Abstract:
Streptococcus agalactiae is an important microorganism involved in a number of conditions in pregnant women, newborns, elderly people (over 65 years of age) and individuals with chronic disabling illnesses. This pathogen is infrequently found among patients outside this age range or clinical profile(1-5) and is rarely reported in the etiology of sexually transmitted diseases. Here we describe a case of an otherwise healthy 19 year-old male, who presented with ulcerative genital and oral lesions in association with urethral and ocular discharge, suggestive of Streptococcus agalactiae infection acquired through sexual contact.
Insights
Streptococcus agalactiae, typically affecting pregnant women and the elderly, can cause sexually transmitted infections. This case highlights a rare genital and oral infection in a young male, suggesting sexual transmission.
Area of Science:
- Infectious Diseases
- Microbiology
- Urology
Background:
- Streptococcus agalactiae is a significant pathogen primarily affecting pregnant women, newborns, the elderly, and immunocompromised individuals.
- Infections outside these groups are uncommon, and its role in sexually transmitted diseases is rarely documented.
