Citrobacter freundii complex refers to 8 related species of bacteria from the Genus Citrobacter, including Citrobacter braaki, Citrobacter freundii, Citrobacter gillenii, Citrobacter murliniae, Citrobacter rodenticum, Citrobacter sedlakii and Citrobacter werkmenii. These species all have similar phenotypic and genotypic characteristics, and in most cases cannot be reliably identified using the standard phenotypic methods employed in the laboratory. Therefore the identification for any one of the above species is most accurately reported as "Citrobacter freundii complex" Please see the article entitled "What's in a Name? The Genus Citrobacter" in the related web link. The Genus Citrobacter are part of the family Enterobacteriaceae, which are gram negative enteric (found in the intestinal tract) organisms.
Symptoms of Citrobacter freundii infection in humans can include fever, diarrhea, abdominal pain, and urinary tract infections. In severe cases, it can lead to sepsis or pneumonia. It is important to seek medical attention if experiencing these symptoms.
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.
Enterobacter aerogenes and Citrobacter freundii are both members of the Enterobacteriaceae family. While they share some similarities, they can be differentiated based on their biochemical properties, such as their ability to ferment particular sugars and produce certain enzymes. Clinically, Enterobacter aerogenes is more commonly associated with healthcare-associated infections, whereas Citrobacter freundii is a less frequent cause of infections but is known for its antibiotic resistance.
Yes, Citrobacter freundii is capable of fermenting lactose as it possesses the enzyme beta-galactosidase, which enables the breakdown of lactose into fermentable sugars. This fermentation process can be identified through various biochemical tests used in microbiology.
most citrobacter cells are surrounded by many flagella used to move about but a few are non motile
Yes, Citrobacter freundii can metabolize lactose or citrate as a carbon source.
klebsiella enterobacter citrobacter salmonellaparab
Indole test,Proteus vulgaris is be indole positive and Citrobacter freundii will be indole negative
Citrobacter freundii can be contagious if proper hygiene practices are not followed. It is primarily transmitted through direct contact with contaminated surfaces, hands, or by consuming contaminated food or water. Good hand hygiene and sanitation practices can help prevent the spread of Citrobacter freundii.
Yes, Citrobacter freundii is a facultative anaerobe, meaning it can grow in both aerobic and anaerobic conditions. It can metabolize oxygen if available but can also switch to anaerobic metabolism in the absence of oxygen.
Citrobacter freundii is a Gram-negative bacterium.
Symptoms of Citrobacter freundii infection in humans can include fever, diarrhea, abdominal pain, and urinary tract infections. In severe cases, it can lead to sepsis or pneumonia. It is important to seek medical attention if experiencing these symptoms.
Yes, Citrobacter freundii is a rod-shaped bacterium. It is a Gram-negative, facultative anaerobic bacterium that is commonly found in the environment and in the intestinal tract of humans and animals.
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.

No, Citrobacter freundii is not a spore-forming bacterium. It is a rod-shaped, Gram-negative bacterium commonly found in the environment and in the gastrointestinal tract of humans and animals.
