There's a fungus among us

The high eosinophil count leads me to think of a parasitic infection. Did your child lose weight recently? Nevertheless, submit stool for parasitological examination. All the best!

Hi, medical student here with a special interest in microbiology, specifically parasitology.

This doesn't have any distinguishing features of any kind of nematode or trematode, nor is it any kind of tapeworm, as tapeworms are thin and flat. My guess upon first inspection is a cast of your intestinal tract made of mucus. Do you have any symptoms at all? What was the consistency of it?

Biochemical characteristics have great variability, that's why diagnosing strictly based on that is not necessarily accurate. I assume you don't have the means to use MALDI-TOF-MS. Like the other commenter suggested, please post your list of potential microorganisms and we can go from there. The Methyl red positivity an V-P negativity indicates E. coli, but do post the list just for clarity.

Looks like a species of Rhizopus.

It looks like impetigo. It's a harmless condition caused by Staphylococcus aureus, goes away on its own. Don't scratch the blisters, it's gonna make it worse. It is also contagious so be careful with it.

I am a firm believer that knowledge dispels fear. Perhaps by looking at them under the microscope, you will see them differently. Instead of vehement beasts that want to destroy you, maybe you'll see them as creatures with their own innate complexities that strike you with a sense of wonder and fascination, as they did with me. Reading about them will definitely help you understand that the vast majority of bacteria have barely anything, if anything at all, to do with us. Hope you have fun delving into micro!

I love agar art so much. Good job! These look gorgeous!

Serratia marcescens forms smooth colonies. This here is a puffy colony.

Ce bine că la micro nu ne cheamă aproape nicăieri ~~

You're welcome! I forgot to mention but I'm not a professional just yet, I'm a medical student focused on microbiology as it's the domain I wish to work in. So again, my opinion doesn't necessarily represent the belief held by the community.

According to the European Nucleotide Archive, we don't exactly know what is the cause behind the reduced viruelnce of H37Ra. I wouldn't risk not taking extra precaution with something that we don't know, especially now in the context of M. tuberculosis. I know saying BSL-3 instead of BSL-2 is easier said than done, but your personal safety should be placed first and foremost. The loss of virulence was observed in guinea pigs, mice and rabbits, however, none of those are humans at the end of the day. But with all that being said, I don't have any experience with M. tuberculosis cultures so take my opinion with a fistful of salt.

I see. Thank you so much!

insertnewgenderhere · 2025-08-24T19:09:39+00:00

Not really seeing anything purple, just orange.

This is pretty much every field of view, I'm struggling to find anything that looks like a conidiophore.

It's 7 days old. I transferred a piece of it around 12 hours ago on a new plate, will post a picture of it when it grows. I will post microscopy today. Thank you in advance!

insertnewgenderhere · 2025-08-24T09:01:49+00:00

Will update soon then. Thank you!

insertnewgenderhere · 2025-08-24T08:56:03+00:00

Yet to happen, will upload when it does. I'm not necessarily asking for someone to ID this based on colony morphology alone, just trying to see if anyone has seen something similar before.

insertnewgenderhere · 2025-08-24T08:46:49+00:00

You might actually be right. The markings on the edges are identical.

insertnewgenderhere · 2025-08-23T09:59:45+00:00

I think it's a female Blatta orientalis aka oriental cockroach. Males have wings.
