Rare experiments explore what leads coronaviruses to spillover from animal reservoirs to humans
Shortly after the COVID-19 pandemic surfaced, researchers at Germany’s Friedrich Loeffler Institute found that SARS-CoV-2 could infect individuals from their long-maintained colony of Egyptian fruit bats, but the virus did not sicken them.It’s not easy to work with captive horseshoe bats, as Linfa Wang discovered.
Critics, including the animal rights group White Coat Waste Project, have assailed the work because of unproven concerns that the COVID-19 pandemic traces back to experiments with bat coronaviruses. Work by Vincent Munster, a virologist who studies bats at NIAID’s Rocky Mountain Laboratories , led to an unsuccessful bid in Congress last month to cut his annual salary to $1.
Cells from cave nectar bats in Linfa Wang’s colony at Duke-NUS Medical School were not susceptible to SARS-CoV-2 in test tube studies.Others are focused on the risks to the bats themselves.
