Pigs can be infected with coronavirus, Canadian-US study finds | South China Morning Post

Findings challenge conclusions from previous research that swine could not contract the pathogen that causes Covid-19

Investigation prompted by similarities between key protein receptor in pig and human cells

A Canadian government study has concluded that pigs can be infected with the coronavirus, challenging previous findings on the pathogen’s reach.
In a non-peer reviewed paper published on Friday, a joint research team from Canada and the United States said Sars-CoV-2, the virus that causes the disease Covid-19, was found in swine tissue about two weeks after infection.

“[This study] provides evidence [that] live Sars-CoV-2 virus can persist in swine for at least 13 days,” the researchers led by Brad Pickering from the Canadian Food Inspection Agency in Winnipeg, Manitoba, said in the paper posted in bioRxiv.org.

The paper comes four months after Chen Hualan, from the Harbin Veterinary Research Institute in northeastern China, reported that a large-scale experiment involving various domestic animals indicated that pigs could not contract Sars-CoV-2.
