Question

Quizplus · Accepted Answer

Different genetic versions of a particular pathogen are called strains. Strains are variants of a species that differ from one another in some way, such as in their genetic makeup, virulence, or ability to cause disease. Antibodies are proteins produced by the immune system in response to infection, while disease hosts refer to organisms that harbor the pathogen and may transmit it to others.
