1 injection of cefovecin

No additional antimicrobial drugs

2. Methicillin-resistant staphylococci are generally considered resistant to only: *

Methicillin

Methicillin and cephalosporins

All types of penicillin

All beta-lactam antibiotics

3. Which species of bacteria is most often associated with pyoderma in dogs? *

Staphylococcus intermedius

S. aureus

S. pseudintermedius

S. schleiferi

4. Which of the following statements best describes staphylococci? *

They are only rarely part of the cutaneous microbiota of mammals

Several species can be both harmless commensals and opportunistic pathogens

They are gram-negative

They are rod-shaped

5. A dog that presents with a superficial pyoderma with a methicillin-resistant S. pseudintermedius most likely acquired that organism: *

Through contact with a dog with the same organism

When its own bacterial population mutated spontaneously

When its own bacterial population mutated during antibiotic therapy

When its own bacterial population mutated during antimicrobial shampoo therapy

6. Which of the following skin lesions provides the best sample for bacterial culture? *

A papule

A pustule

A crust

A draining tract

7. The most common primary disease leading to pyoderma in dogs is: *

Cushing’s disease

Malassezia dermatitis

8. The following antibiotic is appropriate for first-line therapy of superficial pyoderma when topical therapy is not possible: *

Clindamycin

9. Which of the following is not a typical indication for a bacterial culture in a dog with pyoderma? *

Pyoderma in a puppy

Suspected zoonotic infection

Severe deep pyoderma

10. What should we tell clients after isolating a methicillin-resistant S. pseudintermedius from their dog’s skin infection? *

This organism responds poorly to topical therapy with chlorhexidine

There is some risk of zoonotic transmission, but it is low

A longer course of oral antibiotics is usually necessary

Their dog should be re-homed
