Regrettably, this introduction does not mention the increasingly recognized role of urogenital chlamydial infections in miscarriage and infections caused by other members of the Chlamydiales order, such as C.
The novel Chlamydiales forms a distinct branch in the well-supported monophyletic clade with the genera Chlamydia and Candidatus Clavochlamydia salmonicola (family Chlamydiaceae) (Figure).
5%) of the 83 fetal samples tested were Chlamydiales positive.
Figure 2 shows a neighbor-joining dendogram demonstrating the relationships of the novel bat bacterial isolate to other members the Chlamydiales.
Criblamydia sequanensis, a new intracellular Chlamydiales isolated from Seine river water using amoebal co-culture.
Because cross-reactivity between members of the order Chlamydiales was proportional to the relatedness between each species (9), the strong cross-reactivity between KNic and Pr.
Waddlia chondrophila, another Chlamydiales, is a new abortigenic agent in bovines (5,6).
Since elementary and reticulate bodies are similar in both Chlamydiaceae and Parachlamydiaceae (6), Chlamydiales cannot be identified in a specimen solely by electron microscopy.
Additional arguments in favor of a pathogenic role of the Parachlamydiaceae are that Chlamydia pneumoniae, a well-recognized agent of pneumonia, was shown to infect free-living amoebae (19) and that another member of the Chlamydiales, Simkania negevensis (49,50), which has 88% homology with P.
