Summary: This study investigated the circulation of zoonotic Salmonella strains in commercial broiler farms in Chattogram district, Bangladesh, and found that the majority of the isolates showed resistance to multiple antimicrobials. The prevalence of MDR Salmonella poses a great risk to food safety and public health.

Summary: The study found that hatcheries have a high prevalence of Salmonella isolates with high antimicrobial resistance, with no susceptible isolates, and antimicrobial-resistant isolates from breeder farms can disseminate to the final retail market along the broiler chicken supply chain. The emergence of antimicrobial-resistant Salmonella in hatcheries may be due to the horizontal spread of resistant isolates. Therefore, Salmonella control in hatcheries, particularly its horizontal transmission, is important.

Summary: This study aimed to investigate the prevalence, serovar distribution, antimicrobial resistance, and genotypic analyses of the dominating serovars of Salmonella in chickens from a national study in Korea. The results revealed rapid colony dissemination of multidrug-resistant S. Albany in chicken all over Korea, and highlighted the important role of several operations in Salmonella carriage and transmission in Korea.

Summary: The study revealed that Salmonella strains isolated from chicken embryos in Henan province exhibited high resistance to ampicillin (66.67%) and sulfisoxazole (66.67%), with 67.5% of strains being multidrug resistant and 21.67% confirmed as ESBLs positive. Resistance was found to be serovar-dependent, with ESBLs positive strains showing more multi-resistance than ESBLs negative strains.

Summary: This study showed that adding a phage cocktail to chicken feed effectively reduced Salmonella colonization in chickens, with the optimal dose of phage being 10(5) PFU/day. By the end of the study, no Salmonella was detected in the group that received phage at this dose. Phage treatment also improved the growth performance of challenged birds.

Summary: Salmonella contamination of poultry remains a food safety challenge for broiler processors. This study demonstrated the efficacy of antimicrobial interventions in reducing Salmonella in commercial broiler processing plants and assessed changes in Salmonella serovars before and after the chilling process.

Summary: The study demonstrates that antibiotic-susceptible Salmonella enterica serovar Heidelberg strains can acquire multidrug resistance from commensal bacteria even in the absence of antibiotic selection. Exposure to acidic pH drove the horizontal transfer of antimicrobial resistance plasmids, suggesting that simply removing antibiotics from food animal production might not be sufficient to limit the spread of antimicrobial resistance.

Summary: This study evaluated the prevalence and antimicrobial resistance of Salmonella in conventional and no antibiotics ever (NAE) broiler farms. The study found that conventional farms had higher prevalence of Salmonella and exhibited frequent antimicrobial resistance. Salmonella isolates from NAE broiler farms showed higher rates of antimicrobial resistance compared to conventionally raised chicken.
