Flashcards in Introduction Deck (30)
1

Variolation

Method first used to immunize an individual against Small Pox with material taken from a patient or a recently variolated individual in the hope that a mild but protective infection would result

2

Largest Virus

Pox Virus

3

Viruses were propagated in _______ before  cultures became available.

Viruses were propagated in eggs before  cultures became available.

4

Studing veterinary virology is important because

1. Viruses cause high rates of mortality and morbidity in animals

2. Viral diseases in animals cause financial loss

3. Zoonosis

5

Edward Jenner

Inoculated cowpox matter repeatedly into arms of healthy 8 year old boys who became immune and did not succumb to small pox

6

First discovered viral disease

Foot and Mouth Disease

7

Friedrich Loeffler and Paul Frosch

Passed the first animal virus through a filter - first evidence of animal viruses

8

Pandemic

Infectious diseases that are spread globally

9

Virion

Complete virus particle that consists of an RNA or DNA core with a protein coat sometimes with external envelopes and that is the extracellular infective form of a virus

10

T/F: Viruses contain nucleic acid genome surrounded by a protein coat.

True

11

Virologist

Someone who studies viruses

12

T/F: Viruses are living entities

False

13

Virology

The study of viruses and viral diseases

14

What effect did Rinderpest have on humans?

Led to starvation resulting in the death of an estimated third of the human population of Ethiopia and two-thirds of the Maasai people of Tanzania.

15

Dr. Walter Reed

Known internationally for his discovery that yellow fever was spread through mosquito

16

Dmitri Ivanovski

Used the Chamberland Filter to isolate Tobacco Mosaic Virus

17

_____________ - killed more thatn 5.2 million cattle south of Zambenzi River, Africa.

Rinderpest - killed more thatn 5.2 million cattle south of Zambenzi River, Africa.

18

Smallest Virus

Parvovirus

19

Louis Pasteur

Injected dried, potassium hydroxide treated, infected rabbit brain material into two boys bitten by rabid dogs and both recovered

20

Explain the process of virus replication

Resembles an assmbly line in which various parts of the virus come together from different parts of the host cell to form a new virus particle

21

Charles Chamberland

Invented filter with pores smaller than bacteria - discovery of viruses began with the filter

22

Virus

Broad general terminology used to describe any aspect of the infectious agent and includes the infectious or inactivated virus particle, or viral nucleic acid and protein in the infected cell.

23

Martinus Beijerinck

Called filtered, infectious substance a virus - considered to be the beginning of virology

24

Viroid

Infectious particle smaller than any of the known viruses, an agent of certain plant diseases.  Particle consists only of an extremely small circular RNA molecue, lacking the protein coat of a virus.

25

Oncogenic Viruses

Viruses that cause cancer

26

Peyton Rous

Isolated the first tumor-causing animal virus

27

Eradication of infectious diseases involves

Eradication of infectious diseases involves the complete elimination of the pathogen or diseas causing agent from a defined geograpic region.

28

Zoonosis

Infectious diseases transmitted from animals to people

29

T/F:  Viruses can make energy and proteins by themselves

False

_____________________

Viruses are obligate intracellular parasites

30

Ernst Ruska and Max Knoll

Invented the electron microscope
