Mycology and Virology: Medical Fungi Flashcards
a genus of molds commonly found in the environment. It can cause a range of infections, including allergic reactions, aspergillosis (lung infections), and invasive aspergillosis, which can be life-threatening in individuals with weakened immune systems.
Aspergillus spp
causes oral thrush and vaginal yeast infection
Candida spp.
this fungi is found particularly in individuals with poorly controlled diabetes or compromised immune systems
Mucorales
Risk factors for this species include weakened immune system (especially in people with conditions like leukemia, organ transplantation, or HIV), lung diseases, and certain medications.
Aspergillus
stained used in staining inner capsule of C. neoformans red.
Mucicarmine stain
a group of fungi that primarily infect the skin, hair, and nails.
Dermatophytes
most common form of cryptococcal infections
Pulmonary Cryptococcosis
In its mold form, Histoplasma capsulatum produces small round spores called ______.
conidia
a common dermatophyte infection that is a fungal infection of the feet, particularly between the toes. It can cause itching, redness, and peeling of the skin.
Tinea Pedis (Athlete’s Foot)
causes Tinea barbae and Tine corporis
Tricophyton mentagrophytes
Tinea versicolor is caused by
Malassezia furfur
Tinea cruris is also known as
Jock’s itch
can present as a mild respiratory illness or as a severe disseminated infection affecting multiple organs
Histoplasma capsulatum
other word for Tinea unguium
onychomycosis
fluoresces under Wood’s lamp examination.
Microsporum canis
**
This fungus is found in moist soil and decaying organic matter in certain regions of North America. Inhalation of spores can lead to a respiratory infectionknown as blastomycosis.
Blastomyces dermatitidis
is a dimorphic fungus found in soil, particularly in regions with high bird or bat droppings
Histoplasma capsularum
shows narrow budding yeast
Grocott’s methenamine silver stain
erythematous lesions in the groin
Tinea cruris
athlete’s foot is also known as
Tinea pedis
what are the samples observed in microscopic evaluation for fungal infections?
hyphae (filaments) or spores
This is an antifungal medication that inhibits synthesis of ergosterol, a key component of fungal cell membranes.
Azoles
Antifungal medications that disrupts fungal cell wall synthesis that inhibits the enzyme beta-glucan synthase.
Echinocandins
Examples of these medications are caspofungin, micafungin, and anidulafungin.
