Abstract
- The crop (ingluvies), an organ for food storage in most avian species when the proventriculus is full, is located at the base of the esophagus. Little is known about any immunological capacity in the crop, and the current study was conducted to determine whether any antibodies to SE could be found in crop flushes taken from White Leghorn hens following infection with this organism. Surprisingly, an exceptionally strong IgA anti-SE response could be detected in the crops of hens 17 d postchallenge, and a comparison at Day 22 of crop vs. intestinal IgA anti-SE responses showed a good correlation between anti-SE antibody levels in the two regions. Histologic examination of crop tissues revealed development of lymphoid aggregates in the crop walls following challenge with SE. These results indicate that the crop may serve a role in immune protection in addition to its capacity as a food storage organ.
