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...

Zika virus RNA has been detected in New World monkeys from the Northeast region of Brazil. This finding suggests that primates may serve as a reservoir host for the virus, as occurs in Africa. Read More
Host: Jeff Fox with special guest, Jon Telling.
Jon Telling of Bristol University in Bristol, United Kingdom talks with Jeff Fox about his findings suggesting that the grinding of glaciers over rocks can liberate hydrogen, which, in turn, drives the growth of methanogens within microb... Read More
“Stefano, you seem like a smart person. Can I ask you why you decided to take a job with a scientific society?” I had just helped myself to a slice of a very sharp Stilton cheese, after a wonderful dinner supported by wonderful wine. All of a sudden the Stilton seemed even sharper. The question ... Read More
Single-celled organisms called bacterioplankton spend their lives drifting in open ocean, visible to the naked eye only en masse. But don't be fooled by their slight size: These minuscule critters play a hefty role in the carbon cycle. Heterotrophic microbes, by some estimates, process half of t... Read More
It has been speculated that the development of neurological disease and fetal abnormalities after Zika virus infection may be due to the presence of antibodies against other flaviruses that enhance disease. In support of this hypothesis, it has been shown that antibodies to dengue virus enhance... Read More
Because of its simplicity and the rapid time-to-result turnaround, gram staining plays an important role in clinical microbiology. Learning the cell structure helps eliminate potential disease etiologies: learning an isolate is a gram-negative rod doesn’t tell you what the diagnosis is, but it h... Read More
