Modified Stuart Transport Medium for Pathogenic Specimens

Modified Stuart Transport Medium is a dehydrated, semi-solid transport medium formulated for the collection, transport, and short-term preservation of pathogenic bacterial specimens.

This modified formulation contains methylene blue and does not contain activated carbon, allowing visual monitoring of redox conditions while maintaining microorganism viability during transport. It is suitable for routine microbiological specimen handling prior to laboratory examination.
