I'm dissapointed no one knows what strepotylsin-o is it's so cool. Its the coolest thing in science 🤧 strepotlysin-o and s are divine. Still need to study it properly though, not too sure at the moment what it is except I know there's a streptolysin o, streptolysin s and streptolysin. If you're saying sounds like strepsils then I agree. It does.
