Citrobacter Isolates youngae isolates were obtained from patients and food samples from 2007 to 2011 in Maanshan Anhui Province, China. Among these 62 isolates, 18 C. youngae and two C. freundii isolates were obtained from diarrheal patients.
What is the genus of Citrobacter Freundii?
Citrobacter
Citrobacter freundii/Genus
Is Citrobacter Youngae pathogenic?
Citrobacter have also been found to cause meningitis, septicemia, and pulmonary infections in neonates and young children, and some of these cases have been linked to contaminated batches of PIF. Citrobacter is considered an opportunistic pathogen.
Where is Citrobacter from?
These organisms are found in soil, water, intestinal tract of animals, and in human clinical samples. Members of the genus Citrobacter are gram-negative, non-sporing rods belonging to family Enterobacteriaceae and, as the name suggests, usually utilize citrate as a sole carbon source.
How do you get Citrobacter?
Citrobacter species are commonly found in water, soil, food, and the intestinal tracts of animals and humans. Many Citrobacter infections are nosocomially acquired; however, they can also be community acquired. A large surveillance study demonstrated that 0.8% of Gram-negative infection was caused by Citrobacter spp.
What does Citrobacter cause?
Citrobacter normally cause urinary tract infections, blood stream infections, intra abdominal sepsis, brain abscesses, and pneumonia and other neonatal infection 6, such as meningitis, neonatal sepsis, joint infection or general bacteremia 7.
What does Citrobacter Freundii cause?
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].
What is the morphology of Citrobacter Freundii?
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. Most C. freundii cells generally have several flagella used for locomotion, but some do not and are non-motile.
What are the symptoms of Citrobacter?
Projectile vomiting • Seizures. Peritonitis and tunnel infection due to Citrobacter freundii have also been reported. This has most frequently been seen in hospitalized and immune-compromised patients who have been kept on ventilators and urinary catheter.
What diseases does Citrobacter Freundii cause?
What are the symptoms of Citrobacter Koseri?
koseri in NICUs resulting in sepsis and meningitis, septic arthritis, and skin and soft tissue infections. Other focal infections in neonates caused by Citrobacter species include bone, pulmonary, and urinary tract infections [147].
Where is Citrobacter freundii in humans?
Citrobacter freundii is isolated from human and animal feces, as well as from extraintestinal specimens. It is also commonly found in soil water and food. Citrobacter diversus is a rare but important agent of neonatal meningitis and infections in compromised hosts.
How many species are there in the genus Citrobacter?
SoJLie Arens, Jan Krhaegen and Ludo Krbist Department of Microbiology, University Hospital St Rafael, Leuven, Belgium Objective: Recently a publication of Brenner et al. introduced 11 genetically distinct species within the genus Citrobacter.
Is Citrobacter motile or anaerobic?
Key words: Identification, differentiation, susceptibility, Citrobacter The genus Citrobacter consists of Gram-negative, facultative anaerobic, motile bacilli with growth on Simmons citrate medmm (hence its name). These bacilli are commonly found in water, soil, food and the intestinal tracts of animals and humans.
What are the possible sources of Citrobacter infection?
Citrobacter are found in a variety of environmental sources, including soil and water, and in the human intestines. They are rarely the primary source of illness, though some strains can cause infections of the urinary tract, sepsis, and infant meningitis. Citrobacter species are not regarded as significant etiological agents in human disease.
Are citrobacteria important opportunistic pathogens in the US hospital population?
Conclusions: These findings suggest that citrobacteria are important opportunistic pathogens contributing to coloniza- tion or infection in our hospital population. Key words: Identification, differentiation, susceptibility, Citrobacter
