This is included in my recent blog post (http://microbesrule.blogspot.com/2015/12/happy-luxmas-2015.html), but here it is by itself. Photobacterium leignothi "stars" on Petri plates hung on my tree, and a 5 second exposure makes for a nondenominational "Luxmas Tree." Happy Microbial Holidays! Read More
In this blogpost, I celebrate the microbiological season with some microbial merriment: ice nucleation bacteria, drawing with reporter gene bacteria, and painting with bioluminescent microbes. Every day is Luxmas to me! Read More
Unknown organism seem after washing hands on a hand print grown on TSA. Larger organism (possible Bacillus spp) is circular, edges not smooth, mucoid with rhizoid like growth towards the edges. Second smaller organism is yellow, mucoid, and has something erupting from the center. Read More

I have long believed that there are many ways for students to learn. In several of my classes, I encourage students to use "creative" approaches to explore course concepts. In the Fall of 2015, here is what my micronauts in my Microbiology course at the University of Puget Sound came up with..... Read More
Unknown organism, possible Bacillus spp, washed hand print done on a TSA plate. Organism was the size of a dime, muciod/ rhizoid in the center and mat/smooth at the outer edges. Read More
A urine specimen was collected by catheterized patient and sent to our Mycology laboratory for fungi research.
Small and translucid colony have grown on Sabouraud Agar (50mg chloramphenicol) culture after a week.
Microscopic analysis was performed and unusually shaped, swollen and large organ... Read More
Unknown organism, presumable yeast, seen on Bile Esculin Agar (BEA) after several months at refrigerated temperatures. Organism was mucoid.circular, and a light brown in color. The brown coloration around the colony indicates the organism can to convert the esculin into 6,7-dihydroxy-couarin p... Read More

Bacterial hand print done last week with a group of 4th graders (~30 plates done). This same thing was done 4 months ago with another group of 4th graders when the weather was warm and dry. A different hand "flora" can be seen between the two seasons. Notably the Bacillus species is different... Read More
Unknown fungal contaminant seen on Lipid agar after several months at refrigerated temperatures. Image taken using transmitted light to highlight the concentric rings of the colony. COlor was a dark brownish green. Read More

This is one of the most popular festivals in the Country. There are several reasons for this. Ganpati is after all a popular God. His blessings are invoked at most religious ceremonies as He is the one who can remove all obstacles to success. He is the giver of fortune and can help to avoid natu... Read More
Bacillus spp seen on the finger tip of a hand print grown on MH agar at 37 degree's C. Colony was the size of a dime with rhizoid branching growth. Read More
Unknown organism seen on a hand print done on MH agar incubated for 24 hrs at 37 degree's C. The edges of the colony were dry and mat but the center was mucoid/liquid. When the plate was tilted the liquid center of the colony look as if it would run or drip. A gram stain was done and G+ rods... Read More
It has been estimated that if every nutritional measure known to be helpful were applied to every child in the world, global malnutrition would be decreased by only a third. New research from the University of Virginia School of Medicine, the University of Vermont and the International Centre fo... Read More
