The systematic position of 16 yeast strains isolated from Thailand, Hungary, The Netherlands, and the Republic of Poland were evaluated using morphological, physiological, and phylogenetic analyses. Based on the similarity of the D1/D2 domain of the LSU rRNA gene, the strains were assigned to two distinct species, Trichosporiella flavificans and representatives of a new yeast species. Phylogenetic analyses revealed that Candida ghanaensis CBS 8798T showed a strong relationship with the aforementioned two species. The more fascinating issue is that Candida and Trichosporiella genera have been placed in different subphyla, Saccharomycotina and Pezizomycotina, respectively. The close relationship between Trichosporiella flavificans, Candida ghanaensis and the undescribed species was unexpected and needed to be clarified. As for morphological and physiological characteristics, the three yeast species shared a hairy colony appearance and an ability to assimilate 18 carbon sources. Based on phylogenetic analyses carried out in the present study, Crinitomyces gen. nov. was proposed to accommodate the new yeast species, Crinitomyces reliqui sp. nov. (Holotype: TBRC 15054, Isotypes: DMKU-FW23-23 and PYCC 9001). In addition, the two species Trichosporiella flavificans and Candida ghanaensis were reassigned to the genus Crinitomyces as, Crinitomyces flavificans (Type: CBS 760.79) comb. nov. and Crinitomyces ghanaensis (Type: CBS 8798) comb. nov., respectively.

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.
