Definition
found in domestic animals and rodents, but not transmitted person-person or animal-person
Term
Coccidioides immitis
Definition
Tissue rxn suppurative with neutrophils containing endospores with doubly refractile walls. becomes necrotic followed by granulomas producing cavities and nodules. results in scarring.
