Protozoa

  • Cutaneous infection may become a part of systemic infection
  • Mostly caused by Leishmania
  • Transmitted by sandflies
  • Occurs in dogs, cats and rodents (also humans)
  • Grossly in dog:
    • Generalised alopecia
    • Silvery white scales
    • Nodules and ulcers if more severe
    • Mainly on muzzle, ears and eyes where flies feed
  • Microscopically:
    • Hyperkeratosis, parakeratosis, crusts
    • Granulomatous nodules in dermis
    • Macrophages, some lymphocytes and plasma cells - periadnexal pattern, may affect sebaceous glands
    • Organisms may be found extra or intracellularly

Ticks

  • Local reaction depends on host hypersensitivity and tick's secretions
  • Grossly:
    • Focal erosions, erythema, crusted ulcers, sometimes alopecia and nodules
  • Microscopically:
    • Epidermal and dermal necrosis
    • Perivascular of diffuse inflammation and necrotic margins
    • Eosinophils, macrophages and lymphocytes in exudate
    • May form granulomas containing collagenous fibres and lymphoid follicles within dermis
