CRITERION™ Dehydrated Culture Media, HardyCHROM™ Vibrio, Hardy Diagnostics
Supplier: HARDY DIAGNOSTICS
Hardy Diagnostics CRITERION™ HardyCHROM™ Vibrio is recommended for use as a selective and differential growth medium for the cultivation, isolation, and differentiation of Vibrio spp. from food and environmental samples.
- The only chromogenic media to differentiate V. cholerae, V. parahaemolyticus, and V. vulnificus on the same plate
- Boil to prepare the plated media; no need to autoclave
- Fluorogenic reaction, adds another dimension for thorough differentiation
- Superior performance to TCBS; greater sensitivity and specificity
- Species identification is made based on colony color and fluorescence under a UV lamp
- Perfect for environmental testing
- Wide mouth opening reduces dust formation by allowing the easy entry of a scoop
- Convenient handgrip with 'no slip' finger holds
- Stackable containers for efficient storage
- Increased solubility; dissolves quickly
The Vibrio genus is comprised of Gram-negative, halophilic, non-spore forming rods that are straight or have a single, rigid curve
CRITERION™ HardyCHROM™ Vibrio Agar is a chromogenic medium, highly selective for isolation of V. parahaemolyticus, V. vulnificus, V. cholerae and V. alginolyticus, as well as other Vibrio species. HardyCHROM™ Vibrio Agar has a high pH, which suppresses the growth of non-Vibrio species found in similar marine samples. The media consists of animal proteins, sea salts, sodium citrate, sodium thiosulfate, sugars, and a chromogenic mix. Seas salts are incorporated into the medium to provide optimum growth and metabolic activity of halophilic Vibrio spp. Sodium thiosulfate provides a source of sulfur. The inclusion of chromogenic substrates allows for the differentiation of Vibrio species based on colony color. It is the only medium that will differentiate V. vulnificus from V. parahaemolyticus and V. cholerae.
All Vibrio spp. are motile, and most species are oxidase- and catalase-positive. Several species in the genus are known human pathogens, the most notable of which are V. cholerae, V. parahaemolyticus, and V. vulnificus. Most disease-causing strains are associated with gastroenteritis following ingestion of raw or uncooked shellfish or drinking contaminated water. Cases of open wound infection and septicemia have also been reported
