Distribution and Ecological Drivers of Spotted Fever Group Rickettsia in Asia [PDF]

EcoHealth, 2019
Spotted fever group and related rickettsia (SFGR) are a neglected group of pathogens that belong to the genus Rickettsia. SFGR are zoonotic and are transmitted by arthropod vectors, primarily ticks, fleas and mites to accidental hosts. These emerging and re-emerging infections are widely distributed throughout the world.

Beyond the Kidney and Lung: Cutaneous and Mucosal Clues to Human Hantavirus Disease

International Journal of Dermatology, EarlyView.
Rodent exposure and aerosolized excreta can lead to hantavirus infection with systemic endothelial injury and capillary leak, resulting in thrombocytopenia and syndromes such as HPS/HCPS and HFRS/NE. Early dermatologic and mucosal findings, including flushing, conjunctival injection, petechiae/purpura, and mucosal bleeding, may provide important clues ...

Detection of Spotted Fever GroupRickettsiaDNA by Deep Sequencing [PDF]

Emerging Infectious Diseases, 2017
After conventional molecular and serologic testing failed to diagnose the cause of illness, deep sequencing identified spotted fever group Rickettsia DNA in a patient's blood sample. Sequences belonged to R. honei, the causative agent of Flinders Island spotted fever. Next-generation sequencing is proving to be a useful tool for clinical diagnostics.

Ticks and spotted fever group rickettsiae of southeastern Virginia

Ticks and Tick-borne Diseases, 2014
The incidence of tick-borne rickettsial disease in the southeastern United States has been rising steadily through the past decade, and the range expansions of tick species and tick-borne infectious agents, new and old, has resulted in an unprecedented mix of vectors and pathogens.
