As already reported in Chapter 1, there has lately been a renewed interest in a group of chlamydial organisms called TWAR agents or TWAR chlamydiae (Saikku et al., 1985, 1986b; Grayston et al., 1986a,b; Kuo et al., 1986a,b). The first TWAR organisms, i.e., TW-183 and IOL-207, were isolated during the late 1960s. In 1972, these U.S. and English chlamydial isolates were found to be antigenically similar in micro-IF tests (Dwyer et al., 1972).
