d             normal microbiota e       commensals

 

2              Choose the term-definition pair that is mismatched? a   fimbriae - adherence to substrate

b             capsules - antiphagocytic factor c              coagulase - dissolve fibrin clots

d             leukocidins - damage white blood cells e               hemolysins - damage red blood cells

 

3              Keratinase has the greatest effect on which of the options below a         respiratory system.

b             gastrointestinal system. c             urinary system.

d             genital system. e              skin.

 

4              A symptom is

a              an objective indication of disease. b        a subjective indication of disease.

c              measurable by health care personnel. d                a temperature.

 

5              Choose which of the following is an example of sequelae? a       headache from meningitis

b             difficulty swallowing from streptococcal infection c          arthritis from Lyme disease

d             diarrhea from Salmonella enteritidis infection

 

6              Animals that participate in the life cycles of pathogens and transmit pathogens from host to host are referred to as

a              fomites.

b             aerosols.

c              mechanical vectors. d    droplet nuclei.

e             biological vectors.

 

7              A laboratory technologist splashed a blood specimen onto his face, eyes, nose, and mouth. This specimen was from an HIV positive patient. If this blood exposure leads to HIV infection in the technologist, the transmission route is considered to be

 

a              direct.
