This episode: Engineered bacteria can be made to produce many different useful kinds of biofilm!
(10.5 MB, 11.5 minutes)
Bacteria can elaborate complex patterns of development that are dictated by temporally ordered patterns of gene expression, typically under the control of a master regulatory pathway. For some processes, such as biofilm development, regulators that initiate the process have been identified but s... Read More
Dean Dawson, Associate Member of the Cell Cycle and Cancer Biology Research Program at the Oklahoma Medical Research Foundation, has authored a post on Small Things Considered which explores Candida's chromosomal instability and unorthodox reproduction process.

Are there environments where there are abundant bacteria and no phages? Sounds like one of our Talmudic Questions, but this one has a specific answer, and that answer is Yes. That environment was found within a cystic fibrosis (CF) lung.
This story comes from a pair of papers recently publish... Read More
Got your attention, eh? This page discusses why so many people believe that antibiotics kill viruses, and what you can do about that myth. Actually, it's not even a myth ... antibiotics DO work against viruses. The problem is that the word "antibiotics" is redefined by some to be a synonym of... Read More
Vincent and Glenn meet up with Ann and talk about her long and productive career in virology, from biochemistry to bacteriophage lambda to retroviruses.
In this blog post, I describe a simple "colony transformation" experiment I have done with my freshman students, illustrating transformation, antibiotic resistance, and GFP. The visual aspects help drive home the points effectivel. Read More
Most of you are probably back to work after the ASM conference in San Diego. It was a great conference with a lot of exciting talks and posters and we hope you enjoyed our beautiful city.
MO BIO Labs presented four posters at ASM and the PDFs are now available online for viewing. These were t... Read More

The World Health Organization’s campaign to eradicate poliomyelitis made impressive inroads in 2012: only 212 cases were reported, compared with 620 the previous year; moreover, India remained polio-free. The dark side of this story is that as wild polio is eliminated, vaccine-associated poliomy... Read More
Now that we have experienced several months of the H1N1 pandemic, what have we learned about how it was handled? Watch Dr. Nicole Lurie (U.S. Department of Health and Human Services) and Dr. Kathryn Edwards (Vanderbilt University), discuss the public health responses to H1N1. Participants compar... Read More
While reading my back issues of Applied and Environmental Microbiology (AEM), I came across an interesting paper that detailed an in-depth study on the effectiveness of hand cleaners to remove Norwalk virus (NV) from intentionally contaminated hands.
Yes that’s right – intentionally contamina... Read More
Dear TWIM hosts,
I enjoyed episode 76, "Genetic biopixels and a pathogenic sweet tooth". I really enjoyed hearing about the course that Dr. Schaechter teaches and in particular the work his students did in developing the biosensor. I would like to ... Read More
Robert A. Weisberg was a Scientist Emeritus at NCI until the time of his death on 1 September 2011. Previously he was Chief of Microbial Genetics at NICHHD, a position he retired from in 2008. He was a pioneer in the study of the bacteriophage lambda. His research lead to seminal contributions a... Read More
In this blog entry, I explore how students can use their creativity to learn microbiology in innovative and often artistic ways. It makes learning more personal! Read More
Earlier this month the European Molecular Biology Laboratory (EMBL) published the DNA sequence of the genome of HeLa cells, the cell line that is widely used for research in virology, cell biology, and many other areas. This cell line was produced from a tumor taken from Henrietta Lacks in 1951.... Read More
El podcast del Microbio Nº255 explains the use of the fungus Beauveria bassiana as bioinsecticide for the control of the red pa... Read More
Deans of public health schools in the United States have sent a letter to President Obama, in which they criticize the use of a vaccination campaign by the Central Intelligence Agency in Pakistan to hunt for Osama bin Laden. I wonder if he will reply. Read More
Poliovirus recently made the cover of Time magazine. Prompted by a reader question, I searched the Time archive to find out if there have been other virology-themed covers. I found fifteen in all, depicting poliovirus (3), herpesvirus (1), HIV/AIDS (4), influenza (5), and SARS coronavirus (2) (I... Read More
