What type of environment is Coccidiodes commonly found in?

1. Coastal regions

2. Wetland areas

3. Southwestern U.S. soil

4. Urban landscapes

The correct answer is: Southwestern U.S. soil

Coccidioides is a fungus that is primarily found in the soil of certain regions, particularly in the Southwestern United States. This organism thrives in arid and semiarid environments, where the soil conditions are favorable for its growth. The spores can become airborne when the soil is disturbed, which is a significant concern for those working in or around these areas due to the health implications of inhaling these spores. The type of environment where Coccidioides is commonly found, namely the Southwestern U.S. soil, is characterized by dry, dusty conditions that are conducive to the lifecycle of the fungus. Regions such as Arizona and California are particularly known for having Coccidioides present in the soil. In contrast, coastal regions, wetland areas, and urban landscapes do not provide the same conditions that promote the growth of Coccidioides. These environments either have higher moisture levels or human development that may disrupt the natural habitat necessary for the fungus to thrive. Therefore, the correct answer is rooted in the unique climatic and soil conditions of the Southwestern U.S., which allows Coccidioides to flourish.
