Pestivirus infections in ruminants result significant economic losses worldwide. The aetiological agents are three species from the genus Pestivirus, family Flaviviridae, including bovine viral diarrhoea virus type 1 (BVDV-1), BVDV-2, border disease (BDV), and an atypical pestivirus named HoBi-like pestivirus. In this study, eighty-nine isolates that were collected Brazil between 1995 2014 originated either cattle, fetal serum (FBS) or as cell culture contaminants genotyped based on a...
Ruminant pestiviruses can infect cattle populations worldwide and cause significant economic losses due to their impact on productivity health. Knowledge of pestivirus diversity is important for control programs vaccine development determining probable sources infection. In this paper, we describe a search ruminant with RT-PCR in sera 9078 calves from 6 12 months age. The were first analyzed pools then individually. Thirty-three positive animals detected (0.36%) 6.9% (24) the 346 herds....
A infecção causada pelo vírus Influenza (IAV) é endêmica em suínos no mundo inteiro. O surgimento da pandemia de influenza humana A/H1N1 (pH1N1) 2009 levantou dúvidas sobre a ocorrência deste Brasil. Durante o desenvolvimento um projeto pesquisa do suína 2009-2010, na Embrapa Suínos e Aves (CNPSA), foi detectado rebanho Santa Catarina, Brasil, surto altamente transmissível causado subtipo viral H1N1. Este causou uma doença leve crescimento fêmeas adultas, sem mortalidade. Tres leitões...
Viruses from the genus Pestivirus of family Flaviviridae have a non-segmented, single-stranded RNA genome and can cause diseases in animals order Artiodactyla. Homologous recombination is rarely reported this virus family. To detect possible events, all complete pestivirus genomes that are available GenBank were screened using distinct algorithms to genetic conversions incongruent phylogenies. Three putative recombinant viruses derived different subtypes/genogroups detected: Bovine viral...
Bovine viral diarrhea virus (BVDV) belongs to the Pestivirus genus, which is further divided into subgenotypes (1a–1u and 2a–c). When persistent infection occurs, calf will be immunotolerant BVDV possibly develop mucosal disease. This study describes an outbreak of BVDV-1d–induced disease lacking intestinal lesions. Eleven calves presented with anorexia, sialorrhea, lameness, recumbency, death. Three were necropsied, showing ulceration interdigital skin oral nasal mucosa; linear ulcers in...
Influenza D virus has been detected predominantly in cattle from several countries. In the United States, regional and state seropositive rates for influenza have previously reported, but little information exists to evaluate national seroprevalence. We performed a serosurveillance study with 1,992 bovine serum samples collected across country 2014 2015. found high overall rate of 77.5% nationally; varied 47.7% 84.6%. Samples Upper Midwest Mountain West regions showed highest rates....
Consumption of energy‐dense/high‐fat diets is strongly and positively associated with overweight obesity, which are increase in the prevalence certain chronic diseases. We evaluated effect hypercaloric/fat or normocaloric on some biochemical parameters rats. Seventy‐two rats were divided into four groups that fed for 16 weeks diets: [9.12% soy oil, oil (NSO)], hypercaloric olive [43.8% (HOO)], saturated fat fat, (HSF)] (NSF)]. HSF consumed more calories daily than others gained...
The ruminant pestiviral species BVDV-1, BVDV-2 and BDV, along with the putative HoBi-like, may cause substantial economic losses in cattle, sheep goats. Brazil's large size, variable biomes wide range of animal production within different geographic regions suggest that presence prevalence pestivirus differ by Brazil. This study investigated genetic diversity pestiviruses determined frequency active infections two states Northeast Region Brazil, Maranhão Rio Grande do Norte. Serum samples...
Major depression is more prevalent among women than men, and progesterone might be involved in the mechanisms that generate these differences. Progesterone clinically used for several reproductive events, but its antidepressant effect unclear. Animal studies showed interference of on depressive behaviors rodents, they are inconclusive, no study compared different treatment durations. This investigated low doses male female rats under acute or chronic administration. Male Wistar phases...
Hepatitis E virus (HEV) is the causative agent of acute hepatitis worldwide. There no seroprevalence study in backyard farms, which are characterized by suboptimal hygienic conditions Brazil. We aimed to determine and genetic diversity HEV pigs Swine serum samples collected 2012 (n=731) 2014 (n=713) were analysed. The presence anti-HEV immunoglobulin G pig was evaluated indirect enzyme-linked immunosorbent assay. Reverse transcription polymerase chain reaction performed phylogenetic analyses...
The HoBi-like pestivirus (HoBiPeV), currently classified as Pestivirus H species, is a pathogen associated with broad spectrum of clinical manifestations in ruminants, particularly cattle. Since HoBiPeV complete genome sequencing data scarce, the present study we described five nearly new Brazilian genomes and further perform more genetic evolutionary characterization all additional sequences available GenBank database. Entropy selection pressure analysis showed E2 gene, surface...
The Pestivirus genus comprises species that affect animal health and productivity worldwide. Members of the Suidae family are hosts for classical swine fever virus (CSFV), an important pathogen tracked by World Organization Animal Health (OIE). However, also susceptible to other pestivirus can result in disease or compromise CSFV detection. We searched infection sera collected from 320 backyard pig herds southern Brazil. used reverse-transcription PCR primers Bungowannah virus; atypical...
ABSTRACT: Bovine mastitis is the most common disease in dairy cattle and responsible for economic losses milk industry. The present study aimed to identify main species evaluate antimicrobial susceptibility of bacterial isolates from cow herds with farms southern Brazil. A total 107 samples were collected different one important producing region Brazil, including located ten cities Northeast Rio Grande do Sul state. Bacterial strains isolated submitted presumptive identification by classical...
Hepaciviruses (HVs) have been detected in several domestic and wild animals present high genetic diversity. The actual classification divides the genus Hepacivirus into 14 species (A-N), according to their phylogenetic relationships, including bovine hepacivirus [Hepacivirus N (HNV)]. In this study, we confirmed HNV circulation Brazil sequenced whole genome of two strains. Based on current HCV, which is divided genotypes subtypes, analysed all available sequences GenBank database proposed an...
