Gross pathology photograph of the ovary, oviduct, and adnexa of a chicken with oophoritis caused by infection by Salmonella enterica serotype Gallinarum biovar Pullorum. Note the pedunculated involuting ovarian follicles of abnormal shape containing white granuloma (arrows) interspersed with small, grossly normal ovarian follicles. These findings are nonspecific and may be similar to other ovarian infections.
