Representative Western blots are shown in Fig. 1a and b (the complete series of Western blots are shown in Fig. S1), with a total of 31 identified immunoreactive proteins (Table 2, Fig. 1i).
Of the three control sera, drawn from volunteers with no history of tularemia, one serum showed low reactivity with the Chaperonin GroEL.
Sera from all 12 tularemia infected individuals showed intense reactivity with the Chaperonin GroEL (FTT_1696).
