Microbiology Does freezing kill flu bacteria?

First of all, the flu is caused by a flu virus, NOT a strain of bacteria and viruses - it's basically a bag of proteins that encapsulate DNA or RNA that can infect cells to hijack the host cell mechanism and initiate host cell immune responses to cause disease. Viruses are generally much more resistant than bacteria, and some of them can withstand temperatures from -20 degrees Celsius to 80 degrees Celsius, so eventually freezing won't work if your goal is to kill the virus. It depends on the conditions. Temperatures above 75 degrees Celsius will completely kill the virus, so this is your best choice.

Bacteria also tolerate cold and drought quite well, through the formation of spores.

@argentum It's quite interesting, can you tell us more about it?

@argentum You mean specific types of bacteria?

@morphism No, this is a common property of bacteria to form spores, at least in the genus Eubacteria

@ekaterina-gribacheva Thanks 😀 

@argentum It implies that bacteria are one of the oldest species in the world.

@morphism This is so, anaerobic bacteria are the first living organisms on our planet.

@argentum Yep))
