Borrelia hermsii is a blood-borne pathogen transmitted by the argasid tick Ornithodoros hermsi. Since spirochaete clearance in mice is associated with an IgM-mediated response, an immunoproteomic analysis was used to identify proteins reactive with IgM. We report that IgM from both mice and human patients infected with B. hermsii not only reacted with the previously identified variable membrane...

In July 2013, a resident of the Bitterroot Valley in western Montana, USA, contracted tickborne relapsing fever caused by an infection with the spirochete Borrelia hermsii. The patient's travel history and activities before onset of illness indicated a possible exposure on his residential property on the eastern side of the valley. An onsite investigation of the potential exposure site found th...

The relapsing fever spirochete, Borrelia hermsii, alternates infections between a mammal and a tick vector. Whether the spirochete changes phenotypically in the different hosts was examined by allowing the tick vector Ornithodoros hermsi to feed on mice infected with serotype 7 or serotype 8 of B. hermsii. Upon infection of ticks, the spirochetal serotype-specific variable major proteins (Vmps)...

Coxiella burnetii is known for its potential as veterinary and human bacterial pathogen. The bacteria have been described in ticks, but their role transmission of Q fever humans considered low. endosymbionts closely related to C. also isolated from an extensive range tick species evidence growing that these could be linked bacteremia. aim this study was get new information on the presence ticks...

Abstract In a follow-up to the investigations of soft ticks identified from seabird nest soil and litter collected coastal islands Republic Korea (ROK), Ornithodoros sawaii capensis were assessed for presence identification rickettsiae. Ticks samples 50–100 g nests individually by morphological techniques, species confirmed sequencing mt-rrs gene. Subsequently, tick DNA preparations screened ri...
