Abstract
PLEASE NOTE A NEW 4TH EDITION HAS BEEN PUBLISHED AND IS AVAILABLE IN THE LIBRARY AND IN PRINT
Ninety percent of canine pyodermas are caused by Staphyloccoccus pseudintermedius (previously called S. intermedius), a Gram-positive, facultative aerobic, beta-haemolytic, coagulase-producing bacterium. Other coagulase-positive and coagulase-negative staphylococci (S. schleiferi schleiferi, S. chleiferi coagulans, S. aureus and epidermis) and other Gram-positive and Gram-negative bacteria, such as Pseudomonas aeruginosa or Proteus spp. and Escherichia coli, may be isolated occasionally. In cats, S. aureus and S. pseudintermedius are considered the main causes of feline pyoderma, excluding abscesses. This chapter discusses Aetiology and pathogenesis; Differential diagnosis; Clinical approach; Diagnostic tests; and Treatment.
