Концепция 3R, разработанная в прошлом столетии поощряет разработку альтернативных тест-систем. Среди прочих альтернативных тест-систем особое место занимает личинка большой восковой моли. Использование личинок большой восковой моли (Galleria melonella) в качестве тест-системы для определения вирулентных свойств микроорганизмов является перспективным направлением и создает возможность удешевления исследований. Однако, не во всех экспериментах исследователи могли зарегистрировать одинаковые полулетальные дозы для выбранных штаммов при сравнении тест-системы Galleria melonella и млекопитающих. Ранее было проведено исследование, где среди прочего определили полулетальные дозы некоторых штаммов при использовании тест-системы Galleria melonella. Целью данного исследования было сравнить полулетальные дозы выбранных штаммов при введении их G. mellonella и мышам. Для проведения эксперимента животным внутрибрюшинно вводили суспензии эталонных штаммов Escherichia coli ATCC 25922 (ВКПМ В – 8076), Staphylococcus aureus ATCC 29213, Streptococcus pneumoniaе ATCC 6303 и клинических изолятов Escherichia coli ENV 194, Staphylococcus aureus SA 0077 (MRSA), Streptococcus pneumoniaе 1068 19 А. После заражения за животными наблюдали ежедневно на протяжении всего эксперимента. Во время ежедневного клинического наблюдения визуально отмечали (при наличии) клинические признаки, свидетельствующие о развитии инфекционного процесса, а также регистрировали массу тела. После определения LD50 результаты были сопоставлены с полученными данными в эксперименте с личинками большой восковой моли. В результате сравнения полулетальных доз выбранных штаммов можно сделать вывод об отсутствии четкой корреляции между данными, полученными в двух экспериментах.</p></abstract><trans-abstract xml:lang="en"><p>To date, conducting experiments involving animals is difficult due to the high cost, the complexity of reproducibility, as well as the ethical standards of modern society. The 3R concept developed in the last century encourages the development of alternative test systems. Among other alternative test systems, the wax moth larva occupies a special place. The use of larvae of the great wax moth (Galleria melonella) as a test system for determining the virulent properties of microorganisms is a promising direction and makes it possible to reduce the cost of research. However, not in all experiments, researchers could register the same semilethal doses for selected strains when comparing the Galleria melonella test system and mammals. Previously, a study was conducted, where, among other things, the semilethal doses of some strains were determined using the Galleria melonella test system. The aim of this study was to compare the semilethal doses of selected strains when administered to G. mellonella and mice. For the experiment, the animals were injected intraperitoneally with suspensions of reference strains of Escherichia coli ATCC 25922 (VKPM B - 8076), Staphylococcus aureus ATCC 29213, Streptococcus pneumoniae ATCC 6303 and clinical isolates of Escherichia coli ENV 194, Staphylococcus aureus SA 0077 (MRSA), Streptococcus pneumoniae 1068 19 A After infection, the animals were observed daily throughout the experiment. During daily clinical observation, visually noted (if any) clinical signs indicating the development of an infectious process, and also recorded body weight. After determining the LD50, the results were compared with the data obtained in the experiment with the larvae of the great wax moth. As a result of comparing the semi-lethal doses of the selected strains, it can be concluded that there is no clear correlation between the data obtained in the two experiments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирулентность</kwd><kwd>LD50</kwd><kwd>Galleria mellonella</kwd><kwd>мышь линии ICR CD1</kwd><kwd>доклинические исследования</kwd><kwd>концепция 3R</kwd></kwd-group><kwd-group xml:lang="en"><kwd>virulence</kwd><kwd>LD50</kwd><kwd>Galleria mellonella</kwd><kwd>ICR CD1 mouse</kwd><kwd>preclinical studies</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">MacArthur Clark, Judy. “The 3Rs in research: a contemporary approach to replacement, reduction and refinement.” The British journal of nutrition vol. 120,s1 (2018): S1-S7</mixed-citation><mixed-citation xml:lang="en">MacArthur Clark, Judy. “The 3Rs in research: a contemporary approach to replacement, reduction and refinement.” The British journal of nutrition vol. 120,s1 (2018): S1-S7</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Макарова М.Н. , Матичин А.А., Матичина А.А., Макаров В.Г.
