100道选择题,带详解.

1、干扰素抗病毒作用的特点是A.有种属特异性和病毒特异性B.无种属特异性，无病毒特异性C.无种属特异性，有病毒特异性D.有种属特异性，无病毒特异性E.只有病毒特异性正确答案：D答案解析：干扰素是由病毒或干扰素诱生剂刺激人或动物细胞产生的一种糖蛋白，具有抗病毒、抗肿瘤和免疫作用。

干扰素是非特异天然免疫的组成部分，不同病毒均可刺激细胞产生干扰素。

干扰素作用于邻近细胞，使之合成一些抗病毒蛋白，从而抑制病毒在这些细胞中复制。

因此，干扰素作用具有种属特异性，但与病毒种类无关。

2、病毒感染的早期快速诊断经常检测的特A.IgMB.IgGC.sIgAD.IgAE.IgE正确答案：A答案解析：IgG出现时间晚，但持续时间长，只有检测发病早期和恢复期双份血清，且恢复期效价较早期4倍增高才有意义，不能用于快速诊断。

但是，IgM产生时间早，持续时间短，检测到高水平特异性IgM，提示近期有该病原感染发生。

3、革兰阳性菌和革兰阴性菌细胞壁共有的成分是A.肽聚糖B.脂蛋白C.外膜D.磷壁酸E.脂多糖正确答案：A答案解析：细胞壁位于菌细胞的最外层，包绕在细胞膜的周围，革兰阳性菌和革兰阴性菌细胞壁的共有组分为肽聚糖。

肽聚糖是细菌细胞壁中的主要组分，为原核细胞所特有。

革兰阳性菌的肽聚糖由聚糖骨架、四肽侧链和五肽交联桥三部分组成，革兰阴性菌的肽聚糖仅由聚糖骨架和四肽侧链两部分组成。

4、甲型溶血性链球菌常引起A.化脓性脑膜炎B.龋齿和心内膜炎C.流产D.中耳炎E.化脓性腹膜炎正确答案：B答案解析：甲型溶血性链球菌亦称草绿色溶血性链球菌。

镜下常呈短链状或成双排列。

血琼脂平板上形成α溶血环。

对人类有致病作用的有轻型链球菌、变异链球菌、唾液链球菌等5个种。

龋齿是一种常见病，与变异链球菌关系密切。

变异链球菌可分解蔗糖产生高分子量、黏性很大的不溶性物质，如葡聚糖或果聚糖，将口腔中众多的菌群黏附于牙齿表面形成菌斑。

其中乳杆菌进一步发酵多种糖类产生大5、与肺炎链球菌抗吞噬、致病性最相关的物质是A.荚膜B.溶血素C.神经氨酸酶D.自溶酶E.胆汁溶菌酶正确答案：A答案解析：荚膜是肺炎链球菌主要的致病因素。
