Integrating bacterial and viral genomic information enhances and extends the machine learning predictions of bacteriophage activity against pathogenic Escherichia coli

The use of bacteriophage (phage) to treat bacterial infections is undergoing a resurgence due to the rise of antibiotic resistance. Pathogenic Escherichia coli, including extraintestinal pathotypes such as uropathogenic E. coli (UPEC), pose a substantial clinical burden with the challenge of multi-drug resistance strains, making it important to progress alternative treatment options such as those…

Phage therapy is regaining attention as a solution to antibiotic-resistant bacterial infections, particularly pathogenic Escherichia coli strains like uropathogenic E. coli (UPEC). Predicting phage activity against unseen E. coli strains relies on machine learning models that incorporate bacterial genome data. However, these models lacked phage gene content, hindering their ability to generalize.

By integrating bacterial and phage pangenomes into a single predictive model, researchers have enhanced the accuracy of predicting phage-E. coli interactions. This unified approach, dubbed PanPhage, incorporates gene content from both phage and bacteria as machine learning features. The model's predictive prowess was demonstrated through leave-phage-out analyses, accurately predicting activity for phages with no training data.

Key bacterial determinants influencing prediction included surface recognition and anti-phage defense mechanisms, alongside phage-specific factors. PanPhage represents a significant advancement in capturing genetic information relevant to various stages of the phage-host interaction.

Crown-of-thorns starfish can help reefs thrive

Crown-of-thorns starfish (COTS) are infamous in the marine world. Their toxin-loaded thorns give them a menacing appearance, and they have a reputation as destroyers of coral reefs. New research from the University of Sydney challenges the perception of COTS as purely destructive.

Delaying cherry blossom to reduce frost damage

Climate change is causing many fruit trees to flower earlier, increasing their exposure to damaging late spring frosts. A study led by the University of Göttingen shows that the plant growth regulator ethephon can delay flowering in Kordia, a sweet cherry variety, potentially protecting blossoms and developing fruitlets from frost.
