FGB and babesiosis: Other remarkable changes observed were serum amyloid A (0.4% in the control pool vs. 1.1% in the babesiosis pool), sulfhydryl oxidase (1.3% to 3.3% increase), fibrinopeptide B (1.5% to 2.3%), fibrinogen gamma (0.6% to 1.02%) and coagulation factor V (0.99% to 1.06%), while most other proteins remained at similar levels (Fig 6).
