FIG 1.

Assessment of serological responses to B. turicatae (Bt) protein lysates from mice fed upon by infected O. turicata and O. turicata americanus ticks. Immunoblots from two mice are representative of the remaining animals in each treatment group. Serum samples were used from mice that were fed upon by the following O. turicata (Ot) or O. turicata americanus (Ota)::B. turicatae isolate combinations: Ot-TX::Bt-TX (A), Ot-TX::Bt-FL (B), Ot-KS::Bt-TX (C), Ot-KS::Bt-FL (D), Ota::Bt-TX (E), and Ota::Bt-FL (F). A preinfection (Pre) serum sample is shown (G) and represents the remaining animals. Molecular masses are shown on the left of the immunoblots in kilodaltons.
