Genetic Analysis and Distribution of Porcine Parvoviruses Detected in the Organs of Wild Boars in Serbia

Abstract Porcine parvoviruses (PPVs) are diverse and persistently evolving viruses found in domestic pigs wild boars. parvovirus 1 (PPV1) causes reproductive problems adult animals, although the veterinary relevance of PPV2, PPV3, PPV4 has not been clarified. The detection sequence analysis PPVs circulating boar populations Serbia was performed to determine their phylogenetic relationships prevalence 122 organ samples collected during 2018. DNA PPV1, PPV3 detected 56.6% examined samples, whilst identified. Overall, most prevalent 69.6% positive followed by PPV1 63.8%, PPV2 21.7% samples. Single infections were more common, concurrent confirmed 34.8% for two, 10.1% three viruses. Sequence showed no significant nucleotide differences from pig strains Europe USA, however separate clustering China NADL-2 strain demonstrated. Examination selected sequences might suggest a certain geographical distribution genetically considering high similarities neighboring countries, variability comparison with other reported different parts world. Wild clustered separately boars, as well original porcine hokovirus strain. It is further noted that circulate amongst Serbian
