Transmitted by a fomite

Spread by direct contact

2. Thre structure of a virus includes:

A cell wall and membrane

Metabolic enzymes for replication

A protein coat and DNA or RNA

A slime capsule and cilia.

3. The principle of Universal Precautions is based on:

Using disinfectants at all times

Not touching any open or bleeding lesions

Sterilizing all instruments

Assuming that all body fluids from all individuals are possible sources of infections.

4. An anaerobe thrives and reproduces best in:

A moist enviroment

An acidic medium

Air at a cool temp.

The absence of oxygen

5. Microbial mutation mean that:

Genetic infomation and some microbial characteristics have changed

Pathogens become nonpathogens

The mircrobe survives adverse conditions.

The immune response to the microbe is strengthened

6. A retrovirus as HIV contains:

RNA and enzymes for its conversion.

A double strand of DNA

Many enzymes to control

Numerous mitochondria.

7. What does the term carrier mean?

A person with active infections

Animals, insects, objects or surfaces contaminated

An individual who is contagious through infected secretions

A healthy person whose body harbors pathogens and can transmit them to others

8. Bacteria that form a cluster of sheres are called:

Bacilli

Dipococci

Staphylococci

Streptococci

9. What method do viruses use to replicate?

Binary fission

Budding of a daughter cell from the parent cell

Producing reproductive spores

Using a host cell to produce and assemble components

10. The prescene of the bacteria capsule:

Promotes attachment of the bacteria to tissue.

Protects the microbe from phagocytosis

Increases the release of toxins and enzymes

Prevebrs replication of the bacteria.

11. Host resistance is promoted by all of the following except:

Prescribed immunizations

Chronic repiratory disease

Vitamin and mineral supplements

Appropriate inflammatory or immune response

12. A bacterial endospore can:

Also be classified as an acid-fast bacterium.

Exist in latent form inside a host cell.

Reproduce very rapidly.

Survive high temperatures and dry environment.

13. Which of the following is a characteristic of rickettsia?

It is a very small gram-negative intracellular microbe

It exists in three forms

It causes a sexually transmitted disease

It reproduces by budding

14. Entamoeba histolytica is transmitted by:

Mosquitoes

Inhaling contaminated particles

Sexual intercourse

Cysts in feces, contaminating food/water

15. What does a vaccine contain?

Attenuated (weakend) or dead pathogens or their toxins

Antibodies for a specific pathogen

Memeort B and T

Chemicals to stimulate the immune response.

16. The yeasts:

Are usuakky considered to be pathogenic

Consist of clusters of cells.

Many cause opportunistic infection in the body

Are normally not found in resident flora.

17. Transmission of microbes by direct contact includes:

Touching a contaminated countertop

Sexual intercourse

Drinking contaminated water

Inhaling dust

18. How do antiviral drugs act?

Interfering with cell wall development

Decreasing cell membrane permeability

Destroying new, immature viral particles

Reducing the rate of viral replication.

19. Fungi reproduce by:
1. budding
2. extension
3. binary fission
4 production of spores

2,3,4

20. Which area of the body is sterilea?

Stomach

Pharynx

All mucous membranes

Vagina

21. Which of the following is a characteristic of resident or normal flora (microflora)?

It exists in all areas of the body

Different species inhabit various areas of the body

It is of no benefit to human host

It consists only of bateria

22. Which of the following is not classified as protoza?

Plasmodium vivax

Trichomonas vaginalis

Mycoplasma pneumonia

Entamoeba histolytica

23. What do clinical signs of infection appear?

As soon as pathogens penetrate

Quickly when microbe replicate

When yhe mircrobial colony is large enough to damage

After the immune system is activated.

24. Which of the following factors would not be increase the virulence of a specific mircobe?

Secretion of endotoxin

Presence of bacterial capsule

Production of interferons

Secretion of invasive enzymes

25. Opportunistic infection may develop when:

Pathogens enter the body but cannot colonize

A member of the resident flora

Host resistance increases

Contaminated food
