Cross-protection conferred by a live-attenuated Salmonella enteritidis vaccine against challenge with Salmonella Heidelberg and Salmonella infantis
Salmonella infections cause enteric diseases in humans and animals, and poultry production is generally associated with contamination by this foodborne pathogen. S. enteritidis (SE) and S. typhimurium (ST), as well as other serotypes such as S. Heidelberg (SH) and S. infantis (SI), are highly prevalent. This study evaluated the protection conferred by a live SE vaccine (auxotrophic for the amino acids adenine and histidine) in laying hens exposed to field strains of SH or SI.

Virulence genes and antimicrobial susceptibility in Salmonella enterica serotypes isolated from swine production in Argentina
Summary Salmonellais a worldwide-distributed pathogen that affects both humans and animals and is usually associated with intensive animal production such as poultry and swine. This bacterium carries different virulence genes, whose expression favors its interaction with the host and may influence the course of the infection. Extended usage of antibiotics for metaphylaxis or prophylaxis and as growth promoters favors the emergence of multiresistant Salmonella strains.
IgY Technology: Extraction of Chicken Antibodies from Egg Yolk by Polyethylene Glycol (PEG) Precipitation
The choice of a suitable IgY purification method is influenced by scale of purification (laboratory or industrial), cost effectiveness, technology (laboratory equipment), and impact on the environment (waste management). Various IgY extraction methods were reviewed in detail by De Meulenaer & Huyghebaert (2001, for review see also Schade et al. 2005).
