Article Synopsis
  • Porcine parvoviruses (PPVs) are major contributors to reproductive issues in pigs globally, with eight genetic variants identified across four genera.
  • PPV7, first found in the USA in 2016, has spread to Europe, Asia, and South America, and was detected in pig farms in Italy facing reproductive challenges.
  • In a study conducted in Sardinia, PPV7 was found in 20.59% of domestic and wild pig samples, with higher co-infection rates of Porcine Circovirus 2 and 3 in PPV7-positive pigs, and molecular analysis revealed a high frequency of viral recombination.

Porcine Circovirus type 2 (PCV2) is the etiological agent of a disease syndrome named Porcine Circovirus disease (PCVD), representing an important threat for the pig industry. The increasing international trade of live animals and the development of intensive pig farming seem to have sustained the spreading of PCVD on a global scale. Recent classification criteria allowed the identification of nine different PCV2 genotypes (PCV2a-i).

Porcine respiratory disease complex (PRDC) represents a significant threat to the swine industry, causing economic losses in pigs worldwide. Recently, beyond the endemic viruses PRRSV and PCV2, emerging viruses such as TTSuV, PCV3, and PPV2, have been associated with PRDC, but their role remains unclear. This study investigates the presence of PCV2 and PRRSV and emerging viruses (PCV3, TTSuV, and PPV2) in the lungs of swine belonging to different age groups by histopathology and real-time PCR.

Swine production represents a significant component in agricultural economies as it occupies over 30% of global meat demand. Infectious diseases could constrain the swine health and productivity of the global swine industry. In particular, emerging swine viral diseases are omnipresent in swine populations, but the limited knowledge of the pathogenesis and the scarce information related to associated lesions restrict the development of data-based control strategies aimed to reduce the potentially great impact on the swine industry.
