Detailed explanation-1: -Opportunistic pathogens (OPs) are typically characterised in the medical literature as organisms that can become pathogenic following a perturbation to their host (e.g., disease, wound, medication, prior infection, immunodeficiency, and ageing).

Detailed explanation-2: -Opportunistic pathogens cause infections by taking advantage of the weakened immunity of the host, disturbance in the normal microbiota, or penetrating barriers as in case of traumas. Moreover, opportunistic pathogens may cause mild infections in healthy individuals.
