<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">throat</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for gullet that I've seen before include "Passage between pharynx and stomach" , "Food passage in the throat" , "Oesophagus" , "Food-passage from mouth to stomach" , "part of canal" .)
(Another definition for strep that I've seen is " bacterium".)
