Microbiology – MCQ 23 – A young male with urethral discharge

A young male patient presented with urethral discharge. On urine examination pus cells were found but no organisms. Which method would be the best for culture.
a) Mc coy cell line
b) Thayer martin medium
c) L J medium
d) Levinthal medium

Correct answer : a) Mc coy cell line

Common causes of urethral discharge in a young male are gonococcus and chlamydia. But in this case, no organisms were found in the pus cells. This indicates that the cause is probably not gonococcus. So in order to check for presence of chlamydia, we have to use cell culture methods such as Mc coy cells.
