KROK 1 2018 – Question 5 · KROK (Medicine) · Microbiology, Virology, and Immunology
From the feces of a patient with acute gastroenteritis a pure culture of microorganisms was obtained. The microorganisms are small mobile slightly curved gram-negative bacilli that within 6 hours grow into a light blue film on the 1% alkaline peptone water. Such properties are characteristic of the following microorganism:
- A. Clostridium
- B. Spirilla
- C. Spirochaete
- D. Vibrio
- E. Bacillus
Hint
Combine the shape, motility and Gram reaction with growth in a strongly alkaline enrichment medium to decide which bacterial group fits.
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.
