Resumen
ESCOBEDO-GUERRA, Marcos R. et al. Multiplex PCR testing for the atypical microorganisms diagnosis sexually transmitted. Perinatol. Reprod. Hum. [online]. 2023, vol.37, n.3, pp.108-114. Epub 01-Mar-2024. ISSN 2524-1710. https://doi.org/10.24875/per.23000024.
Background:
Sexually transmitted infections are a global public health problem. Routine analysis includes microbiological and serological tests for the diagnosis of pathogens. Atypical microorganisms such as Chlamydia trachomatis and mycoplasmas are not determined due to the requirements for their identification. Furthermore, Gardnerella vaginalis is not included despite being associated with bacterial vaginosis.
Objective:
To develop a multiplex PCR to diagnose Chlamydia, mycoplasmas, and Gardnerella.
Method:
Standardization of multiplex PCR tests was carried out using oligonucleotides for the identification of Chlamydia (ompA gene, plasmid orf6), Mycoplasma/Ureaplasma and Gardnerella (rRNA16s genes).
Results:
Multiplex PCR tests were standardized for the microorganisms studied, optimizing the concentrations and conditions of the multiplex reactions. Duplex PCR was obtained for Chlamydia (ompA, orf6), Chlamydia/Gardnerella, and Chlamydia/mycoplasmas, and triplex PCR for Chlamydia/mycoplasmas. Also, a quadruplex for Chlamydia, Mycoplasma/Ureaplasma and Gardnerella. PCR and automatic hybridization verified the results obtained (HybriSpot 12) and in silico analysis.
Conclusion:
Multiplex PCR tests with high sensitivity and specificity were developed to identify C. trachomatis, mycoplasmas, and G. vaginalis.
