This is changing due to the increasing amount of newly identified neurotropic astroviruses in cases of nonsuppurative encephalitis and neurological disease in humans, pigs, ruminant species and minks. Neurological cases in ruminants and humans usually occur sporadically and as isolated cases. This contrasts with the situation in pigs and minks, in which diseases associated with neurotropic astroviruses are endemic and occur on the herd level. Affected animals show neurological signs such as mild ataxia to tetraplegia, loss of orientation or trembling, and the outcome is often fatal. Non-suppurative inflammation with perivascular cuffing, gliosis and neuronal necrosis are typical histological lesions of astrovirus encephalitis. Since astroviruses primarily target the gastrointestinal tract, it is assumed that they infect the brain through the circulatory system or retrograde following the nerves. The phylogenetic analysis of neurotropic astroviruses has revealed that they are genetically closely related, suggesting the presence of viral determinants for tissue tropism and neuroinvasion. In this review, we summarize the current knowledge on neurotropic astrovirus infections in animals and propose future research activities.<\/jats:p>","DOI":"10.3390\/v13071201","type":"journal-article","created":{"date-parts":[[2021,6,23]],"date-time":"2021-06-23T21:14:51Z","timestamp":1624482891000},"page":"1201","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Neurotropic Astroviruses in Animals"],"prefix":"10.3390","volume":"13","author":[{"given":"Nicole","family":"Wildi","sequence":"first","affiliation":[{"name":"Division of Neurological Sciences, Vetsuisse Faculty, University of Bern, 3012 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6800-5129","authenticated-orcid":false,"given":"Torsten","family":"Seuberlich","sequence":"additional","affiliation":[{"name":"Division of Neurological Sciences, Vetsuisse Faculty, University of Bern, 3012 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1097\/INF.0000000000002551","article-title":"Epidemiology and Etiology of Severe Childhood Encephalitis in the Netherlands","volume":"39","author":"Bruning","year":"2020","journal-title":"Pediatr.
