What bacteria is responsible for gonorrhea?

The bacteria responsible for gonorrhea is Neisseria gonorrhoeae. This organism is a gram-negative diplococcus that specifically infects the mucous membranes of the urogenital tract, as well as other sites such as the throat and rectum. Gonorrhea is a sexually transmitted infection, and Neisseria gonorrhoeae is known for its ability to develop antibiotic resistance, making it a significant public health concern.

Understanding the nature of this bacterium is crucial for effective diagnosis and treatment of gonorrhea. In contrast, the other options listed do not cause gonorrhea: Escherichia coli is primarily associated with urinary tract infections and gastrointestinal illness; Streptococcus pneumoniae is known for respiratory infections like pneumonia; and Chlamydia trachomatis, while also a sexually transmitted infection, is responsible for chlamydia, not gonorrhea. Thus, recognizing Neisseria gonorrhoeae as the causative agent of gonorrhea is essential for healthcare professionals in managing and treating this infection.
