Unknown organism seen on the tip of a finger imprint done on MH. The colony, possible bacillus, was dry/mat throughout the colony. There were 3 pouches of liquid that can be seen in the colony. When the plate was tilted the liquid portion moved but did not break free from the membrane surroun... Read More

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
Beautiful bacteria. Chromobacterium violaceum, S. aureus, and S. epidermidis 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
The bearer of the Plague....Rat Flea obtained from the rattus rattus (rat) habouring the Yersinia Pestis (plague bacilli) which causes the dreaded Plague or the "Black death" that single handedly wiped out a quarter of the human population thru the middle ages. Thru hard work and science we have... Read More
"Two types of bacteria found in the soil have enabled scientists to get the dirt on how resistance to antibiotics develops along with a separate survival strategy.The study identifies an atypical antibiotic molecule and the way in which the resistance to that molecule arises, including the ident...

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
