Researchers examined samples from the brains of patients with and without dementia and found lipopolysaccharide, a component of Porphyromonas gingivalis, an oral bacterium, in four out of 10 Alzheimer’s disease brain samples.
“This clearly shows that there is an association between oral bacte... Read More
Karen Schwarzberg and Mike Gurney, students in the Spring 2010 graduate course in Integrative Microbiology at the University of California at San Diego/San Diego State University Joint Doctoral Program, consider the implications of a paper recently published in Nature by Hehemann et al., that st...

Having an intimate relationship with photosynthetic microbes is a widespread strategy adopted by numerous unicellular and multicellular organisms. Some eschew a committed relationship, and simply nab the plastids, sequestering them inside vacuoles where they continue to photosynthesize for a whi... Read More
A post by Manuel Sánchez, host of the Spanish blog, Curiosidades de al Microbiologia, on an article entitled "Physical Virology " that appeared in Nature Phyisics, discuses the ideas and potential of a new discipline that studies viruses from a physical perspective.
"Viruses are able to spont... Read More

When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More
Here's a nice edu resource-related video about the biology of bacteria that the team over at SciVee.tv posted. It looks like it originally came from Maryland Public Television. This is probably good for many intro to microbiology type courses and high school level life science classes. Read More
A new post on the Bulletin for Atomic Scientists website reviews the U.S. Army's revised regulations for its biomedical labs. The updated requirements intends to clarify vague language in civilian biological agents guidelines. In addition, "the new regulations establish stricter controls on t... Read More

Antimicrobial resistance is not a new problem but one that is becoming more dangerous; urgent and consolidated efforts are needed to avoid regressing to the pre-antibiotic era.
For World Health Day 2011, WHO is introducing a six-point policy package to combat the spread of antimicrobial resis... Read More

In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More
When viruses come into contact with host cells, they trigger the cells to engulf them, or fuse themselves to the cell membrane so they can release their DNA into the cell.
Once inside a host cell, viruses take over its machinery to reproduce. Viruses override the host cell’s normal functioni... Read More
Here's a nice demonstration video by Dr. Conor O'Bryne from the Dept. of Microbiology at National University of Ireland, Galway, showing how to perform a serial dilution on a liquid food sample (in this case raw unpasteurised milk). The raw milk sample is diluted down to 1/1000 in a sterile dil... Read More
An outbreak of ten cases of poliomyelitis caused by circulating vaccine-derivied poliovirus type 2 (cVDPV2) is ongoing in Pakistan, centered in the Kila Abdulla/Pishin area of Baluchistan. The same virus strain has spread to the neighboring Kandahar province in Afghanistan, where two paralytic c... Read More
