Abstract. Citrobacter freundii is one of the most important nosocomial opportunistic pathogens, which causes sepsis, as well as different gross and histopathological lesions .Citrobacter isolates were initially identified as C. koseri or as members of the C. freundii complex or C. amalonaticus group on the basis of indole production, formation of H2S, malonate utilization, and acid production from D-arabitol and adonitol. On the basis of the results of these tests, 68% of the Citrobacter strains were identified as . Citrobacter freundii is one of the most important nosocomial opportunistic pathogens, which causes sepsis, as well as different gross and histopathological lesions in various internal organs in humans and animals, especially dogs and fish. This study aimed to investigate the hematological parameters, immunological responses, and pathological .the C.freundii complex, patternsthatwereidentically matched or that deviated in only one phenotypic property from the idealized profile were identified as belonging to that species.

IMViC Test- Principle, Result Chart, Examples, Uses. IMViC test is a series of four different biochemical tests used in identifying and differentiating bacteria, especially the members of Enterobacteriaceae. Though it can be (and is) used for the identification of any type of bacteria, it is mainly used for identifying Gram-negative bacteria . Biochemical Test and Identification of Proteus mirabilis. Biochemical Test and Identification of Citrobacter freundii. Gelatin Hydrolysis Test – Principle, Procedure, Uses and Interpretation. Biochemical Test and Identification of Bacillus cereus. It is a Gram positive, rod-shaped, aerobic, motile, beta hemolytic bacterium found in soil and .

Citrate + Important, to determine the. ability of bacteria to utilize. sodium citrate as it is the. only source of carbon. H2S + Significant test for. identification of this species. Urease V Useful test, helpful in the. diffe rentiation of genus. Proteus and Citrobacter.

The Citrobacter species, including Citrobacter freundii, are aerobic gram-negative bacilli. Citrobacter freundii are long rod-shaped bacteria typically 1-5 μm in length [1]. Most C. freundii cells are surrounded by many flagella used to move about, but a few are non-motile. Its habitat includes the environment (soil, water, sewage), food, and .Citrobacter freundii and Citrobacter koseri. Citrobacter freundii and Citrobacter koseri can cause urinary tract infections, and are found in wound, respiratory, meningitis, and sepsis. They can cause healthcare-associated infections, especially in pediatric and immunocompromised patients [41]. Third-generation cephalosporins are the choice of .

The development of a brown-red to purple-red color (benzaldehyde reagents) or blue color (cinnamaldehyde reagent) within 20 seconds indicates the presence of indole. A negative test is colorless or slightly yellow. Reporting results. E. coli is indole positive, as are many other Enterobacteriaceae, Vibrio, Aeromonas, Plesiomonas, and Pasteurella. Citrobacter freundii: Yellow slant, yellow butt, gas production; . It is recommended that biochemical, immunological, molecular, or mass spectrometry testing be performed on colonies from pure culture for complete identification. . Caps must be loosened during this test or erroneous results will occur. TSI Agar must be read within .methods for identifying C. freundii, such as culture-based biochemical tests; however, such methods are time- consuming and require a con˛rmatory test 14–16 . erefore, molecular methods such as .Citrate Test: Growth on the medium with color change from green to intense blue is positive and positive bacteria are Klebsiella pneumoniae, Citrobacter freundii, Enterobacter cloacae (a minority of strains gives negative result), Salmonella other than Typhi and Paratyphi A, Serratia marcescens, Proteus mirabilis(a minority of strains gives . In general, the results showed a range of both phenotypes and genotypes among the isolates with some revealing a greater similarity to C. freundii and some to S. enterica, while others were identified as . Citrobacter freundii is a Gram-negative bacterium belonging to the Enterobacteriaceae family. It is commonly found in the environment, including soil, water, and the intestinal tracts of humans and animals. Citrobacter freundii is an opportunistic pathogen, meaning it can cause infections in individuals with weakened immune .citrobacter freundii biochemical test results Biochemical Test and Identification of Citrobacter freundiiCitrobacter isolates were initially identified as C. koseri or as members of the C. freundii complex or C. amalonaticus group on the basis of indole production, formation of H2S, malonate utilization, and acid production from D-arabitol and adonitol. On the basis of the results of these tests, 68% of the Citrobacter strains were identified as . To date, C. freundii detection has been performed using currently available method, such as biochemical tests, culture-based methods, and PCR-based assays 14,16,30,31.
