Imprint of a tennis shoe done on a large TSA plate, grown for 24 hrs at 37 degrees C, held at room temp for 48 hrs then stored in the refrigerator. Interesting mix of a variety of bacteria (Bacillus spp) and possible yeast.
Kodamaea ohmeri grown on SabDex Agar at 30 C. An emerging human pathogen that has been shown to cause fungemia, endocarditis, funguria, and peritonitis in immunocompromised patients. It is resistant to most of the antifungal drugs. Read More
Organisms that have the catalase enzyme can detoxify the cell of hydrogen peroxide by converting it to oxygen gas. Bubbles indicate oxygen gas production after the addition of hydrogen peroxide directly to colonies growing on the TSA plate.

Fungal contaminant seen on TSA after several months at refrigerated temperatures. Green spore formation can be seen with exudate droplets through out. Hyphal growth extended up the side of the dish and onto the lid. Read More
Contaminant (yeast?) found on TSA after several months in the refrigerator. The larger colony was circular, mat with concentric rings with a smaller more mucoid yellow growth just off center. Read More
Unknown contaminant (yeast?) on BEA agar after 1 month in the refrigerator. Looks like there was moisture on the plate as the colonies grew in a drip like pattern. Colonies were mucoid salmon red in color with yellow pin point circular growths growing in through out. The edges of the colonies... Read More
It will be a great pleasure for me and my group if you can post on your Facebook page attached photos of Petri dishes.
A New Years way of examination of antimicrobial activity: Inflict on a Petri dish, a microorganism in the shape of a New Years tree, and then add some antibiotics... Read More
Fungal contaminant, presumably air borne, on BEA media after 1 month in the refrigerator. Circular white hyphal growth with no spore formation, white hypahl growth slightly mounding in the center. Area around the single colony was back indicating esculin hydrolysis. Read More
This endophytic fungi was isolated from Musa sp., the spore production was induced with moist chamber and was observed in a light microscope. Read More
This fungi was isolated from a Bonsai tree (Premna sp.) This isolation is part of a undergraduate research project (student: Christopher Sambolin), from the Interamerican University of Puerto Rico, San Germán Campus. Read More
Happy bacteria couple drawn on TSA plate using a MRSA culture.
This picture illustrates how happy bacteria can become when people don't take all the antibiotic treatment correctly. Antibiotic resistance is a big problem nowadays. Read More
The spooky, crimson plate in the center was drawn using Staphylococcus aureus to write Happy Halloween and draw the ghost. The eyes and mouth of the ghost were drawn with Staphylococcus epidermidis. Since S. aureus ferments the sugar mannitol in the MSA plate, the red dissipated and a yellowis... Read More
