Unknown organism isolated from a swab taken off the bottom of a shoe. Students were asked to swab something in the classroom. One swab was done on the bottom of a shoe and incubated on a TSA plate for 48 hrs at 37 degree’s C. The organism was difficult to scrape so a small chunk of the organis... Read More
Trillions of bacteria populate the human gut - which makes them more common than any other cells in our body. The composition of this bacterial population is very variable and influenced by our diet. Diseases, but also antibiotic treatments can induce significant shifts in this equilibrium. If e... Read More
Scientific experiments with the herpesvirus such as the one that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of ...

Immune cells that hang around after parasitic skin infection help ward off secondary attack, according to a study in The Journal of Experimental Medicine. These skin squatters may prove to be the key to successful anti-parasite vaccines. Read More
Unknown yeast isolated on TSA from a swab taken from the bottom of a shoe incubated at 25 degrees C. Yellow, mucoid, round colonies were seen after 2 weeks. This isolate grew equally well at 37 degree C with a growth time of ~ 1 week. Read More
Washington, DC – August 14, 2015 - Tungsten is exceptionally rare in biological systems. Thus, it came as a huge surprise to Michael Adams, PhD., and his collaborators when they discovered it in what appeared to be a novel enzyme in the hot spring-inhabiting bacterium, Caldicellulosiruptor besci...

Pictured is a culture of Mycobacterium tuberculosis growing colonies in the distinctive "serpentine cord" form seen in many strains of M. tuberculosis. These cords are made up of chains of cells that make chains due to a cell wall factor of MTB.
The cell wall structure of Mycobacterium is a m... Read More
