Abstract:
Worldwide, the incidence of bacterial sexually transmitted infections (STIs) has shown a significant increase in recent years. In Germany, this circumstance is reflected by a rise in the number of reported syphilis cases. There has also been an uptick in the incidence of non-notifiable STIs such as gonorrhea and infections caused by Chlamydia trachomatis and Mycoplasma genitalium. A key factor in the spread of these infections is their varied clinical presentation, which includes urogenital, pharyngeal and rectal involvement as well as a large number of asymptomatic cases. New real-time multiplex PCR methods allow for rapid and targeted detection of STI pathogens. The most common bacterial STI is urogenital chlamydial infection caused by serovars D-K, which affects young adults in particular. Lymphogranuloma venereum (LGV) caused by L serovars often presents as chlamydial proctitis. In recent years, Neisseria (N.) gonorrhoeae has shown a significant development of resistance, with high-level monoresistance and multiresistance to antibiotics commonly used for treatment. It is therefore imperative that sensitivity testing of N. gonorrhoeae be performed in addition to nucleic acid amplification tests (NAATs). Increased drug resistance has also been observed for Mycoplasma genitalium, a fact that complicates treatment.
Insights
Bacterial sexually transmitted infections (STIs) are rising globally and in Germany, with increasing antibiotic resistance complicating treatment. Rapid PCR methods aid detection, but drug resistance in gonorrhea and Mycoplasma genitalium necessitates sensitivity testing.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Global and German incidence of bacterial sexually transmitted infections (STIs) is increasing.
- Non-notifiable STIs like gonorrhea, Chlamydia trachomatis, and Mycoplasma genitalium show rising trends.
- Varied clinical presentations, including asymptomatic cases, contribute to STI spread.
Purpose of the Study:
- To highlight the increasing incidence of bacterial STIs in Germany.
- To emphasize the diagnostic capabilities of new real-time multiplex PCR methods.
- To address the growing challenge of antibiotic resistance in common STI pathogens.
Main Methods:
- Review of recent trends in bacterial STI incidence.
- Discussion of diagnostic advancements using real-time multiplex PCR.
- Analysis of antibiotic resistance patterns in Neisseria gonorrhoeae and Mycoplasma genitalium.
Main Results:
- Significant increase in reported syphilis cases in Germany.
- Uptick in non-notifiable STIs, including gonorrhea, Chlamydia trachomatis, and Mycoplasma genitalium.
- Emergence of high-level antibiotic resistance in Neisseria gonorrhoeae and Mycoplasma genitalium.
Conclusions:
- Rapid PCR methods offer effective STI pathogen detection.
- Antibiotic resistance in N. gonorrhoeae and M. genitalium complicates treatment strategies.
- Sensitivity testing is crucial for N. gonorrhoeae alongside NAATs due to resistance.
