Surprise! Snake And Spider Venom Aren't Nearly as Sterile as We Thought - ScienceAlert
Bacteria are resourceful little organisms. They can live in some of the weirdest, most inhospitable places on our planet – arid deserts, toxic acidic lakes, even deep in Earth's crust below the ocean floor. But scientists have just discovered a new, very unexpected habitat for the hardy little microbes: the venom of snakes and spiders. This contradicts what we thought we knew; such venoms contain antimicrobial compounds, which scientists assumed to mean they were sterile environments in which no microbes could thrive. The discovery to the contrary means bacteria that cause infections could already be present in venom before a victim is even bitten, suggesting that anyone bitten by a snake or spider may also need to be treated for infection. "We found that all venomous snakes and spiders that we tested had bacterial DNA in their venom," notes molecular biologist Sterghios Moschos of Northumbria University in the UK. "Common diagnostic tools failed to identify these ...
