Respiratory Flashcards
What is an MDx, most likely etiology, and name of disease for the following image on a young bovine?
Fibrinous rhinitis: MDx
Bovine Herpesvirus-1
Infectious Bovine Rhinitis (IBR; diptheritic membrane)
An oestrus ovis infestation in a sheep will result in (most accurately) a __________ rhinitis.
A. Eosinophilic
B. Atrophic
C. Catarrhal
D. fibrinopurulent
C. Cattarhal (or mucopurulent)
Maybe eosinophilic, but this wouldnt be the primary feature of the rhinitis.
The circled lesions are most likely to be caused by what etiology?
A. Porcine Cytomegalovirus
B. Bordetella Bronchiceptica
C. Porcine Respiratory Syncitial Virus
D. Pasteurella multocidans
D. A, B, and D only
E. B and D only
E.
B. bronchiceptica and P. multocidans cause a multifactorial disease in young pigs called Atrophic Rhinitis, which is prevalent on farms and is routinely screened for in slaughterhouses by making cross-sections of the snout b/w PM 1 and 2 and checking the degree of atrophy of the nasal turbinates.
T or F: Advanced cases of Atrophic Rhinitis in which toxigenic strains of Pasteurella multocida B and C have inhibited osteoblastic activity and promoted osteoclastic resorption of the turbinate tissue; the ventral scrolls of the ventral nasal turbinates are the most commonly affected areas.
F
Strains A and D
All else is correct
A kitten with serous rhinitis, sneezing, and conjunctivitis would most likely be affected by what condition, and what is the etiology?
A. Feline viral rhinotracheitis; Feline Calicivirus
B. Feline viral rhinotracheitis; Feline herpesvirus-1
C. Feline Infectious Bronchitis; Feline Calicivirus
D. Feline AIDS; Feline Immunodeficiency Virus
B.
Inclusion Body Rhinitis is caused by _________ (give both names), and most commonly causes a transient rhinitis in pigs age ______ and occasionally a fatal systemic infection in pigs age _________. The Inclusion bodies are (intracytoplasmic/intranuclear) and (acidophilic/basophilic).
Suid Herpevirus-2/Porcine Cytomegalovirus
transient rhinitis- ages 3-5 weeks
fatal systemic- age less than 3 wks (sucklers)
Intranuclear, basophilic
A kitten with serous rhinitis, sneezing, conjunctivitis, as well as exhibiting signs of oral pain and the pictured lesion would most likely be affected by what etiology?
A. Feline Herpes virus-1
B. Feline Calicivirus
C. Feline Immunodeficiency Virus
D. Nocardia spp.
B. Calici virus
This causes almost clinically indistinguishable signs as Feline herpesvirus, except that it causes vesicular glossitis whereas FHV does not tend to cause vesicular or ulcerative lesions.
Bilaterally symmetrical ulcerative lesions that are usually located at the lateral borders and ventral surface of the tongue such as this are usually associated with what etiology?
A. Feline Calicivirus
B. Feline Herpesvirus-1
C. Uremia of renal failure
D. Combination of FCV and FHV-1
C.
A. Multifocal uremic glossitis
B. Multifocal suppurative glossitis
C. Multifocal ulcerative glossitis
D. Multifocal caliciviral glossitis
E. Caliciviral glossitis
C.
This is uremic glossitis
Dog, Southern U.S….EDx?
A. Granulomatous rhinitis
B. Mycotic rhinitis
C. Protozoal rhinitis
D. Neoplastic rhinitis
C.
Rhinosporidium seeberi is the protozoal etiology; found in warm areas such as TX, LA, etc. Can be seen in cattle as well.
Horse, Strangles. What is the most appropriate MDx?
A. Streptococcal lymphadenitis
B. Streptococcal eustachitis
C. Suppurative Eustachitis and/or lymphadenitis
D. Guttural pouch mycosis
D. Suppurative lymphangitis
C
Guttural pouch is ventral extension of the Eustacian tube.
6 month old quarter horse. No sneezing, coughing, nasal discharge or fever. No pain on palpation. What is the most likely Ddx?
A. Guttural pouch mycosis
B. Guttural pouch tympany
C. Strangles
D. Guttural pouch empyema
B
Horse. Has mucopurulent nasal discharge and the enlarged area is very painful on palpation. Most accurate MDx and etiology?
A. Acute suppurative lymphadenitis; Streptococcus equi
B. Chronic suppurative lymphadenitis; Actinomyces pyogenes.
C. Chronic suppurative lymphadenitis; Streptococcus equi
D. Chronic pyogranulomatous lymphadenitis; Nocardia spp.
C.
STRANGLES!!
A horse is referred to you who has chronic nasal discharge, swelling of the face/neck and fistulous tracts eruping on the surface of the skin. The horse also has facial paralysis and some trouble eating. You perform an endoscopy to get a better idea of the damage. This is what you see. What would you be most likely to find if you made a slide of this material?
A. Fungal hyphae and granulomatous inflammation; this is guttural pouch mycosis
B. Cartilaginous tissue (collagen) from the guttural pouch walls; this is advanced Strangles.
C. Calcium carbonate; these are guttural pouch stones.
D. Suppurative to possible pyogranulomatous exudate. These are “chondroids” of more chronic Strangles.
D.
Inspissated exudate.
What is the #1 Ddx??? Which vessel is involved? What is the most likely etiology?
Guttural pouch mycosis
Internal carotid artery
Aspergillus spp.
