Questions

1. Which of the following active ingredients is considered the most effective topical agent against Staphylococcus pseudintermedius? *

Acetic acid

Benzoyl peroxide

Boric acid

Chlorhexidine

2. Which of the following statements is false regarding the prudent use of oral antibiotics for the treatment of canine pyoderma? *

First-tier antibiotics can be selected empirically or based on the results of bacterial culture and sensitivity testing.

First-tier antibiotics include first-generation cephalosporins, clindamycin and trimethoprim/sulfamethoxazole.

Oral fluoroquinolones are always excellent empirical antibiotics for the treatment of methicillin-sensitive staphylococcal pyoderma.

Second-tier antibiotics (chloramphenicol, rifampin) are reserved for the treatment of methicillin-resistant staphylococcal infections.

3. The 2 most important differential diagnoses to rule out when diagnosing canine superficial pyoderma are: *

Dermatophytosis and demodicosis

Atopic dermatitis and contact allergy

Dermatomyositis and cutaneous vasculitis

Pemphigus foliaceus and discoid lupus erythematosus

4. Which of the following skin lesions is not characteristic of canine superficial pyoderma? *

Papule

Pustule

Lichenification

Crust

5. S. pseudintermedius is both a commensal (part of the normal cutaneous microflora) and an opportunistic pathogen. *

True

False

6. Even following complete resolution, pyoderma has the tendency to recur if the underlying disease is not properly addressed. *

True

False

7. Dermatophytosis, demodicosis and bacterial pyoderma can be clinically indistinguishable in dogs. *

True

False

8. Superficial pyoderma is also known as furunculosis. *

True

False

9. Which of the following statements is false regarding canine pyoderma. *

In short-haired breeds, it can present as multifocal (or “moth-eaten”) alopecia.

In short-haired breeds, it can present as elevated tufts of hair.

Skin biopsy/histopathological examination is often helpful.

Skin fold pyoderma is more common in brachycephalic breeds.

10. When is a bacterial culture and sensitivity test indicated? *

When there is a poor response to 2 weeks of appropriate empirical systemic antibiotic therapy.

When there is emergence of new lesions 2 weeks or more after initiation of such therapy.

When there is a recurrent skin infection with prior exposure to multiple antibiotic classes.

All of the above.
