This picture depicts that microbes too can add colours to life. As the beginning of a New Year adds colour to life. This agar art shows how microbes like serratia marcescens, Pseudomonas aeruginosa, Staphylococcus Citrus add to happiness of new year and too add colours to life. Read More
On a lavender background, this illustration provides a 3D graphical representation of a generic influenza virion’s ultrastructure, and is not specific to a seasonal, avian or 2009 H1N1 virus.
There are three types of influenza viruses: A, B and C. Human influenza A and B viruses cause season... 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
Scientists have engineered yeast cells that can “talk” to one another using a versatile plant hormone called auxin.
Typically, these simple fungal cells (Saccharomyces cerevisiae) usually do their jobs—making bread rise or converting sugar into alcohol—without having to communicate or work to... Read More
Previously, biologists at Emory University and the University of Michigan discovered that butterflies use plant toxins as a drug to cure their offspring of parasitic infections. Now they've dug a little deeper and found that the fungi associated with the roots of milkweed plants change both the ... Read More

The foreground shows the density map (gold) from a cryoelectron micrographic reconstruction of malabaricus grouper nervous necrosis virus, a fish nodavirus. The background shows the fitting of a two-domain model consisting of a protruding domain and a β-sandwich domain into the reconstruction de... Read More
A deadly parasite that causes Chagas disease is widespread in a common Texas insect, according to a new study by University of Texas at El Paso (UTEP) researchers. The finding suggests that the risk of Texans contracting the disease may be higher than previously thought. Read More

Compared with routine medical care, probiotics administered to critically ill patients in intensive care units showed no benefit in preventing the colonization of drug-resistant microbes in the intestinal tract, according to new research at Washington University School of Medicine in St. Louis.

2009 Nikon Small World Competition award 10th place: Leave it to the diminutive diatoms to bring out algae's best side. Only 10 times larger than life, this image was captured via dark-field by Arlene Wechezak in Anacortes, Wash. Such diatoms have been proposed as a key biofuel source of the fut... Read More
Tired of the portraits, landscapes and abstract art that peppers the walls of most art museums? According to Dutch photographer Wim von Egmond, there’s one art subject that has been ignored for centuries and finally deserves its due: microscopic organisms.
The production of Metallo-β-lactamase is one of the resistance mechanisms of Pseudomonas aeruginosa. Metallo-β- lactamases are members of Group B in the molecular classification of Ambler and are Clavulanic acid resistant enzymes which require divalent cations of zinc as co-factors for enzymat...
