The intruder stalks its prey with stealth and precision, preparing to pierce the armor of its prey. Once inside, the attacker forces his host to produce more intruders, then detonates them, spitting out a multitude of invaders who can continue their rampage on a larger scale.

The drama, depicted in a microscopic video of SARS-CoV-2 infecting bat brain cells, provides a window into how the pathogen turns cells into virus-making factories before causing the death of the host cell.

The video was produced by Sophie-Marie Aicher and Delphine Planas, virologists at the Institut Pasteur in Paris who obtained an honorable mention in microscopy video contest sponsored by Nikon, the photography company.

Filmed for 48 hours with an image recorded every 10 minutes, the footage shows the coronavirus as red spots circulating among a mass of gray spots – the brain cells of the bat. Once infected, the cells of the bat begin to fuse with neighboring cells. At one point, the whole mass bursts, causing the cells to die.

Ms Aicher, who specializes in zoonotic diseases – those that can be transmitted from animals to humans – said this infectious juggernaut is the same in bats and humans, with one important distinction: bats don’t fall ultimately not sick.

In humans, the coronavirus is able to evade detection and cause more damage in part by preventing infected cells from alerting the immune system to the presence of invaders. But its special power is the ability to force host cells to fuse with neighboring cells, a process known as syncytia that allows the coronavirus to go undetected during its replication.

“Anytime the virus has to come out of the cell it is likely to be detected, so if it can pass directly from one cell to another, it can work much faster,” Ms. Aicher said.

She said she hoped the video would help demystify the virus and make it easier for people to understand and appreciate this deceptive foe who has turned billions of lives upside down.

“It’s important to help people get past the scientific jargon to understand that this is a very sophisticated and intelligent virus that is well suited to making humans sick,” she said.
