Overview
Endo Agar is an agar (solid) medium, a selective medium for food and clinical testing that suppresses competing flora and makes target colonies recognisable. Basic fuchsin differentiates lactose fermenters; used for coliform testing of water and food. STBIO manufactures it from food-grade raw materials in an ISO 22000 certified facility, with a COA for every batch.
How selective media fit into the testing workflow
Pathogen testing normally runs in three stages: a pre-enrichment medium such as Buffered Peptone Water repairs injured cells and raises numbers, a selective enrichment then suppresses competing flora, and finally a selective differential agar isolates the target colonies. Selective agents are typically bile salts, dyes, or antibiotics; differential agents make target colonies develop a characteristic colour or morphology. Choose the combination specified by the method you follow.
