摘要 目的研究柯萨奇B病毒感染对ICR小鼠心肌组织亲嗜性及损害作用,探讨病毒感染与心肌病变之间的关系。方法ICR小鼠130只随机分为感染组(120只)和对照组(10只),感染组再分为CVB3组(60只)和CVB4组(60只)。CVB3组每只腹腔注射4×100 TCID50 CVB3/MKP 0.2ml,CVB4组每只腹腔注射4×100TCIDSO CVB4/jlu06 0.2ml,对照组每只腹腔注射PBS0.2ml。分别在感染后1、4、8、15、27和60 d处死小鼠,无菌取心肌组织,收集血液分离血清,用于病毒滴度的测定及病理学分析。结果两株病毒均在小鼠心肌组织中有较高滴度增殖,并导致了小鼠心肌组织不同程度的损害。结论CVB3/MKP株具有较强的心肌亲嗜性,可引起ICR小鼠心肌组织的严重损伤,该株病毒感染可能与心肌炎的发生密切相关。
