Initial sites of localization and multiplication of Pasteurellamultocida were examined in chickens intravenously inoculated with varying doses of bacteria. Sections of lung, liver, kidney, bone marrow and spleen were prepared for light microscopic examination.Tissue sections were stained with the hematoxylin and eosin stain,Gram's stain or the avidin-biotin-peroxidase complex immunoenzymatictechnique. Of...
The concept of genetic penetrance, "the frequency of manifestation of a genetic factor," was introduced by Timofeef-Ressovsky (Naturwissenschaften 19:493,1931). Incomplete penetrance has been used to explain the absence of phenotypic expression when otherwise anticipated. Studies of Embryonic Chick Edema, ECE (Poultry Sci. 77(suppl. 1):69, 1998) have been conducted in order...
Monoclonal antibodies were developed against serotype 3, P-1059 strain of Pasteurella multocida. Enzyme-linked immunosorbent assays (ELISA) were used to detect antibodies in supernatants of hybridoma cells to either a surface protective (2.5 S) antigen prepared from a 2.5% saline extract or lipopolysaccharide (LPS) prepared by the phenol-water method. Forty two...
Monoclonal antibodies (MCA) produced against infectious
laryngotracheitis virus (ILTV) of chickens reacted in
western blotting experiments with several different ILTV
protein bands in the absence of tunicamycin which inhibits
carbohydrate synthesis. Most of the MCA lost their
reactivity in western blotting experiments when extracts of
tunicamycin-treated ILTV CELC were used,...
