title: A study of skin diseases in dogs and cats. VI. Microflora of the major canine pyodermas.
abstract: From 40 dogs with pyoderma swabs from areas with representative lesions were examined bacteriologically. Staph. aureus was found in 98% of the areas, beta-hemolytic streptococci in 30%, and Gram-negative organisms, mainly Proteus spp., in 30% (Table I). Pure infection with Staph. aureus was found in 55% of the areas. Staph. aureus and beta-hemolytic streptococci were found in 15%, Staph. aureus and Gram-negative organisms in 15%, Staph. aureaus and beta-hemolytic streptococci as well as Gram-negative organisms in 13%, and beta-hemolytic streptococci and Gram-negative organisms in 3% (Table II). Compared to normal and eczematous skin areas, Staph. aureus was found more often, and in greater numbers, in areas with pyoderma, whereas micrococci, alpha-hemolytic streptococci, and Acinetobacter spp. were rarer. Gram-negative organisms such as Proteus spp., E. coli, and Pseudomonas spp. were found with equal frequency in eczema and pyoderma, while beta-hemolytic streptococci were almost exclusively associated with suppurative lesions (Tables IV and V).
