Taxonomic and diagnostic markers for identification of Coccidioides immitis and Coccidioides posadasii.
The ribosomal Internal Transcribed Spacer (ITS) regions of the two recognized species of Coccidioides were studied using a reference set of strains that had been previously identified with species defining microsatellite polymorphisms. Unambiguous identification of the two species proved to be possible by amplifying and sequencing the ITS region. PCR-reactions are sensitive to amplification con...
متن کاملGenetic analysis of the endemic fungal pathogens Coccidioides posadasii and Coccidioides immitis in Mexico.
Coccidioidomycosis (CM) is a mycotic disease that affects mammals, including humans. Official data relative to CM in Mexico has not been collected since 1995, thus its prevalence remains unknown. The objectives of this study were to identify the predominant Coccidioides species in Mexico, infer their current geographical distribution and explore the correlation between species and clinical pres...
متن کاملPolysaccharide of Coccidioides immitis.
Pappagianis, D. (University of California, Berkeley), E. W. Putman, and G. S. Kobayashi. Polysaccharide of Coccidioides immitis. J. Bacteriol. 82:714-723. 1961.-Soluble polysaccharide from mycelia or culture filtrates of Coccidioides immitis was found to consist mainly of mannose, but also included small quantities of galactose and another reducing sugar. Isolation of the polysaccharide by etha...
متن کاملGenetic diversity of Coccidioides posadasii from Brazil.
Studies of the genetic variation within populations of Coccidioides posadasii are scarce, especially for those recovered from South America. Understanding the distribution of genotypes among populations is important for epidemiological surveillance. This study evaluated the genetic diversity of 18 Brazilian strains of C. posadasii through the sequencing of the 18-28S region of nuclear rDNA, as ...
متن کاملMolecular and phenotypic description of Coccidioides posadasii sp. nov., previously recognized as the non-California population of Coccidioides immitis.
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 ...
