Slightly off topic but anywho.
When I was about 10 I was bitten by a rat which was running up Vaughan Rd, no doubt from from one the sewers that gushed into the Mersey. It put me in the Victoria Hospital for 3 weeks with 4 shots a day in my arse. They couldn't put a name to what I'd been infected with.
Bubonic Plague, Sandshoes?
