Eight hundred and thirteen European rodents and shrews encompassing seven different species were screened for alphacoronaviruses using PCR detection. Novel alphacoronaviruses were detected in the species Rattus norvegicus, Microtus agrestis, Sorex araneus and Myodes glareolus. These, together with the recently described Lucheng virus found in China, form a distinct rodent/shrew-specific clade within the coronavirus phylogeny. Across a highly conserved region of the viral polymerase gene, the new members of this clade were up to 22% dissimilar at the nucleotide level to the previously described Lucheng virus. As such they might represent distinct species of alphacoronaviruses. These data greatly extend our knowledge of wildlife reservoirs of alphacoronaviruses.

PEDV is a highly contagious enteric pathogen that can cause severe diarrhea and death in neonatal pigs. Despite extensive research, the molecular mechanisms of host's response to PEDV infection remain unclear. In this study, differentially expressed genes (DEGs), time-specific coexpression modules, and key regulatory genes associated with PEDV infection were identified.

Background: The mucus layer provides the first defense that keeps the epithelium free from microorganisms. However, the effect of the small intestinal mucus layer on pathogen invasion is still poorly understood, especially for swine enteric coronavirus. To better understand virus‒mucus layer‒intestinal epithelium interactions, here, we developed a porcine intestinal organoid mucus‒monolayer model under air‒liquid interface (ALI) conditions.

Bats are presumed reservoirs of diverse coronaviruses (CoVs) including progenitors of Severe Acute Respiratory Syndrome (SARS)-CoV and SARS-CoV-2, the causative agent of COVID-19. However, the evolution and diversification of these coronaviruses remains poorly understood. Here we use a Bayesian statistical framework and a large sequence data set from bat-CoVs (including 589 novel CoV sequences) in China to study their macroevolution, cross-species transmission and dispersal.

Respiratory viruses are among the most common causes of human infections. Examining pathological processes linked to respiratory viral infections is essential for diagnosis, treatment strategies, and developing novel therapeutics. Alterations in oxidative stress levels and homeostasis are significant processes associated with respiratory viral infections.
