Zn-PVA, 10% Formalin, and C&S Stool transport

Description

Zn-PVA Stool Transport

• Reagent alcohol (28%) in a stabilizing solution containing zinc sulfate and polyvinyl alcohol provides an acceptable preservative-fixative for protozoan trophozoites and cysts
• The resulting permanent slide lends itself to commonly used staining procedures such as Wheatley’s trichrome or iron hematoxylin

10% Formalin Stool Transport

• Para-Pak 10% Formalin preserved specimens may be examined directly and concentrated for recovery of eggs, larvae, and protozoan cysts

C&S Stool Transport

• Para-Pak C&S is a modification of Cary-Blair, which utilizes an isotonic non-nutritive, buffered solution to insure survival of bacterial pathogens and prevent overgrowth by commensal organisms
• A pH indicator is incorporated to indicate acidic conditions in the tube which are not optimal for recovery of the organisms in question
