I’ll make a bigger post when I actually have it and comment on the quality.
Finished lab practical #1 last night. I think I did ok, but I did mess up a bit. Here’s where I’m predicting I lost points, and subsequently, what I’ve got to focus on.
Ran out of time before finishing 3rd streak on my streak plate. I’ve got to learn to work a little [...]
We did streak plates earlier this week and I had a blast.
I’d been looking forward to doing a streak plate since before I even fully decided to take a class. Streaking is really basic and easy, but it elegantly solves one of the earliest problems in microbiology, “How do you isolate bacteria from the hodge [...]
We did a double header today, both gram staining and acid-fast staining. Most people had about a 20% success rate, myself included.
I’m special, though. I managed to drop slide #1 into the staining tray. During staining, our slides sit on what are essentially baker’s cooling racks. We’re supposed to pick them up with high-tech slide [...]
Tonight we had an open lab; we could come in, practice anything we wanted, and ask questions about the upcoming test. I decided to get more work on the microscopes.
I crushed them, saw them driven before me, and heard the lamentation of their, uh, women.
I’m still not a master, but I had a much easier [...]
Thinking about taking in some samples from the compost pile to keep things interesting while I practice with the scope during open lab on Tuesday.
Fixed some smears from the bugs we started growing during the last lab. All the cultures showed growth, so I guess I did wait long enough for the loop to cool off. Phew.
I finally got to use a stain(methyl blue). I know it’s a little thing, but imagine spending more than a year reading about [...]
Part of the reason I’m taking a class is to find out how I like the reality of microbiology. It is easy to think of microscopy as pretty simple, especially if you’re only used to dissecting scopes or the 200x deals from middle school science class: Place slide, coarse focus on low magnification, switch [...]
