A propos de cet article
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.
- Fluorogenic reaction adds another dimension for thorough differentiation.
- Superior performance to TCBS; greater sensitivity and specificity.
- Molecular methods are very expensive.
Hardy Diagnostics HardyCHROM™ Vibrio is recommended for use as a selective and differential growth medium for the cultivation, isolation, and differentiation of Vibrio spp
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. The identification of species is made based on colony color and fluorescence under UV lamp. HardyCHROM™ Vibrio Agar has a high pH and salinity, which suppresses the growth of non-Vibrio species found in similar marine samples.
The Vibrio genus is comprised of Gram-negative, halophilic, non-spore forming rods that are straight or have a single, rigid curve. 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.
V. cholerae is the most well known Vibrio species, as it is the causative agent of cholera. This organism is most often transmitted via contaminated drinking water in developing countries. V. parahaemolyticus is the leading cause of bacterial diarrhea associated with seafood consumption. It is transmitted through ingestion of undercooked or mishandled seafood, or less commonly through open wounds exposed to seawater. While not as common, V. vulnificus is the most fatal Vibrio species in the United States. Infection and death from this species occurs from consumption of Gulf Coast oysters and possibly wound infections acquired in or exposed to marine environments.
