Important diseases that require CMI to control (4)

Herpes (IBR, BHV-1)
BRSV
PI-3
intracellular bacteria

3

4 important diseases that require HUMORAL immunity for control

BVDV
Pasteurella
E. coli
Rota virus

4

3 things that can impact response to a vaccine

high stress
other concurrent infections
nutritional deficiency

5

Which adjuvant is able to specifically effect both B & T cells?

Dual phase polymer lipid

6

Which vaccine type allows for distinction between wild-type infections from vaccination

Gene-deleted vaccine

7

Facial asymmetry, head shaking, and excess nasal discharge are indicative of? How would you confirm?

Enzootic nasal tumor

biopsy (positive apical staining)

8

Sinusitis, rhinitis, and sneezing can all be indicative of? how would you treat?

Oestrus ovis infestation

Ivermectin

9

Sinusitis most commonly occurs secondary to which 2 things?

Dehorning

Abscessed tooth

10

3 causative agents associated with pharyngitis

T. pyogenes
F. necrophorum
C. pseudotuberculosis (causes CLA!!)

11

painful swallowing, anorexia, coughing, and pyrexia with a history of eating rough feedstuff would indicate?

Primary way to diagnose?

Pharyngitis

endoscopy

12

What should you NOT do when treating caseous lymphandenitis?

Lance or lavage (can spread the infection more)

13

Edema and suppuration of the arytenoid cartilages that leads to dyspnea, cyanosis, and anorexia

Laryngeal chondritis

14

This disease is considered congenital and can cause exercise intolerance and coughing; how is it treated?

Tracheal collapse

surgery (prosthetic tracheal rings)

Most common and most important infectious bacterial disease of sheep and goats

2 most common etiologies?

Pasteurellosis

M. haemolytica (mostly)
P. multocida

16

Which biotype of M. haemolytica is the most common isolate in ovine pneumonic pasteurellosis & also commonly causes mastitis in sheep?

A2

17

2 common necropsy findings associated with pasteurellosis

1) fibrinopurulent pleuropneumonia

2) oat cells (surrounding areas of necrosis)

18

Mycoplasma (Enzootic pneumonia, Chronic nonprogressive pneumonia, and atypical pneumonia)

23

2 common routes of exposure for Mycobacterium bovis (TB)

inhalation (most common)

through milk

24

An obligate intracellular bacteria that can cause a dry, hacking cough

28

Most common route of transmission for CAE (carpine arthritis-encephalitis)
