Meningococcal colonisation misdiagnosed as gonococcal pharyngeal infection
The British Journal of Venereal Diseases
|October 1, 1979
Summary
Atypical meningococci can be misdiagnosed as pharyngeal gonorrhea, leading to incorrect treatment. This highlights the importance of accurate laboratory identification to avoid social and legal consequences.
Area of Science:
- Microbiology
- Clinical Diagnostics
- Infectious Diseases
Background:
- Pharyngeal gonorrhea is a common sexually transmitted infection.
- Accurate laboratory diagnosis is crucial for effective treatment and public health.
Observation:
- Three cases of pharyngeal gonorrhea were misdiagnosed.
- The misdiagnosed isolates were identified as meningococci that did not utilize maltose in CTA medium.
- Microbiological identity was confirmed through alternative methods.
Findings:
- Meningococci can exhibit atypical carbohydrate utilization patterns.
- Failure to utilize maltose in CTA medium can lead to misidentification.
Implications:
- Rare atypical meningococcal reactions pose a risk of misdiagnosing gonorrhea.
- Misdiagnosis has significant social and legal ramifications.
- Emphasizes the need for comprehensive diagnostic approaches beyond standard carbohydrate utilization tests.
