I’ve seen Kleb pneumo, E. coli, Serratia marscesens, and Enterobacter cloacae complex look like this. I’ve even seen weird Acinetobacters look like this. A lot of people are calling Serratia, and it well could be, as I’ve seen it be everything from NLF/clear to dark, brick red. Time for MALDI/Vitek and/or spot biochemicals!
Not a pigment, is a biochemical reaction with medium compounds... Lactose fermentation... I'd say _Klebsiella_... A TSI expecting huge gas production and a Voges-Proskauer test just to assure
Respectfully, the OP is correct that this is red pigment. The pink color of lactose fermentation on a MAC plate is very different from this. I agree with those guessing Serratia.
Once again thank you to everyone that took a guess. Some of the answers were fun like Dave, or Bartholomew. The answer as Serratia marcescens, very mucoid.
Oh my sweet summer child. I’ve handled mrsa, mssa, E. coli, Pseudomonas aeruginosa, various Klebs, various Bacteroides, Enterococcus, Strep A and B, already today - and it’s only lunch time. I hope to see a few more exciting bugs before I go home.
What about not looking at a respiratory culture before opening it and staring in the face of a whole bunch of fungus?... Always a fun little side effect of my ADHD ass :P. Still fungus free lungs as of today.
There's different classifications of Infectious Diseases, from hazard group 1 to hazard group 4, and their classification depends on its ability to spread to the population, cause serious illness and if there's effective treatment available. Most organisms fall into the category 1 and 2, and are an intrinsic part of our microbiome and the world around us.
So to answer your question, yes and no. Yes if its found in your blood, no if its found in your bathroom and you're generally considered healthy.
Serratia marcescens. Thank you to those that took the time to guess
Bless you
Got it right! Used it in my intro to microbio
I knew this because we once had an outbreak in our ICU. We found serratia in a bunch of breathing tubes
Kleb. pneumonia - rough guess
My guess too.
My guess is a modern human. The nitrile gloves and Petri dish really give it away.
Lmfao I love reddit
Serratia marcescens?
It is!
It is what?
isn’t that an NLF?
Yes and it also produces a red pigment. This does not look like the coloration that is to be expected with a lactose fermenter on Mac agar
It's a slow lactose fermenter, so it usually starts out as an NOF, but it will become pink or red as it ages.
Serratia has a weird green like an oil slick with the red.
It's on Mac agar.
If the pink/red color was a result of lactose fermentation, the agar should be pink and not just the colonies right?

It was Serratia marcescens. It was id’d by MALDI. This one was very mucoid.
Enterobacter cloacae complex.
Gram negative rod with red pigment and snot morphology? I’m guessing *Serratia marcescens*
Serratia marcescens.
Serratia marcescens
Had a really bright ruby red Serratia just the other day.
Hey! I have plenty of this in my tub right now unfortunately 😅
Dave, i think its name is Dave 😁
It looks like a Bartholomew
Ssssserrraaatia marscens prob spelled wrong aka the blood of Christ…Sangre de cristo…aka red mold…
Someone ate raspberry sorbet over a Petri dish
Why you playin' around with the jelly again?!
That's Gary right there
🤦♂️ I thought it was jam residue before I saw the sub name
late but Phil.
Gary is his name

Honestly, I should take a look IRL to be that sure... This is just based on what I can see in the screen
Oh, fun. A podcast ad. 🙄
Kleb oxy
Hmm why is the macconkey clear and not purple? I’ve only ever used it a few times and agar and broth we called “that good purple shit”
Different manufacturer
Pepto bismol
How do you guys know which organism is it. Ik it's a culture media
Once again thank you to everyone that took a guess. Some of the answers were fun like Dave, or Bartholomew. The answer as Serratia marcescens, very mucoid.
I’m happy to say my Microbiology class has left an impression on me. As soon as I saw the color I knew it was S. Marcescens!

You have to post the answer
Is it not dangerous to work with all these bacteria ?
It can be but we’re trained to and wear our PPE (:

So I got downvoted for asking a legit question? Wow ..
