We explored how Saccharomyces boulardii might help prevent liver damage caused by Salmonella Enteritidis, a common foodborne pathogen. Using a mouse model, we noticed that pretreatment with S. boulardii significantly reduced the translocation of Salmonella to the liver by 96%.
Additionally, this treatment decreased inflammation and lesions associated with liver injury. These findings suggest that S. boulardii can be a powerful ally in protecting our livers against food poisoning caused by Salmonella Enteritidis.

We aimed to find out if probiotic supplements like lactobacillus acidophilus could help counteract the negative effects of iron fortification, which has been linked to increased diarrhea and food poisoning among children.
In our study with weaning mice, we discovered that high iron diets led to more severe symptoms when infected with Salmonella.
However, when we added lactobacillus acidophilus beforehand, the mice showed less severe symptoms and better intestinal health.
This suggests that probiotics can really help protect gut health against the adverse effects of iron supplements during foodborne infections.

Probiotics reduce Salmonella colonizationEvaluation of avian-specific probiotic and Salmonella enteritidis-, Salmonella typhimurium-, and Salmonella heidelberg-specific antibodies on cecal colonization and organ invasion of Salmonella enteritidis in broilers.
Highly relevant to food safety
We looked at how an avian-specific probiotic could help reduce food poisoning risks linked to Salmonella Enteritidis in poultry. Our study used chicks that received a special probiotic treatment and compared them to a control group.
The results showed a marked decrease in Salmonella Enteritidis colonization in the treated chicks over several days, especially at days 3, 7, and beyond. However, body weight gains appeared similar between both groups.
Overall, our findings suggest that using Lactobacillus acidophilus as part of the treatment may effectively lower Salmonella risks in broilers.

Lacticaseibacillus rhamnosus shows promiseIn Vitro and In Vivo Evaluation of Lacticaseibacillus rhamnosus GG and Bifidobacterium lactis Bb12 Against Avian Pathogenic Escherichia coli and Identification of Novel Probiotic-Derived Bioactive Peptides.
High relevance for poultry health
We explored the potential of Lacticaseibacillus rhamnosus GG as a probiotic treatment against avian pathogenic E. coli (APEC) in chickens. Our study showed that this probiotic significantly reduced APEC colonization in the chickens' cecum and improved the balance of gut microbiota over a 24-hour period.
Through laboratory evaluations, we detected novel bioactive peptides in the probiotic's culture supernatants, which may contribute to its antibacterial properties. While the results are promising for poultry health, more research is needed to optimize its use in real farming conditions.

We explored the effectiveness of a synbiotic treatment combining Bifidobacterium longum and xylo-oligosaccharides in fighting Campylobacter jejuni, a major cause of food poisoning. The treatment was administered either from day one or day fourteen of the chicks' lives.
Our findings showed that early supplementation led to a significant reduction in C. jejuni levels compared to later treatment. However, Bifidobacterium levels did not significantly differ among treatment groups. These results suggest that early synbiotic use alongside other safety measures could help improve poultry meat safety.
