The intracellular bacterium Rickettsia rickettsii exerts an inhibitory effect on the apoptosis of tick cells [PDF]
Parasit Vectors, 2020 Rickettsia rickettsii is a tick-borne obligate intracellular bacterium that causes Rocky Mountain spotted fever, a life-threatening illness. To obtain an insight into the vector–pathogen interactions, we assessed the effects of infection with R ...

Hosts mobility and spatial spread of Rickettsia rickettsii [PDF]
PLOS Computational Biology, 2018 There are a huge number of pathogens with multi-component transmission cycles, involving amplifier hosts, vectors or complex pathogen life cycles. These complex systems present challenges in terms of modeling and policy development.

Comparative Susceptibility of Different Populations of Amblyomma sculptum to Rickettsia rickettsii [PDF]
Frontiers in Physiology, 2019 The bacterium Rickettsia rickettsii is the etiological agent of Brazilian spotted fever (BSF), which is transmitted in Brazil mainly by the tick Amblyomma sculptum. Herein, larvae and nymphs of six populations of A. sculptum were exposed to R. rickettsii

The Transcriptome of the Salivary Glands of Amblyomma aureolatum Reveals the Antimicrobial Peptide Microplusin as an Important Factor for the Tick Protection Against Rickettsia rickettsii Infection [PDF]
Front Physiol, 2019 The salivary glands (SG) of ixodid ticks play a pivotal role in blood feeding, producing both the cement and the saliva. The cement is an adhesive substance that helps the attachment of the tick to the host skin, while the saliva contains a rich mixture ...

Rickettsia rickettsii Co-feeding Transmission among Amblyomma aureolatum Ticks [PDF]
Emerging Infectious Diseases, 2018 Amblyomma aureolatum ticks are vectors of Rickettsia rickettsii, the etiologic agent of Rocky Mountain spotted fever in Brazil. Maintenance of R. rickettsii in nature depends on horizontal transmission along tick generations.
