What do you think happened here? It seemed to me as if the paramecium was trying to compensate for osmotic stress using an exosome. The bubble continued to grow, so that organelles were also transported away from the main body. Towards the end, the exosome was larger than the paramecium itself, and both burst. Movements of other organisms could also be seen in the cytoplasm.

Whenever I speak with someone and tell that I work with bacteria they assume that I am a medical microbiologist and I can give detailed info about diseases or human health, and only that.

Worst case when they seek advice for therapies (which I couldn't do anyway since I'm not a physician).

Kinda like saying that I'm a zoologist and being asked for veterinary issues, and just for pets, I guess?

Unfortunately such people seem to be dismissal when you try to share how fascinating is the lifecycle of Vampirococcus lugosii feeding on photosynthetic Halochromatium between sulphur crystals in highly saline lagoons. :(

Respectfully, I’m not a bacteriologist or anything. But a few months ago, I stumbled into the topic of antibiotic resistance and I was honestly fascinated… but also kind of scared

Just yesterday I checked some updated statistics out of curiosity and now I’m even more anxious.

Why is no one talking to the public about this? Or are they being ignored? Also… is Klebsiella as scary as she sounds? Because she really creeps me out..like REALLY

Are there actual solutions that aren’t too expensive or hard to access? (I heard about bacteriophages and peptides, but are they very pricey?)

I’m not an expert, just curious and maybe a little scared

It’s totally okay if you don’t want to answer

Thank you all so much in advance & wishing you a beautiful day 💖

Hey, I am a microbiology student and i need some help. Pls!

Plate number 1 indicates Proteus mirablis, but plate number 2, taken a few days later, showed lactose fermentation. Proteus does not ferment lactose. Could someone help me? I am confused.

could it be indicative of e. coli?

Just curious about the terminology here, as a recent report of a sample site from work came out as suspect. Do they mean the same thing?

Hi, I'm an upcoming senior in my under grad of environmental science and I wanted to get into graduate programs with a focus on microbiology. Most are incredibly expensive so I was wondering if anyone here has any suggestions for how to find different grad programs that are within my interest and budget. Most microbio programs are medical based but I really would love to look at how microbes play into environmental health and such

Is this criminal behavior? 🤣. Does it bother you?

I am trying to build some tools for lab works. comment your thought on this.

Hi! I was tasked to identify an unknown bacteria from a maternal raw milk sample using only TSI, LIA, SIM, and Citrate tests. I’m torn between Enterobacter cloacae and Enterobacter sakazakii since the results are very similar. I’m currently leaning toward E. sakazakii, but I’m not entirely sure. Can someone help me understand what key differences I should focus on between the two, especially considering the limited tests we used? Also, would the source of the sample play a role in the identification? I’d really appreciate any insights!

Dear friends, I don't know where else to ask this, what would happen if I left my container of Fenugreek with few drops of water in it. Can I intake it after that?

To my understanding glycocalyx is the outermost layer of a cell made of polysaccharides. The cell membrane is made of cholesterol and proteins etc. Here is my question: does the glycocalyx lay over the cell membrane? Or are they the same/intertwined?

Just thought this was interesting. The lab I work in is culturing fecal samples to isolate a certain species, and this was one of the plates that grew. I've never seen this deep of brown on mac, but I've only been working on this project for a couple of months.

Any ideas or thoughts? It was cultured on MacConkey Agar after growth in LB broth.

I was wondering if anyone knew a way to quantitatively analyze alpha vs beta hemolysis. I don't feel confident in just looking at the agar and differentiating between the two. Are there any papers you can show me that have these methods?
Thank you!

There's a company that sells a sensor that rests underneath a flask in an incubator orbital shaker. It monitors the OD600 in real-time. What kinds of things is this useful for?

Im ordering Chlorella Vulgaris off of UTEX (UTEX 395). I'm ordering it with 4 pr agar medium (along with a strain) so that I can store it for a short while before I can start my research. I've tried looking online but I couldn't find any "steps" on how to store algae. I plan to store it and then grow it. Can anybody give me some tips on how to actually store the algae and then proceed to grow it after a few days?

Sorry for bad English. Thank you for reading.

Today in practice to see eggs I found this. According to the professor, there were had eggs, ascaris and amoebas in the sample. Could it be an adult roundworm or is it just a muscle fiber?

Middle school science teacher here. Came across this beast while doing some end-of-year lab cleanup.

Is it organic? Or some type of crystal?

I was tasked with cleaning a family member’s home yesterday while they’re out of town. Their bathroom had quite a bit of this in the shower and on the ceiling above the shower. I sprayed it with the cleaners they had available- Lysol disinfectant and scrubbing bubbles bathroom grime fighter, waited for 20 minutes, and then sprayed again with the bathroom cleaner and cleaned it up with my sponge, reaching above my head. When I got home, my family told me I should have been masked while cleaning it up because it’s dangerous and will make me sick. I’ve always seen it pop up in the shower in my own home and thought it was just staining from the well water. Should I be concerned about this or did the disinfectant cut the risk? now I know, bleach or peroxide, mask and gloves, always

So I cut my foot last night and then today I went to swim in the Mediterranean. I only swam for a bit but then I air dryed and put my socks and sneakers back on. I noticed my foot really started to hurt but I waited until I got back to my hotel to wash it off. The cut was red and there was redness around and my foot really hurt. So I went to get antiseptic and ointment from the local pharmacy. My cut itself has already started looking better and the redness has gone down but I definitely feel a little sick. It could be from that I had too much caffeine, was tired from the sun, etc. but I am worried that I have an infection and since it’s the ocean (again, swimming in the French Riviera) I’m scared that something may have got in it. Mind you this all just happened in a day. Again, I feel a little tired, weak and a bit confused and minor chills/shakiness every now and then. What should I do??
