In 1986 Grayston and coworkers termed TWAR (or Taiwan Acute Respiratory) a new strain of Chlamydia which has still not received an exact taxonomic classification. In fact, whereas initially the TWAR strain was classified as C. psittaci because of its oval-shaped, glycogen free, dense inclusions, recent studies on the immunological analysis, DNA analysis and ultrastructural morphology, would seem to indicate that TWAR is a new Chlamydial species, whose proposed name as C. pneumonia. TWAR is mainly responsible for respiratory syndrome varying in gravity from a slight form to pneumonia, and is liable to give rise to epidemic forms; in addition, more recently, certain Authors have postulated its involvement in the pathogenesis of ischemic cardiopathy.
1986年，格雷斯顿及其同事将TWAR（或台湾急性呼吸道病原体）称为一种新型衣原体菌株，至今仍未得到确切的分类学归类。事实上，最初TWAR菌株因其椭圆形、无糖原、致密的包涵体而被归类为鹦鹉热衣原体，但最近关于免疫分析、DNA分析和超微结构形态的研究似乎表明，TWAR是一种新的衣原体物种，其提议的名称为肺炎衣原体。TWAR主要引起从轻微形式到肺炎不等的呼吸道综合征，且易于引发流行形式；此外，最近有一些作者推测它与缺血性心脏病的发病机制有关。
