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,

Extensive diversity of Rickettsiales bacteria in two species of ticks from China and the evolution of the Rickettsiales [PDF]
BMC Evolutionary Biology, 2014 Les bactéries de l'ordre des Rickettsiales (Alphaproteobacteria) sont des parasites intracellulaires obligatoires qui infectent les espèces de pratiquement toutes les grandes lignées eucaryotes. Plusieurs genres rickettsiaux abritent des espèces qui sont d'importants agents pathogènes émergents et ré-émergents de l'homme.
