Special Issue Information

Dear Colleagues,

This Special Issue’s main focus is enteric and respiratory viruses which cause severe and acute diarrhea and pneumonia in animals and birds, especially in agricultural and veterinary industries. Enteric and respiratory viruses include mainly coronaviruses, rotaviruses, caliciviruses, adenoviruses, herpesviruses, pestiviruses, paramyxoviruses, and orthomyxoviruses. Diarrhea and pneumonia lead to the deterioration of health, insufficient body weight gain, and the death of young animals and birds, resulting in huge economic losses. However, the available information is still limited regarding enteric and respiratory viruses in animals and birds, and hence, there are few effective strategies for the control and prevention of enteric and respiratory viruses, despite their significant economic impact. Therefore, this Special Issue welcomes all types of manuscripts (e.g., reviews, research articles, and short communications), including novel findings with respect to diagnostic approaches, experimental techniques, molecular epidemiology, pathogenicity, host–virus interactions, and the treatment and control methodology of enteric and respiratory viruses.

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.

Bovine torovirus (BToV) is an enteric pathogen that may cause diarrhea in calves and adult cattle, which could result in economic losses due to weight loss and decreased milk production. This study aimed to report the presence, the genetic characterization and the evolution of BToV in calves in Uruguay. BToV was detected in 7.9% (22/278) of fecal samples, being identified in dairy (9.2%, 22/239) but not beef (0.0%, 0/39) calves. BToV was detected in both diarrheic (14%, 6/43) and non-diarrheic (13.2%, 5/38) dairy calves. In addition, BToV was detected in the intestinal contents of 14.9% (7/47) of naturally deceased dairy calves. A complete genome (28,446 nucleotides) was obtained, which was the second outside Asia and the first in Latin America. In addition, partial S gene sequences were obtained to perform evolutionary analyses. Nucleotide and amino acid substitutions within and between outbreaks/farms were observed, alerting the continuous evolution of the virus. Through Bayesian analysis using BEAST, a recent origin (mid-60s) of BToV, possibly in Asia, was estimated, with two introductions into Uruguay from Asia and Europe in 2004 and 2013, respectively. The estimated evolutionary rate was 1.80 × 10−3 substitutions/site/year. Our findings emphasize the importance of continued surveillance and genetic characterization for the effective management and understanding of BToV’s global epidemiology and evolution. Full article
