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,
