It has been assumed that mothers pass on gut microbes to their infants during and just after delivery, a process called vertical transmission, but because of technical restraints, the evidence of this occurring has been limited. Previous cultivation-free studies have observed the same microbial ... Read More
In a new paper, researchers debunk the common myth that in the human microbiome, bacteria outnumber human cells 10-to-1. By examining the colon, the researchers estimate that the total number of bacteria in the human microbiome is 38 trillion (for the average 70-kg man). For comparison, the auth... Read More

The TWiVirions reveal bacteriophage genes that control eukaryotic reproduction, and the biochemical basis for increased Ebolavirus glycoprotein activity during the recent outbreak.

The hamlet of Resolute Bay is a tiny Arctic village in the Nunavut territory of Canada with a population that hovers at or below 300. Over hundreds of perhaps even thousands of years, the traditional Inuit diet in Resolute Bay and elsewhere has been dictated by the Arctic environment. The diet i... Read More
Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More
A major goal of viral oncotherapy – the use of viruses to destroy tumors – is to design viruses that kill tumor cells but not normal cells. Two adenoviruses provide perfect examples of how this specificity can be achieved.
Adenovirus CG0070, designed to treat bladder cancer, and adenovirus O... Read More
Last Fall, the great Dr. Margaret McFall-Ngai "virtually visited" my freshman writing class at the University of Puget Sound to discuss symbiosis and Microbial Supremacy with my new students. I had my students read some papers by Dr. McFall-Ngai (including the wonderful "Animals in a Microbial ... Read More
"Hivi and his team of viruses (Ebola, Pox,..etc) believe they can win the battle, but the Virologists (who are real famous professors) beat them. However, new viruses pop-up, it will be a long battle. This makes the story very interesting and ever so engaging."

In this blog post, I discuss making student designed artwork using bioluminescent bacteria as "paint." As student "buy in" is critical for any course, such fun "creative" approaches act synergistically to improve learning and outcomes. Feel free to vote on your top six images---the students ar...

How do chronic infections change over time? This is the broad question addressed in recent research published in the Journal of Virology. In their study, a team of scientists headed by Fabio Luciani investigated a hepatitis B virus infection over a course of 15 years.
Hepatitis B virus (HBV) ... Read More
After the governors of New York and New Jersey decided that health workers who have returned from the Ebola virus outbreak in West Africa should be subject to a 21-day quarantine, two Nobel laureates entered the fray. Bruce Beutler feels that the quarantine is the right thing to do, while Peter ... Read More
As far as I know, mosquitoes do not eat sushi. But mosquito cells have proteins with sushi repeat domains, and these proteins protect the brain from lethal virus infections. Read More
Microbial infection is implicated in an ever-growing number of types of cancer. Adding to the already long list of microbial-associated cancers, an increasing body of evidence suggests breast cancer may also be associated with a specific microbial milieu. A report in Applied and Environmental Mi... Read More
I hope we have all had an opportunity over the past holiday weekend to give thanks for what we have—it is important to step back and reflect from time to time on the many benefits and advantages we have. It can help us realize what we have achieved, and the multitude of people and resources that... Read More
BDP FL maleimide
BDP FL maleimide is a bright and photostable thiol-reactive dye for protein labeling, an ideal replacement for fluorescein for microscopy. BDP FL is a borondipyrromethene dye which has absorption and fluorescence spectra similar... Read More
Infection control is a vital part of maintaining a safe healthcare facility, and the use of biocides and disinfectants to eliminate potential pathogens is an important part of infection control strategy. Pathogens can spread among patients via transfer to surfaces like doors, floors, and counter... Read More
One of the most important aspects of a new laboratory protocol is its reproducibility (as previously discussed on ASM’s Microbial Sciences blog). A protocol must produce the same results when performed by different scientists at different labs, and this is especially important when considering n... Read More
The ASM Biothreats conference covers preparation for, handling during, and analysis of infectious disease outbreaks, and includes session on research, response, and policies on biological threats and emerging infectious diseases. Most sessions cover broad topics such as emergency preparedness, v... Read More
Given the extent of the Ebola virus outbreak in West Africa, transport of an infected individual to the US was bound to happen. The case is an adult who had contact with an Ebola virus-infected woman in Liberia, then traveled to Dallas. He had no symptoms before arriving in the US and therefore ... Read More
