agglutination

Multiple origins. The oldest usage, in relation to tissues adhering or healing in medical contexts, appears in the 16th century, from French agglutination. The linguistic sense derived from this usage during the early 19th century. The sense of gluing or cementing objects together in other contexts is from New Latin agglutinatio, from Latin agglūtinō (“glue; fasten to”) + -iō (a suffix used to form nouns). Compare Spanish aglutinación (“uniting; (linguistic) agglutination”), French agglutiner (“to paste together”, verb), and German Agglutination (“(linguistic) agglutination”) and Agglutinierung (“(biological) adhering, clumping”).

     It may resemble the factor 5 in Salmonella, a heat-labile determinant on the endotoxin molecule which, because of its superficial location, blocks the agglutination reaction of the deeper heat-stable O antigens in the same way as do the Vi and K antigens.
