Fig. 1 — Dispersion of optical densities (A490) obtained with serum samples from ankylosing spondylitis patients with (AU) and without (AS) a history of acute non-granulomatosus anterior uveitis. Detection of IgG serum antibodies against Toxocara canis and Ascaris lumbricoides was performed by enzyme-linked immunosorbent assay. Reactivity of serum from patients with toxocariosis and ascariasis is shown, respectively, in the positive control (PC) group. The samples of healthy donors were used as the negative control (NC). The horizontal line indicates the cutoff value.
