Which *Ornithodoros* species are cited as significant vectors for TBRF in the US context?
Answer
*O. hermsi*, *O. parkeri*, and *O. turicata*.
The text identifies specific species within the *Ornithodoros* genus, a primary group within the Argasidae family, as important vectors for Tick-Borne Relapsing Fever (TBRF) within the United States. These critical vectors include *O. hermsi*, *O. parkeri*, and *O. turicata*. These species are often found closely associated with small rodents nesting near or inside human habitations, thereby directly linking the cycle involving rodents and ticks to human infection risks, especially in rustic settings.
