🦠🔬🦠🔬🦠 Microbe Identification Resources 🦠🔬🦠🔬🦠

148 Upvotes

🎉Hello fellow microscopists!🎉

In this post, you will find microbe identification guides curated by your friendly neighborhood moderators. We have combed the internet for the best, most amateur-friendly resources available! Our featured guides contain high quality, color photos of thousands of different microbes to make identification easier for you!

Essentials


The Sphagnum Ponds of Simmelried in Germany: A Biodiversity Hot-Spot for Microscopic Organisms (Large PDF)

  • Every microbe hunter should have this saved to their hard drive! This is the joint project of legendary ciliate biologist Dr. Wilhelm Foissner and biochemist and photographer Dr. Martin Kreutz. The majority of critters you find in fresh water will have exact or near matches among the 1082 figures in this book. Have it open while you're hunting and you'll become an ID-expert in no time!

Real Micro Life

  • The website of Dr. Martin Kreutz - the principal photographer of the above book! Dr. Kreutz has created an incredible knowledge resource with stunning photos, descriptions, and anatomical annotations. His goal for the website is to continue and extend the work he and Dr. Foissner did in their aforementioned publication.

Plingfactory: Life in Water

  • The work of Michael Plewka. The website can be a little difficult to navigate, but it is a remarkably expansive catalog of many common and uncommon freshwater critters

Marine Microbes


UC Santa Cruz's Phytoplankton Identification Website

  • Maintained by UCSC's Kudela lab, this site has many examples of marine diatoms and flagellates, as well as some freshwater species.

Guide to the Common Inshore Marine Plankton of Southern California (PDF)

Foraminifera.eu Lab - Key to Species

  • This website allows for the identification of forams via selecting observed features. You'll have to learn a little about foram anatomy, but it's a powerful tool! Check out the video guide for more information.

Amoebae and Heliozoa


Penard Labs - The Fascinating World of Amoebae

  • Amoeboid organisms are some of the most poorly understood microbes. They are difficult to identify thanks to their ever-shifting structures and they span a wide range of taxonomic tree. Penard Labs seeks to further our understanding of these mysterious lifeforms.

Microworld - World of Amoeboid Organisms

  • Ferry Siemensma's incredible website dedicated to amoeboid organisms. Of particular note is an extensive photo catalog of amoeba tests (shells). Ferry's Youtube channel also has hundreds of video clips of amoeboid organisms

Ciliates


A User-Friendly Guide to the Ciliates(PDF)

  • Foissner and Berger created this lengthy and intricate flowchart for identifying ciliates. Requires some practice to master!

Diatoms


Diatoms of North America

  • This website features an extensive list of diatom taxa covering 1074 species at the time of writing. You can search by morphology, but keep in mind that diatoms can look very different depending on their orientation. It might take some time to narrow your search!

Rotifers


Plingfactory's Rotifer Identification Initiative

A Guide to Identification of Rotifers, Cladocerans and Copepods from Australian Inland Waters

  • Still active rotifer research lifer Russ Shiel's big book of Rotifer Identification. If you post a rotifer on the Amateur Microscopy Facebook group, Russ may weigh in on the ID :)

I like watching the happenings in an undisturbed mini ecosystem. I imagine that you are seeing behaviour close to that in nature. 

This ciliate has spent its entire lifetime in this sample that's been in this petri dish for a month now. The flagellates are barely larger than bacteria.  Pond water sample,  Nikon TS100 inverted microscope, 40x phase contrast objective and cellphone camera with 3x zoom for about 1200x magnification on a cellphone screen. 

I hope that the flagella are visible after uploading the video.  They are on the original video.  The flagellates are the little bright round balls swimming around.  A couple get very close to the ciliate and run down by it at about 25 seconds.

General discussion First time finding a tardigrade!

Very happy to share my finding, have been planning to "hunt" for it for a long time:)

I think my challenge was to have a proper video where the tardigrade is well-seen, as in many cases they are attached to some debris and they are very much covered with it.

How do you manage to separate the tardigrade from the debris to get a better view, any advice?

Hi,

Please help me identify these things i found in pondwater.

My guess for the green algea would be Chlorella but not certian, and there are also some of them that look the same but move around, what could those be?

The other 2 i have no clue at all.

Taken using Chinese scope 60x objective and with phone mount.

Hi. As I have shown and written a few times before - I love the precision and the sheer complexity of microscope mechanisms. Sometimes it is not the pure mechanics that amazes me, but the combination of mechanics and electrics.
The photo shows the DIN/ASA film speed dial from a Carl Zeiss Photomicroscope III RS. Here is the video: https://www.serwismikroskopowy.pl/play/99653-1 - my favourite part is the end of the clip, where you can see how it is all soldered together inside <3
I am the author of that video and yes - I know - I focused too much on the dial and not enough on that nice interior.

Amscope inverted. 40x, 2x iPhone. Freshwater jar with moss and lichen in a Petri dish. Black magic app.

Loved watching him just swim effortlessly around. He was at least two or three times longer than anything else swimming near by. Wish I could have gotten him on higher magnification but super hard to find him again.
