TL;DR: In this article , the authors assessed the current global CPV-2 molecular phylogeny and analyzed genetic diversity and temporal spreading of variants from Brazil using a total of 284 CPV2 whole-genome sequences (WGS) and 684 VP2 complete genes.
7 citations
TL;DR: In this article , a novel PCV3-associated clinical disease in piglets from Brazil was described, and the main feature was multisystemic vasculitis characterized by lymphocytes and plasma cells infiltrating and disrupting the wall of vessels, lymphohistiocytic interstitial pneumonia, myocarditis, and encephalitis.

TL;DR: Sequence analysis of partial segments showed that the Influenza D virus is phylogenetically divergent from previously described IDVs from other continents, which can be a first step toward investigating IDV infections in cattle in Brazil and surrounding countries in which the beef industry is economically important.
3 citations
TL;DR: In this article , an outbreak of visna-maedi occurred in Southern Brazil in sheep with clinical signs of blindness and stumbling gait, including heavy noncollapsed lungs and multifocal yellow areas in the cerebral white matter, affecting mainly the periventricular region.
3 citations
TL;DR: In this article , phylogenetic and evolutionary analyses of cattle pestivirus (BVDV-1, 2 and HoBiPeV) originating in Brazil were used to investigate the temporal diversification of subgenotypes in the country.

TL;DR: In this article, a multivariate analysis for visualization of VN results was used to analyze the antigenic relationships between US vaccine strains and field isolates from Switzerland, Italy, Brazil, and the UK.

TL;DR: Through the molecular detection of N. caninum in the cerebrospinal fluid, it was possible to report what appears to be the first case of non-communicating hydrocephalus and microcephaly in an ovine fetus infected with N. caninum.
Abstract: A case of non-communicating hydrocephalus and microcephaly in a sheep fetus infected with Neospora caninum from Lages, Santa Catarina, Brazil, is reported. Macroscopically, there was moderate flattening and narrowing of the skull, and the portion of the cerebral hemispheres was markedly reduced in size, measuring 3.5 × 3.5 × 0.5 cm, with marked diffuse flattening of the brain gyri and dilation of the lateral ventricles. Cerebrospinal fluid samples were positive to N. caninum detection by PCR. Histologically, there was discrete focal lymphoplasmacytic necrotising encephalitis on the floor of the lateral ventricle, discrete multifocal gliosis and discrete multifocal lymphoplasmacytic myositis. Through the molecular detection of N. caninum in the cerebrospinal fluid, it was possible to report what appears to be the first case of non-communicating hydrocephalus and microcephaly in an ovine fetus infected with N. caninum.
TL;DR: In this paper , the white-winged vampire bat (Diaemus youngi) was found to have three complete and 10 nearly complete circular virus genomes were closely related to gemykrogvirus (Genomovirus family), smacovirus (Smacoviridae family), and torque teno viruses (TTVs) (Anellovirus).
Abstract: In the Neotropical region, the white-winged vampire bat (Diaemus youngi) is the rarest of the three species of vampire bats. This bat species feeds preferentially on bird blood, and there is limited information on the viruses infecting D. youngi. Hence, this study aimed to expand the knowledge about the viral diversity associated with D. youngi by sampling and pooling the lungs, liver, kidneys, heart, and intestines of all animals using high-throughput sequencing (HTS) on the Illumina MiSeq platform. A total of three complete and 10 nearly complete circular virus genomes were closely related to gemykrogvirus (Genomoviridae family), smacovirus (Smacoviridae family), and torque teno viruses (TTVs) (Anelloviridae family). In addition, three sequences of bat paramyxovirus were detected and found to be closely related to viruses reported in Pomona roundleaf bats and rodents. The present study provides a snapshot of the viral diversity associated with white-winged vampire bats and provides a baseline for comparison to viruses detected in future outbreaks.
