Abstract

An integrated systematic study was carried out to clarify the taxonomical position and relationship of Fusarium langsethiae to other taxa within the Fusarium section Sporotrichiella. Strains of this species were compared with strains of the closely related species Fusarium poae and Fusarium sporotrichioides using a composite dataset. This set consisted of DNA sequences derived from the ribosomal internal transcribed spacer (ITS) regions, partial sequences of the ribosomal intergenic spacer (IGS) region, the beta-tubulin and translation elongation factor-1 alpha (EF-1alpha) genes, AFLP fingerprints, chromatographic data on secondary metabolites and morphological data and growth characteristics. From these combined data, a consensus matrix was calculated by taking the mean of all pairwise distances between single isolates over all separate datasets. The consensus matrix was used as the basis for the construction of a UPGMA dendrogram and a multidimensional scaling, both of which revealed a clear separation of the three taxa. Partial IGS, EF-1alpha and beta-tubulin sequence-as well as chromatography-and AFLP-derived similarities turned out to be comparably consistent, while ITS sequence- and morphology-derived similarity matrices ...Continue Reading

Autoimmune Polyendocrine Syndromes

This feed focuses on a rare genetic condition called Autoimmune Polyendocrine Syndromes, which are characterized by autoantibodies against multiple endocrine organs. This can lead to Type I Diabetes.

Autoimmune Polyendocrinopathies

Autoimmune polyendocrinopathies, also called polyglandular autoimmune syndromes (PGASs), or polyendocrine autoimmune syndromes(PASs), are a heterogeneous group of rare diseases characterized by autoimmune activity against more than one endocrine organ, although non-endocrine organs can be affected.
