Septate and Hyaline Saprophytes Flashcards
ubiquitous environmental saprophytes and can frequently be isolated from a number of hospital sites, including ventilation systems, and food
Aspergillus
second most commonly isolated fungus after Candida
aspergilllus
most commonly seen in Aspergillus
A. fumigatus
pathogenuc species in Aspergillus
A. fumigatus
A. flavus
A. terreus
A. niger
Their conidia are constantly inhaled, but they are generally readily cleared in healthy, immunocompetent individuals.
Aspergillus
Mortality from this infections caused remains high, especially in the immunocompromised host.
aspergillus
the most frequent cause of disease in bone marrow transplant recipients, in addition to other transplant recipients and those with cancer.
aspergillus
The infection easily spreads hematogenously, and it is not uncommon to find multiorgan system involvement, including the brain, liver, heart, and bone.
It also triggers allergic reactions and are a common cause of sensitivities to molds.
aspergillus
Most known pathogens in this group form green- to tan-colored colonies.
aspergillus
Disease caused by Aspergillus:
- Allergic Bronchopulmonary Aspergillosis
- Allergic Aspergillosis Sinusitis
- Aspergilloma
- Chronic pulmonary Aspergillosis
- Cutaneous Skin Aspergillosis
- Invasive Aspergillosis
Risk factors of Aspergillus:
- Weak immune system
- Organ transplant
- Asthma
- Chronic Obstructive lung disease
- Chemotherapy for malignancy
Colors range from black to white and include yellow, brown, green, gray, pink, beige, and tan.
Aspergillus
rare human isolate, uncommonly associated with keratitis.
beauveria
a known insect pathogen and is found worldwide on vegetation and in soil.
beauveria
Abundant, single-celled, tear-shaped sympoduloconidia are formed on sympodulae, which taper extremely from a rather swollen base
beauveria
Colonies are hyaline, moderately rapidly growing, fluffy colonies, sometimes developing a powdery surface reminiscent of T. mentagrophytes
beauveria
Colonies are hyaline with a moderate growth rate and with age can develop light shades of pink, gray, or tan pigment.
chrysosporium
A rare cause of disease, recovered from nails and skin lesions.
chrysosporium
_________ has been linked to pneumonia and osteomyelitis in immunocompromised patients.
Chrysosporium zonatum
are frequently seen in mycotic keratitis.
fusarium
are easily recovered in blood culture systems.
fusarium
rapidly growing hyaline fungus that can develop various colors with age, ranging from rose to mauve to purple to yellow.
fusarium
has been implicated in pulmonary disease in immunocompromised patients.
Geotrichum
Colonies appear white to cream and yeastlike and can be confused with Trichosporon spp.
geotrichum
previously Paecilomyces lilacinus, has been associated with cutaneous and subcutaneous infections, in addition to pyelonephritis, endocarditis, and pulmonary infections in immunocompromised and immunocompetent patients.
purpureocillium
It was recovered in a hospital outbreak with a high rate of associated death.
purpureocillium
are potentially serious and difficult to treat; care should be taken when encountering fungi that are mauve in color
purpureocillium
are inhibited at 37°C, they rarely cause infections.
penicillium
Most reports of disease involve chronic fungal sinusitis
penicillium
Ubiquitous in nature, these fungi can be recovered from any location worldwide.
penicillium
commonly isolated from nail specimens and have been implicated in pulmonary disease in immunocompromised patients.
Scopulariopsis
emerging as pathogens that can cause a range of infections, including pulmonary and skin infections, in the immunocompromised host.
trichoderma
