selective and Differential medium of entero pathogen is:
- A- Chocolate agar
- B- Blood agar
- C- DCA medium***
- D- Meat extract agar
- E- Non of the above.
I apologize for the repetition in my previous response. Based on the choices you provided, the correct answer is still c. DCA medium (Deoxycholate Citrate Agar).
Here's a summary of why the other options are not suitable for selective and differential isolation of enteropathogens:
A. Chocolate agar:
While it is selective for fastidious organisms, it's not specifically designed for enteropathogens and doesn't offer differentiation.
B. Blood agar:
Primarily used for differentiating hemolytic properties of bacteria, not specifically targeting enteropathogens or offering differentiation based on lactose fermentation or hydrogen sulfide production.
D. Meat extract agar:
Non-selective and not helpful in isolating or differentiating enteropathogens.
E. None of the above: Since c. DCA medium is the correct answer among the options given, this choice is incorrect.
Therefore, DCA medium remains the most appropriate choice for your question regarding a selective and differential medium for enteropathogens.
