Coccidioides causes a condition known as valley flower. Hyphae of this fungus separate into thick-walled arthrospores at maturity. Under the favorable condition, arthrospore germinates into parasitic phase. This parasitic phase swells and forms giant sporangium to form spores which appears similar to endospores.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
