Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is one of the resulting fungal growths: white with no spore formation, droplets can be seen as possible result of respiration. Read More
While isolating organisms growing in a water system a dark Fungal growth was noted. I love isolating fungi and staining them in a manner that produces contrast among the hyphae. This fungi is yet to be identified but through the lense of a microscope it looks comparable to a tree in the fall a... Read More

Neurons and biological shapes is a common theme in the works of the artist Maria Penil. Here she painted with yellow Nesterenkonia, orange Deinococcus and Sphingomonas isolated for their attractive colors as contaminants in the Berkmen lab. After growing the plates for 2 days at 30C, the artist ... Read More

Microorganisms reside everywhere, yet they are too small to be seen with the human eye. New York City (NYC) is a melting pot of cultures - both human and microbial - and every citizen has a personalized microbiome. Collectively, we shape NYC’s microbiome by our lifestyle choices, and this unseen... Read More
B. cereus was grown on urea agar for 6 days at 37 degrees C to induce spore formation.
The endospore stain was done using malachite green as the primary stain and safranin as counter the stain. Malachite green was applied to the smear and set over a steaming water bath for 10 min (stain was no... Read More
In 2011, the NIH Clinical Center had a cluster of infections of a pathogen that tops the CDC's list of urgent threats: antibiotic-resistant Klebsiella pneumoniae.
