The Para-Pak C&S (Culture and Sensitivity) provide a standardized procedure for the routine collection, transportation, and culture of stool specimens for bacterial enteric pathogens. It is designed for easy collection of specimens by individuals not trained in microbiological techniques and affords an excellent means of minimizing the adverse effects of delay in specimen transport.

Gram Stain Kits – Tissue & Film Bacteria can be classified into one of two families based upon structural and compositional differences in their cell walls. Gram-positive bacteria have thick cell walls with high peptidoglycan content, whereas Gram-negative bacteria have thin cell walls with low peptidoglycan content. Both Gram-positive and Gram-negative bacteria stain with the dye- lake formed by Crystal Violet Solution and Gram’s Iodine Solution. However, during rinsing with Decolorizing Solution, this dye-lake is completely removed from the thin-walled Gram- negative bacteria, allowing them to be subsequently stained with Safranin O Stain Solution. The short duration of the decolorization step enables Gram-positive bacteria to retain the crystal violet dye-lake. Care should be taken when rinsing slides with Decolorizing Solution, as extended rinses can cause the crystal violet dye-lake to be removed from Gram-positive bacteria in addition to Gram-negative bacteria. Within the Tissue Kit only, tissue elements are then counterstained yellow by Tartrazine Stain Solution.
