Proventricular Glands in Fowl

Infiltrating the Proventricular Glands Proventriculitis in Broiler Chickens: Immunohistochemical Characterization of the Lymphocytes

Broiler chickens with transmissible proventriculitis have severe lymphocytic infiltration of the proventricular glands. The distribution of T cells and B cells in these infiltrates was studied histopathologically, and their identity was confirmed immunohistochemically (CD3, CD4, CD8, and B cells). To reproduce this disease, 1-day-old commercial boilers were orally gavaged with homogenized prove...

Histochemical Detection of Glycoconjugates in the Anterior Lingual Salivary Glands of the Domestic Fowl

Glycoconjugates in secretory epithelium of the anterior lingual salivary glands of chicken have been studied by means of light microscopic histochemical methods. A series of staining procedures were employed including peroxidase labeled lectin diaminobenzidine methods and digestion techniques with neuraminidase or α amylase. The terminal portion of the anterior lingual gland consisted of mucous...

Novel Borna Virus in Psittacine Birds with Proventricular Dilatation Disease

Pyrosequencing of cDNA from brains of parrots with proventricular dilatation disease (PDD), an unexplained fatal inflammatory central, autonomic, and peripheral nervous system disease, showed 2 strains of a novel Borna virus. Real-time PCR confirmed virus presence in brain, proventriculus, and adrenal gland of 3 birds with PDD but not in 4 unaffected birds.
