KROK 1 Stomatology 2016 – Question 40 · KROK (Dentistry)
While studying blood and mucus samples from the nasopharynx, a bacteriologist took certain measures to conserve the pathogens in the material. Bacterioscopic study revealed the presence of gram-negative cocci resembling coffee beans and arranged in pairs or tetrads. Name the pathogen that was isolated by the bacteriologist:
- A. Staphylococcus aureus
- B. Neisseria gonorrhoeae
- C. Moraxella lacunata
- D. Acinetobacter calcoaceticus
- E. Neisseria meningitidis
Hint
Combine the morphology (gram-negative bean-shaped diplococci) with the source of material (blood and nasopharyngeal mucus) and the need to keep the pathogen alive during transport.
