👉 Possessive infection refers to a condition where an infectious agent, such as bacteria, viruses, or parasites, is directly associated with or embedded within the tissues or cells of a host organism. This means that the pathogen not only exists externally but also has a direct, often intimate, connection to the host's body, potentially leading to localized damage or systemic effects. For example, a bacterial infection like tuberculosis can infect specific areas of the lungs, while HIV can directly infect immune cells within the body. The term highlights the intimate relationship between the pathogen and its host, emphasizing how the infection can cause significant harm by targeting specific tissues or organs.
