Abstract:
Introduction of bacteria into the amniotic cavity has been associated with oral sex through an ascending infectious route. Previous reports have implicated both Capnocytophaga and Fusobacterium nucleatum via this process. We report a case of Streptococcus viridans intra-amniotic infection occurring at 25 weeks' gestation. Patient questioning revealed a close temporal relationship between the onset of symptoms and previous episodes of cunnilingus. The diagnosis of subclinical bacterial colonization of the amniotic fluid should be considered in patients presenting with preterm labour and no apparent aetiology. A history of recent cunnilingus may be associated with the presence of Streptococcus viridans in the amniotic fluid.
Insights
Oral sex may introduce bacteria like Streptococcus viridans into the amniotic cavity, potentially causing preterm labor. This case highlights the need to consider bacterial colonization in unexplained preterm labor, especially after cunnilingus.
Area of Science:
- Obstetrics and Gynecology
- Infectious Diseases
- Microbiology
Background:
- Intra-amniotic infections can lead to preterm labor.
- Ascending infections are a known route of bacterial entry into the amniotic cavity.
- Previous studies implicated Capnocytophaga and Fusobacterium nucleatum in infections linked to oral sex.
Observation:
- A case of Streptococcus viridans intra-amniotic infection at 25 weeks' gestation is reported.
- The patient reported recent cunnilingus preceding the onset of symptoms.
- This suggests a potential link between the sexual practice and the specific bacterial infection.
Findings:
- Streptococcus viridans was identified as the causative agent of intra-amniotic infection.
- A temporal association was noted between cunnilingus and the development of infection.
- This case expands the spectrum of bacteria implicated in ascending infections related to oral sex.
Implications:
- Subclinical bacterial colonization of amniotic fluid should be considered in patients with preterm labor of unknown origin.
- A history of cunnilingus may be a relevant factor in diagnosing Streptococcus viridans intra-amniotic infections.
- This finding may influence clinical evaluation and patient counseling regarding risks associated with certain sexual practices.
