About PetriKey

PetriKey is a microbiology study reference: 341 organism and concept entries, each with its Gram reaction, morphology, lab clues and high-yield hook, plus flashcards, quizzes, identification flows and a small set of long-form guides.

Where the entries come from

Each entry is one record in the site's dataset, and the organism pages, flashcards, quiz, Gram cross-cuts and printable study sheets all read from that record, and the Gram pages group organisms by stain result and by stain and shape together. At the foot of each organism page is the list of sources the record cites, drawn from OpenStax, NCBI Bookshelf, CDC, CDC DPDx, WHO, and ICTV, with a link to each.

Who runs it

PetriKey is built and kept by one independent developer, who also makes LabVals, DoseDrill, AnatoMemory and TermDecode. No individual signs a PetriKey guide; the site's name stands in that place, and the structured data credits the PetriKey organization. No microbiology or clinical qualification is claimed. PetriKey dates each guide by the newest change to its text.

What this site is not

It is pitched at what a microbiology course or a board-style question set expects, and it stops there. It is not a clinical reference, not a laboratory procedure, and not a source for diagnosis, treatment, antibiotic choice, dosing or specimen handling; it cannot tell you what is causing an infection. For clinical or laboratory work, follow your institution's validated protocols and current primary literature.
