链球菌属
链球菌(学名:Streptococcus)是一类球形的革兰氏阳性细菌,属于厚壁菌门的一个属。这些细菌细胞分裂时总是沿一个轴,所以通常成对或者链状的。因为这些特征,他们被称作“链球菌”,区别于可以沿多个轴分裂而形成一团细胞的“葡萄球菌”(Staphylococcus)。链球菌属包含了很多个种,其中多数是在人和动物表皮,呼吸道等处的共生菌(commensal flora),也有对人类有益的菌种如嗜热链球菌(Streptococcus thermophilus),但其中也有相当数量的致病菌种。

种类划分
编辑一般以兰斯菲尔德分类法(Lancefield classification)和溶血类型划分。例如产脓链球菌(Streptococcus pyogenes)为兰斯菲尔德一型(Group A)并为β溶血类型(β-haemolytic)。
肺炎链球菌(Streptococcus pneumoniae)没有兰斯菲尔德抗原,但是可以根据它是从呼吸道中提取,显微镜下为双球菌状(diplococcus),α溶血,菌落呈湿润状(有荚膜生成),中间有凹陷(draughtsman shape,因为有autolysin产生),以确定。

传染途径
编辑链球菌通常寄生在口腔、皮肤、肠道和上呼吸道,因为其它共生菌的竞争和免疫系统它们一般不会造成疾病,所以被认为是人的正常共生菌落的一部分。但是当某些特定的菌株进入人体,并在特定组织或器官建立起感染时,便会引发疾病。链球菌的种类很多,可以感染人体的多种部位,导致多种不同疾病。
链球菌会通过以下特定的方式传播:
- 物理接触。
- 通过被链球菌污染的食物及其盛放器具。
- 通过咳嗽,喷嚏等反应从呼吸道中带出细菌。
致病菌种
编辑链球菌属(Streptococcus)中,以兰斯菲尔德分类法划分可以导致疾病的种有:
一型链球菌
编辑一型链球菌(Group A Streptococci),如产脓链球菌(Streptococcus pyogenes) 造成一型链球菌感染(Group A streptococcal infection)。
产脓链球菌会感染成年人,导致发烧,喉咙痛(链球菌性咽炎),颈部淋巴肿大。当被感染时,小孩可能会有喉咙痛、皮疹、腹部绞痛等症状,医生可以从咽喉提取样本进行培养和生化测试以确诊。值得注意的是产脓链球菌和很多其它链球菌有M蛋白抗原(M-protein antigen),这种抗原与心脏肌肉和关节处组织的抗原很相像,长时间的链球菌感染会产生自免疫反应, 增加类风湿性关节炎和风湿性心肌炎的危险。
二型链球菌
编辑二型链球菌(Group B Streptococci),也称为GBS,如Streptococcus agalactiae,会导致新生儿和老年人的脑膜炎,有时也会导致全身性的细菌性败血症。
链球菌通常也会寄生在女性的生殖道内,产生酸性环境,抑制其它细菌,但是有些二型链球菌会感染生殖道,增加羊膜过早破裂的危险,使胎儿流产。
美国疾病控制预防中心(Centers for Disease Control and Prevention(CDC)有专门的对GBS的介绍:Preventing Group B Strep Disease (页面存档备份,存于互联网档案馆)
四型链球菌
编辑四型链球菌(Group D Streptococci):S. durans、S. avium、牛链球菌(S. bovis)
肺炎链球菌(Streptococcus pneumoniae)在很少的情况下(如免疫力降低)从上呼吸道进入下呼吸道再进入肺部,产生肺炎链球菌溶血素(pneumolysin),在肺部建立感染,因免疫反应而使肺部机能失常,导致肺炎。
草绿色链球菌
编辑草绿色链球菌(Streptococcus viridans)可以导致心内膜炎和口腔感染。
