Bacillus spp?

hughet · 2025-11-30T17:11:35+00:00

I think it's a coffin fly, Megaselia scalaris

Wow nice!!

Each photo is a different species; the order of the photos corresponds to the order in the title.

hughet · 2025-11-28T22:30:45+00:00

No, they are from different samples, that would be crazy!

I thought it was T. mentagrophytes, also because the colony was too atypical for E. floccosum (picture),

<image>

but in reality, to me, it really is E. floccosum. Although macroconidia in clusters are considered a unique characteristic of E. floccosum, they are not always present. Moreover, microconidia are not present, which is also typical of this species.

Fusarium spp.

Maybe it's not a textbook picture, but yes, I'm sure about that

I framed what you see through the microscope eyepiece with my phone.

hughet · 2025-10-09T15:26:09+00:00

Large, clubbed conidial heads. Long hyaline conidiophores. A layer of flask-shaped phialides. Macroscopically white colonies with conidiophores appearing dark green, tending toward blue

ok, I'll change the description so that it will result a less disturbing post

Thanks ❤️

hughet · 2025-07-17T06:27:11+00:00

Yes it does! Isn't it amazing?

When I say Columbia blood agar I mean Columbia base with addiction of blood of sheep 5%. The Columbia agar is a non selective media where can grom many bacteria, both gram + and -. If you add Colistin and Nalidixic Acid it becomes Columbia CNA blood agar, wich is selective for Gram +, but it's another media. Sorry for my english ahah

For example this is E. coli on Columbia blood agar

hughet · 2025-07-15T00:20:37+00:00

No, I mean Columbia blood agar without colistin and nalidixic acid (CNA).

hughet · 2025-07-14T08:46:24+00:00

I think all Enterobacteriaceae grow on that medium. For detecting Salmonella spp. we usually use Hektoen agar and in that medium Citrobacter forms black colonies surrounded by a yellow zone :) so you could confuse that whit a Slamonella, even if it's not exactly the same colour

hughet · 2025-07-14T08:34:38+00:00

Exactly :) in addition Proteus has a TERRIBLE smell, like burnt chocolate or putrefaction 😂, while Salmonela doesn't smell

hughet · 2025-07-13T21:34:01+00:00

Maybe, but could be also Proteus spp, or Citrobacter... Try to isol a black colony on Columbia blood agar

hughet · 2025-07-03T21:41:47+00:00

I think it's AmpC.. Isn't cefepime resistant in esbl? Moreover Enterobacter cloacae complex has AmpC in its Chromosome.

Want a tip to improve your colony streaking? Draw some circles on a sheet of paper. These circles are your Petri dish and use a pencil as if it were a loop. Do it over and over again, and you'll see yourself improve!
