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. Spirochaete
- B. Clostridium
- C. Bacillus
- D. Vibrio
- E. Spirillum
Hint
Combine cell shape, motility, Gram reaction and the speed of growth in a strongly alkaline medium to decide which genus of bacteria is described.
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.
