A stool sample is collected from the patient and sent to a laboratory. There, it is incubated on various culture media to promote the growth of microorganisms. The process involves several steps: 1. Sample Collection: The patient collects the stool sample in a sterile container. 2. Incubation: The sample is incubated at specific temperatures to encourage bacterial growth. 3. Identification: Microbiologists use biochemical tests and microscopy to identify the organisms present.
