| 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 unguium | nails/onychomycosis |
| 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 |
