KROK 1 2019 – Question 18 · KROK (Medicine) · Microbiology, Virology, and Immunology
Urinalysis of a patient with acute cystitis shows leukocytes and a large number of gram-negative bacilli. Inoculation has resulted in the growth of mucous colonies that produce a green soluble pigment. What microorganism is the most likely cause of the patient’s disorder?
- A. Klebsiella pneumoniae
- B. Proteus mirabilis
- C. Escherichia coli
- D. Salmonella enteritidis
- E. Pseudomonas aeruginosa
Hint
Use the colony appearance and the soluble pigment in culture to identify which gram-negative rod is growing, rather than relying on the clinical picture of cystitis.
