|
|
Superficial Fungal Infections |
involve outer layer epidermis; cosmetic only
"she's so superficial-all about what she looks like on the outer layer" |
|
|
Subcutaneous Fungal Infections |
invade traumatized skin |
|
|
Systemic Fungal Infections |
occur from inhalation |
|
|
Major Cutaneous Mycosis |
occur in the non-living epidermal tissue (stratum corneum)
*these are dermatophytoses |
|
|
Tinea "Ringworm" |
is a type of dermatophytoses |
|
|
Causitive Agents for Ringworm |

|
Major Cutaneous Mycoses |
invade just beneath the skin (traumatized skin allows entry) |
|
|
Mycetoma "Madura Foot" Causitive Agents |
1. Pseudallescheria 2. Madurella |
|
|
Mycetoma |
large fungal tumor-like structures of limbs
systemic when spreads to bones or muscles |
|
|
Opportunistic Mycoses |
takes advantage of immunocomprimised host |
|
|
3 major human pathogens |
1. candida-yeast 2. pneumocystis-yeast 3. aspergillus-filamentous fungus |
|
|
Candidiasis Caustative Agent |
Candida albicans |
|
|
Candidiasis |
normal part of the floral in the oral cavity, genitalia, and large intestine
on the skin of approx. 20% of humans |
|
|
Candidiasis |
pregnancy, drug therapy, immunodeficiency, or trauma allow all the pathogen to flourish |
|
|
Thrush |
White patchy appearance in oral cavity that aids patients develop with candidiasis |
|
|
Vulvovaginal |
"yeasties"- female genital region, ulceration and a white/yellow discharge develops with candidiasis |
|
|
PCP (pneumocystis carinii-Pneumonia)
Causative Agent |
pneumocycstis carinii |
|
|
PCP |
primary opportunistic infection in aids patients
forms secretions in the lungs and can be rapidly fatal |
|
|
Aspergillosis causative agent |
Aspergillus niger |
|
|
Aspergillosis |
spores of this mold are found in high concentrations in dust
inhaled spores can cause fungus balls in the lungs |
|
|
Amphotericin B |
agent to treat oral and vaginal infections |
|
|
Miconazole |
agent to treat vaginal infections |
|
|
Flucystosine |
Agent to treat systemic mycoses |
|
|
Challenge |
fungal cells are eukaryotic
agents are toxic to the host cells as well as fungal cells
fungal cells have chitin so that is the target |
|
|
Cutaneous fungal infections |
infections restricted to the non-living areas of the skin |
