Cedecea is a genus of extremely rare bacteria of the family Enterobacteriaceae. [1] The name of this genus was derived from CDC, the abbreviation for the Centers for Disease Control where the initial members of this genus were discovered. [2] This genus resembles no other group of Enterobacteriaceae. [3] Cedecea bacteria are Gram-negative, bacillus in shape, motile, nonencapsulated, and non-spore-forming. [4] [5] The strains of Cedecea appear to be similar to those of Serratia . Both Cedecea and Serratia are lipase positive and resistant to colistin and cephalothin; however, Cedecea is unable to hydrolyze gelatin or DNA. [5] [6] [7] [8]

History of genus

Cedecea bacteria were discovered in 1977 by a group of scientists at the CDC and were initially named “Enteric Group 15”. [3] [5] [6] [8] [9] In 1980, Patrick A. D. Grimont and Francine Grimont proposed the genus name of Cedecea for this group. [3] [5] [6] [8] [9] This particular name was given to "Enteric Group 15" for the abbreviation of the Center for Disease Control (CDC) where the group of bacteria was discovered. [3] At this time, six species have been identified. [9] Currently, three strains have been named while three remain unnamed. [3] [9]

Cedecea davisae was named after Betty Davis. Davis is an American bacteriologist who has contributed to serological and biochemical identification of Enterobacteriaceae and Vibrionaceae. [9]

Cedecea lapagei was named after Stephen Lapage, who is a British bacteriologist. Lapage has contributed to bacterial systematics as the editor of Bacteriological Code. Lapage has also made many contributions to the family Enterobacteriaceae. [9]

Cedecea neteri was named after Erwin Neter. Neter is an American microbiologist and physician. Like Davis and Lapage, Neter has contributed to the family Enterobacteriaceae. [9]

Clinical

Cedecea strains are rarely isolated from the environment or living human tissues. [4] [8] However, strains have, at one or more times, been isolated from the following human specimen: sputum, blood, skin wounds, gall bladder, urine and lung tissue. [4] [5] [7] [8] These specimen were collected from a handful of patients who were elderly, medically compromised or immunocompromised. [4] [8] Even though these strains have been isolated, their role in disease and clinical significance is yet to be discovered. [8]

Treatment

Patients who are infected with Cedecea can benefit from antibiotic therapy; however, this can be a challenge due to Cedecea strains being resistant to a range of antimicrobial agents. [4] [5] [8] Cedecea strains are resistant to the following antimicrobial agents: cephalothin, extended spectrium cephalosporins, colistin, and several aminoglycosides. [8]

Ecology

Several members of the Entereobacteriaceae live in the intestines of other organisms, and Cedecea have been isolated in wild tsetse flies and cockroaches. [10] [11] In humans, Cedecea has been located in the blood and saliva, wounds and abscesses, and in ulcerated tissue. [12] [13] The bacteria has been isolated and a limited amount of samples have been taken. Although resistant to several antibiotics, Cedecea - along with several other bacteria - has been shown to be subject to high antibacterial activity from Bovine lactoperoxidase. [14]

<span class="mw-page-title-main">Enterobacteriaceae</span> Family of bacteria

Enterobacteriaceae is a large family of Gram-negative bacteria. It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in the phylum Pseudomonadota. In 2016, the description and members of this family were emended based on comparative genomic analyses by Adeolu et al.

<i>Klebsiella pneumoniae</i> Species of bacterium

Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose-fermenting, facultative anaerobic, rod-shaped bacterium. It appears as a mucoid lactose fermenter on MacConkey agar.

<i>Serratia</i> Genus of bacteria

Serratia is a genus of Gram-negative, facultatively anaerobic, rod-shaped bacteria of the family Enterobacteriaceae. They are typically 1–5 μm in length, do not produce spores, and can be found in water, soil, plants, and animals. Some members of this genus produce a characteristic red pigment, prodigiosin, and can be distinguished from other members of the order Enterobacterales by their unique production of three enzymes: DNase (nucA), lipase, and gelatinase (serralysin). Serratia was thought to be a harmless environmental bacteria until it was discovered that the most common species in the genus, S. marcescens, is an opportunistic pathogen of many animals, including humans. In humans, S. marcescens is mostly associated with nosocomial, or hospital-acquired, infections, but can also cause urinary tract infections, pneumonia, and endocarditis. S. marcescens is frequently found in showers, toilet bowls, and around wet tiles as a pinkish to red biofilm but only causes disease in immunocompromised individuals. Aside from S. marcescens, some rare strains of the Serratia species – S. plymuthica, S. liquefaciens, S. rubidaea, and S. odoriferae – have been shown to cause infection such as osteomyelitis and endocarditis.

<i>Acinetobacter</i> Genus of bacteria

Acinetobacter is a genus of Gram-negative bacteria belonging to the wider class of Gammaproteobacteria. Acinetobacter species are oxidase-negative, exhibit twitching motility, and occur in pairs under magnification.

<i>Enterobacter</i> Genus of bacteria

Enterobacter is a genus of common Gram-negative, facultatively anaerobic, rod-shaped, non-spore-forming bacteria of the family Enterobacteriaceae. Cultures are found in soil, water, sewage, feces and gut environments. It is the type genus of the order Enterobacterales. Several strains of these bacteria are pathogenic and cause opportunistic infections in immunocompromised hosts and in those who are on mechanical ventilation. The urinary and respiratory tracts are the most common sites of infection. The genus Enterobacter is a member of the coliform group of bacteria. It does not belong to the fecal coliforms group of bacteria, unlike Escherichia coli, because it is incapable of growth at 44.5 °C in the presence of bile salts. Some of them show quorum sensing properties.

<i>Elizabethkingia meningoseptica</i> Species of bacterium

Elizabethkingia meningoseptica is a Gram-negative, rod-shaped bacterium widely distributed in nature. It may be normally present in fish and frogs; it may be isolated from chronic infectious states, as in the sputum of cystic fibrosis patients. In 1959, American bacteriologist Elizabeth O. King was studying unclassified bacteria associated with pediatric meningitis at the Centers for Disease Control and Prevention in Atlanta, when she isolated an organism that she named Flavobacterium meningosepticum. In 1994, it was reclassified in the genus Chryseobacterium and renamed Chryseobacterium meningosepticum(chryseos = "golden" in Greek, so Chryseobacterium means a golden/yellow rod similar to Flavobacterium). In 2005, a 16S rRNA phylogenetic tree of Chryseobacteria showed that C. meningosepticum along with C. miricola were close to each other but outside the tree of the rest of the Chryseobacteria and were then placed in a new genus Elizabethkingia named after the original discoverer of F. meningosepticum.

<i>Pantoea</i> Genus of bacteria

Pantoea is a genus of Gram-negative bacteria of the family Erwiniaceae, recently separated from the genus Enterobacter. This genus includes at least 20 species. Pantoea bacteria are yellow pigmented, ferment lactose, are motile, and form mucoid colonies. Some species show quorum sensing ability that could drive different gene expression, hence controlling certain physiological activities. Levan polysaccharide produced by Pantoea agglomerans ZMR7 was reported to decrease the viability of rhabdomyosarcoma (RD) and breast cancer (MDA) cells compared with untreated cancer cells. In addition, it has high antiparasitic activity against the promastigote of Leishmania tropica.

Pluralibacter gergoviae is a Gram-negative, motile, facultatively-anaerobic, rod-shaped bacterium. P. gergoviae is of special interest to the cosmetics industry, as it displays resistance to parabens, a common antimicrobial agent added to cosmetic products.

<i>Cronobacter</i> Genus of bacteria

Cronobacter is a genus of Gram-negative, facultatively anaerobic, oxidase-negative, catalase-positive, rod-shaped bacteria of the family Enterobacteriaceae. Several Cronobacter species are desiccation resistant and persistent in dry products such as powdered infant formula. They are generally motile, reduce nitrate, use citrate, hydrolyze esculin and arginine, and are positive for L-ornithine decarboxylation. Acid is produced from D-glucose, D-sucrose, D-raffinose, D-melibiose, D-cellobiose, D-mannitol, D-mannose, L-rhamnose, L-arabinose, D-trehalose, galacturonate and D-maltose. Cronobacter spp. are also generally positive for acetoin production and negative for the methyl red test, indicating 2,3-butanediol rather than mixed acid fermentation. The type species of the genus Cronobacter is Cronobacter sakazakii comb. nov.

<span class="mw-page-title-main">New Delhi metallo-beta-lactamase 1</span> Enzyme

NDM-1 is an enzyme that makes bacteria resistant to a broad range of beta-lactam antibiotics. These include the antibiotics of the carbapenem family, which are a mainstay for the treatment of antibiotic-resistant bacterial infections. The gene for NDM-1 is one member of a large gene family that encodes beta-lactamase enzymes called carbapenemases. Bacteria that produce carbapenemases are often referred to in the news media as "superbugs" because infections caused by them are difficult to treat. Such bacteria are usually sensitive only to polymyxins and tigecycline.

Staphylococcus nepalensis is a Gram-positive coccoid bacterium belonging to the genus Staphylococcus.

Carbapenem-resistant Enterobacteriaceae (CRE) or carbapenemase-producing Enterobacteriaceae (CPE) are Gram-negative bacteria that are resistant to the carbapenem class of antibiotics, considered the drugs of last resort for such infections. They are resistant because they produce an enzyme called a carbapenemase that disables the drug molecule. The resistance can vary from moderate to severe. Enterobacteriaceae are common commensals and infectious agents. Experts fear CRE as the new "superbug". The bacteria can kill up to half of patients who get bloodstream infections. Tom Frieden, former head of the Centers for Disease Control and Prevention has referred to CRE as "nightmare bacteria". Examples of enzymes found in certain types of CRE are KPC and NDM. KPC and NDM are enzymes that break down carbapenems and make them ineffective. Both of these enzymes, as well as the enzyme VIM have also been reported in Pseudomonas.

Acinetobacter junii is a species of bacteria. Its type strain is ATCC 17908. It can be pathogenic. This bacterium has been linked to nosocomial infections including catheter-related blood stream infections and cellulitis.
