Thiosulfate-citrate-bile salts-sucrose agar has been routinely used for the isolation of pathogenic vibrios, although its selectivity for Vibrio cholerae and Vibrio vulnificus is inadequate. Therefore, a new plating medium, cellobiose-polymyxin B-colistin agar, was developed for the isolation of these two species. Cellobiose-polymyxin B-colistin agar demonstrated a significant advantage over other media designed for the isolation or differentiation of vibrios: of both the 136 strains representing 19 Vibrio species and the marine isolates of the genera Pseudomonas, Flavobacterium, and Photobacterium, only V. vulnificus and V. cholerae were able to grow. Furthermore, the fermentation of cellobiose by V. vulnificus allowed for the easy differentiation of these two species. This medium offers significant potential as a selective and differential medium for these two pathogenic vibrios.

UI	MeSH Term	Description	Entries
D010776	Photobacterium	A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that are common in the marine environment and on the surfaces and in the intestinal contents of marine animals. Some species are bioluminescent and are found as symbionts in specialized luminous organs of fish.
D011549	Pseudomonas	A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants.	Chryseomonas,Pseudomona,Flavimonas
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D005417	Flavobacterium	A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in SOIL and WATER. Its organisms are also found in raw meats, MILK and other FOOD, hospital environments, and human clinical specimens. Some species are pathogenic in humans.
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D014733	Vibrio	A genus of VIBRIONACEAE, made up of short, slightly curved, motile, gram-negative rods. Various species produce cholera and other gastrointestinal disorders as well as abortion in sheep and cattle.	Beneckea
