В этой связи своевременная и точная лабораторная диагностика имеет решающее значение. В статье проведена сравнительная оценка диагностической значимости серологических и молекулярных методов для раннего выявления бруцеллеза и установления скрытых форм инфекции. В период 2019-2021 гг. было исследовано 3208 образцов крови с применением реакций Хеддельсона, Райта, Розе-Бенгал теста, иммуноферментный анализ (ИФА IgG, IgM), а также полимеразная цепная реакция (ПЦР) (n=89, образцы с отрицательной реакцией Райта). Статистическая значимость результатов рассчитывалась с использованием критерия χ2 . Различия признавались статистически значимыми при p&lt;0,05. Классические серологические методы показали высокую диагностическую ценность при вновь выявленных случаях. ИФА выявил позитивные результаты лишь в 17,3% новых случаев. ПЦР позволила дополнительно идентифицировать ДНК Brucella spp. в 14,6% серонегативных образцов. Обоснована необходимость комплексного применения серологических и молекулярных методов.</p></abstract><trans-abstract xml:lang="en"><p>Brucellosis remains an actual issue in Azerbaijan, where an average of 550 new cases are registered each year. So, timely and accurate laboratory diagnosis is very important. The aim: comparatively evaluation of the diagnostic value of serological and molecular methods for the early detection and identification of latent forms of infection. During 2019-2021, a total of 3,208 blood samples were analyzed using the Heddelson, Wright (WR), Rose-Bengal tests, ELISA (IgG, IgM), and PCR (n=89, samples with negative WR). Statistical significance was calculated using the χ² test; differences were considered statistically significant at p&lt;0.05. Classical serological methods demonstrated high diagnostic value in newly diagnosed cases. Only in 17.3% of them detected by ELISA. PCR enabled the additional identification of Brucella spp. DNA in 14.6% of seronegative samples. The necessity of combined use of serological and molecular methods in brucellosis diagnostics has been substantiated. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>бруцеллез</kwd><kwd>диагностическая значимость</kwd><kwd>серологические тесты</kwd><kwd>ИФА</kwd><kwd>ПЦР</kwd></kwd-group><kwd-group xml:lang="en"><kwd>brucellosis</kwd><kwd>diagnostic value</kwd><kwd>serological test</kwd><kwd>ELISA</kwd><kwd>PCR</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Liu Z., Gao L., Wang M., Yuan M., Li Z.
