Résumé
Porcine Parvovirus (PPV) is one of the major pathogens responsible for reproductive failure in sows. However, the information on its frequency in the Democratic Republic of Congo (DRC) is largely unknown. Thus, the present study was carried out to detect and genetically characterize some of known Parvovirus namely porcine parvovirus 1, 2, 3, 4, porcine bocavirus (PBoV) 1, and porcine bocavirus-like virus (PBolikeV) in 80 randomly selected archive pig farm samples during an African swine fever (ASF) survey in South Kivu, eastern DRC by polymerase chain reaction (PCR). The majority of animals analyzed (82.5%) were local breeds, and most of them (87.5%) were adults (above one year old). The majority of the animals (65%) were from the free range farms. The PCR result indicated that only PPV3 was detected in 14/80 pigs. Seven swine herds (8.7%) were co-infected with PPV3 and ASFV. Morever, a significantly high PPV3 infection rate was observed in the spleen (66.7%, P<0.0001) compared to the others type of samples. Further, the phylogenetic analysis of partial PPV3 sequences revealed one clade of PPV3 clustered with PPV3 isolates reported in a previous study in Cameroun, China, Slovakia, Germany, and China. This study is the first to report the detection of PPV in DRC. Further studies are needed to assess the levels of PPV3 viremia and the impact in co-infections with other endemic pig viruses, including ASFV.
