What is Coccidioidal meningitis?

One of the most severe is coccidioidal meningitis, a form of disseminated infection. As with other forms of extrathoracic disseminated coccidioidal infection, Coccidioides appear to spread hematogenously after an initial pulmonary infection and establish a tissue-destructive lesion in the meninges.

How is coccidioidomycosis transmitted?

Coccidioidomycosis is typically transmitted by inhalation of airborne spores of C immitis or C posadasii (see Etiology). Infection occurs in endemic areas and is most commonly acquired in the summer or the late fall during outdoor activities.

How is coccidioidomycosis diagnosed?

Other tests that may help diagnose coccidioidomycosis are: Sputum samples, produced by coughing or obtained by bronchoscopy, to look for the fungus in a lab culture. Chest X-ray and/or CT scan (to look for pneumonia) Biopsy of the affected site, typically the lung, to look for the fungus in the infected tissue.

Where is coccidioidomycosis found?

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.

  4. Use air filters indoors.

How do I know if I have Coccidioides immitis?

Conventional laboratory identification methods used to identify Coccidioides immitis include culture on fungal media, growth rate, colony morphology, microscopic morphology, animal inoculation, and biochemical tests. Identification begins with culture of the clinical specimen on fungal media.

Is Coccidioides a yeast or mold?

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.

Is Aspergillus black mold?

The fungus Aspergillus niger is a type of mould, which can sometimes be attributed to the cause of some cases of pneumonia. It is also the causative agent of ‘black mould’ on the outsides of certain foods, such as apricots, onions, grapes, etc – therefore making Aspergillus niger a food ‘spoilage’ organism.
