Salmonella spp. is a facultative intracellular pathogen causing localized or systemic infections, involving economic and public health significance, and remains the leading pathogen of food safety concern worldwide, with poultry being the primary transmission vector.
- Antibiotics have been the main strategy for Salmonella control for many years, which has allowed producers to improve the growth and health of food-producing animals.
- However, the utilization of antibiotics has been reconsidered since bacterial pathogens have established and shared a variety of antibiotic resistance mechanisms that can quickly increase within microbial communities.
This review from Ruvalcaba-Gómez et al. (2022) summarizes and discusses the main available antibiotic-free strategies for Salmonella control in poultry and their efficiency in preventing Salmonella infection and reducing its adverse effects, besides exploring complementary approaches based on the -omics as a tool to their assessment.
Materials and Methods
Sources of the Data and Search Strategy:
- “This study aimed to review the available reports on the use of antibiotic-free strategies for Salmonella control in poultry, focusing on the feeding- and non-feed-based strategies. For this, a comprehensive search was performed online through Web of Science, PubMed, and SCOPUS databases”
- Inclusion criteria: articles where the authors applied antibiotic-free strategies: prebiotics, probiotics, synbiotics, postbiotics, phytobiotics, bacteriophages, in ovo applications, and vaccines to control Salmonella infections in challenged laying hens, broilers, turkeys, and quails.
