Superficial pyoderma describes '''cutaneous bacterial infection''' that is confined to the stratum corneum of the interfollicular skin and hair follicles. Normal [[Skin - Anatomy & Physiology|skin]] is colonised by a variety of resident bacterial and fungal organisms. They are not normally pathogenic and sometimes help prevent colonisation of pathogenic species through niche competition.

Potentially pathogenic coagulase-positive ''[[Staphylococcus species|Staphylococci]]'' colonise mucocutaneous junctions and mucosal reservoirs are an important source of infection.

It is an extremely common form of skin disease in the '''dog''', and the organism '''''Staphylococcus intermedius''''' predominates, but ''[[Staphylococcus aureus]]'', ''Staphylococcus pseudintermedius'' and other species may also be found.

Superficial pyoderma may be a '''primary condition''', but this is rare, and most recurrent pyodermas are '''secondary to underlying cutaneous and systemic disorders''' such as ectoparasites, [[:Category:Hypersensitivity|hypersensitivities]], endocrinopathies and keratinisation defects.

'''Horses and farm animals''' can also suffer from superficial pyoderma, such as [[Greasy Heel|Equine Pastern Folliculitis]], [[Dermatophilosis]], [[Ovine Fleece Rot]] and [[Greasy Pig Disease]].
