afflict more than 20,000 people — almost seven times the current number of reported c...

I have the grating feeling that the subject of self-assembly of complex biological structures may not always amass the level of respect it deserves. I reckon that its importance is generally appreciated but, as topics go, it tends at times to be set aside. Yet, this is one of the most magnificen... Read More
