f. Staphylococcus aureus can infect wounds in surgery patients OPPORTUNISTIC PATHOGENS
Step-by-step explanation:
Primary pathogens are the organisms that can cause diseases when they enter the body. This means , they are capable of overpowering the body immunity to cause infections.
The opportunistic pathogens are the microorganisms that are present in the body, capable of causing infections, but are be restricted by the body immunity. Therefore , whenever the immunity is compromised, they instantly begin to cause infections.
Reservoirs are organisms that can successfully carry pathogens in their body without being infected. But , they can transfer the pathogens to other people when they come in conyact with them maybe through biting.
