Verified step by step guidance1
Understand the term 'nongonococcal urethritis' (NGU), which refers to inflammation of the urethra not caused by Neisseria gonorrhoeae.
Recall that NGU is commonly caused by bacterial pathogens other than gonococcus, with Chlamydia trachomatis being the most frequent agent.
Review the classification of bacteria: Chlamydiae is a distinct group of obligate intracellular bacteria, different from Cyanobacteria, Spirochetes, and Actinobacteria.
Recognize that Chlamydiae includes species responsible for NGU, such as Chlamydia trachomatis, which is a major cause of this condition.
Conclude that organisms causing nongonococcal urethritis are classified within the group Chlamydiae.
