Question: Primary pathogen, opportunistic pathogen, and reservoirs are terms used to describe infections and infection cycles. sort the descriptions of these terms to the correct box below.
A primary pathogen is a microorganism that can cause disease in a healthy host. It has the ability to overcome the host's immune defenses and establish an infection. Examples of primary pathogens are influenza virus, tuberculosis bacteria, and malaria parasite.
An opportunistic pathogen is a microorganism that normally does not cause disease in a healthy host, but can take advantage of a weakened or compromised host and cause an infection. It may be part of the normal flora of the host or acquired from the environment. Examples of opportunistic pathogens are Candida albicans, Pseudomonas aeruginosa, and HIV.
A reservoir is a source of infection, where the pathogen can survive and multiply. It can be an animal, a human, or an environment. A reservoir can transmit the pathogen to a susceptible host directly or indirectly. Examples of reservoirs are rodents for plague bacteria, bats for rabies virus, and soil for tetanus bacteria.
To summarize, primary pathogens can infect healthy hosts, opportunistic pathogens can infect weakened hosts, and reservoirs can harbor and transmit pathogens. These terms help us understand how infections occur and how to prevent them.
