  • a Bands with boldface designations demonstrated significant association with B. quintana endocarditis compared to that with B. quintana bacteremia and B. henselae endocarditis (P < 0.05). The number in each protein band designation represents the apparent molecular mass in kilodaltons.

  • b Proportion of sera recognizing each band. Results equal to zeros are omitted to improve clarity.

  • c NS, not significant.
