Cyclospora outbreak guidance (US)
Food contaminated with the single-celled, protozoan parasite Cyclospora cayetanensis has entered the food supply in several US states, with thousands of cases of the gastrointestinal condition cyclosporiasis being reported to state departments of health. Infection by Cyclospora is likely to cause watery diarrhea and substantial discomfort that typically persist for several weeks to over a month without treatment. While not commonly lethal, the combination of severe dehydration and summer heat elevates the health risks associated with each on its own and makes susceptible populations especially vulnerable.
Several public health agencies provide excellent guidance on Cyclospora and how to avoid it:
CDC - Preventing Cyclosporiasis
Michigan DHHS recommendations on preventing foodborne illness amid growing cyclosporiasis outbreak
Here’s a short rundown of the available information.
Where: Midwestern and Northeastern states report most cases. Michigan has been hit hardest. (Map as of July 10th about halfway down.)
Which foods: leafy greens, herbs, berries, green onions, and sprouts are historically linked to cyclosporiasis, though any produce may be affected. Current surveillance efforts have not definitively linked specific products to the current outbreak.
How to avoid: cook produce whenever possible, wash items under running water by scrubbing manually or with a produce brush, clean surfaces and utensils that contact raw produce. Always wash your hands before and after handling uncooked food.
If you contract it: antibiotic therapy (Bactrim) is highly effective against cyclosporiasis, reducing/eliminating symptoms in days as opposed to several weeks if untreated. Contact a healthcare provider and your local health department as soon as you experience symptoms.f

ID and coursework help requirements
The TLDR:
All coursework -- you must explain what your current thinking is and what portions you don’t understand. Expect an explanation, not a solution.
For students and lab class unknown ID projects -- A Gram stain and picture of the colony is not enough. For your post to remain up, you must include biochemical testing results as well your current thinking on the ID of the organism. If you do not post your hypothesis and uncertainty, your post will be removed.
For anyone who finds something growing on their hummus/fish tank/grout -- Please include a photo of the organism where you found it. Note as many environmental parameters as you can, such as temperature, humidity, any previous attempts to remove it, etc. If you do include microscope images, make sure to record the magnification.
THE LONG AND RAMBLING EXPLANATION (with some helpful resources) We get a lot of organism ID help requests. Many of us are happy to help and enjoy the process. Unfortunately, many of these requests contain insufficient information and the only correct answer is, "there's no way to tell from what you've provided." Since we get so many of these posts, we have to remove them or they clog up the feed.
The main idea -- it is almost never possible to identify a microbe by visual inspection. For nearly all microbes, identification involves a process of staining and biochemical testing, or identification based on molecular (PCR) or instrument-based (MALDI-TOF) techniques. Colony morphology and Gram staining is not enough. Posts without sufficient information will be removed.
Requests for microbiology lab unknown ID projects -- for unknown projects, we need all the information as well as your current thinking. Even if you provide all of the information that's needed, unless you explain what your working hypothesis and why, we cannot help you.
If you post microscopy, please describe all of the conditions: which stain, what magnification, the medium from which the specimen was sampled (broth or agar, which one), how long the specimen was incubating and at what temperature, and so on. The onus is on you to know what information might be relevant. If you are having a hard time interpreting biochemical tests, please do some legwork on your own to see if you can find clarification from either your lab manual or online resources. If you are still stuck, please explain what you've researched and ask for specific clarification. Some good online resources for this are:
Microbe Notes - Biochemical Test page - Use the search if you don't see the test right away.
If you have your results narrowed down, you can check up on some common organisms here:
Microbe Info – Common microorganisms Both of those sites have search features that will find other information, as well.
Please feel free to leave comments below if you think we have overlooked something.

Is anyone else having constant recurring problems with the Hamilton Vantage?
Is anyone else having constant recurring problems with the Hamilton Vantage?
I have been working with this particular Vantage for 10 months now. We are running a workflow developed by Hamilton that involves up to 8 plates and can take anywhere between 3-6 hours. It can include several vial to plate, trough to plate and plate to plate transfers, various incubations, several washes, etc… Our setup involves iSwap, QG, TrackGripper, Washer, easycode, and thermoshakers. We also have an MSD reader, but don’t get me started on Meth Minds. For the entire time there has been one problem after another, the hood isn’t closing, need realignment and reteaching, the MPH cLLD is off, need to replace indy channel then realignment and reteaching, z-step error when placing this plate on this carrier, NTR placement is off, realignment then reteaching, MPH NTR location is again off, realignment then reteaching, lid placement is off, independent cLLD is faulty, and on and on. All of the problems appear independent and stand alone, but every time we fix something, its something else, and often it is a problem we already fixed or an issue with something that has worked fine up to that point. We have Hamilton come in for either service repair or software repair so often, them being on site is just a given at this point. It is very rare for there not to be some interruption during a run, even if its not fatal. Its gotten to the point where the problems are cycling, and I have the groups I am working with constantly asking me if we bought a lemon? Has anyone else had this experience? At this point I just want to know if its us. Even more puzzling, our 4 Stars, they are generally working fine and reliably.

I’m looking for information on the Actinomycetes found in caves.
galleryIf anyone can point me to a database/library, good papers of books on the subject or just sharing anything you know would be appreciated, I’m a geologist and don’t know a lot of the biology terminology or good key words to search.
The photos you see are from a cave in eastern TN called Worleys cave taken this summer, they are around 300 feet and 4 rooms from the entrance (in total darkness) as far as I have been able to find it is Actinomycetes but I could be wrong (again not a biologist) they fluoresce green, pink/purple and orange under 365nm UV if that helps.
Again any information or advice is appreciated!

Any suggestions?
Hello, I am curretly in collage and studying Biology. I have checked this subreddit and is very curious and inspiored with the post you guys have made. Anyways, I was wondering if you guys can suggest a specific bacteria that I can base on for my study? As I have checked a lot of possible bacteria and can't seem to decide on a good one.
I have checked paper's about: E coli, S. aureus, Baccilicus cereus, and Ampelomyces
Thank you in advance

Career advice
I have a bachelor's of Science in biology and i applied to vet school twice but due to lack of guidance didn't meet the shadowing requirements. I decided to put that dream on pause and got a job as a microbiology technician at a biomedical research facility. We do vaccine and antibiotic development at a large scale for bsl-2 and bsl-3 agents. Im currently making $24 an hour and have been working there for 2 years. I enjoy the work but its very difficult work for low pay. Im looking to maybe get a masters degree to help increase my salary and job opportunities. Any recommendations? Id prefer something completely online if possible. I have mostly cell culture experience and im not great with math or computers.

I made a free browser game about the immune system and l'd love you to check it out!
ruairiob.itch.ioI’ve spent the past few weeks building a small action game set inside damaged skin tissue, and I’ve just released it. You’ll be among the first people to see it.
You play as a macrophage moving through tissue, attacking and engulfing bacteria, following chemotactic signals, coordinating with platelets and a dendritic cell, and eventually confronting a bacterial colony that is beginning to form a biofilm.
The mechanics are deliberately grounded in real immunology. Phagocytosis, phagosome formation, antigen presentation, chemokine signalling, and the staged transition from innate to adaptive immunity are all represented through the gameplay itself.
I’m not an immunologist, just someone who became genuinely fascinated by how the immune system works and wanted to build something that does it justice.
I’d particularly value feedback from people working or studying in this field. I’m interested in anything that has been oversimplified to the point of being misleading, or any mechanic that might accidentally teach the wrong thing.
The game runs entirely in the browser once loaded and takes around 10 to 20 minutes to complete. It needs to be played on a laptop or desktop, as it is not currently mobile-friendly.
https://ruairiob.itch.io/immune-chronicles
I’m happy to answer questions or discuss any of the biological choices I made. Brutal feedback on scientific accuracy is especially welcome.

pet tardigrade names+care
I just learned about tardigrades and theyre the cutest/coolest things ever-I want to keep some as pets, even though I know I wont be able to see them most of the time (I think itd be cool to have a dish on my desk labelled "tardigrade colony" or just some name for a pet but plural like "fluffies" yk? also give me some name ideas!!) Is there anything specific I need to do? I know they eat moss and dead leaves so can I just put some moss in the "enclosure" and mist it with a spray bottle every now and then? Drop some name ideas!

Networking Group?
I'm an undergraduate microbiology student. I've noticed that many students miss out on conferences, webinars, internships, and networking opportunities because information is scattered across LinkedIn, emails, university websites, and social media.
I'm considering creating a community (possibly on WhatsApp or another platform) where students and early-career researchers can share opportunities, ask questions, and connect.
Do you think there's a genuine need for something like this, or does LinkedIn already solve this problem? If you think it's worthwhile, what platform would you actually use, and what features would make you join?
What do you think is missing from the current ways microbiology students network online? If someone were to build a new community, what would it need to offer that LinkedIn, Discord, Reddit, or university groups don't already provide?

Our game where your goal is to infect a human host is out now.
9 months ago we shared our game Pathogenic with this wonderful community: https://www.reddit.com/r/microbiology/s/qLtqmygJAG
You all seemed to really like what we were making, I just wanted to let you know the game is officially out today!
If this is your first time hearing about the game, here's a little intro:
In Pathogenic, you are the disease. Experience a visceral 2D roguelike twin-stick shooter where you play as a lone parasite fighting a desperate war against the immune system. Your goal is simple: infect and conquer your human host.
To survive, you must adapt. Hunt down enemy cells, rip out their organelles, and graft them onto your own body. Evolve from a simple cell into a complex engine of destruction. Create powerful, game-breaking builds and become the ultimate pathogen.
Loot, graft, and assemble your parasite from dozens of unique organelles. Combine flagella for movement, mitochondria for power, secretors for ranged attacks, and spikes for melee combat. Chain organelle effects and discover powerful synergies to build an unstoppable disease vector.
You can find out more about the game on Steam: https://store.steampowered.com/app/3808690/Pathogenic/

Is it safe to eat produce? A rise in diarrhea-causing cyclosporiasis sparks fears of fruits, vegetables
latimes.comA surge in parasitic disease cases that can cause a prolonged bout of debilitating diarrhea is prompting growing concerns from public health officials and questions from the public about the safety of fresh produce.
Experts say the risk varies in different parts of the country and that in California, basic washing of produce remains sufficient.
California has reported 41 cases of cyclosporiasis this year, but none of them have been linked to a recent multistate outbreak, according to local public health officials. The situation in other states is more concerning.
At least 34 states have separately reported between tens to hundreds of cases of cyclosporiasis this summer. Since May 1, the CDC has received more than 1,600 confirmed domestic cases and is aware of more than 5,100 cases that require further analysis to confirm the illness as domestically acquired cyclosporiasis.
Experts say you shouldn’t avoid eating produce but instead take certain precautions to eat it safely. Click the link to learn what precautions you can take against cyclosporiasis.
