The Problem of Invasive Pathogens: How Can We Protect Our Ecosystems from Harmful Microbes?

Annette Uy

Invasive pathogens are microorganisms, such as bacteria, viruses, and fungi, that infiltrate ecosystems where they are not native. Once established, these pathogens can disrupt local biodiversity, threaten native species, and cause significant ecological and economic damage. Their introduction can be accidental, through global trade and travel, or intentional, for specific purposes that unfortunately backfire. Understanding ...
