KROK 1 2016 – Question 179 · KROK (Medicine) · Microbiology, Virology, and Immunology
A man is suffering from diarrhea. In summer he spent his vacation in the south at the sea coast. Bacteria with the following properties were detected in his feces: gram-negative curved mobile monotrichous bacilli that do not produce spores or capsules. Bacilli are undemanding to nutrient medium but require alkaline reaction (pH 8,5–9,5). Described are the agents of the following enteric infection:
- A. Cholera
- B. Colienteritis
- C. Pseudotuberculosis
- D. Shigellosis
- E. Typhoid fever
Hint
Match the shape, flagellation and unusual alkaline growth requirement, together with coastal exposure, to an enteric pathogen; most enteric bacteria grow best at neutral pH.
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.
