Demodicosis

26 Demodicosis







CLINICAL EXAMINATION


Demodicosis usually presents as focal or multifocal patches of alopecia with variable crusting, scaling and pruritus. Canine localized demodicosis (CLD) is usually defined as involving up to five individual patches of alopecia, while generalized disease (CGD) involves six or more patches, an entire body region, or presents as pododemodicosis. Squamous demodicosis is characterized by patches of alopecia, scaling, erythema, folliculitis and comedone formation. Pustular demodicosis is diagnosed when secondary bacterial infection is present, and is characterized by lesions of deep pyoderma and cellulitis. Most cases of CLD are squamous, whereas CGD may initially present as squamous, but frequently progresses to the pustular form of the disease. Exten-sive pustular demodicosis is a severe, potentially life-threatening systemic disease. Secondary infection with Staphylococcus intermedius is common and more rarely Pseudomonas aeruginosa or Proteus mirabilis may be involved. Peripheral lymphadenopathy is usually present in pustular demodicosis.
