E. coli K-12, a non-pathogen for most part, is a sorbitol fermenter and appears as pink to red colored colonies whereas E. coli O157:H7 colonies are not colored, on the differential BBL™ MacConkey II agar with sorbitol media plates. These two strains were used to paint the abstract sun, whose wa... Read More

Origene. In this picture, nucleic acids are showing the origin, the very beginning, the masterpiece where evolution take place in the microbial world! Some of the genetics "branch" DNA or RNA is revealing most of the microbial diversity that sustains our biosphere. It is amazing how the genetic... Read More
Companies selling ‘probiotic’ foods have long claimed that cultivating the right gut bacteria can benefit mental well-being, but neuroscientists have generally been sceptical. Now there is hard evidence linking conditions such as autism and depression to the gut’s microbial residents, known as t... Read More
The skin microbiome is considered our first line of defense against pathogens. Across our bodies, we are covered with a diverse assemblage of bacteria. Panelists will discuss how the skin can be a harsh environment for beneficial bacteria to live on and how these suboptimal con... Read More
You must have heard it said that no one is indispensable to an institution. Maybe so, but such truths come in degrees. Every so often someone comes along who makes a genuine difference in how an organization functions. I turn here to Michael Goldberg, who thirty years ago began a most distinguis... Read More
A novel method of altering a protein in milk to bind with an antiretroviral drug promises to greatly improve treatment for infants and young children suffering from HIV/AIDS, according to a researcher in Penn State's College of Agricultural Sciences.
That's critical because an estimated 3.4 m... Read More
Unknown environmental contaminant on blood agar plate streaked with Enterococcus faecalis. Plated was incubated at 37 degrees C for 24 hrs then held at room temperature. Contaminant was not seen until plate was held at room temp for several weeks. The organism was red, mucoid, and had raised... Read More
In a recent study, scientists at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), demonstrate for the first time that ocean acidification could have negative impacts on diatoms in the Southern Ocean. In laboratory tests they were able to observe that under chan... Read More
Saint Louis University research findings published in the December issue of Antimicrobial Agents and Chemotherapy report a family of molecules known as nucleotidyltransferase superfamily (NTS) enzyme inhibitors are promising candidates for new herpes virus treatments.
The findings could lead ... Read More

Intracellular pathogens face many daunting problems, among them how to obtain enough energy and nutrients for active growth while, preferably, keeping the host cell alive for as long as possible. This issue is especially acute for pathogens that grow at a fast rate and reach large numbers. When ... Read More
When you’re the size of a human, you worry about lions and tigers and bears. But if you’re a bacterium, a tiny nematode worm, just a millimetre long, can be a vicious predator. Nematodes are among the most common animals on the planet, and many of them hunt bacteria in soil and water. The microb... Read More
This picture shows a funny kitten named Salmonelly. The black silhouette of that kitten was made by using the bacterium Salmonella enteric serovar Typhi(ATCC® 6539™), the causative agent of Typhoid fever, a human bloodstream infection that is common in the developing world. The pink hair bow dec... Read More
This is my video to participate to the ASM Global Video Challenge. It explains that bacteriophages, which are viruses specifically targeting bacteria, are not dangerous for humans. The myth that all viruses are dangerous for human is broken! This myth is often encountered in the growing field of... Read More
Where does HIV hide? Antiretroviral drugs can usually control the virus, but can’t completely eliminate it. So any strategy to eradicate HIV from the body has to take into account not only the main group of immune cells the virus targets, called CD4 or helper T cells, but other infected cells as...

Multiple governments and non-governmental organizations have called on health-care personnel the world over to help control West Africa's Ebola outbreak; these include Médecins Sans Frontières (MSF), the World Health Organization (WHO) and United Nations children's charity UNICEF. But the demand... Read More
If you've ever enjoyed the scent of a pine forest or sniffed a freshly cut basil leaf, then you're familiar with terpenes. The compounds are responsible for the essential oils of plants and the resins of trees. Since the discovery of terpenes more than 150 years ago, scientists have isolated som... Read More
UNSW Australia researchers have shown that changing just a single letter of the DNA of human red blood cells in the laboratory increases their production of oxygen-carrying haemoglobin - a world-first advance that could lead to a cure for sickle cell anaemia and other blood disorders. Read More
