Fungi-nail

The biochemical basis for its action in fungi has not been totally elucidated. Giclopiroxolamine [41621 -49-2] is used mainly in the treatment of mycoses of the skin and nails. [Pg.254]

All three of these are dermatophytes, i.e. filamentous fungi which can utilize keratin for their nutrition. Keratin is the chief protein in skin, hair and nail. Hence, all of these organisms are responsible for superficial mycoses in mammals. It is often stated that dermatophytes are the only fungi to have evolved which rely upon infection for then-own survival. This mistaken belief results from a view which is too human-centred and neglects, for example, the presence of symbiotic fungi in the stomachs of ruminants. [Pg.50]

Proteins of cat saliva dry and flake off as dander, which contains major indoor allergens linked to asthma. Dogs, horses, cattle, and other animals also provide several allergens,454 some of which are lipocalins (Box 21-A) 455 Other close-to-home allergens are provided by fungi that live on skin or nails.456... [Pg.1863]

Dermatophyte is the term applied to a range of fungi capable of colonizing the skin, nails or hair. The principal dermatophytic fungi are Trichophyton, Microsporum and Epidermophyton species. The most commonly encountered dermatophytic infections are athlete s foot (infection of the foot) and ringworm (fungal infection of the scalp or skin). [Pg.47]

The dermatophytes are a group of keratinophilic fungi that can metabolize keratin —the principal protein in skin, nails and hair. Tinea capitis is defined as the infection of the hair and scalp with a dermatophyte, usually Microsporum canis or Trichophyton violaceum. In Europe and North Africa T. violaceum may be responsible for approximately 60% of cases of tinea capitis. This condition is characterized by a mild scaling and loss of hair and in some cases it may be contagious. Tinea corporis is... [Pg.56]

Systemic infections cansed by fungi are cryptococcus meningitis or endocardites, pulmonary and cerebral aspergilloses, blastomycoses, histoplamosis, coccidiomycosis, and paracoccidiomycosis. Superficial infections are classified into dermatomycosis (infections of the skin, hair, and nails) and candidiasis (infections with yeast that affects mncons membranes of the mouth, vagina, or skin). [Pg.444]

Onychomycosis is infection of the nails of the fingers or toes caused by dermatophytes (fungi that live on the outer keratinous layer of the skin), yeasts or moulds. [Pg.57]

Chitin is derived from the Greek word chiton, which means a coat of nail. It is the major component of the exoskeleton of invertebrates, crustaceans, insects, and the cell wall of fungi and yeast (Knorr, 1984 Lower, 1984 Tan et al., 1996) in which chitin acts as a supportive and protective component. Chitin is the second most plentiful natural polymer on earth after cellulose (Brzeski, 1987 Ornum, 1992). At least 10 gigatons (1 x 1013 kg) of chitin... [Pg.93]

Dermatophytes are fungi causing infections of skin, hair, and nails (3). The dermatophytes obtain nutrients from attacking the cross-linked structural protein keratin, which other fungi cannot use as a food source. Dermatophytic infections, known as tinea, are caused by various species of three genera Trichophyton, Microsporum, and Epidermophyton) and are named for the site of infection rather than for the causative organism. Tinea capitis is a... [Pg.1718]
