I'm confused with my interpretations. I did Citrate and OF glucose test last week (TUE) and read the results the next day. I got both negative reaction. When I checked the test tubes this afternoon (MON), the citrate agar turned blue which is positive, and OF glucose turned both yellow meaning Fermenter right?! Now, I'm confused which interpretion do I follow? The 24 hour incubation day or the longer Incubation time? I'm so not a happy camper right now. Thanks for your help. I think it's Proteus.

and also take pictures of models and video rec your professor!

Know where it's found and what it does! I suggest you don't study just the night before the test! Man that's really not going to work!

I checked those websites already. Thanks. I'm down to Shigella and Proteus. Which to choose? I can't fail this one. Help! Please.

and also, whenever i test it for growth, the bacteria floats on top of the liquid media.

Hi everyone! I need your help IDing my unknown. I ran some tests and here are the results: 1. Starch Hydrolysis: positive 2. OF Glucose: negative 3. Fermentation Tube: Glucose: positive, gas negative. Lactose: negative, gas negative. Sucrose: positive, gas negative 4. Citrate: negative 5. Urease: positive, slow 6. Phenylalanine: negative 7. Hydrogen sulfide: negative 8. Motility: negative 9. Ornithine: negative 10. Indole: negative 11. Oxidase: negative. (Although I'm not that sure cause it only turned blue. not pink to blue to black.) 12. Catalase: posiive 13. MRVP: negative 14. Gelatin Hydrolysis: positive 15. Nitrate Reduction: positive I did gram stain it couple of times and its Gram negative rod. Not 100% sure since I'm not that confident. And if you have links it would be highly appreciated.
