Introduction and uses of culture media for growing pathogenic bacteria and fungi
In the early 1960s developments in agricultural production, sponsored by international funding agencies, led to what came to be called the Green Revolution. Unfortunately, this great leap forward in food production relies highly on the use of pesticides and artificial chemical fertilizers. The ... Read More
The human microbiome consists of thousands of viral and microbial species which inhabit the human body and have co-evolved with us to protect against pathogens, regulate organ function and supply nutrients and other factors essential for health. When these members fall out of balance, it can le... Read More
While the pathogen Chlamydia pneumoniae has been linked to asthma in the past, new research finds over two-thirds of people with severe asthma test positive for Chlamydia-specific antibodies, suggesting this antigen could be a good biomarker for detecting those at risk for asthma. Additional re... Read More
A number of variables can cause signficant changes in the human microbiome early in life including birth method and antibiotic exposure. Understanding these shifts is important because new research suggests that shifts in the microbiome of infants could make them more prone to gain weight as adu... Read More
Researchers are working on developing microbial fuel cells (MFC) that can generate electricity while accomplishing wastewater treatment. Read More
Using a microbial fuel cell to produce electricity and clean water. Read More
The health of humans, animals, and the environment are inextricably interconnected. Disruption of the environment often creates new niches for the evolution of infectious diseases, and provides opportunities for the transmission of pathogens to animals or humans. The majority of infectious disea... Read More
Traditionally, colonization of a host has been described in terms of a microbial community that does not affect the host, but recent research (such as the Human Microbiome Project) suggests that colonizing microbes are having an effect not only on the host, but on each other. Participants discu... Read More
Large concentrations bacteria identified in the nuclei of hailstones suggest that airborne microorganisms may be responsibility for the formation of these weather events. Participants will discuss these findings as well as the implications they may have for understanding of the role microbes pl... Read More
Modernization in developing countries may be accompanied by a transition from epidemic infectious diseases to chronic and degenerative illnesses as predominant causes of morbidity and mortality. The hygiene hypothesis posits that reduced exposure to infectious agents in childhood as a result of ... Read More
Over a year after the largest oil spill in the Gulf of Mexico, scientists are still investigating the role microorganisms play in cleaning up the mess, both on land and at sea. Participants will discuss the latest research, what we have learned and what we still do not know.

This animation starts with the explanation of bacterial cell wall synthesis, the process targeted by ß-Lactams.
Structurally, most bacteria consist of a cell membrane surrounded by a cell wall and, for some bacteria, an additional outer layer. Internal to the cell membrane is the cytoplasm whi... Read More
The ability of bacteria to be genetically manipulated in a directed way has permitted the application of bacterial metabolism and gene expression to the creation of products useful in a wide variety of domains, including alternative energy generation, novel and manipulatable pathways for antibio...

Julian Davies, University of British Columbia, discusses the future of antibiotics in his Society for General Microbiology Prize Medal Lecture at the Society for General Microbiology 2012 Spring Conference in Dublin, Ireland. Read More
In as little as 100 generations, yeast selected to settle more quickly through a test tube evolved into multicellular, snowflake-like clusters, according to a paper published in Proceedings of the National Academy of Sciences. Over the course of the experiment, the clusters evolved to be larger,... Read More
For a holiday card, my wife and I made a Christmas Tree with bioluminescent ornaments. The video shows how the tree looks in natural light, and then by its own light. The bacterium is Photobacterium leiognathi, isolated by Ned Ruby and Eric Stabb in Hawai'i. This is another example of where mi... Read More
From the Open University, a neat video highlighting seven amazing things microbes do. Read More
Leaking septic systems or manure from adjacent rural properties are the two most common sources of fecal contamination of a well. The University of Wisconsin Water Resources Institute is funding a new research project to refine a methodology to determine the source of well water contamination.
