This paper investigates 71 isolates of two genera of entomopathogens, and , and a biostimulative genus , for their ability to infect yellow mealworms () and to stimulate maize () growth. Fungal origin, host, and isolation methods were taken into account in virulence analysis as well. Isolates (1154) and (2121) showed the highest mortality (100%) against . High virulence seems to be associated with fungi isolated from wild adult mycosed insects, meadow habitats, and Lepidopteran hosts, but due to uneven sample distribution, we cannot draw firm conclusions. (2882) and (2883) increased shoot length, three isolates (2691, 2693, and 2688) increased root length and two isolates (2146 and 2794) increased plant dry weight. Considering both criteria, the isolate (2693) was the best as it caused the death of 73% larvae and also significantly increased maize root length by 24.4%. The results warrant further studies with this isolate in a tri-trophic system.

Background: Severe acute respiratory syndrome coronavirus 2 was found first in Wuhan and declared a pandemic by the World Health Organization. Coinfection with other respiratory viruses may occur, complicating the diagnosis and treatment of coronavirus disease 2019 . Herein, we identified a Karolinska Institute polyomavirus Stockholm 60 present in a nasopharyngeal swab of a patient with severe acute respiratory syndrome coronavirus 2 infection using next-generation sequencing with an enrichment method.

Trogocytosis is a dynamic cellular process characterized by the exchange of the plasma membrane and associated cytosol during cell-to-cell interactions. Unlike phagocytosis, this transfer maintains the surface localization of transferred membrane molecules. For example, CD4 T cells engaging with antigen-presenting cells undergo trogocytosis, which facilitates the transfer of antigen-loaded major histocompatibility complex (MHC) class II molecules from antigen-presenting cells to CD4 T cells.

Background: Despite the relatively low infection rate following transperineal prostate biopsy (TPB), it remains unresolved whether periprocedural antibiotic prophylaxis (PAP) can be omitted. Our aim was to compare infectious complications (genitourinary infections/GUI, fever, sepsis, readmission rate, 30-day-mortality) following TPB, considering all studies of varying levels of evidence that enable a direct comparison between patients with and without PAP.
Methods: We performed a comprehensive search in PubMed/Medline, Embase, Web of Science, and Cochrane databases, as well as grey literature sources, to identify reports published until January 2024.
Environmental microbial reservoir influences the bacterial communities associated with Hydra oligactis.

The objective to study the influence of microbiome on host fitness is frequently constrained by spatial and temporal variability of microbial communities. In particular, the environment serves as a dynamic reservoir of microbes that provides potential colonizers for animal microbiomes. In this study, we analyzed the microbiome of Hydra oligactis and corresponding water samples from 15 Hungarian lakes to reveal the contribution of environmental microbiota on host microbiome.

The heparan sulfate (HS)-rich extracellular matrix (ECM) serves as an initial interaction site for the homotrimeric spike (S) protein of SARS-CoV-2 to facilitate subsequent docking to angiotensin-converting enzyme 2 (ACE2) receptors and cellular infection. More recent variants, notably Omicron, have evolved by swapping several amino acids to positively charged residues to enhance the interaction of the S-protein trimer with the negatively charged HS. However, these enhanced interactions may reduce Omicron's ability to move through the HS-rich ECM to effectively find ACE2 receptors and infect cells, raising the question of how to mechanistically explain HS-associated viral movement.
