Prevalence of Astroviruses in Different Animal Species in Poland.

Astroviruses (AstVs) are small RNA viruses characterized by a high mutation rate, the ability to recombine, and interspecies transmission, which allows them to infect a multitude of hosts including humans, companion animals, and farmed animals as well as wildlife. AstVs are stable in the environment, and their transmission is usually through the fecal-oral route or via contaminated water and food. Although direct zoonotic transmission was not confirmed, interspecies transmission events have occurred or have been indicated to occur in the past between wild and domestic animals and humans.

[PRIME EDITING - a new method of editing genes].

The Prime Editing method introduces the expected manipulations within a given genome with a Cas9-nicase and pegRNA structure and a reverse transcriptase, which is responsible for the synthesis of the segment, which is then incorporated into the edited strand. This technique is based on the previously discovered CRISPR/Cas9 method. It differs from CRISPR/Cas9 in the absence of double cracks within the DNA helix, which is due to its complex structure, including the presence of additional elements, i.
