asexual spore produced by segmentation of hyphae
arthroconidia
skin plant
dermatophytes
most common dermatophytes
Trichophyton
T. rubrum
T. interdigitale
asexual large multinucleate spores formed by vegetative reproduction
macroconidia
asexual small spores produced by vegetative reproduction
microconidia
long filamentous fungus cell forming branching network called mycelium
hyphae
asexual spores formed by segmentation of hyphae
arthroconidia
dermatophyte growth pattern with spore forming a sheath on the surface of hair shaft
ectothrix
dermatophyte growth pattern of spores forming within the hair shaft
endothrix
dermatophyte growth pattern with hyphae and air spaces within the hair shaft
favus
melanin in the cell wall of hyphae and spores forming darkly pigmented fungus
dematiaceous
dermatophytes usually from guinea pigs and rabbits
Trichophyton interdigitale
dermatophytes usually from cats and dogs
Microsporum canis
most common geophilic dermatophyte cultured in humans
Microsporum gypseum
component of fungal cell wall that inhibits keratinocyte proliferation and cell mediated immunity
mannan
what fluoresces under woods lamp in tinea capitis ectothrix
pteridine
noninflammatory tinea capitis is also called?
seborrheic type
always inflammatory
trichophyton schonleinii
trichophyton verrucosum
microsporum gypsum
microsporum nanum
thick yellow crusts ob hair follicles
scutula
most common cause of tinea corporis gladiatorum
trichophyton tonsurans
most common cause of tinea corporis
trichophyton rubrum
most common cause of tinea incognito
trichophyton rubrum
differentiate tinea incognito from imbricata
incognito - concentric rings of vesicles
imbricata is rarely vesicular
