👉 Possession-infection, also known as endosymbiotic infection, is a unique relationship where one organism (the pathogen) gains possession of another organism (the host) by integrating into its cellular structure or metabolic processes. This often occurs during symbiotic interactions, such as when bacteria live inside plant cells or when viruses hijack host cells to replicate. Unlike typical infections where pathogens invade and multiply outside the host, possession-infection involves a more intimate and long-term relationship, where the pathogen's survival and reproduction are closely tied to the host's well-being. This can lead to beneficial outcomes for both parties, such as enhanced nutrient uptake or protection against other pathogens, but it also poses risks if the infection becomes pathogenic, potentially causing disease. The term highlights the complex interplay between the host and the invading organism, where possession facilitates infection by providing a protected environment and resources.
