The Naval Research Laboratory (NRL) has developed the benthic microbial fuel cell (BMFC) as a persistent power supply for marine-deployed applications. The BMFC operates on the bottom of marine environments where it oxidizes organic matter residing in sediment with oxygen in overlying water. The... Read More
In this blog entry, I discuss how marine microbiology is fascinating to students, as well as the topic leading me (via social media) to other marine microbiologists. One of those marine microbiologists made me a "shrunken coffee cup" (shrunken due to being carried below a kilometer of depth on ... Read More
The risk of being infected with human immunodeficiency virus type 1 (HIV-1) is substantially enhanced in individuals with other sexually transmitted diseases. For example, infection with herpes simplex virus type 2 (HSV-2) increases the risk ratio of acquiring HIV from 2 to 4. Explanations for t... Read More

I have found that students become involved, energized, and enthusiastic when I give them opportunities to explore topics in my classes using their own creative approaches and interests. So this semester, in my Biology 111 course at the University of Puget Sound, I found that students explored f... Read More
Archaeans are among the earliest forms of life that appeared on Earth billions of years ago. It’s now generally believed that the archaea and bacteria developed separately from a common ancestor nearly 4 billion years ago. Millions of years later, the ancestors of today's eukaryotes split off... Read More
Nº130 and 131 of "El Podcast del Microbio" is dedicated to the New York Times article (Nov 5, 2010) about the search for... Read More
How many different viruses are there on planet Earth? Twenty years ago Stephen Morse suggested that there were about one million viruses of vertebrates (he arrived at this calculation by assuming ~20 different viruses in each of the 50,000 vertebrates on the planet). The results of a new study s... Read More

The Centers for Disease Control and Prevention has released early estimates of the effectiveness of this season’s influenza vaccine in preventing influenza infection. Estimated vaccine effectiveness is 62%. But even if you get infected after immunization, you are likely to have reduced illness, ... Read More
In this blog, I share some "first word that comes to mind" responses of my freshman biology class to the words "germ," "bacteria," "cell," and "DNA." The way that we perceive an idea or concept definitely impacts our relationship with it. Thus, finding out what students think, coming into our ... Read More
Here is an interesting paper regarding pathogenic islands of staphylococci. It is extremely interesting from an evolutionary standpoint, a pathogenic standpoint, and as a virus fan such as myself, a virological standpoint. It is kind of old so I am not sure if u covered it. It later was inclu... Read More
Viruses are obligate intracellular parasites, which means that they must enter a cell to reproduce. As virions are too large to diffuse passively across the plasma membrane, cellular pathways for uptake of extracellular materials provide entry routes. The first step in entry is adherence of viru...

This episode: Non-pathogenic Clostridium difficile strains can protect hamsters against their disease-causing bacterial siblings!
(7 MB, 7.5 minutes)
When hamsters were colonized with toxin-free strains of C. difficile, they were better able to resist infection b... Read More
