How do you treat Aspergillus niger?

Antifungal medications. These drugs are the standard treatment for invasive pulmonary aspergillosis. The most effective treatment is a newer antifungal drug, voriconazole (Vfend). Amphotericin B is another option. All antifungal drugs can have serious side effects, including kidney and liver damage.

Which media is used for Aspergillus?

The culture of Aspergillus spp. on bacterial media is ~30% less effective than on fungal media [1]. General purpose media that are commonly used for fungal culture are Sabouraud dextrose, malt extract and less commonly brain heart infusion medium.

What disease does Aspergillus niger cause?

Aspergillus niger causes several diseases including black mold (or black rot) of onions and garlic, crown rot of peanuts, and vine canker of table grapes. In black rot of onions and garlic, A. niger develops between the outer (dead, flaky) skin and the first fleshy scales of the bulb which become water soaked.

How fast does Aspergillus grow?

present as rapidly growing molds that are visible 1-3 days after incubation. Culture allows for the microscopic identification down to the species level; however, this method is relatively insensitive, so patients with invasive aspergillosis may have negative cultures.

At what temperature does Aspergillus grow?

Unlike most fungi, Aspergillus flavus is favored by hot dry conditions. The optimum temperature for growth is 37 C (98.6 F), but the fungus readily grows between the temperatures of 25-42 C (77-108 F), and will grow at temperatures from 12-48C (54-118 F).

What are the advantages of sabouraud Agar?

SDA was designed by Sabouraud for the cultivation of fungi, especially those associated with skin infections. [6] The media is more favorable for the isolation of fungi than bacteria due to its low pH and it also helps in the identification by enhancing characteristic spores and pigment production by the fungi.

What kind of bacteria can grow in Sabouraud dextrose agar?

Sabouraud Dextrose Agar (SDA) is a selective medium primarily used for the isolation of dermatophytes. Other fungi, yeasts, and filamentous bacteria such as Nocardia can also grow in SDA. The acidic pH of this medium (pH about 5.0) inhibits the growth of bacteria but permits the growth of yeasts and most filamentous fungi.

What is the purpose of Sabouraud dextrose broth?

Sabouraud Dextrose Broth and Sabouraud Maltose Agar and Broth are also used for culturing yeasts, molds and aciduric microorganisms. Fluid Sabouraud Medium is used for cultivating yeasts, molds and aciduric microorganisms and for detecting yeasts and molds in normally sterile materials.

What kind of culture is needed for Aspergillus?

Some fungi are very slow to grow, notably Histoplasma spp., and may need longer incubation times. Culture of respiratory cultures at 42ºC prevents the growth of Candida spp. allowing Aspergillus spp. to flourish without competition. Once colonies are visible, they should be inspected carefully for their morphology.

Can you get Aspergillus ochraceopetaliformis from a nail?

Aspergillus versicolor grown on malt extract agar (left) and Sabouraud agar (middle). H&E staining of a sample of nail infected with Aspergillus ochraceopetaliformis. Aspergillus spp. isolated from nail specimens are not usually susceptible to most of the topical and systemic antifungals used to treat dermatophytes.
