Description
Ivo Sedláček and co-authors describe, in a 2025 taxonomy study, two cold-tolerant bacterial species new to science, found in Magellanic penguin droppings in Argentine Patagonia. Samples gathered in 2016 and 2017 yielded two strains that early gene reads placed in the genus Erwinia, a group better known from plants.
Whole-genome comparisons showed the strains match no named species, and differ enough from each other to count as two. Form and chemistry tests backed the split. They are named Erwinia psychrophila and Erwinia magellanica, and their type strains now sit in two public collections. Since some Erwinia species blight crops, knowing the family's wild members sharpens both ecology and plant protection. Penguin colonies, it seems, host more than birds.
