Evidence for the Biosynthesis of Bryostatins by the Bacterial Symbiont “Candidatus Endobugula sertula” of the BryozoanBugula neritina

I thought this area of bryostatin study might spark your interest. It has the potential to treat cancer and Alzheimer’s disease. Whether looking at the way the compound is formed in nature or the challenge of synthesizing the compound is fascinating.

Exams, Science Art, and Learning!

In this blog post, I describe how I encourage microbiology students to draw cartoons about basic concepts in the course. I find that this approach promotes ownership, better comprehension, and gives me better insight into what the students are "seeing" in my class. Read More

Global Warming Damages Symbiotic Organisms

Ten years ago, Takema Fukatsu, PhD, prime senior researcher and leader, National Institute of Advanced Industrial Science and Technology (AIST) in Japan, was invited to Kyoto University as a symposium speaker of a meeting organized by Kenji Fujisaki, PhD, a researcher in the University's Graduat...

Moleculo Facilitates Assembly and Binning from Soil

Soil microorganisms carry out key processes for life on our planet, including cycling of carbon and other nutrients and supporting growth of plants. However, there is poor molecular-level understanding of their functional roles in ecosystem stability and responses to environmental perturbations.... Read More

You Say Auto-phagy, I Say Au-toph-agy: Let's Call the Whole Thing Awfully Amazing

The Nobel Prize for Medicine this year went to Dr. Yoshinori Ohsumi of the Tokyo Institute for Technology for his work on autophagy, the process of digesting unneeded or damaged cellular components. This process plays a role in many central cellular activities, with applications ranging from gen... Read More

Advancing Phage Therapy

New research conducted at the University of Miami in Coral Gables, Florida and the National Cancer Institute, in Bethesda, Maryland demonstrate that a subset of bacteriophages, dubbed “superspreaders,” potentially play a major role in transmitting antimicrobial resistance. The research, describe... Read More

Seeking understanding of the bacterial sec system

How do bacterial proteins destined for export move from inside to outside the cell? As mBiosphere readers may know, there are a number of secretion systems that bacteria use to move materials from inside the cell to outside the cell. Some of these systems, such as the Sec secretion system, are c... Read More

Influenza Viruses by James McSharry, PhD

In this ASM Virtual Lecture Dr. James McSharry, Professor Emeritus, Albany Medical College, describes the structure of the influenza viruses, types of human influenza viruses and their replication in cells, licensed influenza drugs, current influenza vaccines, and the future of influenza vacci...

S. mutants mutation increases fluoride resistance


Microbes are excellent at adapting to stressful situations, which is part of the reason antibiotic resistance is a problem today. Constant exposure to antimicrobials such as triclosan have selected for resistant strains, rendering the compound ineffective. This is why the FDA recently banned t... Read More

History Lesson - The Day the US Senate Tried to Change the Name of Salmonella

In an attempt to preserve and defend the good name of the salmon fished in his state, Senator Warren Magnuson (D-WA), introduced in 1969 a bill in the US Senate pro­po­sing to change the name of Salmonella  to the more in­oc­cu­ous sounding Sanella. In some circles it may seem com­for­ting to th...

#microMOOCSEM2: Twitter as a tool to knock down walls and build bridges

The second edition of microMOOCSEM, the massive online open microbiology course by Twitter supported by the Spanish Society for Microbiology (SEM), will star on March 7. Twitter can be a weapon of mass destruction, but we are going to show again that this social network is an excellent tool for ... Read More

MetaPalette: a k-mer Painting Approach for Metagenomic Taxonomic Profiling and Quantification of Novel Strain Variation

Taxonomic profiling is a challenging first step when analyzing a metagenomic sample. This work presents a method that facilitates fine-scale characterization of the presence, abundance, and evolutionary relatedness of organisms present in a given sample but absent from the training database. We ... Read More

Global warming collapses symbiotic gut bacteria, killing host insects

A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study, reported online this week in the journal mBio®, illustrates another way globa... Read More
