Is Citrobacter Freundii Aerobic Or Anaerobic?

Citrobacter freundii (C. freundii) is a motile, facultative anaerobe, non-sporing gram-negative bacilli colonize in the gastrointestinal tract of humans and other animals. It is also found in water, soil, and food.

Is Citrobacter freundii aerobic?

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.

Does Citrobacter freundii ferment?

freundii complex organisms. Citrobacter spp. are gram-negative bacilli in the family Enterobacteriaceae. They ferment glucose and other carbohydrates, are catalase and oxidase positive, and reduce nitrate.

What is Citrobacter freundii known for?

freundii with gastroenteritis, neonatal meningitis, and septicemia. [3] It is known to cause health care associated infections of the urinary tract, respiratory tract, blood, and other normally sterile sites in the body. The chief cause is a weak and attenuated immune system and functioning of the body.

Is Citrobacter freundii coagulase positive or negative?

Citrobacter freundii is a species of facultative anaerobic gram-negative bacteria of the family Enterobacteriaceae. The bacteria have a long rod shape with a typical length of 1–5 μm.

Is Citrobacter Freundii anaerobic?

Citrobacter freundii (C. freundii) is a motile, facultative anaerobe, non-sporing gram-negative bacilli colonize in the gastrointestinal tract of humans and other animals. It is also found in water, soil, and food.

Is Citrobacter Freundii a coliform?

The MF technique indicated that Citrobacter freundii was the most common coliform species in water samples. However, the fermentation tube techniques displayed selectivity towards the isolation of Escherichia coli and Klebsiella.

What is Citrobacter Freundii resistant to?

All isolates were resistant to cefoxitin, and sensitive to imipenem, meropenem and amikacin. The majority of Citrobacter isolates (61.3%) were MDR of three or more antibiotics out of the 22 antibiotics tested. Two C. freundii isolates each carried the bla_TEM−1 gene and a variant of qnrB77.

What is Citrobacter Freundii sensitive to?

An examination of 99 field and reference strains of Citrobacter freundii showed 79% of them to be resistant to cephaloridine and sensitive to carbenicillin, while 96% of 45 field and reference strains of Citrobacter koseri examined were sensitive to cephaloridine and resistant to carbenicillin.

Does Citrobacter Freundii reduce nitrate?

C. freundii reduced nitrate or nitrite stoichiometrically to ammonia. Maximum molar growth yields for nitrate (nitrite) were 15.3 (9.9) g/mol for C.

Does Citrobacter freundii smell?

Citrobacter freundii just smells like nasty. Pseudomonas smells, to some, like grapes. To others it smells like corn chips.

What are the symptoms of Citrobacter freundii?

It can invade and replicate in the brain too. Common clinical features and Citrobacter freundii symptoms include: • high grade fever • projectile vomiting • seizures. peritonitis and tunnel infection due to Citrobacter freundii have also been reported.

Does Citrobacter freundii reduce sulfur?

They mentioned that this strain of Citrobacter is able to reduce sulfate to sulfide. The isolation of bacteria belongs to C. freundii with sulfate reduction capability shows that the diversity of SRB still has the possibility to be expanded (Zhang et al.

Is Citrobacter Freundii a Halophile?
