	Comparison between fungi and bacteria	T/F
a	Bacteria cell wall is made up glucans, manans and chitin	F
b	Fungi is a type of prokaryote	F
c	Fungi are sensitive to polyenes, azoles and griseofulvin	T
d	Capsules are present in some fungi such as Klebsiella pnuemoniae	F
e	Sterols are present in the cell membrane of fungi	T

1	Which statement regarding asexual spores are correct ?	T/F
a	Arthrospores are formed by fragmentation of a septate hypha into single, thickened cell	T
b	Candida albicans is an example of conidiospores	F
c	Sporangiospores is a thick walled spores	F
d	Sporangiospores are formed within a sac called sporangium	T
e	Aspergillus flavus is an example of conidiospores	T

1	Regarding sexual spores,	T/F
a	Formed by aerial mycelium	F
b	Result from fusion of 2 nuclei of opposing mating types	T
c	It consists of 3 phases which are plasmogamy, karyogamy and by meiosis	T
d	Plasmogamy occurs when donor and recipient nuclei fuse to form a diploid zygote nuclei	F
e	By meiosis, haploid nuclei gives rise to diploid nucleus	F

1	Regarding medically important phyla of fungi,	T/F
a	Deuteromycota is known as “holding category”	T
b	Rhizopus is an example of zygomycete	T
c	The life cycle of rhizopus finished when the zygospore forms	F
d	For Ascomycota, spores are produced in a saclike structure called ascus	T
e	Basidiospores are formed externally on a base pedestal called basidium	T

	Determine whether these statements about laboratory diagnosis of fungi are true or false	T/F
a	Preparation of direct examination of clinical specimens include KOH, India Ink and Calcoflour White	T
b	Germ tube test is a rapid “presumptive test” for Aspergillus flavus	F
c	In germ tube test, a light inoculum of cultured yeast is incubated in bovine serum for 24 hours at 27ºC	F
d	Carbohydrate assimilation test is used for definite speciation of Candida and few other fungi	T
e	Rapid urease test is considered positive when the red slope turns yellow	F
