Abstract:
Urethritis caused by Neisseria meningitidis in heterosexual patients is presumed to occur via orogenital contact, but confirmation has not been possible in most cases. Presented here is a case of urethritis caused by N. meningitidis, serogroup C, and the isolation of the same microorganism from the nasopharynx and endocervix of the patient's sexual partner. The similarity of the urethral and nasopharyngeal isolates' electrophoretic patterns, obtained using pulsed-field gel electrophoresis, proves the infection was transmitted via orogenital contact.
Insights
Neisseria meningitidis can cause urethritis in heterosexual individuals, likely through orogenital contact. This study confirms transmission by isolating the bacteria from a patient and their sexual partner, matching genetic profiles.
Area of Science:
- Microbiology
- Infectious Diseases
- Sexually Transmitted Infections
Background:
- Urethritis is inflammation of the urethra, often caused by sexually transmitted infections.
- Neisseria meningitidis typically causes meningitis but can be associated with other infections.
- Orogenital transmission of Neisseria meningitidis causing urethritis is suspected but rarely confirmed.
Observation:
- A case of urethritis caused by Neisseria meningitidis (serogroup C) in a heterosexual patient is presented.
- The same Neisseria meningitidis strain was isolated from the patient's sexual partner's nasopharynx and endocervix.
- Pulsed-field gel electrophoresis revealed identical electrophoretic patterns between urethral and nasopharyngeal isolates.
Findings:
- This study provides definitive evidence of Neisseria meningitidis transmission via orogenital contact.
- Confirms a non-genital site (nasopharynx) as a reservoir for Neisseria meningitidis causing urethritis.
- Demonstrates the utility of pulsed-field gel electrophoresis in confirming infectious disease transmission routes.
Implications:
- Highlights the potential for Neisseria meningitidis to cause urethritis through sexual contact.
- Suggests screening sexual partners of individuals with Neisseria meningitidis urethritis.
- Emphasizes the importance of considering orogenital contact in the transmission of Neisseria meningitidis beyond meningitis.
