| multi-resistant aspergillosis due to cryptic species. | reports of cryptic species causing aspergillosis in humans are increasing in the literature. cryptic species are defined as those which are morphologically indistinguishable, although their identifications can be confirmed using molecular or other techniques which continue to become more widely available in the clinical setting. antifungal resistance has often been noted in these cases, and indeed there does appear to be a higher prevalence of reduced susceptibility in cryptic species. many of t ... | 2014 | 24969615 |
| aspergillus fumigatus-related species in clinical practice. | aspergillus fumigatus is the main etiologic agent of invasive aspergillosis (ia). other aspergillus species belonging to the section fumigati (a. fumigatus complex) may occasionally be the cause of ia. these strains are often misidentified, as they cannot be distinguished from a. fumigatus by conventional morphological analysis and sequencing methods. this lack of recognition may have important consequences as these a. fumigatus-related species often display some level of intrinsic resistance to ... | 2016 | 27242710 |
| diversity and specificity of microsatellites within aspergillus section fumigati. | microsatellites (or short tandem repeats, strs) are the genetic markers of choice for studying aspergillus fumigatus molecular epidemiology due to its reproducibility and high discrimination power. however, the specificity of these markers must be investigated in a group of isolates from closely related species. the aim of this work was to test a microsatellite-based pcr multiplex previously designed for a. fumigatus in a set of species belonging to section fumigati, namely aspergillus fumigatia ... | 2012 | 22838495 |
