  • Candidia albicans is the most important species
    • C. tropicalis and C. pelliculosa are other important species
  • World wide distribution
  • Usually an endogenous mycoses
  • Immunocompromised animals may show symptoms
  • Usually lesions on mucous membranes and at mucocutaneous junctions
  • Many species have been implicated in bovine mastitis
  • C. albicans has been isolated in porcine stomach ulcers
  • C. rugosa has been implicated in pyometra in mares
  • Infection of the crop, oesophagus and mouth occur in poultry and other birds leading to sour crop
    • White-grey lesions in mouth which adhere loosly to the mucous membrane
    • Crop wall may be thickened
    • Crop wall may be covered by a yellow-white necrotic material
    • Underlying tissue is inflammed
  • Causes thrush in humans
  • Affects the tongue
  • C. albicans causes metritis and vaginitis in mares and genital candidiosis in stallions (and bulls)
  • Skin scrapings in 20% KOH for microscopy
  • Diphtheritic membranes, pus and fluids can be examined by Lactophenol Cotton Blue and stained by Gram or Methylene Blue stain
  • Gram positive, oval, thin-walled budding cells with hyphal fragments
  • Grow on Blood agar and Sabouraud's Dextrose agar producing soft, creamy colonies in 24-48 hours
  • Grossly:
    • Exudative, papular, pustular to ulcerative dermatitis
    • Stomatitis and otitis externa may develop
  • Microscopically:
    • Spongiotic neutrophilic pustular inflammation
    • Parakeratosis
    • Ulcerations
    • Superficial exudate containing organisms
