Hypothesis

Can the newly isolated phage vB_SalP_LDDK01 effectively control Salmonella Abortusequi in donkey meat?

Conclusion

The phage vB_SalP_LDDK01 can effectively inhibit Salmonella Abortusequi and reduce its contamination in donkey meat.

Supporting Evidence

  • The phage inhibited the growth of Salmonella Abortusequi for about 8 hours.
  • After treatment, bacterial contamination on donkey meat was reduced by up to 4.5 log10 CFU/piece.
  • The phage showed stability at temperatures between 40-70°C and pH levels of 4-12.
  • The phage's genome was 42,378 bp long and lacked virulence and drug-resistant genes.

Takeaway

Scientists found a new virus that can kill harmful bacteria in donkey meat, helping to keep it safe to eat.

Methodology

The study involved isolating the phage from donkey farm bedding, characterizing its biological properties, and testing its effectiveness against Salmonella in donkey meat.

Limitations

The phage has a narrow host range and cannot eliminate all bacteria from the meat surface.
