Molecular and phenotypic characterization of anamorphic fungi

Anamorphic fungi (those reproducing asexually) are a big part of kingdom Fungi. Most of them occur as saprobes in nature, but numerous species are pathogenic to plants and animals including man. With the aim of contributing to the knowledge of the diversity and distribution of anamorphic fungi, we p...

Most of them occur as saprobes in nature, but numerous species are pathogenic to plants and animals including man. With the aim of contributing to the knowledge of the diversity and distribution of anamorphic fungi, we performed a phenotypic and molecular characterization of environmental and clinical isolates of these fungi. Based on a polyphasic taxonomy approach which included morphology, physiology and DNA sequence analyses we described the following new taxa: Cladorrhinum flexuosum, C. microsclerotigenum, Fibulochlamys chilensis, Ramophialophora humicola, Sporothrix brunneoviolacea, S. dimorphospora and Leptodiscella brevicatenata, most of which were isolated from soil. A phylogenetic study of clinical isolates of the genus Sporothrix revealed the presence of the recently described pathogen S. globosa in Mexico, Central (Guatemala) and South America (Colombia) for the first time.Los hongos anamórficos son un vasto grupo dentro del reino Fungi, caracterizado por reproducirse asexualmente. Aunque la mayoría de ellos son saprófitos, un gran número de especies atacan plantas y animales, incluido el ser humano. Con el fin de contribuir al conocimiento de la diversidad y distribución geográfica de los hongos anamórficos, en la presente tesis se realizó una caracterización fenotípica y molecular de aislamientos ambientales y clínicos de estos hongos. Mediante un estudio de taxonomía polifásica que incluyó morfología, fisiología y análisis de secuencias de ADN, se propusieron los siguientes nuevos taxones: Cladorrhinum flexuosum, C. microsclerotigenum, Fibulochlamys chilensis, Ramophialophora humicola, Sporothrix brunneoviolacea, S. dimorphospora y Leptodiscella brevicatenata, todos ellos aislados desde muestras ambientales, principalmente de suelo. Un estudio filogenético de cepas clínicas del género Sporothrix reveló por primera vez la presencia de S. globosa, una especie recientemente descrita, en México, América Central (Guatemala) y América del Sur (Colombia).Universitat Rovira i Virgili Departament de Filologia CatalanaUniversitat Rovira i Virgili.2011info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdf210 p.https://hdl.handle.net/20.500.11797/TDX950http://hdl.handle.net/10803/37344reponame:Repositori Institucional de la Universitat Rovira i Virgiliinstname:Universitat Rovira i virgili (URV)Inglésinfo:eu-repo/semantics/openAccessADVERTIMENT.
