title: A time-course study of the transfer of immunoglobulin G from blood to tracheal and lacrimal secretions in young turkeys.
abstract: Three-week-old turkeys were injected intravenously with Bordetella avium-specific immunoglobulin G (IgG), and absorbance readings were measured in blood, tracheal washings, and lacrimal secretions using an enzyme-linked immunosorbent assay at various time intervals. IgG was detected in tracheal and lacrimal secretions as early as 5 minutes after injection and peaked at 10 minutes after injection. Thereafter, IgG absorbance declined rapidly, reaching background levels by 24 hours. The absorbance readings of IgG in all three sites were comparable at all times from 10 minutes to 24 hours after administration. The results indicated that movement of IgG from blood to mucosal surfaces in turkeys occurs rapidly.
