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
An opportunistic infection is a pathogen that only causes disease in a host with a weakened immune system or other underlying condition. These infections take advantage of the weakened state of the host to cause illness.
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.
Primary Pathogens are the microorganisms that cause diseases in healthy individual. Opportunistic Pathogens are the microorganisms that are ordinarily in contact with the host and cause disease when the host's resistance is low.
Fungi tends to prefer temperatures that are below human body temperature, and to be in darker and moister areas than many tissues in the human body. Without a compromised immune system or other debilitation of the human, fungi generally are not able to survive in humans or cause an infection.
A notable pathogen in the Betaproteobacteria group is Burkholderia cepacia. This bacterium is known for causing respiratory infections, particularly in individuals with cystic fibrosis or chronic lung conditions. Additionally, Burkholderia cepacia can lead to other opportunistic infections and is recognized for its resistance to multiple antibiotics, complicating treatment options.
