Which of the following describes PPNG gonococci characteristics?

Penicillinase-producing Neisseria gonorrhoeae (PPNG) are a specific type of gonococci that have developed resistance to penicillin due to the production of the enzyme penicillinase. This enzyme breaks down penicillin, rendering it ineffective as a treatment for infections caused by these bacteria. The presence of penicillinase is a key characteristic that defines PPNG, making option B the correct choice.

This characteristic is significant because it illustrates the adaptive mechanisms bacteria can employ in response to antibiotic pressure. Understanding this resistance helps in guiding treatment plans for patients with gonorrhea, as alternative antibiotics may need to be considered to effectively treat infections caused by these resistant strains.

In contrast, the other options do not accurately represent PPNG characteristics. For instance, while some gonococci may exhibit resistance to certain antibiotics, they are not universally resistant to all antibiotics. Additionally, PPNG can be found in both male and female genital tracts; they are not exclusive to the female population. Lastly, Neisseria gonorrhoeae are facultative anaerobes, meaning they can grow in both aerobic and anaerobic conditions, but they do not require anaerobic conditions exclusively for growth.
