What is the morphology of Citrobacter Freundii?
Citrobacter freundii are facultative anaerobic Gram-negative coliform bacteria in the Enterobacteriaceae family. The bacteria are long rod-shaped with a typical length of 1-5 μm.
Is Citrobacter a gram-negative rod?
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.
Is Citrobacter positive or negative?
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.
How do you contract Citrobacter?
MODE OF TRANSMISSION: Citrobacter may be spread by direct contact with hospital staff members, mother to child transmission or through ingestion of environmental sources (fecal-oral route) but person-to-person transmission is more prevalent 7, 11.
What disease is caused by Citrobacter Freundii?
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 antibiotics are used to treat Citrobacter Freundii?
Aminoglycosides (gentamicin, netilmicin, amikacin), fluoroquinolones (levofloxacin, ciprofloxacin), and carbapenems (ertapenem, imipenem, and meropenem) were the most active agents against both C. freundii and C. koseri.
How did I get Citrobacter Freundii?
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.
What are the symptoms of Citrobacter Freundii?
Signs and Symptoms 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.
How can you prevent Citrobacter?
Since several nosocomial outbreaks of Citrobacter infections have been reported and the sources of the organisms have been found to be the gastrointestinal tracts or hands of hospital staff members, infection control measures to prevent person-to-person transmission, such as hand washing, are the most important …
Is Citrobacter Freundii antibiotic resistance?
freundii were collected from may serve as a reservoir for antibiotic resistance. The emergence of multi-drug resistant C. freundii in the environment is an increasing threat to the treatment of bacterial infections.
Where do you get Citrobacter Koseri?
Citrobacter koseri, a facultatively anaerobic, lactose-fermenting, gram-negative bacillus, belongs to the family Enterobacteriaceae. 4 It is commonly found in soil and water, and in the intestinal tracts of animals and humans.
How do you get Citrobacter Freundii?
What is the arrangement 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. Citrobacter freundii. Phylum:
What are the characteristics of a Citrobacter colony?
They usually appear translucent or opaque and gray with a shiny surface and an entire edge. Mucoid or rough strains may occur occasionally. Colonies which slowly ferment lactose can resemble Salmonella colonies on enteric media. Facultatively anaerobic. Chemoorganotrophic, having both a respiratory and a fermentative type of metabolism.
What does Citrobacter spp look like on agar?
Citrobacter spp. grow readily on ordinary media. At 24 hours, colonies on nutrient agar are generally 2-4 millimeters in diameter, smooth, low, convex and moist. They usually appear translucent or opaque and gray with a shiny surface and an entire edge. Mucoid or rough strains may occur occasionally.
What kind of bacteria is a Citrobacter?
The Citrobacter species are aerobic gram-negative bacteria. For starters, most bacteria are classified into two categories: gram-positive bacteria and gram-negative bacteria.
