Special Issue Information

Dear Colleagues,

We are pleased to announce the launch of a Special Issue of Viruses dedicated to the in-depth exploration of the family Caliciviridae. This Special Issue aims to enhance our understanding of this diverse family, which currently encompasses eleven genera. The family Caliciviridae has been detected in a wide range of animals, with seven genera infecting mammals (Lagovirus, Norovirus, Nebovirus, Recovirus, Sapovirus, Valovirus, and Vesivirus), two infecting birds (Bavovirus and Nacovirus), and two infecting fish (Minovirus and Salovirus). Additionally, several unclassified caliciviruses have been identified.

Advancements in metagenomics and novel in vivo and in vitro infection model systems have significantly expanded our understanding of the diversity of the family Caliciviridae and its interactions with host organisms. In recent years, significant progress has been made in understanding the calicivirus life cycle, the biology of infections in humans and animals, epidemiology, and immunity. Notably, new transmission routes have been discovered for noroviruses, as well as genotype-specific differences in virus–host interactions, and ongoing efforts are being made to develop treatment strategies and vaccines to control acute and chronic infections.

Therefore, we invite the submission of various types of manuscripts, including reviews, research articles, and short communications, that explore novel discoveries in the field of calicivirus research. Specifically, we encourage investigations related to epidemiology, evolution, replication, and virus–host interactions, although other relevant topics are also welcome.

We look forward to receiving your contributions to this Special Issue.

Dr. Miranda De Graaf
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Viruses is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Sapovirus (SaV) is a type of gastroenteric virus that can cause acute gastroenteritis. It is highly contagious, particularly among children under the age of 5. In this study, a total of 712 stool samples from children under the age of 5 with acute gastroenteritis were collected. Out of these samples, 28 tested positive for SaV, resulting in a detection rate of 3.93% (28/712). Samples with Ct < 30 were collected for library construction and high-throughput sequencing, resulting in the acquisition of nine complete genomes. According to Blast, eight of them were identified as GI.1, while the remaining one was GI.6. The GI.6 strain sequence reported in our study represents the first submission of the GI.6 strain complete genome sequence from mainland China to the Genbank database, thus filling the data gap in our country. Sequence identity analysis revealed significant nucleotide variations between the two genotypes of SaV and their corresponding prototype strains. Phylogenetic and genetic evolution analyses showed no evidence of recombination events in the obtained sequences. Population dynamics analysis demonstrated potential competitive inhibition between two lineages of GI.1. Our study provides insights into the molecular epidemiological and genetic evolution characteristics of SaV prevalent in the Nantong region of China, laying the foundation for disease prevention and control, as well as pathogen tracing related to SaV in this area.
