TL;DR: Four genes of Chlamydia psittaci strain guinea pig inclusion conjunctivitis, whose predicted products are highly homologous to structural and regulatory components of a contact‐dependent or type III secretion apparatus, were isolated and the possible role of this pathway in chlamydial pathogenesis is discussed.

TL;DR: A multi locus sequence typing (MLST) scheme to understand the population genetic structure and diversity of these species and to evaluate the association between genotype and disease shows that C. trachomatis and C. pneumoniae are highly uniform, which supports the taxonomy of the order of Chlamydiales.

TL;DR: The population structure of Chlamydia was assesed using multi-locus sequence typing to report for the first time an association between C. psittaci genotypes with host species and host species jumps.

TL;DR: The data do not support a role for C. psittaci in the pathogenesis of ocular adnexal lymphomas in patients from the Netherlands and no evidence for the presence of C. Psittaci DNA in any of the tumor samples studied.

TL;DR: In this article, the authors evaluated whether detection of leukocytospermia in a routine semen analysis is of diagnostic value in selecting men with an "actual" microbial infection and assessed the association between leukocyte-salmania and a history of bacterial and viral infections.
