Glycoconjugates as components of receptors for Bordetella avium on the tracheal mucosa or turkeys Open
Summary Bordetella avium is an important respiratory tract pathogen of turkeys. In common with other pathogenic bordetellae, B avium manifests a tissue tropism for cilia of the respiratory tract epithelium. To determine the molecular chara…

An experimental model for subclinical edema disease (Escherichia coli enterotoxemia) manifest as vascular necrosis in pigs Open
Summary An experimental model for subclinical edema disease was developed in weanling pigs. In multiple experiments, 3-week-old pigs were weaned, then inoculated intragastrically with 10 10 colony-forming units of an SLT-IIv-positive strai…

Morphologic characterization of conjunctiva-associated lymphoid tissue in chickens Open
SUMMARY Conjunctiva-associated lymphoid tissue ( calt ) in the eyelids of chickens was studied by gross, histologic, and electron microscopic techniques. Structural features were characterized at 1 day of age and at posthatching week ( phw…

Identification of Bordetella avium antigens recognized after experimental inoculation in turkeys Open
SUMMARY Sera and tracheal washings ( tw ) were used to identify antigens of Bordetella avium recognized during experimentally induced bordetellosis in young turkeys. Pooled sera and tw were examined for antibody by a microtitration aggluti…

Orally administered clonidine as a secretagogue of growth hormone and as a thymotrophic agent in dogs of various ages Open
SUMMARY The growth hormone ( gh ) secretagogue activity of variable dosages of clonidine (16.5, 50, 150, and 450 μg/kg of body weight), given orally mixed with the daily food ration, was evaluated in young and old dogs. Significant ( P < 0…

Characterization of Complement Activity in Turkeys: Evidence for Classical and Alternative Complement Pathways Open
Complement activity in turkey serum was examined by using inhibitors or activators of mammalian complement. Hemolytic test systems using sheep red blood cells sensitized with specific antibody (SSRBC) and horse red blood cells (HRBC) were …

Growth hormone treatment stimulates thymulin production in aged dogs. Open
Diminished thymic morphology and function and a decreased provocative growth hormone (GH) response are characteristic of normal ageing. We have previously demonstrated that bovine growth hormone (bGH) treatment of adult dogs tends to resul…
