a person carrying potentially pathogenic microbes without any signs of disease

carrier

2

a person who is a carrier for more than six months

chronic carrier

3

microorganisms present and growing in or on the body but without causing any damage to the host

colonization

4

microorganisms present on the body but not growing or causing damage to the host

contamination

5

a person carrying an infectious microbe for up to six months after the acute stage of the disease

convalescent carrier

6

microbes multiplying in the host and causing damage to the host

a microbe capable of causing disease in a host

pathogen

20

containing white blood cells
