Abstract: Astrovirus species members of the Mamastrovirus genus (family Astroviridae) have been increasingly recognized as neuroinvasive pathogens in various mammals, including humans, mink, cattle, sheep, and pigs. While cases of astrovirus-associated encephalitis have been reported in North America, Europe, and Asia, their presence has never been documented in the Southern hemisphere. This paper describes a case of astrovirus-associated encephalitis in cattle in Uruguay that broadens the geographic distribution and genetic diversity of neuroinvasive astroviruses and provides phylogeographic evidence of viral introduction to the Americas from Europe. A 22-month-old Holstein steer from a farm in Colonia Department, Uruguay developed progressive neurological signs over a 3-days period before dying. Histopathological examination of the brain and proximal cervical spinal cord revealed disseminated, moderate to severe lymphocytic, histiocytic, and plasmacytic poliomeningoencephalomyelitis with neuronal necrosis. A Mamastrovirus strain in the CH13/NeuroS1 clade, that we called bovine astrovirus (BoAstV)-Neuro-Uy, was identified by reverse transcriptase PCR followed by nearly complete genome sequencing. Additionally, BoAstV was detected intralesionally in the brain by chromogenic RNA in situ hybridization within neuronal perikarya, axons and dendrites. Phylogenetic analysis of BoAstV-Neuro-Uy revealed a close relationship to neurotropic BoAstVs within the Virginia/Human-Mink-Ovine clade, which contains a growing cadre of neuroinvasive astroviruses. Analyzing the complete coding region of neuroinvasive BoAstVs sequences available in GenBank, we estimated an evolutionary rate of 4.27 × 10-4 (95% HPD 2.19?6.46 × 10-4) nucleotide substitutions/site/year. Phylogeographic analysis suggests that the common viral ancestor circulated in Europe between 1794?1940, and was introduced in Uruguay between 1849?1967, to later spread to North America and Japan.

El funcionamiento de la vegetación (ej. intercambio de materia y energía) complementa y mejora las descripciones estructurales de los ecosistemas. Varios de los procesos del funcionamiento de los ecosistemas pueden ser analizados mediante el uso de imágenes de satélite. En este capítulo analizamos el funcionamiento de los pastizales uruguayos utilizando el análisis de series temporales de imágenes de satélite a partir de dos ejemplos. En primer lugar, describimos el funcionamiento de los pastizales naturales de las diferentes unidades geomorfológicas del Uruguay a diferentes escalas espaciales y mostramos cómo esta información puede utilizarse para la definición y monitoreo
de áreas protegidas. En segundo lugar, describimos en forma detallada el funcionamiento de pastizales naturales de una de las áreas de pastizales naturales más extensa del Uruguay (Basalto superficial) y mostramos cómo se puede utilizar esta información para el manejo de sistemas productivos. |
