KROK 1 2011 – Question 164 · KROK (Medicine) · Microbiology, Virology, and Immunology
Vomiting matters of a patient suspected of having cholera were delivered to the bacteriological laboratory. The material was used for preparing a "hanging drop"specimen. What type of microscopy will be applied for identification of the causative agent by its mobility?
- A. Immersion microscopy
- B. Immune and electron microscopy
- C. Electron microscopy
- D. Fluorescence microscopy
- E. Phase-contrast microscopy
Hint
Ask which microscopic technique allows living, unstained and unfixed bacteria to be watched in a drop of fluid, and which methods would kill or immobilise them.
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.
