Bacterial disease (7)
I believe the answer is:
tetanus
'bacterial disease' is the definition.
(I know that tetanus is a type of bacterial disease)
This is all the clue.
(Other definitions for tetanus that I've seen before include "Infection from wound" , "Bacterial disease" , "Attunes to disease from dog-bite" , "Disease causing muscle spasms" , "infectious disease" .)
