В связи с этим очень важным является правильная лабораторная идентификация фенотипа MRSA, основанная на использовании маркёрного антибиотика - цефокситина, чувствительность которого выше, чем оксациллина. Тенденцией последних лет является появление штаммов со сниженной чувствительностью к препаратам «последней линии защиты» от MRSA: ванкомицину и даптомицину. В России не изучена чувствительность MRSA к этим препаратам, и отсутствуют данные о распространении VISA (vancomycin-intermediate Staphylococcus aureus) и hVISA (heteroVISA) фенотипов. В настоящей работе представлены результаты оценки чувствительности 316 изолятов MRSA, собранных в нескольких регионах страны к оксациллину, цефокситину, ванкомицину и даптомицину. Так, установлено, что диапазон минимальной подавляющей концентрации (МПК) оксациллина лежит в очень широких пределах: 0,5-512 мкг/мл, при этом 2,2±1% штаммов фенотипически проявляют чувствительность к оксациллину, несмотря на наличие гена mecA. Напротив, к цефокситину эти изоляты MRSA проявляли выраженный уровень устойчивости, МПК&gt;16 мкг/мл. По результатам серийных микроразведений выявлено, что 30,7±7% штаммов имеют критический уровень чувствительности с МПК 2 мкг/мл к ванкомицину, а при использовании Е-тестов выявлено 1,3+1% штаммов с МПК, равным 2-4 мкг/мл. MRSA проявляли высокую степень чувствительности к даптомицину, однако 2,8±1% штаммов характеризовались высокими значениями МПК (2 мкг/мл). Более того, в работе отмечено перекрёстное снижение чувствительности к ванкомицину и даптомицину.</p></abstract><trans-abstract xml:lang="en"><p>Prevalence and therapy of infections due to MRSA remain one of the most serious problems in the world. Therefore, correct laboratory identification of the MRSA phenotype based on the use of the marker antibiotic cefoxitine, as a more susceptibile one vs. oxacillin, is of great importance. There is lately being observed a tendency towards emergence of strains with lower susceptibility to the last reserve drugs protecting from MRSA, i. e. vancomycin amd daptomycin. Susceptibility of MSRA to these drugs was not investigated in Russia and there are no data on the prevalence of the VISA and hVISA phenotypes. The results of our study on estimation of susceptibility of 316 MRSA isolates from several regions of Russia to oxacillin, cefoxitine, vancomycin and daptomycin are presented herein. It was shown that the ranges of the oxacillin MIC were extremely wide, i. e. 0.5 to 512 mcg/ml, while 2.2±1% of the isolates was susceptible by the phenotype to oxacillin, in spite of the mecA gene presence. As for cefoxitine, the MRSA isolates were rather resistant to it at the MIC &gt; 16 mcg/ml. The tests with serial microdilutions revealed that 30.7±7% of the isolates had a critical level of susceptibility to vancomycin at the MIC 2 mcg/ml. The E-tests revealed 1.3±1% of the isolates which were susceptible at the MIC 2-4 mcg/ml. The MRSA isolates were highly susceptible to daptomycin, while high levels of the MIC (2 mcg/ml) were characteristic of 2.8±1% of the isolates. Cross reduction of the susceptibility to vancomycin and daptomycin was observed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метициллинорезистентные стафилококки (MRSA)</kwd><kwd>оксацимин</kwd><kwd>цефокситин</kwd><kwd>ванкомицин</kwd><kwd>даптомицин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>methicillin resistant staphylococci (MRSA)</kwd><kwd>oxacillin</kwd><kwd>cefoxitine</kwd><kwd>vancomycin</kwd><kwd>daptomycin</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">Chambers H.F.
