DERMATOLOGICAL DISORDERS
A careful history and complete physical examination of the dermatologic patient is essential. Establish the duration,anatomic region of the origin, and progression of the disease. Because certain disease have a heritable basis, make note of the breed. It is also important to define the age at which the disease was first apparent. In general, some [...]
DERMATOLOGICAL DISORDERS (Bacterial Infections) Abscesses and cellulitis
Abscesses and cellulitis
An abscess is a localized collection of purulent material in the dermis or subcutaneous tissues. Cellulitis is more extensive and often dissects through tissue layers.
Oral or epidermal flora are introduced by inoculation during penetration of the skin by teeth or claws. In dog bites, typical pathogens are staphylococcus aureas and Escherichia coli [...]
DERMATOLOGICAL DISORDERS (Bacterial Infections)deep-pyoderma-and-furunculosis
Deep pyoderma and furunculosis
Deep pyoderma is a bacterial infection of the dermis, which may result from the extension of infection through the walls of ruptured follicules(furunculosis).
Deep pyoderma and furunculosis are the result of a hair follicle rupture into the dermis with subsequent liberation of keratin. This liberated keratin acts as a foreign body within the [...]
DERMATOLOGICAL DISORDERS (Bacterial Infections) IMPETIGO ( Puppy pyoderma )
IMPETIGO ( Puppy pyoderma )
Impetigo is a sub corneal pustular disease of prepubertal dogs.
Impetigo is often associated with poor husbandary conditions. Staphylococus spp. Are usually isolated from sub corneal pustules.
Impetigo is not contagious and may occur for no apparent reason, In some younger dogs it may be associated with parasitism, poor nutrition, or infectious [...]
DERMATOLOGICAL DISORDERS (Bacterial Infections)
Superficial pyoderma
Superficial pyoderma is a bacterial infection of the superficial epidermis of the hair follicles.
The most common causes of superficial pyoderma are endocrinopathies, hypersensitivities, and ectoparasites. Staphylococcus intermedius is the most frequently isolated bacteria; S aureas may also be found.
Changes to the macro-environment lead to the development of conditions favoring the growth of Staphylococci. [...]
DERMATOLOGICAL DISORDERS (Bacterial Infections)
Pyotraumatic dermatitis ( acute moist dermatitis, hot spot ) pyotraumatic dermatitis involves acute inflammation and exudation of skin that has been damaged by rubbing, scratching, or licking. pyotraumatic dermatitis is very common in hot weather and especially in dogs with thick, long haircoats.
Underlying problems associated with pyotraumatic dermatitis include flea [...]
DERMATOLOGICAL DISORDERS (Bacterial Infections)
Skin fold pydoderma ( intertrigo )
Intertrigo is an inflammatory condition that occurs at sites of skin folds.
Anatomic defects at certain body sites predispose to intertrigo. Areas prone to skin fold dermatatis include the face, vulva, lips, body and tail fold.
Friction, abrasion,poor ventilation, and excess surface secretions lead to maceration and secondary inflammation with colonization [...]
DERMATOLOGICAL DISORDERS FUNGAL AND YEAST INFECTION Malassezia dermatitis Histopathologic examination
Histopathologic examination
In general, histopathologic examination has a low sensitivity in detecting Malassezia species, because the yeast are removed from the skin surface during processing. Consequently, the pathologist may not find any yeast in the processed biopsy sample. But if a few yeast are seen in the stratum corneum, reevaluate the patient for Malassezia dermatitis, [...]

DERMATOLOGICAL DISORDERS FUNGAL AND YEAST INFECTION Malassezia dermatitis Clinical presentation
Clinical presentation
Malassezia dermatitis can occur in dogs of any breed, age, or sex, although, as mentioned earlier, certain breeds seem predisposed.The incidence of Malassezia dermatitis may increase during the summer months, but the disease can occur at any time of year, especially in warmer climates. The association between Malassezia dermatitis and the summer [...]
