T613 0-6 Sentence denotes 3.6.5.
T614 7-12 Sentence denotes Chile
T615 13-111 Sentence denotes The backyard productive systems (BPS) for raising swine, cattle, and poultry are popular in Chile.
T616 112-388 Sentence denotes A molecular investigation reported a negative active IAV infection across 113 BPS units within ten counties in Chile during 2012–2014 but the serological investigation detected IAV antibodies in swine at two BPS units which suggested a past exposure of swine to the IAV [332].
T617 389-552 Sentence denotes Interestingly, the HA gene sequence of an H12 virus was obtained from a domestic Muscovy duck at one of the BPS which appeared to have originated from a wild bird.
T618 553-641 Sentence denotes This suggested a spillover of the IAV from wild reservoir to the domestic poultry [332].
T619 642-797 Sentence denotes Another study reported the prevalence of H1N2 virus in swine reared at 40 different BPS having poultry and swine in El Yali wetland during 2013–2014 [333].
T620 798-951 Sentence denotes One more study identified four swine sera samples (4/64; 6.3%) that were found positive for IAV antibodies collected from different BPS in Central Chile.
T621 952-1055 Sentence denotes One pool of swine nasal swab samples (1/39; 2.6%) was also detected IAV positive with real-time RT-PCR.
T622 1056-1191 Sentence denotes Interestingly, 7.9% chicken, 4.3% ducks and 11.1% geese samples collected from 329 BPS in Central Chile also had active IAV infections.
T623 1192-1314 Sentence denotes The breeding practice of poultry and swine in the BPS was determined to be a major risk factor for IAV transmission [334].
T624 1315-1512 Sentence denotes Briefly, the IAV strains of H1N1, H1N2, H3N2, and A(H1N1)pdm09 viruses have been reported from the swine in Argentina and Brazil while A(H1N1)pdm09 virus was reported in swine in Colombia and Peru.
T625 1513-1576 Sentence denotes Swine in Chile were found infected with H1N2 virus (Figure 4F).
T626 1577-1704 Sentence denotes In summary, total 281 research articles were identified which reported several influenza viruses in swine populations globally.
T627 1705-1885 Sentence denotes The highest number of studies were reported from Asia (n = 107), followed by North America (n = 76), Europe (n = 55), South America (n = 21), Africa (n = 18) and Australia (n = 4).
T628 1886-2017 Sentence denotes The highest number of reports per country were documented in United States (n = 40) followed by China (n = 39) and Canada (n = 24).
T629 2018-2104 Sentence denotes Until February 2020, influenza viruses have been reported from 53 countries worldwide.
T630 2105-2240 Sentence denotes Four subtypes of IAV including H1N1, H1N2, H3N2, and A(H1N1)pdm09 viruses were most frequently detected in swine populations (Table 1).
T631 2241-2538 Sentence denotes Most of the large-scale studies used serological investigations including ELISA, hemagglutinin inhibition (HI), neuraminidase inhibition (NI), virus neutralization (VN), or microneutralization (MN) assays for the determination of the seroprevalence and subtyping of the influenza viruses in swine.
T632 2539-2625 Sentence denotes Several investigations used virus isolation for the confirmation and subtyping of IAV.
T633 2626-2773 Sentence denotes Most of the virological investigations used one-step real-time RT-PCR and/or reverse-transcription PCR for influenza virus detection and subtyping.
T634 2774-2972 Sentence denotes Sanger sequencing or next-generation sequencing using MiSeq or Ion Torrent sequencing successfully generated the influenza virus sequences from the swine samples for epidemiological interpretations.
T635 2973-3173 Sentence denotes Histological examinations including immunohistochemistry or immunofluorescence were used to examine the swine lung or other internal organ tissue samples for the influenza virus diagnostics (Table 2).
