Scrub typhus and the rickettsial diseases represent some of the oldest recognized vector-
transmitted diseases, fraught with a rich historical aspect, particularly as applied to …

Chlamydia, comprising several human and zoonotic pathogens, is a genus of the conserved
bacterial phylum Chlamydiota. Their obligate intracellular niche serves as a barrier for …

Sequenced genomes of this bacterial order have provided exciting insights into reductive
genome evolution, antigenic variation and host cell manipulation. The 2,127,051-bp …

Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi infection and one
of main causes of febrile illness in the Asia-Pacific region. It has been estimated that one …

Our understanding of free-living bacterial models like Escherichia coli far outpaces that of
obligate intracellular bacteria, which cannot be cultured axenically. All obligate intracellular …

Within the last 15 years, advances in whole genome sequencing (WGS) technologies and
expansions in publicly available chlamydial genomes have dramatically increased our …

Abstract The order Rickettsiales (Alphaproteobacteria) encompasses multiple diverse
lineages of host-associated bacteria, including pathogens, reproductive manipulators, and …

Chlamydiaceae are obligate intracellular bacteria that cause a diversity of severe infections
among humans and livestock on a global scale. Identification of new species since 1989 …

The rickettsial human pathogen Orientia tsutsugamushi (Ot) is an obligate intracellular Gram-
negative bacterium with one of the most highly fragmented and repetitive genomes of any …

Chlamydia psittaci is a zoonotic pathogen that infects birds, humans, and other mammals.
Notably, recent studies suggested the human-to-human transmission of C. psittaci, and this …
