The vector, the
Ornithodoros turicata tick, is endemic to Texas and Florida (4); but although published cases in Texas have been supported by serology for the TBRF group, exposure location, and tick collections (4,5), to the best of our knowledge, successful identification of B.
Notably, cases in Texas occurred more frequently in winter months and were associated with time spent in caves, which likely represents infection with Borrelia turicatae, another species of TBRF Borrelia transmitted by
Ornithodoros turicata ticks (5).
"We have
Ornithodoros turicata found throughout Florida, in southern Georgia, along the Gulf Coast, and from Kansas to East Texas," says Endris.
