Coccidioides immitis is a soil saprophyte found mainly in desert areas of the south-western USA.
It can cause a kennel-cough-like syndrome in dogs. Feline infection is very rare: in cat generally see skin lesions, possibly with respiratory signs.
Diagnosis is by serology and culture. Treatment of choice is long-term ketoconazole (5-10 mg/kg orally twice
for up to a year, then maintenance at 2-5 mg/kg daily to prevent relapses).
