SPECIMEN PRESERVATIVE MEDIUM BASE (SP HAJNA)

Description

Specimen Preservative Medium (SP Hajna) is designed for transport and preservation of clinical specimen. Transport media were primarily developed by Moffet et al and Stuart et al for carrying gonococcal specimens. Transport media are chemically defined, semisolid, non-nutritive, phosphate buffered media that provide a reduced environment. These media are formulated to maintain the viability and/ or infectivity of the microorganisms without significant growth during the period between collection and culture of the specimen. This medium is suitable for preserving gram-negative rods such as Salmonella, Shigella and Klebsiella. In comparative studies using Specimen Preservation Medium Base and glycerin preservation solution for different Salmonella, Shigella and Klebsiella strains, it was observed that preservation of organisms were twice more effective in Specimen Preservation Medium Base.
