1. Phylogenetic characterization of the first Ungulate tetraparvovirus 2 detected in pigs in Brazil
Abstract Ungulate tetraparvovirus 2 (UTV2) , formerly known as porcine hokovirus due to its discovery in Hong Kong, is closely related to a Primate tetraparvovirus (human PARV-4) and Ungulate tetraparvovirus 1 (bovine hokovirus). Until now, UTV2 was detected in European, Asian and North American countries, but its occurrence in Latin America is still unknown

2. Detecção e isolamento de anelovírus em suínos e cultivos celulares. / Detection and isolation of anelloviruses in pigs and in cell lineages
Preliminary studies aiming the identification of possible viral agents associated with the postweaning multisystemic wasting syndrome (PMWS) revealed a possible negative association between TTSuV1 and occurrence of PMWS. Based on this finding was hypothesized that TTSuV1 might be able to inhibit the PCV2 multiplication, preventing the development of PMWS. To

3. Frequência de suínos soropositivos para Salmonella sp. em granjas afetadas em diferentes níveis de severidade pela Síndrome Multissistêmica de Definhamento do Leitão Desmamado= Frequency of Salmonella seropositive pigs in farms affected by different severity levels of the Post-weaning Multisystemic Wasting Syndrome / Frequency of Salmonella seropositive pigs in farms affected by different severity levels of the Post-weaning Multisystemic Wasting Syndrome
Background: The Post-weaning Multisystemic Wasting Syndrome (PMWS) has caused considerable losses due to mortality and wasting of pigs and has been often associated with co-infections with other viral or bacterial agents. At the present time, PMWS is the most important infectious disease syndrome in the Brazilian swine production. With a variety of symptoms,

4. Standardization of enzyme immunoassay (ELISA) for serology, detection and quantification of porcine circovirus type 2 / Padronização de ensaios imunoenzimáticos (ELISA) para sorologia, detecção e quantificação do circovírus suíno 2
Porcine circovirus 2 (PCV-2) is the major causative agent of postweaning multisystemic wasting syndrome (PMWS) and is associated with different syndromes that affect the swine. The term PCVAD (Porcine circovirus associated diseases) was introduced in 2006 to gather many diseases. Since serological studies are essential for monitoring the virus, the aim of th

5. Filogeny and filogeografy of porcine circovirus 2 (PCV2), construction and characterization of a recombinant adenovirus that express capsid protein of PCV2 / Filogenia e filogeografia do porcine circovirus 2 (PCV2), construção e caracterização de um adenovírus recombinante que expressa a proteína do capsídeo do PCV2
O circovirus suíno 2 (PCV2) é o principal agente causador da síndrome da postweaning multisystemic wasting syndrome (PMWS) e está associado a diferentes síndromes em suínos. O genoma do PCV2 possui três ORFs principais, sendo a ORF2 a codificadora da proteína do capsídeo. No primeiro estudo, sequências de nucleotídeos da ORF2 de 30 isolados brasil

6. Detecção de possíveis agentes virais associados à circovirose suína. / Detection of possible viral agents associated with postweaning multisystemic wasting syndrome
O Circovirus suíno tipo 2 (PCV2) é um vírus ubíquo que tem sido associado a um número de síndromes em suínos. Entre elas, a Síndrome Multissistêmica do Definhamento dos Suínos (SMDS) tornou-se uma das principais causas de perdas econômicas na suinocultura nacional. No entanto, existe incerteza se o PCV2 é, de fato, o único agente responsável po

7. Relação entre otites bacterianas e infecção pelo circovírus tipo 2 (PCV2) em suínos. / Relationship between bacterial otitis and porcine circovirus type 2 (PCV2) infection in pigs
A Síndrome Multissistêmica do Definhamento do Suíno (SMDS) é uma doença emergente e mundialmente distribuída, que tem trazido sérios prejuízos econômicos para a indústria suinícola. O Circovírus Suíno tipo 2 (PCV2), agente causal da doença, provoca lesões principalmente nos tecidos linfóides, e sugere-se que produza imunossupressão, predispo

8. Nucleotide Sequence of Porcine Circovirus Associated with Postweaning Multisystemic Wasting Syndrome in Pigs
This article describes the nucleotide sequence of a porcine circovirus (PCV) which possesses a high degree of association with postweaning multisystemic wasting syndrome (PMWS), a newly described disease of young pigs. The DNA sequence of this PMWS-associated PCV (pmws PCV) has 68% homology with that of a previously published nonpathogenic strain of PCV. The

9. Detection of Porcine Circovirus Types 1 and 2 in Serum and Tissue Samples of Pigs with and without Postweaning Multisystemic Wasting Syndrome
Presence of porcine circovirus type 1 (PCV1) and PCV2 was studied in sera and superficial inguinal lymph nodes from postweaning multisystemic wasting syndrome (PMWS)-affected and non-PMWS-affected pigs by using in situ hybridization and PCR. PCV1 and PCV2 were found in less than 3% and more than 50% of the samples, respectively. The most sensitive technique

10. Multiplex nested PCR compared with in situ hybridization for the differentiation of porcine circoviruses and porcine parvovirus from pigs with postweaning multisystemic wasting syndrome
Multiplex nested polymerase chain reactions (PCRs) were developed for the simultaneous detection and differentiation of genomic material of porcine circovirus 1 (PCV1), porcine circovirus 2 (PCV2), and porcine parvovirus (PPV) in formalin-fixed, paraffin-embedded tissues. Multiplex conventional and nested PCR and in situ hybridization were compared for their

11. Quantitative, Competitive PCR Analysis of Porcine Circovirus DNA in Serum from Pigs with Postweaning Multisystemic Wasting Syndrome
A competitive PCR (cPCR) assay was developed for monitoring porcine circovirus (PCV) DNA in serum samples from piglets. The cPCR was based on competitive coamplification of a 502- or 506-bp region of the PCV type 1 (PCV1) or PCV2 ORF2, respectively, with a known concentration of competitor DNA, which produced a 761- or 765-bp fragment, respectively. The cPCR

12. Detection of a Novel Strain of Porcine Circovirus in Pigs with Postweaning Multisystemic Wasting Syndrome
Swine infectious agents, especially viruses, are potential public health risks associated with the use of pig organs for xenotransplantation in humans. Therefore, there is a need for better characterization of swine viruses and for the development of diagnostic tests for their detection. We report here isolation of a novel strain of porcine circovirus (PCV)
