Abstract During infection, the host utilizes multiple mechanisms to prevent colonization and dissemination. Protection begins at surface, often via commensal community found within our respiratory, skin, intestinal tract. Microbiota disruption reduces effectiveness of this protective barrier. Coccidioidomycosis, or Valley fever, is misdiagnosed as acquired bacterial pneumonia treated with antib...
Forty-nine isolates of arthroconidial fungi other than Coccidioides immitis did not produce immunodiffusion lines of identity with the reference system for that fungus.
BACKGROUND Coccidioidomycosis, a potentially fatal fungal infection, is considered an emergent mycotic disease because of the increased incidence of fungal infections registered over recent years. Infection occurs through the inhalation of arthroconidia from two main species of Coccidioides: Coccidioides immitis and C. posadasii, which are both endemic to arid and semi-arid regions of North Ame...
While most Ascomycetes tend to associate principally with plants, the dimorphic fungi Coccidioides immitis and Coccidioides posadasii are primary pathogens of immunocompetent mammals, including humans. Infection results from environmental exposure to Coccidiodies, which is believed to grow as a soil saprophyte in arid deserts. To investigate hypotheses about the life history and evolution of Co...
Coccidioides posadasii sp. nov., formerly known as non-California (non-CA) Coccidioides immitis, is described. Phylogenetic analyses using single nucleotide polymorphisms, genes, and microsatellites show that C. posadasii represents a divergent, genetically recombining monophyletic clade. Coccidioides posadasii can be distinguished from C. immitis by numerous DNA polymorphisms, and we show how ...
Coccidioides is a primary fungal pathogen of humans, causing life-threatening respiratory disease known as coccidioidomycosis (Valley fever) in immunocompromised individuals. Recently, Sharpton et al (2009) found that the deuterolysin (M35) family genes were significantly expanded in both the Coccidioides genus and in U. reesii, and that Coccidioides has acquired three more M35 family genes tha...
Coccidioidomycosis is a fungal infection caused by Coccidioides posadasii and Coccidioides immitis. It is estimated that 150,000 new infections occur in the United States each year. The incidence of this infection continues to rise in endemic regions. There is an urgent need for the development of better therapeutic drugs and a vaccine against coccidioidomycosis. This review discusses the featu...
The Research Center for Pathogenic Fungi and Microbial Toxicoses, Chiba University is the only organization in Japan to possess a series isolates of Coccidioides spp., which are the most virulent pathogenic fungi and which are treated as biosafety level 3 microorganisms. Recently, the genus Coccidioides has been classified into two species, C. immitis and C. posadasii, based on their endemic ar...
Background: The role of advanced diagnostic bronchoscopy (ADB) for assessing atypical respiratory infections is unclear. purpose this study was to ascertain: (I) the utility ADB-tissue sampling in patients with focal thoracic lesions due infections; (II) how multimodal bronchoscopic and testing enhance diagnosis a Coccidioides-endemic region.
INTRODUCTION Community-acquired pneumonia is the most common manifestation in primary coccidioides infections (Coccidioides immitis, C. posadasii). It is essential that this endemic dimorphic fungus be considered in order to proceed with the most appropriate diagnostic tools and therapy. CASE PRESENTATION We present a rare case of primary pleural coccidioides and a review of the current liter...
