FIG. 1.

The new immunochromatographic test (ICT) detected F. tularensis-specific antibodies in serum from a tularemia patient and a human vaccinee, as well as the sera from four different mammalian species. Reactive sera showed a positive test line (T) within 2 to 10 min. All tests were finally read after 15 min. The application of negative serum samples resulted in a negative test line, while the positive control line (C) indicated a valid test function. In the tularemia patient and the vaccinee, seroconversion could be confirmed. CP, conjugate pad; SP, sample application pad.
