BANA test

The BANA test (referring to the <a href="/facts/Enzyme/DSI1Fh7y">enzymatic</a> <a href="/facts/Chemical_breakdown/4X3oxvhb">breakdown</a> of N-benzoyl-dl-arginine-2-napthylamide is used to determine the <a href="/facts/Proteolysis/GtQdv6J7">proteolytic activity</a> of certain oral <a href="/facts/Anaerobe/bhQnlqCq">anaerobes</a> that contribute to <a href="/facts/Halitosis/8RGDp13v">oral malodor</a>. Some <a href="/facts/Bacterium/wC8xSCsU">bacteria</a>, e.g. Prophyromona gingivalis, <a href="/facts/Treponema_denticola/zBf3fvT2">Treponema denticola</a>, and <a href="/facts/Tannerella_forsythia/FLHo9zyY">Bacteroides forsythus</a> (Red complex) produce waste products that are quite odiferous, and as a result contribute to bad breath.
When a sample of a <a href="/facts/Patient/b0SWyyVD">patient's</a> <a href="/facts/Saliva/gK4nvayc">saliva</a> that contains these bacteria is placed within the BANA testing compound, it causes the breakdown of the N-benzoyl enzyme. As a result of this <a href="/facts/Biodegradation/d1UW4dfR">biodegradation</a> occurs, the test compound changes color, indicating a positive reaction.
Uses: Used to identify volatile Sulphur compounds in halitosis patients.
