It wasn’t greed, or curiosity, that made Li Rusheng grab his shotgun and enter Shitou Cave. It was about survival. During Mao-era collectivization of the early 1970s, food was so scarce in the emerald valleys of southwestern China’s Yunnan province that farmers like Li could expect to eat meat only once a year–if they were lucky. So, craving protein, Li and his friends would sneak into the cave to hunt the creatures they could hear squeaking and fluttering inside: bats. Li would creep into the gloom and fire blindly at the vaulted ceiling, picking up any quarry that fell to the ground, while his companion...

In this study, in-depth passive surveillance comprising nearly 2,500 European swine holdings and more than 18,000 individual samples identified a year-round presence of up to four major swIAV lineages on more than 50% of farms surveilled. Phylogenetic analyses show that intensive reassortment with human pandemic A(H1N1)/2009 (H1pdm) virus produced an expanding and novel repertoire of at least 31 distinct swIAV genotypes and 12 distinct hemagglutinin/neuraminidase combinations with largely unknown consequences for virulence and host tropism. Several viral isolates were resistant to the human antiviral MxA protein, a prerequ...

Pigs are considered as important hosts or “mixing vessels” for the generation of pandemic influenza viruses. Systematic surveillance of influenza viruses in pigs is essential for early warning and preparedness for the next potential pandemic. Here, we report on an influenza virus surveillance of pigs from 2011 to 2018 in...

Dürrwald The genome analysis of 328 H1N1 swine influenza virus isolates collected in a 13-year long-term swine influenza surveillance in Germany is reported. Viral genomes were sequenced with the Illumina next-generation sequencing technique and conventional Sanger methods. Phylogenetic analyses were conducted with Bayesian tree inference. The results indicate continued prevalence of Eurasian avian swine H1N1 but also emergence of a novel H1N1 reassortant, named Schneiderkrug/2013-like swine H1N1, with human-like hemagglutinin and avian-like neuraminidase and internal genes. Additionally, the evolution of an ant...

On 22 June 2020, the International Health Regualtions (IHR) Focal Point (FP) of Brazil shared a preliminary report with the Panamerican Health Organization, the WHO Regional Office for the Americas of a human infection withInfluenza A(H1N2) variant virus (A(H1N2)v). According to the report, the patient, a 22-year-old female, with no comorbidities, worked in a swine slaughterhouse in Ibipor ã Municipality, Paraná State, and developed an influenza-like illness on 12 April 2020. The patient initially sought medical care on 14 April and a respiratory specimen was obtained on 16 April as part of routine surveillan...

AbstractInfluenza A viruses evolve rapidly to escape host immunity. In swine, this viral evolution has resulted in the emergence of multiple H1 and H3 influenza A virus (IAV) lineages in the United States (US) pig populations. The heterologous prime-boost vaccination strategy is a promising way to deal with diverse IAV infection in multiple animal models. However, whether or not this vaccination strategy is applicable to US swine to impart immunity against infection from North American strains of IAV is still unknown. We performed a vaccination-challenge study to evaluate the protective efficacy of using multivalent inacti...

A new study warns that the strain of H1N1, common on China ’s pig farms since 2016, should be “urgently” controlled to avoid another pandemic.
