Klebsiella pneumoniae, at its beautiful best on MacConkey.

Only just discovered how totally amazing @biorender.io is, wow look at these, love these so much!

Rhizopus stolonifer, five days at room temperature on MEA.

Antimicrobial disk diffusion assays are typically carried out with plain and non-supplemented Mueller-Hinton agar. However, in the case of fastidious bacteria, such as streptococci shown here, addition of 5% sheep blood can really improve growth and assay performance.

Although the yellow pigmentation of Enterobacter casseliflavus isn't that obvious when viewing the colonies growing on blood agar, picking off some growth with a cotton swab will reveal the striking yellow pigmented colonies.

Campylobacter jejeni subsp. jejuni, the most common enteric pathogen in the world. Here it is on Campy CSM. This medium is based on Columbia Agar, with supplements of activated charcoal, haematin, sodium pyruvate and three antimicrobial agents (cefoperazone, cyclohgeximide and vancomycin) to suppress the background faecal flora.

Just a thank you from @philipbutton in Melbourne, to everyone who is part of this Food Microbiology Academy community of ours.

Carbon dioxide (5-10%) enhances the growth of Brucella abortus (but not B. melitensis or B. suis, data not shown) on blood agar as seen in the first photo. Swipe to see the second image of B. abortus grown on blood agar under ambient, atmospheric air conditions.

Gram negative diplococci and erythrocytes, this is Neisseria meningitidis from a blood specimen.
