One of the most dangerous places for an infection to occur is in the bloodstream. Septicemia, when microbes are present in the blood, not only allows bacteria access to other internal organs through the highway of our circulatory system, but also can cause a massive inflammatory response, leadin...

Several papers published in Genome Announcements recently describe the sequences of new Zika virus isolates. Scientists have known the genomic sequence of at least one Zika virus isolate since 2007, but continue to publish newly isolated strains. What is the importance of these additional sequen...

So another Earth Day has come and gone. How did you spend yours? If you spent the entire day asleep, you used about half a kilogram of oxygen. Since I assume that you are alive and kicking, you probably consumed more oxygen than that. If you went about your normal business during the day, you pr... Read More
Greg Caporaso was sifting through blog posts on microbe.net, which covers the microbiology of built environments, when a study idea sparked for him and colleagues Jeff Siegel, Scott Kelley and Rob Knight.
“It became clear to me that there was a lot of interesting work being done to understand... Read More

Breast milk provides an inexpensive, nutrient-filled source of food for babies. Because of this, the American Academy of Pediatrics and the WHO recommend new mothers to exclusively breast feed their babies for the first six months of life, and continue up to two years (supplemented with other fo...

Not long after the appearance of an outbreak of viral disease, first scientists, and then newswriters, blame it all on mutation of the virus. It happened during the Ebolavirus outbreak in West Africa, and now it’s happening with Zika virus.
The latest example is by parasitologist Peter Hotez,... Read More

Like us, bacteria have their own microbial attackers, in the form of bacteria-specific viruses called bacteriophage, or phage. These phage come in a variety of flavors but can be broadly categorized into virulent, which immediately begin to replicate and lyse (burst) the infected cell quickly, a... Read More
The TWiPtastic trio solves the case of the Surfer from Switzerland, and reveal how taste-chemosensory tuft cells in the gut regulate immune responses to parasites.

Pneumonia remains a serious worldwide problem, especially among the young, elderly, and immunocompromised. Over 900,000 children die each year due to the disease, and respiratory syncytial virus (RSV) is the most common viral cause (Streptococcus pneumoniae and Haemophilus influenzae type b bein...
