Abstract
Salmonella is a critical group of zoonotic pathogens that are widely spread in poultry, causing avian salmonellosis. This disease usually leads to significant reductions in poultry performance, including reduced egg production in laying hens, decreased hatchability in chicks, and retarded growth in broilers. As a result, worldwide poultry industry suffers serious economic losses. Vaccination serves as an essential strategy for preventing Salmonella infection in poultry, effectively reducing susceptibility and alleviating disease symptoms, while also minimizing fecal shedding and environmental contamination. This subsequently diminishes public health risks. Various Salmonella vaccines can induce humoral and cellular immune responses to different extents. Therefore, a thorough understanding of the immune defense mechanisms, especially adaptive immune responses in poultry infected with Salmonella, is crucial for the development of Salmonella vaccines. This review summarizes the progress in the application of Salmonella vaccines in poultry, including adaptive immune responses induced by Salmonella and vaccines targeting the predominant circulating serotypes in poultry. It also provides an insight into the future of poultry-origin Salmonella vaccines.
期刊介绍：
The journal reports basic, comparative and clinical immunology as they pertain to the animal species designated here: livestock, poultry, and fish species that are major food animals and companion animals such as cats, dogs, horses and camels, and wildlife species that act as reservoirs for food, companion or human infectious diseases, or as models for human disease.
Rodent models of infectious diseases that are of importance in the animal species indicated above,when the disease requires a level of containment that is not readily available for larger animal experimentation (ABSL3), will be considered. Papers on rabbits, lizards, guinea pigs, badgers, armadillos, elephants, antelope, and buffalo will be reviewed if the research advances our fundamental understanding of immunology, or if they act as a reservoir of infectious disease for the primary animal species designated above, or for humans. Manuscripts employing other species will be reviewed if justified as fitting into the categories above.
The following topics are appropriate: biology of cells and mechanisms of the immune system, immunochemistry, immunodeficiencies, immunodiagnosis, immunogenetics, immunopathology, immunology of infectious disease and tumors, immunoprophylaxis including vaccine development and delivery, immunological aspects of pregnancy including passive immunity, autoimmuity, neuroimmunology, and transplanatation immunology. Manuscripts that describe new genes and development of tools such as monoclonal antibodies are also of interest when part of a larger biological study. Studies employing extracts or constituents (plant extracts, feed additives or microbiome) must be sufficiently defined to be reproduced in other laboratories and also provide evidence for possible mechanisms and not simply show an effect on the immune system.
