Objective. The purpose of the study was investigation of the clinical specimens obtained from the urogenital tract of couples coping with infertility for the presence of genetic material of wtCT and nvCT. Material and methods. Clinical samples (scrapings from the urethra and cervix) obtained from 25 to 41 years old couples (n = 14) were tested for the presence of identifiable wtCT and nvCT chlamydia DNA by monoplex and duplex PCR, specific antigens C. trachomatis in elementary bodies by using immunofluorescence analysis (IFA), while detection of anti-chlamydia antibodies in sera was determined by immunoenzymatic assay (IEA). Results. The nvCT variant with typical deletion of 377 bp within the orf1 gene that belongs to the genovar e subtype E1 was detected in 100% of couples with infertility. The negative results of DNA testing for wtcT were registered in 87.5% of patients from this group, while one individual (12.5%) was likely coinfected with nvCT and wtCT of E1 and D genovars, respectively. The wtCT strains of genovar E (subtypes E1, E2, E6), g (subtypes G1, G2), F (subtypes F1), and K were identified in control group among patients with UGCI. The study revealed difficulties in detection of nvCT by nucleic acid amplification test (NAAT), IFA, and IEA; data on comparison of the efficacy of these methods are presented. Conclusion. Chronic UGCI in patients with reproductive dysfunctions can be caused by nvCT alone or as result of co-infection with nvCT and wtCT. The negative results in NAAT may not 100% correlate with the absence of UGCI that requires further confirmation in tests allowing detection of all known variants of C. trachomatis.</p></abstract><trans-abstract xml:lang="ru"><p>В развитии бесплодия доминирующую роль отводят инфекциям, передаваемым половым путем (ИППП), среди которых лидирует урогенитальная хламидийная инфекция (УГХИ), вызываемая Chlamydia trachomatis (СТ). Известно два варианта возбудителя, представленных дикими (wtCT) и новыми (nvCT) штаммами СТ с делецией размером 377 bp в участке гена orf1 криптической плазмиды. Цель исследования. Изучение клинического материала, полученного из урогенитального тракта супружеских пар с бесплодием, на наличие генетического материала wtCT и nvCT. Материал и методы. Клинический материал (соскобы из уретры и цервикального канала) супружеских пар (п = 14) в возрасте от 25 лет до 41 года на наличие специфической хламидийной ДНК wtCT и nvCT или специфических антигенов C. trachomatis исследовали моноплексными и дуплексными вариантами ПЦР, элементарных телец хламидий - ПИФ, обнаружение хламидийных антител в образцах сыворотки крови проводили методом ТИФА. Результаты. У 100% супружеских пар с бесплодием был детектирован nvCT с типичной делецией в 377 bp геновара Е1. Отрицательные результаты на наличие ДНК wtCT зарегистрированы у 87,5% пациентов этой группы, у одного пациента (12,5%) - вероятная коинфекция nvCT + wtCT геноваров Е1 + D. В контрольной группе с УГХИ выявлены штаммы только wtCT геноваров Е (субтипов Е1, Е2, Е6), G (субтипов G1, G2), F (субтип F1) и K. Показаны трудности обнаружения nvCT при использовании МАНК, ПИФ и ТИФА, приводятся сведения о сравнительной эффективности методов. Заключение. Хроническая УГХИ у пациентов с нарушением репродуктивной функции может быть вызвана моноинфекцией nvCT или коинфекцией nvCT + wtCT. Отрицательные результаты МАНК не могут в 100% случаев коррелировать с отсутствием УГХИ и требуют дальнейшего подтверждения в тестах, позволяющих выявлять все известные варианты C. trachomatis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>урогенитальная хламидийная инфекция</kwd><kwd>Chlamydia trachomatis</kwd><kwd>новый «шведский» вариант</kwd><kwd>nvCT</kwd><kwd>ПЦР-диагностика</kwd><kwd>бесплодие</kwd><kwd>uro-genital chlamydial infection</kwd><kwd>Chlamydia trachomatis</kwd><kwd>novel Swedish strain</kwd><kwd>nvCT</kwd><kwd>PCR-diagnostics</kwd><kwd>infertility</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Указ Президента РФ № 1351 от 09.10.2007 «Об утверждении Концепции демографической политики Российской Федерации на период до 2025 года».
