Read the case study below and then use your microbiology expertise to determine which pathogen is causing the symptoms. The results will be shared on August 1, 2019.

Good luck!


Determining which sexually transmitted infection (STI) is causing uncomfortable or painful symptoms isn’t always simple. Many STIs present with similar symptoms, and physical examinations may not reveal the culprit.

Case Study:

A 37-year-old male presents with burning during urination. The patient has exhibited dysuria for the last 8 years, and he has been with same partner for 12 years. Multiple STI screens and urine cultures have been performed. He has tested negative for chlamydia, gonorrhea, and Trichomonas on each screen and a urine culture yielded no pathogenic growth. A physical examination yielded no visible symptoms. The patient was treated multiple times for non-gonococcal urethritis unsuccessfully and symptoms continue to persist.

    Mycobacterium genitalium Is not a well known causative agent of STI. It’s proved resistance to most known antibiotics. Symptoms are not distinguishable from chlamydiasis and gonorrhea. And diagnosis is not feasible. So maybe the doctor never suspected it and didn’t include it in the diagnosis.
