Brief Summary

Recent investigations have suggested that the soft tick (Family Argasidae) Carios kelleyi, which is normally a parasite of bats, may sometimes bite humans and transmit Borrelia spirochaetes that could cause tick-borne relapsing fever (TBRF). Carios kelleyi is widely distributed in the United States and Canada and has also been reported from Costa Rica. Unlike many species of argasid ticks that have fast-feeding larvae, C. kelleyi larvae are slow feeders, apparently requiring one to several weeks to engorge.
