鏈球菌屬
鏈球菌(學名:Streptococcus)是一類球形的革蘭氏陽性細菌,屬於厚壁菌門的一個屬。這些細菌細胞分裂時總是沿一個軸,所以通常成對或者鏈狀的。因爲這些特徵,他們被稱作「鏈球菌」,區別於可以沿多個軸分裂而形成一團細胞的「葡萄球菌」(Staphylococcus)。鏈球菌屬包含了很多個種,其中多數是在人和動物表皮,呼吸道等處的共生菌(commensal flora),也有對人類有益的菌種如嗜熱鏈球菌(Streptococcus thermophilus),但其中也有相當數量的致病菌種。

種類劃分
一般以蘭斯菲爾德分類法(Lancefield classification)和溶血類型劃分。例如產膿鏈球菌(Streptococcus pyogenes)為蘭斯菲爾德一型(Group A)並為β溶血類型(β-haemolytic)。
肺炎鏈球菌(Streptococcus pneumoniae)沒有蘭斯菲爾德抗原,但是可以根據它是從呼吸道中提取,顯微鏡下為雙球菌狀(diplococcus),α溶血,菌落呈濕潤狀(有莢膜生成),中間有凹陷(draughtsman shape,因為有autolysin產生),以確定。

傳染途徑
鏈球菌通常寄生在口腔、皮膚、腸道和上呼吸道,因為其它共生菌的競爭和免疫系統它們一般不會造成疾病,所以被認為是人的正常共生菌落的一部分。但是當某些特定的菌株進入人體,並在特定組織或器官建立起感染時,便會引發疾病。鏈球菌的種類很多,可以感染人體的多種部位,導致多種不同疾病。
鏈球菌會通過以下特定的方式傳播:
- 物理接觸。
- 通過被鏈球菌污染的食物及其盛放器具。
- 通過咳嗽,噴嚏等反應從呼吸道中帶出細菌。
致病菌種
鏈球菌屬(Streptococcus)中,以蘭斯菲爾德分類法劃分可以導致疾病的種有:
一型鏈球菌
一型鏈球菌(Group A Streptococci),如產膿鏈球菌(Streptococcus pyogenes) 造成一型鏈球菌感染(Group A streptococcal infection)。
產膿鏈球菌會感染成年人,導致發燒,喉嚨痛(鏈球菌性咽炎),頸部淋巴腫大。當被感染時,小孩可能會有喉嚨痛、皮疹、腹部絞痛等症狀,醫生可以從咽喉提取樣本進行培養和生化測試以確診。值得注意的是產膿鏈球菌和很多其它鏈球菌有M蛋白抗原(M-protein antigen),這種抗原與心臟肌肉和關節處組織的抗原很相像,長時間的鏈球菌感染會產生自免疫反應, 增加類風濕性關節炎和風濕性心肌炎的危險。
二型鏈球菌
二型鏈球菌(Group B Streptococci),也稱為GBS,如Streptococcus agalactiae,會導致新生兒和老年人的腦膜炎,有時也會導致全身性的細菌性敗血症。
鏈球菌通常也會寄生在女性的生殖道內,產生酸性環境,抑制其它細菌,但是有些二型鏈球菌會感染生殖道,增加羊膜過早破裂的危險,使胎兒流產。
美國疾病控制預防中心(Centers for Disease Control and Prevention(CDC)有專門的對GBS的介紹:Preventing Group B Strep Disease (頁面存檔備份,存於互聯網檔案館)
四型鏈球菌
四型鏈球菌(Group D Streptococci):S. durans、S. avium、牛鏈球菌(S. bovis)
肺炎鏈球菌(Streptococcus pneumoniae)在很少的情況下(如免疫力降低)從上呼吸道進入下呼吸道再進入肺部,產生肺炎鏈球菌溶血素(pneumolysin),在肺部建立感染,因免疫反應而使肺部機能失常,導致肺炎。
草綠色鏈球菌
草綠色鏈球菌(Streptococcus viridans)可以導致心內膜炎和口腔感染。
