Lactobacillus aids gut health during infections
Probiotic/prebiotic correction for adverse effects of iron fortification on intestinal resistance to Salmonella infection in weaning mice.
High relevance for gut health
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.

Lactococcus lactis reduces food toxins
Anti-Staphylococcal Enterotoxinogenesis of in Algerian Raw Milk Cheese.
High relevance for food safety
We investigated how a specific strain of Lactococcus lactis can help prevent food poisoning caused by a common pathogen found in raw milk and cheese. Our results showed a significant decrease in pathogen levels—by around 3 log CFU/mL—within just six hours when this strain was present.

Even more promising, it reduced the production of staphylococcal enterotoxin A (SEA) by 79%. In cheeses made with Lactococcus lactis, SEA was never detected, while it was found in higher levels in cheeses made without this protective strain. This study clearly shows Lactococcus lactis's potential in enhancing food safety through biopreservation.

Lactococcus lactis vaccine shows efficacy
Oral immunization with Lactococcus lactis secreting attenuated recombinant staphylococcal enterotoxin B induces a protective immune response in a murine model.
Highly relevant to food safety
We explored how Lactococcus lactis, when engineered to produce a harmless version of staphylococcal enterotoxin B (SEB), can offer protection against food poisoning caused by Staphylococcus aureus. In our study, mice that received the oral vaccine developed strong immune responses and were better able to survive challenging infections. Those immunized had significantly reduced bacterial counts in their spleen and higher levels of protective antibodies. This promising approach highlights the potential of using modified bacteria as vaccines against foodborne illnesses.

Probiotics reduce Salmonella colonization
Evaluation 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.

Bifidobacterium longum reduces food pathogens
Evidence of Campylobacter jejuni reduction in broilers with early synbiotic administration.
Study relevant for poultry safety
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.

Synbiotic reduces C. jejuni in poultry
A Bifidobacterium-based synbiotic product to reduce the transmission of C. jejuni along the poultry food chain.
Highly relevant to food safety
We aimed to see how a synbiotic mixture might help reduce Campylobacter jejuni, a harmful bacteria often found in poultry, which can cause food poisoning in humans. Through our research, we provided broiler chickens with a blend of prebiotics and a specific strain of Bifidobacterium longum.

After 14 days, we observed a significant reduction in C. jejuni levels in the feces of treated chickens. This suggests that such synbiotic treatments could be an effective strategy for enhancing poultry safety and reducing foodborne illnesses linked to poultry products.

B. longum reduces Campylobacter in poultry
Characterization of probiotic strains: an application as feed additives in poultry against Campylobacter jejuni.
High relevance for food safety
We explored the effectiveness of two probiotic strains, specifically Lactobacillus plantarum PCS 20 and Bifidobacterium longum PCB 133, in reducing Campylobacter jejuni in poultry. After thorough screening of 55 bacteria for their ability to combat this common pathogen, B. longum was found to thrive in the chickens' digestive systems after two weeks, while L. plantarum was undetectable. Most importantly, B. longum significantly lowered C. jejuni levels in feces, suggesting its potential as a feed additive to improve food safety.
