Popis
Shrnutí:	A number of newly identified porcine parvoviruses had been described during the last decade, but the presence and prevalence of these viruses are unknown in Hungary and only partly known for Europe. The present study was conducted to detect and measure the prevalence of these viruses, namely porcine parvovirus (PPV) 2, PPV3, PPV4, porcine bocavirus (PBoV) 1, PBoV2, PBo-likeV and the 6V and 7V parvoviruses. The prevalence of PPV1 and porcine circovirus type 2 (PCV2) was also investigated. Faecal samples, blood serum samples, organ tissues, foetuses and semen were collected from different swine herds in Hungary and tested by polymerase chain reaction methods specific for the different viruses. The results indicated that all of the examined parvoviruses were present in Hungary, hence in Europe. The prevalence was 18.1% for PCV2, 0.5 % for PPV1, 6.4% for PPV2, 9.7% for PPV3, 6.4% for PPV4, 1.5% for PBo-likeV, 4.8% for PBoV1 and PBoV2 and 1.8% for 6V and 7V. Based on the analysis of partial PPV4 and PBo-likeV sequences, these viruses showed a high degree of sequence conservation, whereas PPV3 and the majority of PPV2, PBoV1, PBoV2, 6V and 7V sequences showed higher variability. Possible sites of recombination were also identified between PBoV1 and PBoV2 genomes.
