capable of causing or promoting agglutination; having the property of making things stick or clump together.
From Latin 'agglutinare' (glue to) plus Greek '-genic' (producing or causing). A medical/immunological term describing substances that trigger clumping.
Certain bacteria are naturally agglutogenic—they express proteins on their surface that make antibodies grip them tightly, which ironically helps the immune system grab them but also helps the bacteria clump protectively together.
