1

Example of a large virus

Pox virus

2

Example of a small virus

Parvovirus

3

A virus like protein
AKA spongiforms
Ex: Mad Cow Dz

Prions

4

A protective protein coating that all viruses have

Capsid

5

Infect bacteria ONLY

bacteriophage

6

Lipid membrane surrounds the virus and readily absorbed by cells
Cause persistent infxs
Ex: chicken pox, herpes, flu, rabies,

Envelope viruses

7

Do not possess an envelope
More difficult to disinfect (steam sterilization is needed)
Ex: parvovirus

Naked viruses

8

4 stages of virus replication

1. Attachment
2. Penetration/Uncoating
3. Replication and synthesis
4. Assembly and release

9

Most common mucosal surface viruses enter through

Respiratory system

10

Which step of virus replication does the virus attach to a host cell?

Attachment

11

Which step of virus replication does the virus produce enzymes to break down the host cell membrane and the genome enters the host cell?

Penetration/Uncoating

12

Which step of the viral cycle is when the virus replicates itself to ensure it's survival where the DNA or RNA redirects the host cell DNA to ignore it's own needs?
The prodromal period (immune system is activated)

Replication

13

Which step of the viral cycle is where the viral components come together to form virons, the cell ruptures and dies, and the virons are released into the environment?

Assembly/Release

14

Virus particles

virons

15

Systemic viral infx

Viremia

16

Type of viral infx that produces C/S (can be acute or chronic)

Apparent

17

Type of viral infx where there is no outward C/S
Ex: AIDS, FIV

Non-apparent/Sub clinical/Silent

18

HIGHLY contagious feline virus that cats will have their whole life
C/S: S+, conjunctivitis, rhinitis, F+, anorexia, corneal ulcers (in severe cases)

Feline Herpes Virus

19

Supplement given to cats for management of herpes

Lysine

20

Caused by a retrovirus that affects bone marrow
Transmitted by close contact
C/S: repro problems, F+, D+, susceptible to other infections

Feline Leukemia Virus (FeLV)

21

Caused by a lentivirus
AKA Feline AIDS
Transmitted via bites and severely compromises immune system

Feline Immunodeficiency Virue (FIV)

22

Caused by a parvovirus
AKA Feline Distemper
C/S: abortion in queens, cerebellar hypoplasia in neonates, GI symptoms, dehydration

Panleukopenia

23

Rhabdovirus causes

rabies

24

Causes "Fading Puppy Syndrome"
C/S: ADR, crying, abdominal pain, acute death
Adult K9 usually show no signs, but can pass to neonates

Canine Herpesvirus

25

Warts that resolve on their own
1-2 mos incubation and INCREDIBLY contagious

Canine Oral Papilloma Virus

26

Caused by a paramyxovirus
AKA "Hard Pad Dz"
C/S: dehydrated foot pads, F+, lethargy, anorexia, C+, d+, v+

Canine Distemper Virus

27

Causes canine hepatitis
Similar to Parvo in C/S

Canine Adenovirus

28

Causes explosive, bloody D+ especially in young pups
Dehydration is a concern, so treated with IV fluids and pepsid
Naked virus that is hard to kill on an inanimate surface

Canine Parvovirus

29

Attacks the intestinal villi of dogs

Canine Coronavirus

30

Enveloped virus that causes Gastroenteritis in pups

Canine Rotavirus
