Fig 3. Comparison of metabolic profiles of Providencia bacteria as determined by the API 20E test system.

Fig 3

Upper part: Picture of an API20E test result obtained with isolate IO-23 after 48 h of incubation. Reactions are in the same order as indicated in the table below. Lower part: Graphic representation (heat chart) of API20E test results for Tunisian isolate IO-23 and type strains of further Providencia species. Activities indicated in the top row are as follows: beta-galactosidase (ONPG), L-arginine dihydrolase (ADH), L-lysine decarboxylase (LDC), L-ornithine decarboxylase (ODC), citrate utilization (CIT), H2S production (H2S), urease (URE), L-tryptophane desaminase (TDA), indole production (IND), acetoin production (VP), gelatinase (GEL), D-glucose fermentation/oxidation (GLU), D-mannitol fermentation/oxidation (MAN), inositol fermentation/oxidation (INO), D-sorbitol fermentation/oxidation (SOR), L-rhamnose fermentation/oxidation (RHA), D-sacchose/sucrose fermentation/oxidation (SAC), D-melibiose fermentation/oxidation (MEL), amygdalin fermentation/oxidation (AMY), L-arabinose fermentation/oxidation (ARA).
