Valley fever: finding new places for an old disease: Coccidioides immitis found in Washington State soil associated with recent human infection.
نویسندگان
چکیده
We used real-time polymerase chain reaction and culture to demonstrate persistent colonization of soils by Coccidioides immitis, an agent of valley fever, in Washington State linked to recent human infections and located outside the endemic range. Whole-genome sequencing confirmed genetic identity between isolates from soil and one of the case-patients.

Exploring the Distribution of Coccidioides immitis in South Central Washington State
Introduction Coccidioidomycosis, commonly referred to as Valley Fever, is caused by the soil-borne saprophytic fungus C. immitis and posadasii. These species have historically been found in the desert southwest and Mexico; however, in 2010 there were three coccidioidomycosis cases identified in central Washington. Colonization of soils by C. immitis has been confirmed at exposure sites associat...
متن کاملCoccidioides immitis Identified in Soil Outside of Its Known Range — Washington, 2013
Coccidioidomycosis ("valley fever") is caused by inhaling spores of the soil-dwelling fungi Coccidioides immitis or Coccidioides posadasii. Most infections are subclinical. When clinical manifestations do occur (typically 1-4 weeks after exposure), they are similar to those associated with influenza or community-acquired pneumonia. Disseminated disease is rare. Residual pulmonary nodules can le...
متن کاملClimate controls on valley fever incidence in Kern County, California.
Coccidiodomycosis (valley fever) is a systemic infection caused by inhalation of airborne spores from Coccidioides immitis, a soil-dwelling fungus found in the southwestern United States, parts of Mexico, and Central and South America. Dust storms help disperse C. immitis so risk factors for valley fever include conditions favorable for fungal growth (moist, warm soil) and for aeolian soil eros...
متن کاملEnvironmental variability and coccidioidomycosis (valley fever)
Coccidioidomycosis (valley fever) is a disease endemic to arid regions in the western hemisphere, and is caused by the soil-dwelling fungus Coccidioides immitis (C. immitis). In this paper, we provide an overview of the current state of knowledge regarding valley fever and C. immitis as related to climatic conditions and habitat requirements. Previous research shows there is a relationship betw...
متن کاملClimate and Coccidioidomycosis incidence fluctuations in Kern County, California: a review
Coccidioidomycosis (valley fever) is a fungal infection found in the southwestern US, northern Mexico, and some places in central and South America. The fungi which cause it (Coccidioides immitis and Coccidioides posadasii) are normally soil-dwelling but, if disturbed, become air-borne and infect the host when their spores are inhaled. It is thus natural to surmise that weather conditions which...
