Abstract

The presence of pseudorabies virus (PrV), porcine parvovirus (PPV) and porcine circovirus 2 (PCV2) was examined in sixty samples (spleen and lymph nodes) and thirty samples of sacral ganglia collected from non-vaccinated swine by virus isolation and polymerase chain reaction (PCR). Using PCR method PrV was detected in three samples, PPV in seven samples and six samples were found positive for PCV2. The phylogenetic analysis of the nucleotide sequences of three PrV isolates identified in this study showed high similarity and significant clustering within the PrV genotype I strains such as Kaplan and Bartha isolated from pigs in Hungary, strain Becker isolated in USA and strain Kolchis isolated in Greece. The nucleotide sequences of two PPV isolates showed high level of similarity with the strain Challenge isolated from pigs in UK, strain Kresse isolated in USA and strains 77 and LZ isolated in China. The phylogenetic analysis of the nucleotide sequences of two PCV2 isolates showed high level of similarity and significant clustering within genotype PCV2b strains such as NIVS-3, NIVS-5 and NIVS-6 isolated in Serbia, strain 3959 isolated in Austria, strain PM165 isolated from pigs in Brasil, and strain XT2008 isolated in China. The results of our study present the molecular characterization of PrV, PPV and PCV2 identified in swine in Republic of Montenegro. Besides that, these results confirmed that PCR is a very useful method for rapid detection of these viruses in subclinically infected swine.

Abstract

The presence of porcine circovirus 2 and porcine parvovirus was examined in forty clinical samples of spleen, lymph nodes and lungs originating from non-vaccinated swine by polymerase chain reaction. All animals were reared in extensive livestock farming systems in different geographical districts of Republic of Srpska, Bosnia and Herzegovina. Porcine circovirus 2 DNA was detected in four lymph node and two spleen samples (15%), while porcine parvovirus DNA was identified in five lymph node samples (12.5%). The presence of both viruses was detected in three lymph node samples (7.5%). Partial nucleotide sequence of ORF1 gene of 2 porcine circovirus 2 and VP2 gene of 2 porcine parvovirus isolates was determined. The nucleotide sequences of two PCV2 isolates from RS-BIH included in phylogenetic typing are similar and cluster together with the strain Mantova isolated from domestic pigs in Italy, strains DE006-14 and DE222-13 isolated from pigs in Germany as well as with the strain Jvnan isolated from pigs in China. Also, analyzed PCV2 isolates were partially similar to the strain NIV-C SRB isolated from pigs in Serbia. The nucleotide sequences of two PPV isolates that were included in phylogenetic typing showed a high level of similarity with the strain Challenge isolated from pigs in UK, strain Kresse isolated from pigs in USA and strains 77 and LZ isolated from pigs in China.

Abstract

Prisustvo svinjskog cirkovirusa 2 i parvovirusa svinja ispitano je u osamdeset zbirnih uzoraka (slezina, limfni čvorovi, pluća) poreklom od nevakcinisanih svinja primenom lančane reakcije polimeraze. Sve životinje su bile iz ekstenzivnog načina gajenja i iz različitih regiona Republike Srpske, BiH. Četiri uzorka limfnih čvorova i dva uzorka slezine su bili pozitivni na prisustvo DNK svinjskog cirkovirusa 2 (7,5%), dok je kod pet uzoraka limfnih čvorova utvrđeno prisustvo DNK parvovirusa svinja (6,25%). U uzorcima poreklom od tri svinje utvrđeno je prisustvo nukleinske kiseline oba prethodno navedena virusa (3,75%). Metodom sekvenciranja određena je nukleotidna sekvenca dela ORF1 regiona genoma svih izolata svinjskog cirkovirusa 2 i dela VP2 gena identifikovanih sojeva parvovirusa svinja. Nukleotidne sekvence virusa PCV2 utvrđene u uzorcima svinja poreklom iz RSBiH uključene u filogenetsku analizu su pokazale visok stepen sličnosti sa nukleotidnim sekvencama soja Mantova izolovanog kod svinja u Italiji, zatim sojeva DE00614 i DE22213 izolovanih kod svinja u Nemačkoj kao i sa sojem Jvnan izolovanog kod svinja u Kini. Istovremeno, virusi PCV2 utvrđeni kod svinja u RSBiH su bili delimično slični sa sojem NIVC SRB virusa PCV2 izolovanim kod svinja u Srbiji. Nukleotidnesekvence svinjskih parvovirusa identifikovanih kod svinja u Republici Srpskoj uključene u filogenetsku analizu su pokazale visok stepen sličnosti sa sojem analognim sekvencama sojeva Challenge izolovanim kod svinja u UK, Kresse izolovanim kod svinja u SADu kao i sa sojevima 77 i LZ izolovanim kod svinja u Kini...
