Definition
Associated with water
Will grow in increased salt concentration (some spp are halophilic meaning they require salt)
Identified only by request. Specimen needs to be collected before administering antibiotic therapy and transported to the lab immediately because they are sensitive to drying and pH changes |

Comma-shaped
Causes severe watery bacteria by producing enterotoxin
Was originally called Kommabacillus
Transmitted from fresh and salt water exposure and food cooked in contaminated water |

|
Term
| Pathophysiology of cholera infection |
|
Definition
| Organism produces enterotoxin which disrupts the normal function of intestinal mucosa and the toxin attaches to epithelial cells to activate CAMP which prevents the reabsorption of Na+ that results in "rice water stools" |

Term
| V. cholera identification |
|
Definition
| Yellow colonies and sucrose pos on TCBS. Non-halophilicm string test and shooting star motility |
|
|
Term
|
Definition
| Used as transport media for vibrio cholera. Decreased pH suppress the growth of other bacteria. |
|
|
Term
|
Definition
| Used for identifying vibrio cholera. Suspend the organism in 1 drop of 0.5% sodium desoxycholate (Bile solubility reagent) cholera will be positive and form a viscous string |

Term
| Serotyping of vibrio cholera |
|
Definition
Based on the O somatic antigen
2 serogroups: 01 and non 01
01= intestinal disease
non 01= extra-intestinal infections |

Hikojima
2 biogroups: Classical and El Tor
El Tor is the most severe |
