TlyC, a conserved hemolysin in Rickettsia, contributes to spotted fever pathogenesis in mice [PDF]
Microbiology SpectrumRickettsia circulates between mammalian hosts and hematophagous arthropod vectors by exploiting their intracellular environment. With advances in rickettsial genetic tools, recent studies have identified novel molecular mechanisms involved in Rickettsia ...

The Rickettsia conorii Adr1 Interacts with the C-Terminus of Human Vitronectin in a Salt-Sensitive Manner [PDF]
Front Cell Infect Microbiol, 2017 Spotted fever group (SFG) Rickettsia species are inoculated into the mammalian bloodstream by hematophagous arthropods. Once in the bloodstream and during dissemination, the survival of these pathogens is dependent upon the ability of these bacteria to ...

Optimization of heat inactivation protocols for Orientia and Rickettsia species [PDF]
Scientific ReportsHeat treatment, or thermal disinfection, is one of the simplest and most widely used methods for microbial inactivation. Proper heat inactivation protocols are essential to ensure the safe transportation and handling of infectious materials, particularly

Evasion of autophagy mediated by Rickettsia surface protein OmpB is critical for virulence [PDF]
Nature Microbiology, 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 ...

Tick-Borne Rickettsioses in the Iberian Peninsula
Pathogens, 2022 Tick-borne rickettsioses (TBR) are caused by obligate, intracellular bacteria of the spotted-fever group (SFG) of the genus Rickettsia (Order Rickettsiales), transmitted by hard ticks.

Experimental infection of Rhipicephalus sanguineus with Rickettsia conorii conorii [PDF]
Clinical Microbiology and Infection, 2009 Little is known about the relationships between Rickettsia conorii conorii, the agent of Mediterranean spotted fever (MSF), and its main vector, the brown dog tick Rhipicephalus sanguineus [1]. Matsumoto et al. recently reported a high mortality of Rh. sanguineus group ticks infected with R.

Rickettsia conorii entry into Vero cells [PDF]
Infection and Immunity, 1995 The entry of rickettsiae into eukaryotic cells is mediated by an induced phagocytosis, but rickettsiae have never been observed in a closed phagocytic vacuole. In this study, Rickettsia conorii entry into Vero cells was observed by transmission electron microscopy during a period of 3 to 20 min after bacterium-cell contact.
