common skin condition caused by surface infection with type of yeast that normally lives on skin | Tinea versicolor |
what prep dissolves epithelial cells to reveal hyphae with characteristic branching patterns | KOH preps |
cutaneous funcus that infect skin, hair, nails, grow in keratinized layer of skin, not invasive into underlying tissue, leads to scaling of skin via keratinase | Dermatophytes, contagious |
Tineas, dermatophytes characterized by ___ | location |
Tinea capitis | hair/scalp |
beared area tinea____ | barbae |
'athlete's foot" | tinea pedis |
tinea cruris | groin/perineal, "jock itch" |

Tinea corporis | fungal infection of body/face |
mold found on rose thorns, hay, sphagnum moss, twigs, soil | Sporotrichosis, "rose Gardener's disease" |
diaper rash, yeast vaginitis, thrush caused by | Candida |
hosts for candida | immunocopromised |
yeast with a capsule | cryptococcus neoformans |
systemic disease, of reticuloendothelial system, manifest in bones marro, lungs, liver, spleen from blackbird roosts, chicken house, bat guano | Histoplasma capsulatum |
endemic in Ohis, Missouri, Mississippi River valeys, thrives on rich, damp soil | Histoplasma capsulatum |
etiologic for coccidioidomycosis in San Joaquin Valley of Fever | Coccidioides immitis |
primarily a pulmonary dz, the spherules enlarge and divide, rupture, releasing endospores and reproduce | coccidioidomycosis |
chronic granulomatoud dz progresses slowly, pulm/skin infection common, but also bone, prostate | Blastomyces dermatitidis |
meningitis, pulmonary; ecological niche is pigeon, chicken droppings and spread through respiratory system; yeast spherical cells, buds are narrow based, surrounded by capsule | cryptococcus neoformans |
hyphae, small airborne conida, ubiquitous, from moldy organic material, inhaled, seen by silver stain | aspergillus fumigatus |
non-septate filamentous hyphae, proliferate in blood vessel walls, infections in ketoacidotic diabetics and cancer pts | Mucor and Rhizopus |
obligate organisms, not grown in lab, common, causes atypical PNA if immunocompromised or premies causes interstitial PNA | Pneumocystis jiroveci |
student in town in Ohio river valley became ill after leaning chicken coup, whith organism is most likely responsible? | Histoplasma capsulatum |
branching G(+) rod part of the oral cavity flora, can invade across fascial planes to produce draining sinuses | Actinomyces isrealii |
monomorphic fungus opportunistic especially in neuropenics | Aspergillus fumigatus |
normal flora in humans, can be opportunistic if there is a defect in cell mediated immunity | Candida albicans |
primary fungal pathogen causing meningitis | Cryptococcus neoformans |
primary fungal pathogen causing PNA if inhaled | Coccidioides immitis |
