Fungi - Fungal diseases
6 important questions on Fungi - Fungal diseases
Properties of superficial mycoses:
- Fungi do not cause a host cellular response
- 'infections' do not cause pathology
- patients only gets concerned of cosmetic reasons and not of discomfort
- generally affects stratum corneum (hoornlaag) of skin and hair
Properties of athelete's foot:
several different fungi and transmitted in moist environments (with people with bare feet)
Properties of subcutaneous mycoses:
- Infections involve deeper layers of the dermis and subcutaneous tissues
- formation of lesions (damage)
- remain localized or spreads directly via lymphatic system
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Properties of systemic mycoses:
True systemic mycoses:
- inhalation -> pulmonary infection -> dissemination
- caused by fungi existing in nature
- geographic distribution varies
- no evidence of transmission among humans and animals
- dimorphism: can have different shapes depending on environmental factors -> can grow in filamentous or yeast form
Opportunistic systemic mycoses
- any fungus in nature can cause opportunistic mycoses
- candidiasis causes nosocomial infections (=hospital infections)
- aspergillosis is the most deadly mold
- cryptococcosis
- zygomycosis
What causes higher susceptibility for mycoses?
- HIV
- malignancy and chemotherapy
- organ and bone marrow transplantation
- Neutropenia, corticosteroid therapy, immunosuppression, graft-versus-host disease (donor cells attack body)
Properties of saprolegnia (cotton wool)
need wet environments to complete its lifecycle, fatal if not treated
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
