Assessing the Need for Routine Screening for Mycoplasma genitalium in the Low-risk Female Population: A Prevalence and Co-infection Study on Women from Croatia.

BACKGROUND

There is an ongoing debate regarding possible cost and benefits, but also harm of universal screening for the emerging sexually transmitted pathogen Mycoplasma genitalium.

METHODS

From the initial pool of 8665 samples that were tested, a subset of Chlamydia trachomatis-positive and randomly selected C. trachomatis-negative cervical swabs were further interrogated for M. genitalium by real-time polymerase chain reaction, using a 224 bp long fragment of the glyceraldehyde-3-phosphate dehydrogenase gene.

RESULTS

M. genitalium was detected in 4.8% of C. trachomatis-positive samples and none of C. trachomatis-negative samples. Accordingly, a significant association was shown between M. genitalium and C. trachomatis (P < 0.01), but also between M. genitalium and Mycoplasma hominis infection (P < 0.01).

CONCLUSIONS

Based on the results, routine screening is recommended only for women with one or more identified risk factors. Moreover, younger age does not represent an appropriate inclusion/exclusion criterion for M. genitalium testing in the low-risk female population.
