What is Citrobacter in humans?
Citrobacter organisms are enteric gram-negative rods that are closely related to Salmonella organisms. In humans, Citrobacter species are most often reported as a cause of meningitis in the neonate. Most cases are sporadic, although outbreaks have been described.
What is Citrobacter in dogs?
Citrobacter. Found in water, feces and urine, and not considered to be animal pathogens. The disease is characterized by cutaneous hemorrhage and ulceration, loss of claws and digits, flaccidity and paralysis. Saunders Comprehensive Veterinary Dictionary, 3 ed. © 2007 Elsevier, Inc.
How has the genus Citrobacter changed over time?
The genus Citrobacter has undergone significant taxonomic revision through the use of newer techniques based on DNA relatedness.
How do you identify Citrobacter species?
Culture is the traditional method of detecting Citrobacter spp. which grow well on normal media, are aerobic or facultative anaerobic, ferment glucose, produce catalase, but not oxidase, and are generally lactose-negative or later lactose-fermenting ( Greenwood, 2007 ).

What is the meaning of Citrobacter?
[sit´ro-bak″ter] a genus of gram-negative, facultatively anaerobic, motile, rod-shaped bacteria, which have been associated with diarrhea and secondary infections in debilitated persons, occasionally causing primary septicemia. Species include C.
How do you get Citrobacter infection?
In patient with Citrobacter infections, the bacteria can be transmitted vertically from mother or horizontally from carriers or other hospital sources (14). The infection may occur as sporadic cases or nosocomial outbreaks.
What disease does Citrobacter cause?
Citrobacter koseri (formerly Citrobacter diversus) is best known as the cause of sepsis and meningitis leading to central nervous system (CNS) abscesses in neonates and young infants. Early onset and late-onset infections occur as for other neonatal bacterial infections.
What are the symptoms of Citrobacter?
Citrobacter freundii causes: ➢ Urinary tract infections which triggers: • A burning sensation during • Urination, increased urge to urinate, • Offensive smelling urine, • Scanty urination, • Blood in the urine • Fever • Burning or pain in the lower back and / or pelvis.
Can Citrobacter be cured?
PHYSICAL INACTIVATION: 90% of the Citrobacter organisms may be killed after 15 minutes at 230 MPa 18. Citrobacter are also inactivated by UV, microwave, gamma radiation, moist heat (121°C for at least 20 min) and dry heat (165-170°C for 2 h) 19- 22.
How do you treat Citrobacter infection?
Various types of antibiotics, including amino- glycosides carbapenems, cephalosporins, chloramphenicol and quinolones, are used for the treatment of C. koseri infections. Treatment options can be monotherapy, with agents potentially active against Citrobacter spp. or combination therapy [8].
What antibiotics treat Citrobacter?
Various types of antibiotics, including aminoglycosides carbapenems, cephalosporins, chloramphenicol and quinolones, are used for the treatment of C.
What is Citrobacter UTI?
[1,2] The genus Citrobacter is distinct group of aerobic, gram negative bacilli from the Enterobacteriaceae family, widely distributed in water, soil, food and intestinal tract of man and animals. UTIs caused by Citrobacter species have been described in 5 to 12% of bacterial urine isolates in adults.
How can you prevent Citrobacter?
Probiotics are effective in preventing colonic epithelial cell hyperplasia when given before or concurrently with orogastric challenge with Citrobacter rodentium.
How did I get Citrobacter freundii?
Citrobacter freundii is normally found in water, soil, food, and the intestines of humans and animals. The bacteria was first discovered in 1932 by isolating a pure culture from soil [6]. It is a common component of our gut flora, and many strains are considered “good gut bacteria” and are beneficial.
Is Citrobacter freundii UTI?
freundii infections. Although Citrobacter spp. are less commonly isolated, they are emerging as a common nosocomial multidrug-resistant pathogen, especially in developing countries. UTI caused by Citrobacter spp. have been seen in 12% patients in 1961, and since then, its prevalence has been increasing.
What causes Citrobacter koseri UTI?
C. koseri is a gram-negative, non-lactose fermenting rod that is often part of normal human flora. It causes infections almost exclusively in neonates and infants—primarily meningitis—and in immune-compromised hosts. In the adult patient, the urinary tract is one of the most common sites of infection by Citrobacter.

Overview
- Organisms of the genus Citrobacter are gram-negative bacilli that are occasional inhabitants of the gastrointestinal tract and are responsible for disease in neonates and debilitated or immunocompromised patients. The genus has undergone frequent changes in nomenclature, making it difficult to relate the types identified in reports of newborn disea...

Overview
Citrobacter koseri is a Gram-negative, non-spore-forming bacillus. It is a facultative anaerobe capable of aerobic respiration. It is motile via peritrichous flagella. It is a member of the family of Enterobacteriaceae. The members of this family are the part of the normal flora of human and animal digestive tracts. C. koseri may act as an opportunistic pathogen in a variety of human infections.
