Transmission electron micrograph of novel coronavirus particles, colorized in yellow.
I have received many questions about whether immunizing with Reston virus could protect against infection with Ebola virus. Usually the question comes together with the statement ‘because Reston virus does not cause disease in humans’. I can think of two reasons why a Reston virus vaccine is not... Read More
Unknown airborne fungal isolated contaminant found on TSA. TSA plate was incubated for 2 months at 4 degrees C once fungal growth was seen. Concentric rings of color (pink, green and white) can be seen throughout the colony with smaller colonies seen around the white edges of the colony due to s... Read More

On the first day of Micro class instructors have students do an environmental swab. This sample was subcultured from a student who did the bottom of their shoe. The organism, possible Bacillus sp., was tough to scrap off the agar so subculture was done by taking a small chunk of agar containi... Read More

Different view of an unknown airborne environmental isolate on Bile Esculin Agar (BEA) exhibiting a single circular colony. White hyphal growth with no spore formation. Clear to brownish exudate can be seen throughout the colony. This sample grew at refrigerated temperatures for several months.... Read More
Bacteria has the virtue (and sometimes the vice) of being able to grow at incredible speeds—some strains can double in cell count in as little as four minutes. Fernan Federici, a postdoctoral student at the University of Cambridge, is pioneering the art of capturing the split-second process. And... Read More
