While everyone else is tussling with the cryptic crossword, I'm completely stuck on one answer in the straightforward Prize Crossword. 19a clue: "Medical term for localised blood-poisoning". T?X?E?I? It obviously wants to be something like TOXESIS ... but there's still a space between the X and the E. I've searched every source I can ... but still don't get the answer. Can anyone come to the rescue please?
