Study Notes
- Several fungi species are pathogenic to humans, causing superficial and cutaneous mycoses.
Hortae Werneckii
- This is the causative fungus of Tinea nigra.
- It is a superficial fungal infection.
- It is characterized by brown to black macules.
- It usually occurs on the palmar aspects of hands.
- Occasionally, it appears on the plantar and other surfaces of the skin.
Malassezia Furfur
- It is implicated as a causative agent of seborrhoeic dermatitis and dandruff.
Piedra Hortae
- This causes black piedra.
- Black piedra is a superficial fungal infection of the hair shaft.
- It forms hard black nodules on the shafts of the scalp, beard, moustache, and pubic hair.
- It is common in Central and South America and South-East Asia.
- Infections are usually localized to the scalp but may also be seen on hairs of the beard, moustache, and pubic hair.
- It mostly affects young adults, and epidemics in families have been reported following the sharing of combs and hairbrushes.
- Infected hairs generally have a number of hard black nodules on the shaft.
- Prevention and control include shaving or cutting the hairs short.
- Terbinafine 250 mg a day for 6 weeks may treat the infection.
Candida Species
- Cause candidiasis.
- Candidiasis is a primary or secondary mycotic infection.
- Involvement may be localized to the mouth, throat, skin, scalp, vagina, fingers, nails, bronchi, lungs, or the gastrointestinal tract.
- It can become systemic in the form of septicemia, endocarditis, and meningitis.
- In healthy individuals, Candida infections are usually due to impaired epithelial barrier functions.
- Candida infections usually remain superficial and respond readily to treatment.
- Infections occur in all age groups, but are most common in the newborn and the elderly.
