question 31

Multiple Choice

A patient's vaginal specimen is sent from the walk-in clinic to the microbiology laboratory. There it is cultured on bacteriological media and then placed into an ambient air incubator set at 22% oxygen and 37 degrees Celsius. The patient is strongly suspected of having gonorrhea.

Seventy-two hours later, the culture has still not grown Neisseria gonorrhoeae so the lab reports the results back as negative. Interpret this result.

• A) The clinical personnel took the sample from an incorrect body area.
• B) The inoculating loop was too hot while streaking the specimen onto agar medium, and the bacteria were all killed.
• C) Neisseria gonorrhoeae cannot be grown in bacteriological media and requires genetic analysis for identi?cation.
• D) The culture was placed into the wrong environment for Neisseria gonorrhoeae.
