How long does it take for fungal meningitis symptoms to appear?

The incubation interval—the interval between the exposure, the inoculation and the onset of symptoms—can be quite prolonged. We initially thought it might extend as long as a month. But just recently it has been suggested that it can go beyond that—two months, maybe even three months.

How do spherules form?

Answer: Spherules are the form that the fungus takes in tissue. In nature, the fungus grows in soil and appears in the mycelial form similar to bread mold. Portions of the hair-like mycelia break off into arthroconidia (“spores”) and become airborne when the soil is disturbed.

Which is the commonest cause of fungal meningitis in immunocompromised patients?

The encapsulated yeast C. neoformans is the most common cause of fungal meningitis. The first report of cryptococcal infection in humans was provided by Busse and Buschke in 1894 in a patient with bone infection and probable disseminated disease.

Is cocci mold?

Valley fever, also called coccidioidomycosis, is an infection caused by the fungus Coccidioides. The fungus is known to live in the soil in the southwestern United States and parts of Mexico and Central and South America. The fungus was also recently found in south-central Washington.

What is the treatment for fungal meningitis?

Fungal meningitis is treated with long courses of high dose antifungal medications, usually given through an IV line in the hospital. The length of treatment depends on the status of the immune system and the type of fungus that caused the infection.

Is coccidioides a mold or yeast?

Coccidioides is a dimorphic fungus, meaning that it assumes 2 different forms, yeast or mold, depending on the environment. In soil, Coccidioides grows as a mold (mycelium) with branching septate hyphae. During the rainy season, the mycelia grow rapidly, but they are also the least infectious form of the organism.
