Define Mycology
Brunch of biology concerned = study of fungi.
Define Medical Mycology
A branch of mycology (brunch, study of fungi) concerned in HUMANS.
What are 4 types of fungal disease
- Superficial
- Cutaneous
- Subcutaneous
- Systemic
- Opportunistic
Where is Anatomic locations of the 4 types of fungal diseases?
- Superficial = Hair shaft, dead layer of skin
- Cutaneous = Epidermis, hair, nails
- Subcutaneous = Dermis, subcutis
- Systemic = Internal Organs
- Opportunistic = Internal Organs
The representative disease ‘Blastomycosis’ is caused by which type of fungal disease?
Systemic
What Causative organisms can cause infection in the virginal tract?
Candida + Aspergillus organisms
List the Characteristics of Fungal Cell wall.

- Multicellular
What are the two main structure of Moulds?
Hyphae + Mycelium
Name 2 example of non-pathogenic organism of Yeasts.
- Saccharomyces, bakers’ yeast -non-pathogenic.
- Cryptococcus Neoformans.
What are the two types of human fungal pathogens determines by types of disease?
TRUE (PRIMARY) PATHOGENS
OPPORTUNISTICS PATHOGENS
How does fungal/Yeast pathogens divides?
Asexual Reproduction + BUDDING
Yeast cell divides by budding through N…F…
Nuclear Fission
What is Dimorphic Fungi?
A type of Yeast - Forms - Filaments = Dimorphism.
List the types of clinical samples can be collected to further examine, specific pathogen?
- Sputum,
- pus,
- blood,
- spinal fluid,
- bronchioalveolar lavage,
- urine, tissue biopsy or skin scrapping
What are the diagnoses of fungal infection?
- Skin test
- serology,
- microscopic examination of tissue samples and results of culture from clinical samples.
List the symptoms of ‘Chronic pulmonary Blastomycosis’ (TRUE (PRIMARY) PATHOGEN DHIMORPHIC)

- Haemoptysis
- Night sweating
True or False: ‘Fungi is more commonly infects humans then plants’
False: Fungi commonly infects plants but closer to humans.
