KROK 1 2013 – Question 114 · KROK (Medicine) · Microbiology, Virology, and Immunology
The laboratory for especially dangerous infections conducts microscopic examination of pathological material from a patient with suspected plague. The sample was stained by Burri-Gins technique. What property of the causative agent can be identified by this technique?
- A. Alkali resistance
- B. Capsule formation
- C. Presence of volutin granules
- D. Acid resistance
- E. Spore formation
Hint
Burri-Gins staining uses India ink, so ask whether it colours the cell or the background, and which bacterial structure would then appear as an unstained halo.
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.
