Twelve species of Vibrio have been incriminated in gastrointestinal and extra-intestinal diseases in man, the most important of which is Vibrio cholerae
Oxoid has extended its range of products for the growth, isolation and identification of Vibrio cholerae and other Vibrio species to include alkaline peptone water (CM1028).
This liquid medium is recommended for the enrichment of Vibrio species from food and water samples.
Twelve species of Vibrio have been incriminated in gastrointestinal and extra-intestinal diseases in man, the most important of which is Vibrio cholerae.
Disease is spread through contaminated water and food.
Vibrio cholerae O1 can survive on a variety of foodstuffs for up to five days at ambient temperature and for up to ten days at 5-10C.
It can also survive freezing.
Food or water samples may contain low levels of the bacterium.
Pre-enrichment in alkaline peptone water allows Vibrio species to grow to detectable levels prior to plating on a suitable culture medium, such as TCBS (CM0333) or blood agar.
The 0.5%(w/v) sodium chloride in alkaline peptone water promotes the growth of V cholerae, while its alkalinity inhibits most unwanted background flora.
Oxoid alkaline peptone water complies with the formulation recommended for the isolation of Vibrio species in several recognised international food and water standards, including FDA/BAM, APHA, ISO 8914:1990 and the UK Environment Agency's Water Testing Methods.
