A clinical microbiology laboratory is using a nucleic acid amplification test (NAAT) to detect Mycobacterium tuberculosis directly from sputum. A positive result indicates:
정답: D
A clinical laboratory performs a cefoxitin disk diffusion test on a Staphylococcus aureus isolate from a wound culture. The zone of inhibition measures 18 mm. According to current CLSI M100 guidelines, how should this result be interpreted regarding oxacillin/methicillin susceptibility?

A Klebsiella pneumoniae isolate from a bloodstream infection shows the following susceptibility profile:
Meropenem (MIC = 8 µg/mL, R), Imipenem (MIC = 16 µg/mL, R), Ertapenem (MIC = 4 µg/mL, R), Ceftazidime/avibactam (MIC = 1 µg/mL, S), Aztreonam (MIC = 32 µg/mL, R). Which resistance mechanism is most strongly suggested by this pattern?

A traveler returning from sub-Saharan Africa presents with cyclical fevers, chills, and sweats. A Giemsa- stained peripheral blood smear reveals multiple ring forms within red blood cells, some applique forms, and occasional banana-shaped gametocytes. No Schüffner's dots or red blood cell enlargement is observed. Which Plasmodium species is the most likely cause?
정답: A
A patient with HIV infection and a CD4+ T-cell count below 50 cells/µL develops a progressive neurological illness characterized by confusion, motor deficits, and seizures.
