- 3 different clear and intense colony colourations thanks to its powerful chromogenic technology. Easy reading especially when compared to the conventional TCBS medium based on sucrose fermentation revealed with a pH indicator.
- V. alginolyticus remains colourless in CHROMagar Vibrio, avoiding any interference with the detection of other species.
- Clear differentiation between V. parahaemolyticus and V. vulnificus, both sucrose (-) on TCBS.
- Unrivalled medium in the chromogenic media field.
- Recovery of Vibrio is greater than with TCBS agar, even if using an enrichment broth.
- Fewer false negatives than with TCBS agar.
Gain flexibility using powder rather than ready to use plates:
Use the entire pack, or just a portion if there is a need for a smaller number of plates. If kept under appropriate storage temperature, CHROMagar Vibrio has 3 years shelf life. This flexibility is essential to avoid the waste resulting from expired-unused plates.
-Suitable with ISO/TS 21872:2007 : Microbiology of food and animal
feeding stuffs -- Horizontal method for the detection of potentially
enteropathogenic Vibrio spp. -- Part 1: Detection of Vibrio
parahaemolyticus and Vibrio cholerae ISO/TS 21872-1:2007 specifies a
horizontal method for the detection of the two main pathogenic Vibrio
species causing intestinal illness in humans: V. parahaemolyticus and
V. cholerae. Part 2: Detection of species other than Vibrio
parahaemolyticus and Vibrio cholerae. It is applicable to products
intended for human consumption and the feeding of animals, and
environmental samples in the area of food production and food handling.
-Referenced in the Chinese standard for microbiological examination of
food hygiene GB/T 4789.7-2008.

Focus on Vibrio Species
Naturally present on marine plants and animals, Vibrio
genus counts over 20 species among which four represent a serious public health hazard.
Vibrio Epidemiologic Issues
- V.cholerae, serogroups O1 and O139, often cause cholera through water and food contamination. Emerging cyclically, cholera is considered to be endemic in many countries as a virulent disease causing severe diarrhea and dehydration. The number of cholera cases reported to the W.H.O. in 2006 rose dramatically, reaching the level of the 1990s. Around 240,000 cases were reported from 52 countries, including about 6300 deaths.
- V. parahaemolyticus and V. vulnificus are largely involved in foodborne diseases from seafood, causing septicaemia, wound infections, and gastroenteritis. CDC reports an estimated 47% increase of Vibrio infections in the US (1996-1998 to 2008), about 8000 illnesses yearly. Vibrio infections are also commonly reported in areas of Asia and Oceania, linked to the high consumption of seafood. Despite the fact that V. parahaemolyticus is the most commonly reported species causing infection, V. vunificus has become increasingly prevalent and is now associated with 94% of reported deaths.
- V. alginolyticus is less common but is a major pathogen issue for oyster producers since it can lead to major production losses. If detected, it can prevent contamination of other oyster production sites.
