Serologic evidence of Orientia infection among rural population, Cauca Department, Colombia. Western blot analysis was performed using Vero cell extracts and O. tsutsugamushi Karp strain whole-cell antigens. Examples of some reactive samples that were applied to probe-migrating Orientia-specific antigens (56 kD and 47 kD) are shown: A) samples H479 and H499; B) samples H478 and H503. Red arrows indicate 56-kD protein, and blue stars indicate 47-kD protein. OTK, O. tsutsugamushi Karp strain; PL, protein ladder; VC, Vero cell; (‒) C, negative control; (+) C, positive control.
