T437 135-298 Sentence denotes The histopathology confirmed the bronchitis in the deceased swine and a strain of IAV designated as “S/Manitoba/647/67” was characterized using IAV antisera [234].
T438 299-442 Sentence denotes The first report of H1N1 virus in Canadian swine appeared in Quebec during 1980s–1990s when five genotypes of H1N1 virus were identified [235].
T439 443-564 Sentence denotes Since then several studies have reported H1N1, H1N2 and H3N2 viruses in Canadian swine [236,237,238,239,240,241,242,243].
T440 565-747 Sentence denotes Another study reported nine isolates of swine influenza viruses with an antigenic variant from the sick swine having proliferative pneumonia in Quebec, Canada during 1990–1991 [244].
T441 748-909 Sentence denotes In a retrospective diagnosis, only one formalin-fixed paraffin embedded swine lung tissue collected during 1991 was found IAV positive with immunohistochemistry.
T442 910-1041 Sentence denotes This investigation suggested that immunohistochemistry can be useful in retrospective diagnosis of the swine influenza virus [245].
T443 1042-1222 Sentence denotes The broncho-intestinal pneumonia in lung tissues of dead swine was reported on a swine farm which exhibited disease symptoms including coughing, weight loss, and labored breathing.
T444 1223-1428 Sentence denotes Interestingly, before the onset of the disease symptoms, this farm conducted a routine serological surveillance of influenza virus which identified H1N1 virus in only one of the twelve swine samples [246].
T445 1429-1551 Sentence denotes Following this surveillance, a three-month old swine from the same farm was found positive for avian influenza virus H4N6.
T446 1552-1612 Sentence denotes The complete genome of this H4N6 virus was reported in 1999.
T447 1613-1683 Sentence denotes This was the first ever report of an avian-origin H4N6 virus in swine.
T448 1684-1927 Sentence denotes The proximity of the swine farm to a natural lake where several wild bird species including waterfowls which were reported to visit frequently might be the reason behind the introduction of this avian influenza virus strain to the swine [246].
T449 1928-2084 Sentence denotes Later three avian-origin H3N3 influenza virus isolates were recovered from swine in eastern Ontario exhibiting weight loss and coughing during October 2001.
T450 2085-2193 Sentence denotes On a nearby farm located approximately 30 kms away, another H3N3 virus isolate was recovered from the swine.
T451 2194-2262 Sentence denotes There was no recorded movement of the swine between these two farms.
T452 2263-2366 Sentence denotes Since these were avian-origin H3N3 viruses hence the role of birds in transmission cannot be ruled out.
T453 2367-2516 Sentence denotes Later, on a third farm, where an influenza like disease had been affecting mainly the nursery piglets, an H1N1 virus was recovered in May 2002 [247].
T454 2517-2731 Sentence denotes Reassortant H1N1 and H1N2 viruses were detected in swine nasal swab or lung tissue samples obtained from three-week old piglets and sows exhibiting typical influenza-like symptoms in Ontario during 2003–2004 [248].
T455 2732-2902 Sentence denotes First triple-reassortant (avian/classical swine/human triple-reassortant) H3N2 viruses from four swine and one human nasal samples were identified in Ontario during 2005.
T456 2903-3106 Sentence denotes The phylogenetic analysis determined that all the virus sequences were 100% identical to each other which apparently emerged from triple-reassortant H3N2 viruses reported in US based swine in 1988 [249].
T457 3107-3266 Sentence denotes One more report of triple-reassortant H3N2 (trH3N2) viruses appeared on the swine farms located in Saint-Hyacinthe, Assomption and Saint-Foy during early 2009.
T458 3267-3414 Sentence denotes The trH3N2 viruses identified in this study were determined to be closely related to North American/Canadian trH3N2 viruses reported earlier [250].
T459 3415-3618 Sentence denotes Later A(H1N1)pdm09 and H1N1 viruses having internal genes of triple reassortant H3N2 virus were reported in swine in four provinces including Manitoba, Alberta, Saskatchewan and Quebec during 2009 [251].
T460 3619-3768 Sentence denotes The first evidence of A(H1N1)pdm09 virus in Canadian swine appeared in 2009 after the human workers at a swine farm developed influenza-like illness.
T461 3769-3881 Sentence denotes The investigation identified that two farm workers along with 56 swine were positive for the A(H1N1)pdm09 virus.
T462 3882-3957 Sentence denotes Transmission of A(H1N1)pdm09 virus from human to swine was suggested [252].
T463 3958-4095 Sentence denotes The same year 17 more swine were detected with A(H1N1)pdm09 virus after a respiratory disease outbreak hit the Alberta swine farms [253].
T464 4096-4257 Sentence denotes A reverse zoonotic transmission of A(H1N1)pdm09 virus to swine from a human subject who visited Mexico and returned to the swine farm was reported in April 2009.
T465 4258-4421 Sentence denotes As a result, ten swine having severe disease were sacrificed for necropsy which identified lesions in the bronchioles corresponding to the influenza virus disease.
T466 4422-4487 Sentence denotes Virus isolation and sequencing identified the A(H1N1)pdm09 virus.
T467 4488-4660 Sentence denotes Additionally, A(H1N1)pdm09 virus was identified in two more human subjects who were exposed to the swine hence indicated the occurrence of zoonoses on the swine farm [254].
T468 4661-4765 Sentence denotes Later during summer 2009, ten more A(H1N1)pdm09 viruses from five swine herds in Manitoba were reported.
T469 4766-4884 Sentence denotes Virus shedding was observed up to 20 days post-infection after the appearance of the clinical symptoms in swine [255].
T470 4885-5116 Sentence denotes This observation was in agreement of a previous report which documented the experimental infection of swine in the laboratory and determined that virus shedding occurs until 11th day after appearance of the clinical symptoms [256].
T471 5117-5281 Sentence denotes Another investigation reported nine A(H1N1)pdm09 and four H3N2 viruses after an influenza-like disease outbreak on a Quebec based swine farm in December 2010 [257].
T472 5282-5577 Sentence denotes The effect of microclimatic conditions on the transmission dynamics of swine IAV in the barns was studied which observed that high relative humidity in the environment during summer months suppresses the aerosol transmission of the droplets which in turn decreases the transmission of IAV [240].
T473 5578-5850 Sentence denotes The high relative humidity in the environment would facilitate the generation of larger droplets which do not tend to shrink easily and hence are less likely to be aerosol transmitted to a longer distance as they fall on the ground quickly after their formation [240,258].
T474 5851-5937 Sentence denotes As a result, a lower transmission of IAV is observed usually during the summer months.
T475 5938-6056 Sentence denotes On the contrary, the IAV transmission increases during winter months when relative humidity is relatively lower [258].
