Chapter 22, Problem 6
Indicate whether each statement is true or false. If the statement is false, change the underlined word or phrase to make the statement true.
_____ Coccidioidomycosis does not occur normally outside the Western Hemisphere.
Verified step by step guidance1
Step 1: Understand the statement: 'Coccidioidomycosis does not occur normally outside the Western Hemisphere.' This is a geographical and epidemiological claim about the distribution of the disease.
Step 2: Recall that Coccidioidomycosis, also known as Valley fever, is caused by fungi of the genus Coccidioides, which are endemic primarily in certain arid regions of the Western Hemisphere, especially the southwestern United States, parts of Mexico, and Central and South America.
Step 3: Evaluate the truth of the statement based on the known endemic regions. Since Coccidioidomycosis is typically found in the Western Hemisphere and is rare or absent in other parts of the world, the statement is true as it stands.
Step 4: If the statement were false, you would need to identify a region outside the Western Hemisphere where Coccidioidomycosis occurs normally and replace 'Western Hemisphere' with that region. However, no such region is known for endemic Coccidioidomycosis.
Step 5: Conclude that the statement is true and no changes are necessary.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Geographical Distribution of Coccidioidomycosis
Coccidioidomycosis, also known as Valley fever, is primarily found in arid regions of the Western Hemisphere, especially the southwestern United States, parts of Mexico, and Central and South America. Understanding its endemic areas is crucial for diagnosing and managing the disease.

Types of Flagellar Distribution on Bacteria
Etiology and Pathogen Characteristics
Coccidioidomycosis is caused by the fungi Coccidioides immitis and Coccidioides posadasii. These fungi thrive in soil and release spores that can be inhaled, leading to infection. Recognizing the pathogen helps in understanding disease transmission and epidemiology.
