Vaccinating one-year-olds against chickenpox could temporarily nearly double the incidence of shingles in the wider population, but in younger adults than previously thought. Read More
Colorized electron micrograph of red blood cell infected with malaria parasites (blue). The small bumps on the infected cell show how the parasite remodels its host cell. Uninfected cells (red) have smoother surfaces.

CHAMPAIGN, Ill. -- A new analysis supports the hypothesis that viruses are living entities that share a long evolutionary history with cells, researchers report. The study offers the first reliable method for tracing viral evolution back to a time when neither viruses nor cells existed in the fo... Read More
Pseudomonas aeruginosa is one of the most notorious organisms that have brought the therapeutic dilemmas to clinicians as well as challenge to microbiologist throughout the world. It carries gene of intrinsic resistance (AmpC cephalosporinase, the OprD outer membrane porin, and the multidrug ef... Read More

Our sensitivity instruments rarely ever go down, but when they do our lab uses Kirby-Bauer testing to perform antimicrobial susceptibility testing in our laboratory. This testing involves placing antibiotic-infused discs on a standardized inoculum of bacteria spread in a lawn onto a Mueller Hint... Read More
Pictured here are blue colonies of Methicillin-resistant Staphylococcus aureus (MRSA) growing on Remel Spectra MRSA medium. Spectra media contains a chromogen that yields a blue color as a result of phosphatase activity. The phosphatase enzyme is present in many staphylococci, including Staphylo... Read More
This confocal micrograph, taken as part of a synthetic biology project, shows Bacillus subtilis, a Gram-positive, rod-shaped bacterium that is commonly found in soil. Distinct lineages of bacteria expressing different fluorescent proteins were initially mixed randomly on a petri dish. As the bac... Read More
Bacillus cereus, a food-borne pathogen, is capable to form biofilms. Biofilms are microbial communities that are controlled by a biological mechanism called quorum sensing. In this image, the B. cereus biofilm was viewed under microscope using LPO and grown in microtiter plate well for 48 hrs of... Read More
Philadelphia artist Kate Kaman (www.katekaman.com) has designed a dynamic larger-than-life sculptural depiction of the most plentiful and ancient microscopic life forms -- bacteria. Suspended throughout an area measuring approximately 130 feet long, 27 feet wide and 41 feet tall, “The Unseen Wor... Read More
Shock! Horror! Some treasured molecular paleoenvironmental tools of organic biogeochemists—namely the alkenones, an esoteric group of long-chained compounds made by aquatic microalgae—are being put forward by O’Neil et al.1 as candidates for conversion to jet fuel on an industrial scale! (See... Read More
A colorized electron microscope image captures delicate chains of streptococcus in a laboratory sample. Though some strep infections can be deadly, many strains are harmless—among the thousands of benign beings that make their home in our bodies.
