What is the morphology of Coccidioides immitis?
C immitis is a dimorphic fungus that exhibits morphological variation in its mycelial and parasitic forms. It exists in the desert soil as a mold. As the cells degenerate, barrel-shaped arthroconidia break off from the hyphae and become airborne.
What is the structure of coccidioidomycosis?
Coccidioides immitis is a unique fungal pathogen, characterized by a saprobic mycelial phase that gives rise to infectious arthroconidia which in host tissue, convert into a morphologically distinct spherule-endospore phase.
What type of microbe is Coccidioides immitis?
Coccidioides immitis is a pathogenic fungus that resides in the soil in certain parts of the southwestern United States, northern Mexico, and a few other areas in the Western Hemisphere.
Is Coccidioides immitis gram positive?
The Gram stain does not normally stain Coccidioides spp. and should not be used as a primary screening method. The presence of endospore-containing spherules is diagnostic of coccidioidomycosis.
What does Coccidioides immitis do?
Coccidioides immitis is found in the semi-arid desert climate of the southwestern United States. The organisms are inhaled as spores, causing an acute disease characterized by fever, chills, chest pain, dyspnea, and hemoptysis.

What does Coccidioides immitis cause?
Valley fever is a fungal disease that occurs only in certain parts of the United States and South America. A person can only contract it by inhaling fungal spores. It can lead to fever, chest pain, coughing, and some other symptoms. Valley fever is caused by the fungus Coccidioides immitis (C.
Is Coccidioides immitis dimorphic?
Coccidioides immitis and C. posadasii are two highly pathogenic dimorphic fungal species that are endemic in the arid areas of the new world, including the region from west Texas to southern and central California in the USA that cause coccidioidomycosis (also known as Valley Fever).
What are the characteristics of Coccidioides immitis?
What disease does Coccidioides immitis cause?
Valley fever is caused by a person inhaling spores of certain fungi. The fungi that cause valley fever — Coccidioides immitis or Coccidioides posadasii — live in the soil in parts of Arizona, Nevada, Utah, New Mexico, California, Texas and Washington. It’s named after the San Joaquin Valley in California.
