(1) Intro to Mycology Flashcards
GENERAL CHARACTERISTICS OF FUNGI
what is the branch of microbiology that deals with the study of fungi
MYCOLOGY
GENERAL CHARACTERISTICS OF FUNGI
Fungi can be characterized as?
Good and Bad Fungi
Good or Bad Fungi
edible mushrooms and Saccharomyces cerevisiae which are used in making alcohol in beer and wine, or in making bread
Good Fungi
GENERAL CHARACTERISTICS OF FUNGI
what fungi are used in making alcohol in beer and winde or in making bread
edible mushrooms and
Saccharomyces cerevisiae
Good or Bad fungus
this fungi causes disease
Bad Fungi
GENERAL CHARACTERISTICS OF FUNGI
Enumerate the characteristic of fungi to me please
- Eukaryotic
- Aerobic or Facultatively anaerobic
- Heterotrophiv
- Aclorophyllous
- Monomorphic or Dimorphic
GENERAL CHARACTERISTICS OF FUNGI
give the 2 morphology of fungi
- Monomorphic
- Dimorphic
GENERAL CHARACTERISTICS OF FUNGI
What is the morphology of a fungi if it exist in one form?
Monomorphic
GENERAL CHARACTERISTICS OF FUNGI
What is the morphology of a fungi if it exist in 2 form?
dimorphic
GENERAL CHARACTERISTICS OF FUNGI
what is the MAIN BASIS for diifferentiation of fungi
Temperature where fungi can incubate or grow
GENERAL CHARACTERISTICS OF FUNGI
what are the 2 distinct structure of fungi that can be seen under the microscope
Hyphae and Spore
GENERAL CHARACTERISTICS OF FUNGI
it contains a true nucleus wth an enclosed nuclear embrane
Eukaryotic
GENERAL CHARACTERISTICS OF FUNGI
requires oxygen to grow. However, most medicallyimportant fungi are facultatively anaerobic, hence, they
are flexible and can grow with or without oxygen.
Aerobic or facultatively anaerobic
GENERAL CHARACTERISTICS OF FUNGI
They have no chlorophjyl, this the characteristic that set them apart from a plant
Achlorophyllousa
Fungal cell consists of an?
Enclosed nucleus
What is the most differentiating content of the fungal cell wall?
presence of Chitin in the cell wall
What is one of the feature that the cytoplasmic membrane of the fungal cell wall consist?
Ergosterol
this is the pinaka important okie
Fungi or Bacteria
Cell Type: Prokaryotic
Bacteria
Fungi is eukaryotic
Fungi or Bacteria
the cell membrane have sterols such as ERGOSTEROL
Fungi
Bacteria - Sterols absent,
except in Mycoplasma
Fungi or Bacteria
cell wall contents: lucans, mannans, and CHITIN
Fungi
bactera - Peptidoglycan
Fungi or Bacteria
Produces a wide variety of sexual and asexual reproductive spores
Fungi
Bacteria - Endospores are not for reproduction; some asexual spores
Fungi or Bacteria
Metabolism: Heterotrophic, chemoautotrophic, photoautotrophic, aerobic, facultative aerobic, anaerobic
Bacteria
Fungi - Limited to heterotrophic, facultative
anaerobic
Fungi or Bacteria
Often sensitive to polyenes,
imidazole, and griseofulvin
clue: yuck a PIG
Fungi
Bacteria - Often sensitive to penicillin, tetracycline, and aminoglycosides
Fungi morphology
morphology of fungi are differentiated by comparison of?
Temperature (incubation) where the fungi grows
Fungi morphology
Exist at room temperature at 25 ‘C to 30 ‘C
MOLDS or FILAMENTOUS
Fungi morphology
Exists at body temperature at 37 ‘C which is why it is the type known to cause fungal infections and other diseases in humans
YEAST or TISSUE
Fungi morphology
Best grown at Sabourauds Dextrose Agar (SDA) wherein it forms dry colonies
MOLDS or FILAMENTOUS
Fungi morphology
Best grown at Brain Heart Infusion Agar**(BHIA) **wherein it forms moist colonies
YEAST or TISSUE
Fungi morphology
Multicellular
MOLDS or FILAMENTOUS
Fungi morphology
Unicellular
YEAST or TISSUE
what if the fungi exists in two morphologies, what are they called?
Dimorphism
btw its not a what if, they exist
if a dimoprbihc fungi were to be exposed from a BODY TEMP to a ROOM TEMP, what can be the shift
yeast to mold
if a dimoprbihc fungi were to be exposed from a RT to a BODY TEMP, what can be the shift
mold to yeast
Structures of Fungi
Branching, hair-like or thread-like, tubular filaments of fungi observed under the microscope or by naked eye through culture in agar
MYCELIUM or HYPHAE
Structures of Fungi
What are the 2 types of Hyphae?
Aerial and Vegetative
Structures of Fungi
what type of hyphae holds the spores or the conidia and observed on the surface of the agar
Aerial
Structures of Fungi
what type of hypae absorbs nutrients and is observe sub-surface of the agar
Vegetative
Structures of Fungi
TOF
hypae can be reporductive or non-reproductive
F
(reproductive, wrong spell)
enumerate the reproductive hyphae
- Septate
- Aseptate or Coenocytic
- Hyaline
- Dematiaceous
Reproductive Hyphae
- Seen under the microscope with CROSS WALLS
- Also known as conidiophore
A suffix of -phore refers to hyphae.
Septate
