Final answer:
Neisseria infection, particularly from the bacterium Neisseria gonorrhoeae, can lead to serious complications such as pelvic inflammatory disease (PID), disseminated infection, arthritis, chronic carrier state, and meningitis if left untreated.The correct option is 6.
Step-by-step explanation:
Complications associated with Neisseria infection can be both diverse and severe. Neisseria gonorrhoeae is the bacterium responsible for the sexually transmitted disease gonorrhea, and it can lead to numerous health issues if left untreated. Among the complications are:
- Pelvic inflammatory disease (PID) - An infection of the female reproductive organs that can cause severe pain and lead to infertility.
- Skin infection - Although less common, skin manifestations can occur, particularly with disseminated infection.
- Disseminated infection - The spread of the infection through the blood to multiple organs including the heart (endocarditis) and joints (arthritis).
- Arthritis - Gonococcal arthritis is a form of joint inflammation resulting from the spread of Neisseria gonorrhoeae to the joints.
- Chronic carrier state - Some individuals can become carriers of the bacteria without showing symptoms, potentially transmitting the disease to others.
- Inflammation of brain and spinal cord - This can manifest as meningitis, which is a potentially life-threatening condition with symptoms such as severe headache, fever, and stiff neck.
These complications highlight the importance of early detection and treatment of Neisseria infections. Regular sexually transmitted infection (STI) screenings and prompt treatment with antibiotics are essential to prevent the systemic spread of the infection and the development of these serious health problems.
