to confirm if the organism is a bacteria or a yeast, we must perform ___
microscopic examination
– look for tapered edge and much bigger
are Candida albicans and Cryptococcus neoformans opportunistic fungi and can cause infection?
yes
are Filamentous fungi
Molds
a group of hyphae is called as _____
mycelium
a branching structure of molds that is for absorbing nutrients from media
hyphae

Fluffy/cottony/wooly/velvety or
sometimes powdery colonies
molds, Microscopically contains
hypha/hyphae (mukhang buntot yan sila )
a type of fungi wherein it Exhibits both yeast and mold form
Dimorphic Fungi
a type of fungi that is pathogenic
dimorphic fungi
dimorphic fungi’s form, whether in filamentous or yeast form, is based on temperature.
what is the required temperature for the filamentous/mold form of dimorphic fungi to form
25-30 * C
dimorphic fungi’s form whether it will be in filamentous or yeast form is based on temperature.
what is the required temperature for the yeast form of dimorphic fungi to form
35 - 37 * C
remember na yeast ang gamit sa pagbe-bake, diba mainit un? so ung mas malaking temperature ang YEAST form
example of dimorphic fungi
Blastomyces dermatitidis

Types of Hyphae
- Based on Location in Culture Media
- Based on pigmentation
hyphae Based on Location in Culture Media
aerial hyphae
vegetative hyphae
hyphae Based on Pigmentation
- Hyaline Hyphae/Moniliaceous
- Dematiaceous Hyphae
Forms of Hyphae
- Septate Hyphae (molds)
- Aseptate Hyphae (molds)
- Pseudohyphae (yeast cells)
Aseptate Hyphae is also called as
coenocytic hyphae
the fuzzy appearance of colonies with hyphae is because of
aerial mycelia/hyphae that has spores
a hyphae that anchors the colonies in the media as well as to absorb the nutrients
vegetative hyphae
this kind of hyphae according to pigmentation is clear unless stained
Hyaline Hyphae/Moniliaceous
this kind of hyphae according to pigmentation has melanin content making the hyphae or fungi appears darker
Dematiaceous Hyphae (brown or black)
can we stain our Dematiaceous Hyphae be stained using Lacto-phenol cotton blue (LPCB)
nope, it will not penetrate the hyphae to stain.
Forms of Hyphae
- Septate Hyphae
- Aseptate Hyphae
- Pseudohyphae
this form of hyphae has cross walls
septate hyphae
this form of hyphae has no cross walls
Aseptate Hyphae
this form of hyphae are yeast cells that elongates due to prolong incubation
pseudohyphae

2 stages of sexual reprodiuction
plasmogamy
karyogamy
plasmogamy is a fusion of
cells
karyogamy is a fusion of
nucleus

arthrospores
arthrospores
fungi examples
Trichosporon

a rounding of hyphae at the top or end is called as
terminal chlamydospores
a rounding of hyphae at the middle is called as
intercalary Chlamydospores
a rounding of hyphae at the peripheral is called as
sessile Chlamydospores
example of fungi that has Chlamydospores

fungi that uses Conidiospores as reproduction
Conidiospores
aspergillus
a type of asexual reproduction wherein a budding from the mother cells occur
