肺炎链球菌是一种挑剔的专性寄生虫，寄生在人类身上，偶尔也寄生在其他哺乳动物身上。它的营养需求很复杂，在很大程度上类似于其宿主（Tomasz，1964）。它的生态位是鼻咽；而且，当它定位于该区域时，它与它所居住的主体享有共生关系。只有在延伸到呼吸道的其他区域或穿透鼻咽粘膜通过颈部淋巴管到达体循环后，它才会引起疾病，最终可能对宿主和寄生虫都造成损害。这篇简短综述的目的是探讨影响人与肺炎球菌之间关系的一些因素。
Streptococcus pneumoniae is a fastidious obligate parasite, colonizing man and, occasionally, other mammals. Its nutritional requirements are complex, resembling to a large degree those of its hosts (Tomasz, 1964). Its ecological niche is the nasopharynx; and, when localized to that area, it enjoys a commensal relationship with the subject it inhabits. Only after extending to other areas of the respiratory tract or after penetration of the nasopharyngeal mucosa to reach the systemic circulation via the cervical lymphatics does it give rise to disease which may ultimately work to the detriment of both host and parasite. It is the purpose of this brief review to examine some of the factors which influence the relationships between man and the pneumococcus.
