A diatom colony. Sometimes getting an entire subject in focus is difficult with a microscope. But that’s what gifs are for.
If you’ve been following my blog for a while, you probably already know what a diatom is. But for my new followers, a diatom is a type of microscopic algae made up of two silica shells that fit like a shoebox. They are found in nearly every aquatic or moist environment, from the open ocean to the garden in your backyard. Given their ubiquity, its no surprise that these algae are responsible for large portion of the oxygen we breathe, although estimates vary.
Ok so this is probably the most unusual microscopy picture I’ve come across, but look at all those lipid droplets! Breast milk is high in fat, which is necessary for developing infants. Also, breast milk is quite rich in beneficial bacteria, which helps babies form healthy bacterial microbiomes.
(GIF) Mutated protozoa are neat! Here we have a gif of a paramecium with a mutation of some sort. You can see a non-mutated paramecium swim diagonally across the gif as a comparison.
The mutation this paramecium has seems to affect its movement, since it mostly only moved around in circles.
All kinds of algae! These were found in a canal water sample that was blooming with paramecium
Heliozoa, an aquatic microorganism. Don’t worry, they are harmless to humans despite their spiky needles. Those needles, which are referred to as axopods, serve a dual purpose. First, they snag prey (usually bacteria or algae) and then they reel it in and absorb it. More of my pictures of heliozoa can be found here
I have tomato plants in my backyard, and I noticed some of the leaves were turning purple.
Stranger yet were the small yellow bumps on the leaves. Could they be the cause of the discoloration? It’s a good thing I have a microscope to find out
The presence of two eyes tells me that at least its not a fungi
Shining a bright flashlight on top of the sample lets you see texture. They definitely look like bugs.
One was turned around. Perhaps the covering is some sort of pupae.
I scraped a few individuals off onto a microscope slide for a closer look. This one looks like it emerged completely, or maybe the covering fell off in the process of transferring to to the slide,
Here’s an intact one. I did some research on the internet and found out that they are whitelfy larvae. It’s a good thing I found them before they hatched since they can be devastating to tomato plants and can spread disease. Anyways, I tossed the infected leaf into a pond water sample. Hopefully those annoying whiteflies will drown and provide food for my microorganisms :)
I’m still not sure what caused the discoloration. There are a number of potential causes: viruses, phosphorus deficiency, and cold weather. The leaves do look neat, though:
Ahhh I’m so sorry! i seriously forgot about this and you sent it back in November D:
Well since this is a microbio blog I guess I’ll post microbio-related facts about myself
1. I’ve gotten E. coli before (the virulent strand, not the harmless strands that we all have in our gut). It was back a few years ago when I ate a hamburger. It seemed well-cooked, so I’m guessing it spread because the cooks used the same spatula to flip uncooked patties as they did to serve cooked patties (it’s a mistake a lot of people make!)
I cut meat out of my diet shortly after- I don’t want to go through that ordeal ever again. You don’t even want to know how bad it was.
2. I’ve been featured on buzzfeed! It’s one of those pop science articles, so I wouldn’t recommend taking it seriously. Anyways, my photo is the very bottom one. It’s been photoshopped to have party hats.
3. Statistically speaking, I’ve probably come across a new species of microorganism but not realized it. I have been looking at pond water samples for over a year now, after all!
4. I’ve been stung by lyngbya cyanobacteria while snorkeling in the ocean. It causes seaweed dermatitis and itches horribly. Cyanotoxins are no fun.
5. My blog name is based off of merismopedia, my favorite microorganism. I’d show a picture but tumblr isn’t letting me upload any here for some reason.
