Organism which is citrate positive indole negative MR negative VP negative sorbitol negative?
The organism is likely to be Escherichia coli. E. coli is citrate positive since it can utilize citrate as a carbon source, but it is indole negative as it does not produce indole from tryptophan. Additionally, E. coli is MR (methyl red) negative and VP (Voges-Proskauer) negative, indicating its fermentation pattern. Lastly, E. coli is typically sorbitol negative, meaning it does not ferment sorbitol.
What test will differentiate between Klebsiella pneumonia and Citrobacter freundii?
Biochemical tests such as indole test and citrate utilization can help differentiate between Klebsiella pneumoniae and Citrobacter freundii. Klebsiella pneumoniae is indole negative and citrate positive, while Citrobacter freundii is indole positive and citrate negative. Additional tests like urease and motility can also aid in differentiation.
What are results of Imvic test on staphylococci?
Staphylococcus epidermidis indole test - negative methyl red - negative voges proskauer test - positive citrate test - no idea

Is staphylococcus epidermidis indole positive?
No, Staphylococcus epidermidis is usually indole negative, meaning it does not produce indole as a byproduct of tryptophan metabolism. This can help differentiate it from other bacteria that are indole positive.
What IMVic results would indicate the presence of fecal coliforms?
The IMViC test results that would indicate the presence of fecal coliforms are negative for indole production, positive for methyl red test, negative for Voges-Proskauer test, and positive for citrate utilization.
Does escherichia coli give a negative result for citrate test?
No, it is present/positive. • Cocci* • Gram-Positive* • Non-motile* • No Capsules* • No Spores* • Facultative Aerobe* • No Glucose, Lactose*, Mannitol* Fermentation • No Urease*, Catalase*, Oxidase*, Ligase*, Protease* Production • Production of Indole*, tryptophonase*
What test will differentiate between Proteus vulgaris and Citrobacter freundii?
Indole test,Proteus vulgaris is be indole positive and Citrobacter freundii will be indole negative
What bacteria is indole negative urea positive methyl red positive hydrogen sulfide positive and lactose negative?
Proteus vulgaris is a bacterium that fits this description. It is indole negative, urea positive, methyl red positive, hydrogen sulfide positive, and lactose negative. These characteristics are used in biochemical tests to help classify and identify different bacteria species.
Biochemical test results for proteus vulgaris?
Biochemical tests commonly used to identify Proteus vulgaris include urease test (positive result), indole test (negative result), motility test (positive result), citrate test (negative result), and carbohydrate fermentation tests (positive results for lactose and sucrose, negative result for glucose). These tests together help in confirming the presence of Proteus vulgaris in a given sample.
What are the IMViC and TSI results for Proteus vulgaris?
IMViC results for Proteus vulgaris are typically indole negative, methyl red positive, Voges-Proskauer negative, and citrate positive. TSI results for Proteus vulgaris show alkaline/alkaline (red/red) slant/butt with no gas production and no hydrogen sulfide production.
Indole positive gram negative bacteria rods?
Indole positive gram negative rod-shaped bacteria include members of the Enterobacteriaceae family such as Escherichia coli and Klebsiella pneumoniae. These bacteria produce indole from the amino acid tryptophan as a metabolic byproduct, which can be detected using the Kovac's reagent test. Indole production is a characteristic used in the identification and differentiation of these bacteria in the laboratory.
