Influence of Live Attenuated Vaccines on Cecal Microbiome Composition and Microbiota Abundances in Young Broiler Chickens.

Salmonellosis is a global food safety challenge caused by , a gram-negative bacterium of zoonotic importance. Poultry is considered a major reservoir for the pathogen, and humans are exposed through consumption of raw or undercooked products derived from them. Prophylaxis of in poultry farms generally mainly involves biosecurity measures, flock testing and culling, use of antibiotics, and vaccination programs.

Genome Sequences and Phylogeny of Two Duck Hepatitis B Viruses.

Duck hepatitis B virus (DHBV) infection in Pekin ducks is a model for human hepatitis B. Sequence variations may contribute to host therapy responses against the virus. We provide full genome sequences of two DHBVs from France, their phylogenetic classification, and their sequence variability.
