Несмотря на статистический учет, который успешно ведется в других странах мира на протяжении уже многих лет, данные о распространении инфекции в Российской Федерации малочисленны, а выборки представлены небольшим количеством животных. Проведено исследование 11 807 образцов крови, собранных на территории г. Москвы и Московской области, на наличие антигена вируса лейкемии кошек и/или антител против возбудителя методами полимеразной цепной реакции, иммуноферментного и иммунохроматографического анализов. Превалентность вирусной лейкемии кошек составила 12,8%, что коррелирует с превалентностью заболевания, выявленной в развивающихся странах, и характеризует высокую степень распространенности инфекции в популяции домашних кошек г. Москвы и Московской области. Наиболее часто вирус лейкемии кошек выявляли у самцов и самок, имеющих свободный доступ на улицу. При проведении диагностических исследований установлены следующие гематологические отклонения: анемия, тромбоцитопения, лимфоцитопения и сдвиг лейкоцитарной формулы влево. Биохимический анализ крови показал повышение уровней общего белка, аспартатаминотрансферазы, щелочной фосфатазы и С-реактивного белка. Полученные данные отражают неспецифичность гематологической и биохимической картины анализа крови, представленной у инфицированных кошек, и диктуют необходимость дальнейшего изучения факторов риска, предрасполагающих кошек к заражению данным вирусным заболеванием. Ветеринарные специалисты должны подозревать заболевание вирусной лейкемией кошек в случае наличия неспецифической клинической картины, а также в случае выявления отклонений от нормы параметров гематологического и биохимического анализа крови животных, имеющих свободный доступ на улицу или имеющих подтвержденный контакт с сородичами.</p></abstract><trans-abstract xml:lang="en"><p>Feline viral leukemia is an infectious disease that is common throughout the world. Despite the statistical records that have been successfully kept in other countries for many years, there is little data on the prevalence of the infection in the Russian Federation, and the samples are represented by a small number of animals. 11,807 blood samples collected in Moscow and the Moscow Oblast were tested for FeLV antigen and antibodies against FeLV by polymerase chain reaction, enzyme immunoassay, and immunochromatographic assay. The prevalence of feline viral leukemia was 12.8%, which correlates with the prevalence of the disease detected in developing countries, and speaks of a high disease prevalence in domestic cats in Moscow and the Moscow Oblast. Most often, feline leukemia virus was detected in free roaming domestic cats. During the diagnostic studies, the following hematological abnormalities were found: anemia, thrombocytopenia, lymphopenia, and a shift of the leukocyte formula to the left. Biochemical blood tests showed the increased levels of total protein, aspartate aminotransferase, alkaline phosphatase, and C-reactive protein. The obtained data demonstrate non-specific hematological and biochemical abnormalities in infected cats, and dictate the need for further study of the risk factors that predispose cats to the infection with this viral disease. Feline viral leukemia should be suspected in case of a non-specific clinical picture, as well as in case of abnormalities in blood biochemical and hematological parameters of free roaming cats or of those which have had a confirmed contact with their conspecifics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Вирусная лейкемия кошек</kwd><kwd>вирусный иммунодефицит кошек</kwd><kwd>иммуносупрессия</kwd><kwd>превалентность</kwd><kwd>анемия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Feline viral leukemia</kwd><kwd>feline viral immunodeficiency</kwd><kwd>immunosuppression</kwd><kwd>prevalence</kwd><kwd>anemia</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">Westman M.
