BACKGROUND Apophysomyces is a monotypic genus belonging to the order Mucorales. The species Apophysomyces elegans has been reported to cause severe infections in immunocompromised and immunocompetent people. In a previous study of Alvarez et al.(3) [J Clin Microbiol 2009;47:1650-6], we demonstrated a high variability among the 5.8S rRNA gene sequences of… (More)
We report the presence of the two arthroconidial anamorphic fungi, Scytalidium cuboideum and Arthropsis hispanica, in clinical samples from the USA. Both fungi were morphologically and molecularly identified. The antifungal susceptibility of four isolates of A. hispanica and five of S. cuboideum to eight antifungal drugs is provided.
Sporothrix globosa, reported from the USA, Europe, and Asia, is a recently described pathogenic species morphologically similar to Sporothrix schenckii. In this study, the phylogenetic affinities of 32 clinical and environmental isolates morphologically identified as S. schenckii, from Mexico, Guatemala, and Colombia, were assessed by cladistic analysis of… (More)
The new variety of Actinomucor elegans var. kuwaitiensis, isolated from an open necrotic wound of a diabetic patient is described. This strain differed from the two previously described varieties of A. elegans, A. elegans var. elegans and A. elegans var. meitauzae by nearly 1% or more sequence divergence within D1/D2 regions of 28S rRNA and the ITS region… (More)
In this paper, we give a necessary and sufficient condition for an algebraic ODE to have an algebraic general solution. For a first order autonomous ODE, we give an optimal bound for the degree of its algebraic general solutions and a polynomial-time algorithm to compute an algebraic general solution if it exists. Here an algebraic ODE means that an ODE… (More)
The fungal genus Curvularia includes numerous plant pathogens and some emerging opportunistic pathogens of humans. In a previous study we used morphology and sequences of the nuclear ribosomal internal transcribed spacer region (ITS) and the glyceraldehyde-3-phosphate dehydrogenase (gpd) gene to identify species within a set of 99 clinical Curvularia… (More)
This paper describes an algorithmic method iterative method for searching power series solutions of a partial differential equation. Power series expansions considered have support in some convex cone of <b>R</b><sup>N</sup>. We do this by introducing a <i>N</i>-variables analog of the Newton polygon construction, used in the case of ordinary differential… (More)
The circumscription of the genus Acremonium (Hypocreales) was recently reviewed on the basis of a DNA phylogenetic study. Several species were subsequently transferred to Sarocladium, but the relationships between both genera remained unresolved. Based on multilocus phylogenetic inferences combined with phenotypic data, we have revised the species concepts… (More)
