Researchers of a bacteriological laboratory examine tinned meat for botulinic toxin. For this purpose a group of mice was injected with an extract of the material under examination and antitoxic antibotulinic serum of A, B, E types. A control group of mice was injected with the same extract but without antibotulinic serum. What serological reaction was applied?
- A. Complement binding
- B. Double immune diffusion
- C. Neutralization
- D. Precipitation
- E. Opsonocytophagic
Hint
Ask what the antitoxic serum does to the toxin inside the animal, and how survival of the protected group compared with the control group reveals the result.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
