Article Abstract

Wood-inhabiting fungi play a fundamental role in ecosystem processes, particularly in wood degradation and the recycling of organic matter. In this study, a new genus, , and five new species, viz. , , , , and , are described from China and illustrated based on morphological characteristics and molecular phylogenetic analyses. Sequences of the ITS+nLSU genes were used for the phylogenetic analyses using Maximum Likelihood, Maximum Parsimony, and Bayesian Inference methods. The phylogram of the family Hydnaceae, based on the ITS+nLSU rDNA gene regions, included four genera; , , and The topology based on these sequences revealed that was closely related to , and was grouped with . The taxon was sister to the clade that included and . The species was grouped closely with and . All new taxa can be readily recognized by their macroscopic and anatomical characteristics. The five new species, closely related taxa in the phylogenetic tree, and morphologically similar species are discussed.

Hepatitis E virus (HEV) has emerged as a major agent of acute viral hepatitis, with zoonotic genotype 4 (HEV-4) representing a public health concern in China. In this study, we integrated province-wide enhanced hepatitis E surveillance data and molecular profiling from Shandong Province of eastern China, 2019-2023, with the aim of elucidating the epidemiology, genetic diversity, and clinical correlations of autochthonous HEV infections. In total, 5826 cases were reported during the study period, with 72.

Recent advances in methods to infer and analyse ancestral recombination graphs (ARGs) are providing powerful new insights in evolutionary biology and beyond. Existing inference approaches tend to be designed for use with fully-phased datasets, and some rely on model assumptions about demography and recombination rate. Here I describe a simple model-free approach for genealogical inference along the genome from unphased genotype data called Sequential Tree Inference by Collecting Compatible Sites (sticcs).

Many adenovirus (AdV) species have been isolated from human and non-human primates. Here we describe the isolation of a new AdV from a western lowland gorilla held captive in a zoo. Analysis of the genome sequence demonstrated that this virus is a member of the Mastadenovirus genus, but markedly distinct from all previously described species.

Introduction: Pigeon paramyxovirus type 1 (PPMV-1) is an antigenic variant of Avian Orthoavulavirus 1 (AOAV-1) (Newcastle disease virus) with a global distribution that causes lethal infections in pigeon and dove species. AOAV-1's infecting humans normally cause mild, self-limiting conjunctivitis, but since 2003, PPMV-1 has been associated with an increased number of severe and lethal respiratory and neurological infections in immunocompromised persons in the Netherlands, the USA, France, China and Australia.

Methods: PPMV-1's isolated from free-living pigeons and doves across South Africa from 2012 to 2024 were sequenced using conventional or next generation technologies.
