Заражение собак происходит при контакте с мочой носителей или через заражённую окружающую среду, где лептоспиры сохраняются длительное время [<xref ref-type="bibr" rid="cit1">1</xref>]. Проведен серологический мониторинг по выявлению доминирующей серогруппы лептоспир у собак на территории Санкт-Петербурга. Установлено, что в период с 2022 по 2024 гг. преобладающей оказалась серогруппа Icterohaemorrhagiae (463 случая), что подтверждается высокими титрами антител до 1:1600. При анализе антител к серогруппам в ассоциации с доминирующей серогруппой наиболее часто встречались Cynopteri (52 образца) и Pomona (50 образцов). Наименьшее количество находок (по 3 образца) отмечено для серогрупп Bataviae, Tarassovi и Sejroe. Использование вакцины против лептоспироза собак обеспечивает защиту против некоторых серогрупп, а именно Icterohaemorrhagiae, Canicola, и Grippotyphosa. Однако на территории РФ отсутствуют отечественные вакцины, которые включают в свой состав следующие серогруппы: Cynopteri, Pomona, Pyrogenes, Autumnalis, Ballum, Hebdomadis, Javanica, Australis, Bataviae, Tarassovi и Sejroe, поэтому лептоспироз следует включать в дифференциальную диагностику у вакцинированных собак, демонстрирующих клинические признаки инфекционного заболевания. Также актуальной задачей является поиск свежих вакцинных штаммов лептоспир, так как используемые в настоящее время штаммы являются достаточно устаревшими, что могло привести к частичной потере их иммуногенных свойств. Полученные данные требуют усиления профилактических мероприятий, направленных на улучшение эпизоотической ситуации по лептоспирозу собак в Санкт-Петербурге. Для чего большое значение имеет разработка и применение поливалентных вакцин, содержащих антигены наиболее распространённых в регионе серогрупп лептоспир, а также внедрение системы регулярного серологического мониторинга среди популяции собак города.</p></abstract><trans-abstract xml:lang="en"><p>Leptospirosis is a zoonotic disease that occurs predominantly in dogs in megacities, which makes the control and prevention of this disease particularly relevant for protecting the health of pets and the general population. Dogs become infected through contact with the urine of carriers or through contaminated environments where leptospires persist for long periods [<xref ref-type="bibr" rid="cit1">1</xref>]. Serological monitoring was conducted to identify the dominant leptospire serogroup in dogs in St. Petersburg. It was found that in the period from 2022 to 2024, the predominant serogroup was Icterohaemorrhagiae (463 cases), which is confirmed by high antibody titers up to 1:1600. When analyzing antibodies to serogroups in association with the dominant serogroup, Cynopteri (52 samples) and Pomona (50 samples) were the most common. The lowest number of findings (3 samples each) was recorded for the serogroups Bataviae, Tarassovi, and Sejroe. The use of a dog leptospirosis vaccine provides protection against certain serogroups, namely Icterohaemorrhagiae, Canicola, and Grippotyphosa. However, there are no domestic vaccines in the Russian Federation that include the following serogroups: Cynopteri, Pomona, Pyrogenes, Autumnalis, Ballum, Hebdomadis, Javanica, Australis, Bataviae, Tarassovi, and Sejroe. Therefore, leptospirosis should be included in the differential diagnosis of vaccinated dogs showing clinical signs of an infectious disease. Another important task is to find fresh vaccine strains of leptospires, as the currently used strains are quite outdated, which may have led to a partial loss of their immunogenic properties. The obtained data require strengthening of preventive measures aimed at improving the epizootic situation of leptospirosis in dogs in St. Petersburg. The development and use of polyvalent vaccines containing antigens of the most common leptospire serogroups in the region, as well as the implementation of a regular serological monitoring system among the city's dog population, are of great importance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лептоспироз собак</kwd><kwd>Санкт-Петербург</kwd><kwd>специфическая профилактика</kwd><kwd>реакция микроагглютинации</kwd><kwd>Leptospira</kwd></kwd-group><kwd-group xml:lang="en"><kwd>canine leptospirosis</kwd><kwd>Saint Petersburg</kwd><kwd>specific prevention</kwd><kwd>microagglutination test</kwd><kwd>Leptospira</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">Sykes JE, Francey T, Schuller S, Stoddard RA, Cowgill LD, Moore GE.
