Methicillin resistance of staphylococci isolated from the skin of dogs with pyoderma.

Objective: To determine the methicillin-resistant profile of staphylococcal isolates from the skin of dogs with pyoderma.

Animals: 90 dogs with pyoderma.

Procedure: Staphylococci isolated from dogs with pyoderma were tested for susceptibility to methicillin by use of a standard disk diffusion test with oxacillin disks.

Effects of short-term trimethoprim-sulfamethoxazole administration on thyroid function in dogs.

Objective: To determine how rapidly trimethoprim-sulfamethoxazole affects serum total thyroxine (T4) and thyroid-stimulating hormone (TSH) concentrations in euthyroid dogs and how quickly hormone concentrations return to reference values following discontinuation of administration.

Design: Prospective study.

Animals: 7 healthy euthyroid dogs.
