Seroprevalence and genetic characteristics of five subtypes of influenza A viruses in the Chinese pig population: A pooled data analysis

Inferring patterns of influenza transmission in swine from multiple streams of surveillance data

“…Similar values for sows of varying ages were obtained for pig-dense European countries during a 2002-2003 survey with 85.2 per cent seroprevalence in Germany and 94 per cent in Belgium [24]. A recent survey of influenza prevalence in other Asian countries showed mean levels of virus isolation and seropositivity similar to our results for Hong Kong [21,25]. We conclude that the epidemiology of swine influenza in southern China is broadly consistent with available data from other industrialized countries worldwide.…”

“…Our model provides robust inference of epidemiological parameters, smoothing anomalous data and imputing missing data based on mechanistic assumptions. Multiple modes of surveillance are commonly conducted in parallel, and other studies could benefit from similar joint analyses of these data streams [25,[30][31][32]. In practice, sampling design is very important when applying this idea, because all data streams need to be sampled at the same time points, from the same population.…”

A Unique Sugar-binding Site Mediates the Distinct Anti-influenza Activity of Pig Surfactant Protein D

“…The strong antiviral activity of SP-D in pigs against IAV is intriguing, because pigs serve as a reservoir of H1, H3, H5, H7, and H9 subtype IAVs (61). Moreover, co-circulation of different IAVs and persistence of infection readily occur in these animals.…”

Seroprevalence and associated risk factors of important pig viral diseases in Bhutan

“…It is therefore important for regular monitoring, especially at the human-animal interface (Vijaykrishna et al, 2010). The higher seroprevalence of SIV H1N1 in government breeding farms might be associated with high animal densities (Liu et al, 2011). In government breeding pig farms, pigs are kept in large groups when compared to village backyard farms, where pigs are kept in small numbers.…”
