1

What is the etiology of Mycotic Nasal Granuloma?

Rhinosporidia spp.

Helminthosporum spp.

2

This fungal nasal condition in cows is

more common on irrigated pastures in warm/hot climates.

It is caused by a hypersensitivity reaction and results in the

signs like hemorrhage, head shaking, nasal rubbing,

and upper respiratory tract signs.

Mycotic Nasal Granuloma

3

How is Mycotic Nasal Granuloma treated?

NOT with Abx!

Use Systemic Iodine and/or Surgery

4

Which breed of cow is predisposed to allergic rhinitis?

Jersey

5

How is allergic rhinitis diagnosed?

Eosinophilia seen on nasal secretions

6

This type of sinusitis is associated with dehorning.

It can be avoided by getting polled breeds, or by

dehorning when they are calves when their horns have less

communication with that particular sinus. 

 

Frontal sinusitis

7

This type of sinusitis is associated with horses with bad or infected teeth.

It can be caused by extension of infections such as 

Actinomyces (bone) 

or Actinobacillosis (soft tissue)

Maxillary sinusitis

8

In regards to sinusitis,

a bulge on the side of the face is due to ______ sinusitis

where as

a bulge between the eyes is due to _________ sinusitis

In regards to sinusitis,

a bulge on the side of the face is due to Maxillary sinusitis

where as

a bulge between the eyes is due to Frontal sinusitis

9

How is sinusitis treated?

Surgery, flush the sinus, and ANTIBIOTICS

10

What is the most common etiology of pharyngeal trauma and abscess?

Improper admin of pills per os

or

oral dewormers

11

What type of dyspnes would you expect in

a cow with pharyngeal trauma and abscess?

inspiratory dyspnea

(with stertor sounds due to swelling in the pharynx)

12

T/F:

Bloat can be a sign of pharyngeal trauma and abscess

TRUE!

Abscess or swelling of pharynx puts pressure,

and animal cannot swallow or let gas out

13

What are the 3 DDx associated with pharyngeal trauma and abscess?

Neoplasia (LSA in old animals)

Necrotic Laryngitis

Rabies

14

How do you treat pharyngeal trauma and abscess?

Drainage, flushing, and ABX

15

Calf Diphtheria is also known as 

Necrotic Laryngitis

16

What is the etiology of Necrotic Laryngitis (Calf Diphtheria)?

Fusobacterium necrophorum

17

Necrotic Laryngitis (Calf Diphtheria)

is more common in which type of cattle?

BEEF calves kept on wet, moist pasture

18

A beef calf out at pasture during the rainy season

has severe inspiratory dyspnea, LOUD stertor,

and fetid odor of the breath.

This has occurred acutely, and the calf is still nursing.

What is your most likely diagnosis?

Necrotic Laryngitis (Calf Diphtheria)

19

Necrotic Laryngitis (Calf Diphtheria)

can cause this problem in adult cattle

Foot rot

or

Liver Abscesses

20

What is used to treat Necrotic Laryngitis (Calf Diphtheria)?

Procaine Penicillin G

or

Oxytetracycline

+ NSAIDs

21

Tracheal Edema Syndrome is also known as _______

and is most common in steers in feedlots

Honker Syndrome

22

What 2 factors are required to cause

Cattle Shipping Fever (Bovine Respiratory Disease- BRD)?

STRESS

and the

ORGANISM

23

What are the 4 organisms part of the normal flora

that causes Cattle Shipping Fever (Bovine Respiratory Disease- BRD)

when conditions are right?

Mycoplasma

Mannheimia

Histophilus

Pasteurella

24

_________ is the #1 factor contributing to Respiratory Disease

in cattle.

COMINGLING

(Mixing of cattle = #1.

Shipping = #2)

25

How is weaning a stress factor for the development of

Cattle Shipping Fever (Bovine Respiratory Disease- BRD)?

Separation anxiety in both the calf and cow

results in the cow constantly calling for the calf.

This causes damage to respiratory epithelium and

allows pathogens to colonize.

Also, calving causes immunosuppression which is another factor.

26

What are the 4 core vaccinations that cattle receive

to prevent respiratory disease?

IBR 

Parainfluenza

BRSV

BVD

27

What is the etiology of Infectious Bovine Rhinotracheitis (IBR)?

Bovine Herpesvirus-1 (BHV-1)

28

T/F:

Dairy cattle are more prone to Infectious Bovine Rhinotracheitis (IBR)

FALSE!

FEEDLOT cattle are more prone

29

A beef cow on a feedlot presents with a VERY high fever of 105F.

She has profuse serous nasal discharge,

but normal lung sounds are heard.

On ocular exam, a central corneal ulcer is found.

A couple other cows have aborted and have pustules on their vulvas.

What is your primary differential?

 

Infectious Bovine Rhinotracheitis (IBR)

30

This clinical sign of Infectious Bovine Rhinotracheitis (IBR)

is more common in DAIRY cattle than in feedlot cattle with IBR.

Infectious Pustular Vulvovaginitis
