Final answer:
Two separate dacron swabs are typically used, one for N. gonorrhoeae and another for Chlamydia when collecting samples for testing.
Step-by-step explanation:

This is because they are two different types of bacteria that cause different infections. While collecting the sample, one swab is used for N. gonorrhoeae and another swab is used for Chlamydia.
