Two full-genome sequences of porcine circovirus type 3 (PCV3) are reported. The genomes were recovered from pooled serum samples sows who had just delivered litters with variable numbers stillbirths. two circular (PCV3-BR/RS/6 and PCV3-BR/RS/8) 2,000 nucleotides long contain open reading frames (ORFs) oriented in opposite directions that encode the putative capsid (Cap) replicase (Rep) proteins. intergenic region contains a stem-loop motif, as reported for other circoviruses. Rolling circle...
This study is focused on the identification of faecal virome healthy chickens raised in high-density, export-driven poultry farms Brazil. Following high-throughput sequencing, a total 7743 de novo-assembled contigs were constructed and compared with known nucleotide/amino acid sequences from GenBank database. Analyses blastx revealed that 279 (4 %) related to eukaryotic viruses. Viral genome (total or partial) indicative members recognized viral families, including Adenoviridae,...
A study was conducted to investigate the serum virome of sows with and without stillbirths after farrowing. Sera from at least one stillbirth or normal litters were collected immediately Viral DNA extracted pools submitted high throughput sequencing. No differences in proportion virus-related reads found both groups (p > 0.05). variety viral genomes identified, mostly representative three families: Anelloviridae, Circoviridae Smacoviridae. Besides, a number novel unclassified circular...
Campylobacteriosis is one of the most common types bacterial gastroenteritis affecting humans, and poultry considered a major source causative organism, Campylobacter spp. Broilers may arrive contaminated at slaughterhouses, transport crates could be potential contamination. Thus, cleaning disinfection procedures are crucial to avoid cross-contamination among flocks. Despite its public health importance in Latin American countries, virulence factors jejuni remain poorly studied this region....
Wild birds carry a number of infectious agents, some which may have pathogenic potential for the host and others species, including humans. Domestic pigeons (Columba livia) are important targets study since these increasingly cohabit urban spaces, being possible spillover sources pathogens to In present study, two genomes (PiGyV_Tq/RS/Br PiGyV_RG/RS/Br), representative Gyrovirus genus, family Anelloviridae, were detected in sera free-living collected Southern Brazil. The exhibit less than...
Since its first identification in 2016, porcine circovirus 3 (PCV3) has been detected healthy and/or diseased swine many countries worldwide. In a previous study by our group, PCV3 was sera of sows which had at least one stillborn piglet the last parturition. As such, it became important to investigate if presence sows' could be associated occurrence stillbirths. With that aim, frequency infections and viral DNA loads investigated through real-time quantitative PCR 89 serum samples just...
In the present study, complete nucleotide sequence of porcine circovirus 3 (PCV3) recovered from wild boars lymph nodes is described. The full genome was named PCV3-wb/Br/RS and comprises 2,000 nucleotides with two open reading frames (ORFs) a stem-loop motif in intergenic region. ORFs are oriented opposite directions encode putative capsid (Cap) replicase (Rep) proteins. Based on amino acid analysis, as well most sequences classified PCV3b. Phylogenetic analysis including 97 PCV3 available...
Salmonella Enteritidis and Typhimurium are responsible for causing huge economic loses in aviculture, as they lead young broiler chicks to develop clinical disease thus increase mortality. Salmonella's pathogenicity is considered complex multifactorial, demanding more studies that could elucidate the interaction between host pathogen. The present study aims evaluate virulence of 130S. isolates 70S. inoculated one-day-old through establishment a index. For each strain, 10 commercial from Cobb...
Este estudo forneceu subsídios para o melhor entendimento das intoxicações pelos anti-inflamatórios não esteroidais (AINES) em humanos e animais de companhia. Os principais focos foram a diferença espécie-específica os serviços prestados por Centros Informação Toxicológica. Para tanto, utilizados dados referentes às AINES pessoas, cães gatos reportadas ao CIT/RS entre 2005 2009. Além disso, abordados, comparativamente, do American Association of Poison Centers (AAPCC) 2004 2008, bem como as...
Bovine alphaherpesvirus 1 (subtypes 1.1, 1.2a, and 1.2b), type 5 5a, 5b, 5c), bubaline herpesvirus (BuHV-1) induce highly, though not fully cross-reactive serological responses. Most types subtypes of these viruses circulate particularly in countries the southern hemisphere, notably Brazil Argentina. Therefore, detection infected animals is important defining prevention control strategies, when flocks are destined for international trade. Identification herds most often achieved by assays...
Over the last decade, viral metagenomics has been established as a non-targeted approach for identifying viruses in stock animals, including pigs. This led to identification of vast diversity small circular ssDNA viruses. The present study focuses on investigation eukaryotic Rep-encoding single-stranded (CRESS) DNA genomes serum commercially reared pigs from southern Brazil. Several CRESS were detected, representatives families Smacoviridae (n=5), Genomoviridae (n=3), Redondoviridae (n=1),...
A piometra é uma afecção do sistema reprodutor feminino, mediada por hormônios e secundária a infecções bacterianas, que está presente em todas as espécies de animais domésticos. Pode ser classificada aberta ou fechada, sendo esta forma mais grave. Este trabalho tem objetivo realizar revisão bibliográfica acerca da cadelas quanto ao conceito, classificações, ocorrência, fisiopatologia, agentes etiológicos, sinais clínicos, diagnósticos diferenciais, diagnóstico tratamento. O estudo caráter...
A população de animais domésticos tem um constante crescimento, em destaque encontra-se a gatos, que teve crescimento maior do cães, no Brasil, 2021. Isso se deve as mudanças ocorridas na forma vida humana nos últimos anos. preocupação com saúde dos felinos ganhado atenção devido à proximidade os humanos. Dentre diversas condições acometem felinos, destaca-se anemia, caracterizada por ser uma incapacidade distribuição oxigênio aos tecidos corpo redução quantidade eritrócitos circulantes ou...
A doença periodontal (DP) é uma alteração de grande importância na saúde dos cães, sendo relatado algum grau dessa a partir cinco anos idade. Este estudo tem como objetivo avaliar diferentes graus através da análise prontuários odontológicos cães atendidos região Serra Gaúcha. De acordo com os resultados obtidos, 56% pacientes avaliados possuíam oclusão dentária normal, e 44% possuía do tipo III (prognatismo), em sua maioria braquicefálicos. 41,8% apresentavam DP leve, 39,6% moderada 18,6%...
