superficial spreading pyoderma

In superficial spreading pyoderma, nummular areas of alopecia and erythema are centrifugally expanding, with epidermal collarettes and crusts. 176-7). Focal area of alopecia caused by folliculitis in an allergic dog. Although conventional antigens require recognition by all five elements of the T-cell-receptor complex, superantigens require only the variable region of the β-chain. Acne vulgaris, drug-induced acneiform eruptions, rosacea, hidradenitis suppurativa, acne necrotica of the scalp, and eosinophilic folliculitis of HIV disease must be distinguished from infectious folliculitis as well. Pyoderma is a cutaneous infection with pyogenic (pus-forming) bacteria. • Shetland sheep dogs often develop large superficial spreading areas of alopecia, erythema, and scaling. Systemic antibiotics (minimum 3–4 weeks) should be administered and continued 1 week beyond complete clinical and cytologic resolution (see Box 3-2). Symptoms : It is mostly associated with hematological conditions . Deep pyoderma is defined by infection deep within the hair follicle, with or without follicular rupture (furunculosis) (Figure 84-2) German shepherd dogs seem prone to a more severe and extensive form of deep pyoderma.3 Other examples include pedal folliculitis and furunculosis, pressure-point pyoderma, pyotraumatic folliculitis and furunculosis, and muzzle folliculitis and furunculosis (“canine acne”). The existence of a real bacterial allergy is presumed and debatable. The nonbullous type of impetigo accounts for more than 70% of cases of this form of pyoderma. This large focal area of alopecia, erythema, and hyperpigmentation with central regrowth of hair is often misdiagnosed as dermatophytosis. Nasal carriage of S. aureus appears to be a major risk factor for wound infection after cardiac surgery, resulting in higher mortality rates and longer postoperative stays.3 The rate of S. aureus bacteremia is also higher in nasal carriers of S. aureus.4 Good nursery technique, careful handling of patients, strict hand-washing procedures, and isolation of patients with open draining staphylococcal infections are important in the reduction of transmission of Staphylococci. These lesions are often associated to intact but transient follicular pustules. Deep Canine Pyoderma refers to deep inflammation on the hair follicle, and the possible presence of out types of skin conditions such as canine acne. They may activate B cells, leading to high levels of immunoglobulin E (IgE) or autoantibodies.8 Also, there is evidence that superantigens selectively induce cutaneous lymphocyte-associated antigen on T cells, thereby “homing” them to the skin.8, There are several other mechanisms by which S. aureus evades immune clearance. Two clinical patterns of impetigo are recognized: (1) bullous and (2) nonbullous. Pyodermas are infections in the epidermis, just below the stratum corneum or in hair follicles. Papular rash with epidermal collarettes typical of folliculitis in an allergic dog. If the hair follicle ruptures, the infection is released into the surrounding tissue leading to swelling and sinus formation. INDICATIONS OF PYODERMA IN YOUR DOG. The underlying cause must be identified and controlled. Superficial pyoderma rarely is a primary disease, but rather is a symptom of another skin problem. Superficial spreading pyoderma Superficial spreading pyoderma is characterised by large, spreading and coalescing epidermal collarettes, erythema and exfoliation (Fig 5). This moth-eaten texture of the hair coat is a characteristic finding in short-coated breeds with pyoderma. Treatment of anterior nares and wounds with mupirocin ointment has been shown to decrease S. aureus colonization but in one study did not decrease the rate of transmission to a roommate in a long-term care facility.10 Although there are many other reports of the use of topical mupirocin to reduce colonization of MRSA and methicillin-sensitive S. aureus, indiscriminate use of topical mupirocin must be avoided because significant mupirocin resistance has already emerged.
