CHAIN

MEANING/DEFINITION

1. ____________

the organism's virulence (ability to grow and multiply), invasiveness

(ability to enter tissues), and pathogenicity (ability to cause diseases),

the greater the possibility that the organism will cause an infection.

Infectious agents are bacteria, virus, fungi, protozoa, and parasitic worms.

2.____________

is a place within which microorganisms can thrive and reproduce. For

example, microorganisms thrive in human beings, animals, and

(usually insect).

5.____________

an opening allowing the microorganism to enter the host. This

includes body orifices, mucus membranes, or breaks in the skin.Tubes placed in body cavities, such as urinary catheters, or from punctures
