presentation. because the infection is secondary, the area affected will vary

depending on the underlying cause.

in cases of trauma or laceration, lesions tend to appear in the area of the

injury. when the underlying causes are systemic, lesions tend to

predominate in the trunk area, and may spread to other sites, particularly incases involving pruritic conditions. in chronic cases, most of the skin may

be involved.

the initial characteristic sign of superficial bacterial folliculitis is an

inflammatory papule (fig. 15) or pustule (fig. 16) that usually covers a

follicle. in a recent study in which a model of superficial canine pyoderma

was developed, the authors reported that papules can appear 24 hours after

experimental infection, and can rapidly progress to pustules and

subsequently more severe lesions in 48 to 96 hours. pustules progress to

crusts and epidermal collarettes (fig. 17), and in some cases purulent

exudate is observed 1 week after inoculation.

epidermal collarettes may not be present in all forms of superficial bacterial folliculitis. recent findings suggest that epidermal collaretes in exfoliative superficial pyoderma may have unique clinical and histological features, which differ from those of collaretes in impetigo and superficial

bacterial folliculitis. it is possible that as-yet-unidentified toxins secreted by pseudintermedius can cause detachment or separation of the epidermis,

giving rise to collarettes
