Citrate agar is used to test an organism’s ability to utilize citrate as a source of energy. The medium contains citrate as the sole carbon source and inorganic ammonium salts (NH4H2PO4) as the sole .
The citrate test is performed along with the other IMViC tests to differentiate Gram-negative bacilli of the Enterobacteriaceae family. It is an important test that allows the species-level identification of .Klebsiella aerogenes, previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped .
This test detects those organisms which are capable of utilizing citrate, in the form of its sodium salt, as the sole source of carbon. Organisms capable of utilizing citrate produce alkaline metabolites .
Citrate agar is used to test an organism’s ability to utilize citrate as a source of energy. The medium contains citrate as the sole carbon source and inorganic ammonium salts as the .
The Citrate test is based on the ability of some bacteria to transport and metabolize citrate. When a bacterium possesses the enzyme citrate-permease, it can transport citrate into the cell. . –++ (Enterobacter aerogenes Pattern):- This pattern indicates that the bacterium is positive for Indole production .
Enterobacter aerogenes is a bacterium belonging to the Enterobacteriaceae family, which includes several other important pathogens and opportunistic bacteria. . Citrate Utilization Test: E. aerogenes can utilize citrate as a sole carbon source, turning the Simmons citrate agar from green to blue. Preparation. Dissolve above salts in deionized water. Adjust pH to 6.9. Add agar and Bromothymol blue. Gently heat, with mixing, to boiling until agar is dissolved. Dispense 4.0 to 5.0 ml into 16-mm tubes. . Introduction. Enterobacter is a genus of a common Gram-negative, facultative anaerobic, rod-shaped, non-spore-forming bacteria belonging to the family Enterobacteriaceae.Two of its well- known species, Enterobacter aerogenes and E. cloacae have taken on clinical significance as opportunistic bacteria and have emerged . The urease test is included in the enterotube, see Image 1, chamber 11. Escherichia coli and Enterobacter aerogenes does not normally have the enzyme urease. Proteus vulgaris is a rapid urea splitter, as indicated by the bright purple chamber 11. C. Lysine and Ornithine Decarboxylation Citrate Utilization Test is a biochemical test in the IMViC test series which detects the ability of organisms (bacteria) to utilize citrate as a sole source of energy. It is indicated by the letter “C” of the IMViC. Principle of Citrate Utilization Test. Some bacteria can utilize ‘citrate’ as their sole source of carbon.
IMViC Tests: Principle, Procedure, Results • Microbe Online Enterobacter aerogenes was recently renamed Klebsiella aerogenes.This study aimed to identify differences in clinical characteristics, outcomes, and bacterial genetics among patients with K. aerogenes versus Enterobacter species bloodstream infections (BSI). We prospectively enrolled patients with K. aerogenes or Enterobacter .The media is a semi-solid agar with a colorless dye. As bacteria grow, the dye is reduced by the bacteria and turns red. Bacterial growth is detected by the presence of the red color. 1. Obtain a motility test tube. Use tape to label the tube with your name, your assigned organism and the name of the test media.
Uses. The Malonate Test was originally designed to differentiate between Escherichia and Enterobacter. Its use as a differential medium has now broadened to include other members of Enterobacteriaceae. The malonite reaction can be used todifferentiate among Enterobacteriaceae: Klebsiella pneumoniae is positive (blue at 24 .Klebsiella pneumoniae and Klebsiella oxytoca are the two most frequently encountered Klebsiella species giving rise to infections in humans, but other Klebsiella species can also be found in clinical specimens: Klebsiella ozaenae, Klebsiella rhinoscleromatis, Klebsiella terrigena, Klebsiella planticola, Klebsiella ornithinolytica, and Enterobacter aerogenes . Enterobacter aerogenes. Enterobacter aerogenes phenotypically and genotypically resembles a mobile Klebsiella pneumoniae strain because of its peritrichous, ODC-positive, urease-negative, and indole-negative flagella (Table 1). Izard et al. proposed to reclassify E. aerogenes as Klebsiella under the name Klebsiella mobilis .
The citrate test is a biochemical technique employed to determine a microorganism’s ability to utilize citrate as its sole carbon source for growth. This test is valuable for identifying and differentiating .

This test is valuable for identifying and differentiating .
Inoculate the organism directly onto the surface of a Citrate slant. Incubate aerobically at 35-37°C. Examine for growth and color change after 18-24 hours of incubation. Interpretations. Good growth with the medium color turning blue indicative of Enterobacter aerogenes and Salmonella choleraesuis.Enterobacter usually have a negative methyl-red test, a positive Voges-Proskauer test, can use citrate as a carbon source, can grow in Moller's KCN medium at 30°C, and are ornithine positive, although ‘Enterobacter agglomerans complex’ is ornithine decarboxylase negative (Abbott, 2007). . The E. cloacae-complex and Enterobacter aerogenes .enterobacter aerogenes citrate testThe Gram-negative bacilli of the genera Escherichia, Klebsiella, Enterobacter, Serratia, Citrobacter,and Proteus(Table 26- 1) are members of the normal intestinal flora of humans and animals and may be isolated from a variety of environmental sources. With the exception of Proteus, they are sometimes collectively referred to as the coliform bacilli .
Klebsiella aerogenes (anciennement Enterobacter aerogenes [1]) est une bactérie Gram négative, oxydase -, catalase +, citrate de simmons +, indole -.Elle appartient à la famille des Entérobactéries.C'est un bacille, de 1 à 3 micromètres de longueur, qui peut se déplacer grâce à un ensemble de flagelles [2].(ciliature péritriche).Cette bactérie peut être .
Enterobacter aerogenes is a Risk Group 2 organism and is responsible for nosocomial infection, human and animal diseases and normally present in the gut of vertebrates and also in the environment and thus it may be the organism of concern for on health scheme. Classification of bacterium is as follows-. Kingdom: Bacteria. Phylum: . Figure 3: Citrate test on Escherichia coli and Enterobacter aerogenes. FIG. 3. A negative citrate test result given by Escherichia coli (left) is indicated by a lack of growth and no color change. A positive result given by Enterobacter aerogenes (right) is indicated by growth and a blue color change. (Tasha L Sturm, Cabrillo College, Aptos, CA)
