Module II Flashcards
(22 cards)
What common factors affect the skin barrier?
Parasites, bacteria, fungi/yeast, allergies, metabolic changes, keratinization disorders
Seborrheic animals:
Have greatly increased numbers of bacteria on their skin surface. Alteration of the lipid layer/skin barrier causes animals to itch
Follicular inflammation is caused by:
Common causes are demodicosis (demodectic mange) and dermatophytosis (fungal infections)
Primary infections:
Occur in otherwise healthy skin, with no underlying cause.
Secondary Infections:
Most common. Result from some underlying cause like allergies, keratinization or follicular disorders
Pyo stands for:
Pus
What percent of dogs and cats presented to a general practice has some type of skin condition?
20-30%
What part of the skin does surface pyoderma affect?
The surface of the skin
Superficial pyoderma
Bacteria invades the epidermis and hair follicles. Invasion of follicles causes folliculitis
Alopecia
Hair loss
Deep Pyoderma
Breaks down through hair follicles to involve the dermis. Is a serious bacterial infection.
Do deep pyoderma’s appear spontaneously?
No. There is always a cause of infection – usually they appear as a continuation of a superficial infection or folliculitis
Staphlyococcus pseudointermedius
Causes over 90% of canine bacterial pyoderma (most common bacteria)
Biofilm:
Communities of microorganisms immersed within a self-produced substance of proteins and fats which are firmly attached to a surface
Atopic dermatitis:
A genetically predisposed inflammatory and pruritic or itchy skin disease with characteristic clinical signs associated with the activation of specific antibodies to fight environmental allergens.
Is there a cure for Atopic Dermatitis?
No. This is a disease that will need to be managed over the life of the pet.
Multifactorial Disease
More than one factor is involved in the development of the condition
Keratinization Disorders
Keratinization defects are those that alter the skin’s surface appearance. It looks and feels scaly. Commonly referred to at seborrhea or seborrheic
What causes secondary keratinization disorders?
Ectoparasites, allergies, metabolic disorders, pyoderma, autoimmune disease, fungal infections and/or cancer
Keratinization
Process where epidermal cells are constantly being renewed and replaced by new cells
Keratolytic
Agent that aids in the softening and shedding of the tough outer layer of the skin
Keratoplastic:
Agent that improves the keratinization process. Helps normalize skin turnover
