What is a true pathogen and an opportunistic pathogen?
True Pathogen- are capable of causing disease in healthy persons with normal immune defenses ex. influenza virus, plague bacillus, and ect
Opportunistic pathogen- cause disease when the host's defenses are compromised or when they grow in part of the body that is not natural to them
A true pathogen when ever interact with a host will cause a disease, where as a oportunistic pathogen is in normal condition is a normal microbe but in conidtion of immunocompression or in any injury when this get access to internal system of body then they cause disease. A true pathogen is an infectious agent that causes disease in any susceptible host, whereas an opportunistic pathogen causes disease in immunocompromised hosts (people whose immune system…
A non pathogenic organism cause infection in host when the host's immune system is down.It is called as opportunistic pathogen.That infection is known as opportunistic infection. Example for opportunistic pathogen: Candida albicans, Mycobacterium avium-intracellulare, cytomegalovirus (CMV) ---- Pathogen to HIV positive persons.
A pathogen is any organism that can cause disease in humans; this includes numerous viruses, bacteria and fungi. An opportunistic pathogen is an organism that can cause disease in humans, but only under certain ideal conditions. In general, infection with an opportunistic pathogen indicates the person was immuno-compromised. Common causes of immuno-compromise include advanced HIV infection (AIDS), treatment for cancer, long-term corticosteroid administration for metabolic disease, and long-term immune suppression for organ transplants recipients.
