Summary

大鼠实验性心内膜炎模型由于耐甲氧西林<em> S金黄色葡萄球菌</em>。

Abstract

血管内感染,包括感染性心内膜炎,危及生命的传染病综合征1-3。 金黄色葡萄球菌是最常见的世界性不可接受的高发病率和死亡率甚至与适当的抗菌剂治疗4-6综合征的原因。在感染的增加,由于耐甲氧西林S.金黄色葡萄球菌 (MRSA),万古霉素的临床治疗失败和利奈唑胺和达托霉素抵抗日益严重的问题的高利率有此类感染患者都进一步复杂化的管理,并导致高的医疗费用7,8。此外,应强调用抗生素治疗效果的最近期的研究已根据临床的设置,因此很可能被主机从病人到门诊不同因素的影响。因此,有关的腔内感染的动物模型,在宿主因素是相似的,从动物到动物更探讨微生物的发病机制,以及新型抗菌药物的疗效的关键。在大鼠感染性心内膜炎是一种行之有效的实验动物模型,接近人天然瓣膜心内膜炎。该模型已被用于研究,尤其是金黄色葡萄球菌致病因素的作用,并为金黄色葡萄球菌感染性心内膜炎的抗生素治疗方案的疗效。在这份报告中,我们描述的实验性心内膜炎模型,由于MRSA的,可以用来研究细菌致病和抗生素治疗。

Protocol

1。 MRSA菌株感染的准备接种MRSA的文化loopful从股票管在-80°C到胰酶大豆琼脂(TSA)板的羊血(见特定的试剂和设备表),并于37℃过夜。 检查的文化上的血琼脂平板上(类似殖民地的表型),以确保有是没有污染的纯度。 从绵羊血TSA的板接一个殖民地和SNAP-皑皑管15毫升到5毫升胰酪胨大豆肉汤(TSB)在接种殖民地。 在37°C间在200 rpm摇过夜。 2。…

Discussion

大鼠感染性心内膜炎是一个重要和良好的特点的动物模型,为在体内研究中的发病机制和抗菌药物在治疗细菌感染9-11。此外,在大鼠感染性心内膜炎模型代表一种急性,亚急性感染的复合材料,并密切模仿人类的​​对口和人天然瓣膜心内膜炎。此外,在住宅导管的陪同下,它代表一个典型的生物膜相关感染常见和棘手的问题,在12个临床的设置。大鼠感染性心内膜炎模型…
