Его клинические проявления могут быть острыми или хроническими, локальными или генерализованными. У человека прототекоз является редким и при тяжёлом течении – высоколетальным заболеванием. Прототекоз проявляется в виде трех синдромов: инфекции кожи или мягких тканей, бурсита локтевого отростка или диссеминированной инфекции, в том числе с поражением оболочек и вещества мозга (менингоэнцефалиты).</p><p>Диагноз ставят на основании гистологического исследования биопсийного материала и микробиологического исследования спиномозговой жидкости и пораженных тканей. В работе рассмотрен клинический случай менингоэнцефалита, вызванный возбудителем Prototheca spp. Проанализированы актуальные литературные источники, история болезни, данные лабораторных обследований пациента.</p><p>Накопление информации об этом заболевании, его эпидемиологических и клинических особенностях, возможностях идентификации будет способствовать верификации диагноза, снижению летальных исходов, в том числе у пациентов с хроническими заболеваниями и иммунодефицитными состояниями.</p></abstract><trans-abstract xml:lang="en"><p>Protothecosis is a rare infectious disease caused by non-photosynthetic algae belonging to the genus Prototheca. Its clinical manifestations may be acute or chronic, localized or generalized. In humans, protothecosis is a rare and, in severe cases, highly lethal disease. Protothecosis manifests as three syndromes: skin or soft tissue infection, ulnar bursitis, or disseminated infection, including lesions of the brain membranes and substance (meningoencephalitis).</p><p>The diagnosis is made on the basis of histologic examination of biopsy material and microbiologic examination of cerebrospinal fluid and affected tissues. In this paper we consider a clinical case of meningoencephalitis caused by the pathogen Prototheca spp. Current literature sources, case history, and data of laboratory examinations of the patient were analyzed.</p><p>The accumulation of information about this disease, its epidemiologic and clinical features, and identification possibilities will contribute to the verification of the diagnosis, reduction of lethal outcomes, including in patients with chronic diseases and immunodeficiency states.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прототекоз</kwd><kwd>водоросль Prototheca spp.</kwd><kwd>клинический случай</kwd><kwd>менингоэнцефалит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>protothecosis</kwd><kwd>algae Prototheca spp.</kwd><kwd>clinical case</kwd><kwd>meningoencephalitis</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">Shave C.D., Millyard L., May R.C.
