OH MY GOD. Lady, you are truly a gift to us Microbiology students around the world. WHERE CAN I FIND MORE OF YOUR LECTURES? I WANT THEM.

[@sophiaherleyy7382]

...I’m half way thru my semester and you just explained everything in a 7 minute video that I’ve been trying to understand the past 2 months. My professor SUCKS! Tysm

[@colekena5018]

OMG This is the best video I have seen thus far on Gram Positive and Gram Negative staining. Thank you so much for thoroughly explaining this process.

[@AAA97391]

This is gold.... thank you!

[@kosgengster1991]

Perfect! Thank you! Succint and the illustrations helped a lot.

I want to point out that while yes, the crystal violet does eventually wash off from the Gram negative bacteria, it's the iodine that encapsulates the Gram positive first, so they don't get decolorized by the alcohol. That's when the last stain (the Safranin) would stain the Gram negatives. I understand this is an educational video, and I know some of it may have been a little rushed for the sake of getting the point across, but I believe that understanding the process of staining and how it actually works is much more beneficial to viewers than a simple, "it stays purple because that's just what Gram positives do."

My goodness lady! Before watching this video, I was completely oblivious to Gram-Staining, and how it works. I'm so glad God used you to put this video up, because he KNEW I would have microbiology spring 2016
