Abstract
|

|
|
The purpose of this experiment is to develop a new differential medium for Vibrio cholera. The TCBS agar medium is used commonly for the identification of vibrio species, but it contains some inhibitors against other bacteria to increase the selectivity for vibrio species. So we developed the BYS agar medium as a new differential medium for V. cholera. We compared the colony forming unit(CFU) between BYS and TCBS using streak culture method and micro-pour plate method(100 ㎕). The CFU count was more than thirty times higher in BYS agar medium than in TCBS in both methods. These results suggest that BYS agar medium is a differential medium better than TCBS agar medium for the identification of V. cholera.
