| genetic diversity among clinical coccidioides spp. isolates in arizona. | increasing coccidioidomycosis rates in arizona may indicate the development of a hypervirulent strain. one hundred and twenty-one clinical coccidioides spp. isolates were collected over 16 months from maricopa, graham, yuma, and pima counties in arizona. the patient age distribution ranged from 9 to 91 years, with a median age of 58 years; 36% were female, and 64% male. all isolates were analyzed by measuring length polymorphisms in nine distinct microsatellite regions. the three microsatellites ... | 2008 | 18608919 |
| increase in coccidioidomycosis - california, 2000-2007. | coccidioidomycosis is an infection resulting from inhalation of airborne spores of coccidioides immitis or coccidioides posadasii, soil-dwelling fungi endemic to california's san joaquin valley; southern regions of arizona, utah, nevada, and new mexico; western texas; and regions of mexico and central and south america. of an estimated 150,000 new infections annually in the united states, approximately 60% are asymptomatic. patients with symptoms usually experience a self-limited influenza-like ... | 2009 | 19214158 |
| use of population genetics to assess the ecology, evolution, and population structure of coccidioides. | during the past 20 years, a general picture of the genetic diversity and population structure of coccidioides, the causal agent of coccidioidomycosis (valley fever), has emerged. the genus consists of 2 genetically diverse species, c. immitis and c. posadasii, each of which contains 1 or more distinct populations with limited gene flow. genotypic data indicate that c. immitis is divided into 2 subpopulations (central and southern california populations) and c. posadasii is divided into 3 subpopu ... | 2016 | 27191589 |
| local population structure and patterns of western hemisphere dispersal for coccidioides spp., the fungal cause of valley fever. | coccidioidomycosis (or valley fever) is a fungal disease with high morbidity and mortality that affects tens of thousands of people each year. this infection is caused by two sibling species, coccidioides immitis and c. posadasii, which are endemic to specific arid locales throughout the western hemisphere, particularly the desert southwest of the united states. recent epidemiological and population genetic data suggest that the geographic range of coccidioidomycosis is expanding, as new endemic ... | 2016 | 27118594 |
| [a case of coccidioidomycosis in turkey imported from the united states of america]. | coccidioidomycosis caused by coccidioides immitis or coccidioides posadasii is a rare infectious disease except in endemic regions. in this report the third documented imported case of coccidioidomycosis in turkey was presented. a thirty-year-old male patient was admitted to our hospital with fever and purulent drainage from his chest tube. he had worked in arizona, usa, until 4 months before this presentation. while in arizona, he experienced cough and hemoptysis and was diagnosed as pulmonary ... | 2017 | 28566083 |
