Evasion of autophagy mediated by Rickettsia surface protein OmpB is critical for virulence. [PDF]
, 2019 Rickettsia are obligate intracellular bacteria that evade antimicrobial autophagy in the host cell cytosol by unknown mechanisms. Other cytosolic pathogens block different steps of autophagy targeting, including the initial step of polyubiquitin-coat ...

Parasite Immunology, Volume 48, Issue 3, March 2026.ABSTRACT Tick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.). The impact of saliva from these species on murine macrophages remains unclear.
