As molecular-based investigations begin to uncover the large degree of genetic variation that can exist within dermatophyte species, and population-based studies reveal exceedingly high rates of endemicity for these organisms, species typing has become inadequate to gain insight into these pathogens and the nature of the infections that they cause. This review examines studies that have applied strain typing strategies to explore intra-specific genetic diversity among the dermatophytes in attempts to address a number of relevant clinico-epidemiologic questions about these common fungal pathogens.

Cephalosporin C (CPC) is a critical raw material for cephalosporin antibiotics produced by Acremonium chrysogenum. During fermentation, the oxygen supply is a crucial factor limiting the efficient biosynthesis of CPC. This study demonstrated that the addition of exogenous surfactants significantly increased the dissolved oxygen (DO) level, extracellular catalase content, and final CPC titer.

Objective: To comprehensively explore the prognostic significance of transthoracic echocardiography (TTE) and three-dimensional speckle-tracking echocardiography (3D STE) parameters in AIS and their role in distinguishing cardioembolic stroke.
Methods: 301 acute ischemic stroke (AIS) patients were enrolled. TTE and 3D STE were employed to evaluate cardiac function and structure, also left atrial strain.

We investigate the impact of differential vaccine effectiveness, waning immunity, and natural cross-immunity on the capacity for vaccine-induced strain replacement in two-strain models of infectious disease spread. We focus specifically on the case where the first strain is more transmissible but the second strain is more immune-resistant. We consider two cases on vaccine-induced immunity: (1) a monovalent model where the second strain has immune escape with respect to vaccination; and (2) a bivalent model where the vaccine remains equally effective against both strains.

Background: In tauopathies, the protein tau misfolds into a b-sheet conformation that self-templates and spreads throughout the brain causing progressive degeneration. Biological and structural data have shown that the shape, or strain, that tau adopts when it misfolds determines which disease a patient will develop. We previously used HEK293T cells expressing TauRD-YFP to show that tau strain formation is isoform-specific.

A novel yeast species, isolated from the bark of pine trees in Gyeongju, South Korea, and designated as KCTC 37304 (ex-type KACC 410729), is characterized by its genetic, morphological and physiological properties. Molecular phylogenetic analysis involving the D1/D2 domain of the 26S LSU rRNA gene and the internal transcribed spacer (ITS) region confirms that it belongs to the genus . In comparison to CBS:10065, the type strain of its closest relative, KCTC 37304 exhibits 8 nucleotide substitutions (~2.
