Moonlighting in Rickettsiales: Expanding Virulence Landscape [PDF]
Tropical Medicine and Infectious Disease, 2022 The order Rickettsiales includes species that cause a range of human diseases such as human granulocytic anaplasmosis (Anaplasma phagocytophilum), human monocytic ehrlichiosis (Ehrlichia chaffeensis), scrub typhus (Orientia tsutsugamushi), epidemic ...

Type 1 secretion system and effectors in Rickettsiales
Frontiers in Cellular and Infection Microbiology, 2023 Obligate intracellular bacteria in the order Rickettsiales are transmitted by arthropod vectors and cause life-threatening infections in humans and animals. While both type 1 and type 4 secretion systems (T1SS and T4SS) have been identified in this group,

OVERVIEW OF TICK-ASSOCIATED RICKETTSIALES BACTERIA IN JAPAN
Acta Biomedica Scientifica, 2012 Rickettsiales bacteria are obligatory intracellular parasites in vertebrates and/or invertebrates, and some cause severe febrile illness in humans as well as livestock.

The evolutionary origin of host association in the Rickettsiales [PDF]
Nature Microbiology, 2022 AbstractThe evolution of obligate host-association of bacterial symbionts and pathogens remains poorly understood. The Rickettsiales are an alphaproteobacterial order of obligate endosymbionts and parasites that infect a wide variety of eukaryotic hosts, including humans, livestock, insects and protists.
