Abstract
ESCOBEDO-GUERRA, Marcos R et al. Atypical detection of non-human Chlamydia pneumoniae in an endocervical sample. Case Report. Ginecol. obstet. Méx. [online]. 2021, vol.89, n.12, pp.978-984. Epub May 23, 2022. ISSN 0300-9041. https://doi.org/10.24245/gom.v89i12.5837.
BACKGROUND:
Chlamydia trachomatis is one of the leading sexually transmitted microorganisms that is significantly associated with the development of female infertility. The detection of genotypes and new variants ofChlamydia trachomatisallows us to know their prevalence and geographic distribution, identify the appearance of antimicrobial resistance, clinical associations, or sexual behaviors, and develop vaccines. This clinical case reports for the first time endocervical infection by a strain other thanC. trachomatis.
CLINICAL CASE:
A 25-year-old woman with primary infertility of 2 years of evolution due to endocrine-ovarian factor (overweight and subclinical hypothyroidism) and male factor characterized by hypospermia and teratozoospermia. Endocervical microbiological culture detected infection byUreaplasma urealyticumandChlamydiaspp. Identification of theChlamydiastrain by sequencing the 16S rRNA gene reported that it wasChlamydia pneumoniae. The presence of plasmid in this strain ofC. pneumoniaeconfirmed that the endocervical infection was by a non-humanChlamydia pneumoniaestrain.
CONCLUSION:
This clinical case suggests that a non-human strain ofC. pneumoniaecan be sexually transmitted to humans, circulating in the Mexican population, and causing infertility, although the origin and direction of transmission are still unknown.
