Fungi Introduction
General features
Ecology
Widely distributed
Ubiquitous
Main roles
Decomposers
symbionts
parasites
Mycosis
Disease caused by a Fungus
Mycotoxicosis
A disease caused by the toxins produced bt a fungus
Mycetm
Biology
Eukaryotic
Aerobes
Non- photosynthetic
Absorb nutrients from their environments
Non- motile
Resistant to Anti-bacterial drugs
Major component of PM
Ergosterol
Chitin
Aerial Hyphae

How Fungi cause disease
Tissue invasion
Mycosis
Superficial or cutaneous
Dermatophytes
Dermatophytosis
Ringworm
Groups
Geophilic
Zoophillic
Anthropophilic
Subcutaneous
Systemic Mycosis
innovation of internal organs
Highly virulent
Blastomycosis
Coccidiomycosis
Histomycosis
All Dimorphic
Most mycoses are caused by opportunistic Fungi
Predisposing factors
Debilitated animals
Prolonged antibiotic treatment
Immunosuppressive therapy
Exposure to spores
Aspergillus genus is very common
Yeast infections
Malassezia genus
Lipophillic
Cryptococcus genus
Toxin production
Mycotoxicosis
Toxic effects
immunosuppression
Teratogenesis
Embryo/ Foetal defects
Carcinogenic agents
Aflatoxin genus
Target organ: Liver
Hepatic lesions
Ergotism
Gangrenous lesions
Convulsions
Induction of hypersensitivity
Allergic reaction
