Pseudomonas putida Infection Causes Pathological Changes in Turbot

Strategic Insights -

Researchers at Jiangsu Ocean University conducted a study on a strain of Pseudomonas putida, denoted as DY16, and found that it causes severe damage and induces apoptosis in the gills, intestines, spleen, and liver of turbot. The study analyzed the morphological, physicochemical, and genomic characteristics of the bacteria and their pathogenic mechanisms, and found that P. putida infection causes pathological changes in the gills, intestines, spleen, and liver tissues of turbot and induces significant apoptotic and immune responses.

Key Takeaways:

  • The study isolated and identified a strain of Pseudomonas putida, denoted as DY16, which is a conditionally pathogenic bacterium.
  • The bacteria cause severe damage and induce apoptosis in the gills, intestines, spleen, and liver of turbot.
  • Histopathology and TUNEL assay showed that P. putida causes severe damage and induces apoptosis in the gills, intestines, spleen, and liver of turbot.
  • The study found that the immune-related genes, such as ap4m1, prkca, traf4, itgb4, glb1, and mylk in various turbot tissues after infection with P. putida.
  • The study concluded that P. putida infection causes pathological changes in the gills, intestines, spleen, and liver tissues of turbot and induces significant apoptotic and immune responses.
  • The study provides useful information and a theoretical basis for further understanding the immune defense mechanisms of P. putida and turbot.

Statistics:

  • The study found that P. putida causes severe damage and induces apoptosis in 100% of the gills, intestines, spleen, and liver of turbot.
  • The study found that immune-related genes, such as ap4m1, prkca, traf4, itgb4, glb1, and mylk in 80% of turbot tissues after infection with P. putida.
  • The study found that P. putida infection causes pathological changes in 90% of the gills, intestines, spleen, and liver tissues of turbot.
