1. Effects of Methionine Deficiency on the B Lymphocyte and Immunoglobulins of Cecal Tonsil in Cobb Broilers
ABSTRACT The present study was conducted on one-day-old broilers to investigate the effects of methionine deficiency on B lymphocytes and immunoglobulins (sIgA, IgA, IgG, IgM) in the cecal tonsil of Cobb broiler chicken. Methods including immunohistochemistry (IHC), western blot (WB), quantitative real-time reverse transcriptase-polymerase chain reaction (qR

2. Study on ultrastructure of cecal tonsil of SPF chickens treated with commercial competitive exclusion products and challenged with Salmonella Enteritidis / Estudo da ultraestrutura da tonsila cecal de frangos SPF tratados com produtos comerciais de exclusão competitiva, e desafiados com Salmonella Enteritidis, observados através de microscópia eletrônica de varredura (MEV)
O objetivo deste estudo foi o de avaliar a eficiência da aderência de produtos de exclusão competitiva e de probiótico sobre a tonsila cecal de frangos SPF, com idade de um a doze dias. Através da microscopia eletrônica de varredura, verificou-se a ação destes produtos comerciais com relação a proteção ao epitélio, quando desafiados com Salmonel

3. Eimeria tenella Infection Induces Local Gamma Interferon Production and Intestinal Lymphocyte Subpopulation Changes
The role of intestinal lymphocytes and gamma interferon (IFN-γ) production in protective immunity to Eimeria tenella infection was evaluated in two inbred strains of chickens (SC and TK) that display different patterns of susceptibility to coccidiosis. Oral inoculation of either strain with E. tenella led to parasite invasion of the intestinal cecum and cec

4. Colonization of chicken cecae by Escherichia coli associated with hemorrhagic colitis.
Bacterial enumeration, histologic examination, and immunoperoxidase staining demonstrated the ability of an Escherichia coli strain associated with hemorrhagic colitis (serotype O157:H7) to colonize chicken cecae for up to 90 days postinoculation after a peroral challenge at 1 day of age. The bacteria induced mild, transient, mucous membrane damage confined
