Citrobacter freundii is a species of facultative anaerobic Gram-negative bacteria of the family Enterobacteriaceae which currently consists of 13 recognized species. These bacteria have a rod shape with a typical length of 1–5 μm. Most C. freundii cells have several flagella used for locomotion, although some non-motile taxa do not.
Vibrio vulnificus is a species of gram-negative, motile, curved rod-shaped (bacillus), pathogenic bacteria of the genus Vibrio.Present in marine environments such as estuaries, brackish ponds, or coastal areas, V. vulnificus is related to V. cholerae, the causative agent of cholera. [7]
Infections of a Citrobacter species has a mortality rate between 33–48%, with infants and immunocompromised individuals being more susceptible. [ 4 ] Enterobacter are motile, flagellated bacilli known for causing infections such as bacteremia , respiratory tract infections, urinary tract infections , infections of areas where surgery occurred ...
The species C. amalonaticus, C. koseri, and C. freundii can use citrate as a sole carbon source. Citrobacter species are differentiated by their ability to convert tryptophan to indole (C. koseri is the only citrobacter to be commonly indole-positive), ferment lactose (C. koseri is a lactose fermentor), and use malonate.
The mortality rate is also unknown, but has been observed to be as high as 44%. [34] ... Citrobacter spp 1,840 1,340 411 2,170 2,300 2,510 10,571 Enterobacter spp 5320
Species within the Enterobacterales order are the most common cause of Gram-negative bacteremia, including the species Escherichia coli, Klebsiella pneumoniae, Serratia marcescens, Citrobacter freundii (PMID12913767) and Enterobacter hormaechei (PMID15306996). Early treatment with antibiotics is critical to reduce mortality, but antibiotic ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3]
