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
Chlamydia psittaci. Infected baby hamster kidney cell cultures, direct FA stain Read More
Escherichia coli use long, whip-like structures called flagella to propel themselves. Motors in the cell's wall spin the flagella into bundles that rotate counter-clockwise, creating a twist that causes the bacterium to rotate clockwise, or towards the right when viewed from above.

Acid Fast stain done on a mix of Staphylococcus aureus and Mycobacterium smegmatis. Carbol fuchsin was applied to the smear and set over a steaming water bath for 10 min to help penetrate the mycolic acid in the cell wall, then rinsed with acid alcohol which washes the carbol fuchsin out of al...
