DERMATOPHYTES MODE OF TRANSMISSION
ANTHROPOPHILIC ZOOPHILIC GEOPHILIC
34
DERMATOPHYTES MODE OF TRANSMISSION - Associated with animals
ZOOPHILIC
35
DERMATOPHYTES MODE OF TRANSMISSION - associated with humans only; person-person transmission through contaminated objects ( comb, hat etc.)
ANTHROPOPHILIC
35
DERMATOPHYTES MODE OF TRANSMISSION - Usually found in soil; transmitted to humans by direct exposure
GEOPHILIC
36
Spores produced in a chain at the tip of a conidiosphore
CONIDIOSPORES
37
Elongated flask shaped projection rising from the vesicle
PHIALIDES (STERIGMA/STERIGMATA)
38
ASPERGILLUS PENICILLIUM PHIALOPHORA EXOPHIALA
CONIDIOSPORES
39
- if spore is enclosed in a sac, sporangiospores - septated hyphae which bears terminal conidiosphore
ASPERGILLUS
40
- BRUSH-LIKE conidiophore - septated hyphae with conidiophore that exhibit branching to form metulae
PENICILLIUM
41
- Septated hyphae with FLASK-SHAPED phialides with CUP-SHAPED COLLARETTES with conidiospores
PHIALOPHORA
42
- LONG CONIDIOPHORE at tapering end - no phialides
EXOPHIALA
43
- Asexual spores that contain a SAC/SPORANGIUM - Unique among fungi can be NONSEPTATED/COENOCYTIC
SPORANGIOSPORES
44
ZYGOMYCETES:
MUCOR,RHIZOPUS,ABSIDIA
45
- Nonseptated hyphae with NO RHIZOIDS
mucor
46
- Nonseptated hyphae with RHIZOIDS
RHIZOPUS
47
SEXUAL REPRODUCTION: 3 phases:
PLASMOGAMY KARYOGAMY MEIOSIS
48
Fusion of haploid fungi resulting to one organism with two nuclei
PLASMOGAMY
49
Fusion of nuclei to form diploid organism
KARYOGAMY
50
- Diploid nucleus becomes haploid
MEIOSIS
51
Produce DIKARYOTIC FUNGI
PLASMOGAMY
52
Produce DIPLOID FUNGUS
KARYOGAMY
53
Will DIVIDE NUCLEI into 2 producing HAPLOID FUNGI
MEIOSIS
54
- Clusters of four or eight spores within a sac called ASCUS
ASCOSPORES
55
Fusion of 2 identical cells arising from fused hyphae
ZYGOSPORES
56
CLINICALLY IMPORTANT MEMBERS OF ZYGOMYCOTA:
Rhizopus Mucor Absidia
57
Contained in a CLUB-SHAPED BASIDIUM - MUSHROOMS
BASIDIOSPORES
58
These fungi do not show any sexual stage
IMPERFECT FUNGI (DEUTEROMYCETES)
