Candidosis

Cryptococcosis

Geotrichosis

Malassezia pachydermidis

  • Caused by Malassezia pachydermatis
  • Yeast, normally present in external ear canal and skin
  • Clinical disease may cause yeast to proliferate and cause infection
  • Grossly:
    • Regional lesions: muzzle, ears, interdigital, perianal
    • Or generalised disease
    • Erythematous, hyperpigmented, lichenified and scaly lesions with alopecia
  • Microscopically:

Rhodotorula

  • Rhodotorula minuta and R. rubra
  • Canine ear infections
  • Equine uterus
  • Seldom seen in animal infections

Torulopsis glabrata

  • Commensal in animals and is found in the soil
  • Implicated in cases of:
    • Pyelonephritis, pneumonia, septicaemia and meningitis (humans)
    • Mastitis and abortion in cattle
    • Systemic infection of monkeys and dogs

Trichosporonosis

  • Found in soil
  • Deuteromycetes yeast
  • Trichosporonosis beigelii
    • Implicated in feline nasal granuloma, skin infections in horses and monkeys, mastitis in cattle and sheep and in feline bladder infections
  • T. capitum implicated in bovine mastitis
