The role of Citrobacter in clinical disease of children: review. (1/256)

Various species of Citrobacter may cause infections in neonates and immunocompromised hosts. 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. The majority of cases are sporadic, with no clear source of infection. A few have been confirmed to be vertically transmitted, and nosocomial outbreaks have occurred in neonatal care units. The pathophysiology is not well understood, but a surface protein has been identified as a possible virulence factor among strains that cause citrobacter brain abscesses in neonates. Despite improvements in diagnostic imaging techniques, surgery, and antibiotic therapy, approximately one-third of infants with abscesses die, and one-half sustain CNS damage. In this article, the taxonomy, epidemiology, pathogenesis, diagnosis, treatment, and outcome of citrobacter disease in children are reviewed.  (+info)

Citrobacter rodentium infection in mice elicits a mucosal Th1 cytokine response and lesions similar to those in murine inflammatory bowel disease. (3/256)

Citrobacter rodentium is a classically noninvasive pathogen of mice that is similar to enteropathogenic Escherichia coli (EPEC) in man. Following oral infection of young mice, the organism colonizes the distal colon, and within 1 week the colonic mucosa doubles in thickness and there is massive epithelial cell hyperplasia. Since T-cell responses in mouse models of inflammatory bowel disease (IBD) also cause epithelial hyperplasia, we have investigated the possibility that C. rodentium promotes similar T-cell responses in the mucosa, thereby increasing epithelial shedding, transmission, and replication of the organism. Beginning 6 days after infection, bacteria were observed to be in close association with the epithelial surface and were also visible scattered throughout the lamina propria and in the submucosa. There was a CD3(+)-cell infiltrate into the colonic lamina propria and epithelium as well as mucosal thickening and crypt hyperplasia. The majority of CD3(+) cells were CD4(+) and were not gammadelta+. Reverse transcription-PCR analysis of cytokines also revealed a highly polarized Th1 response (interleukin-12, gamma interferon, and tumor necrosis factor alpha) in the mucosa and a large increase in the epithelial cell mitogen keratinocyte growth factor. None of the changes were seen in mice inoculated with bacteria lacking intimin (which is necessary for colonization), but they were seen in mice inoculated with C. rodentium complemented with intimin from EPEC. This is the first example of a classically noninvasive bacterial pathogen which elicits a strong mucosal Th1 response and which produces pathology similar to that seen in mouse models of IBD, which is also characterized by a strong Th1 response. These results also suggest that the colonic mucosa responds in a stereotypic way to Th1 responses.  (+info)

Biochemical identification of Citrobacter species defined by DNA hybridization and description of Citrobacter gillenii sp. nov. (formerly Citrobacter genomospecies 10) and Citrobacter murliniae sp. nov. (formerly Citrobacter genomospecies 11). (4/256)

Recent work describing six named species and two unnamed genomospecies within Citrobacter has enlarged the genus to 11 species. DNA relatedness and phenotypic tests were used to determine how well these species can be identified. One hundred thirty-six strains were identified to species level by DNA relatedness and then identified phenotypically in a blinded fashion. By using conventional tests, 119 of the 136 strains (88%) were correctly identified to species level. Three additional strains (2%) were identified as citrobacteria but were not identified to species level, and 14 strains (10%) were misidentified as other Citrobacter species. Carbon source utilization tests were used to identify 86 of the strains. Eighty-four strains (98%) were correctly identified, and two strains (2%) were misidentified as other Citrobacter species. Additional strains of Citrobacter genomospecies 10 and Citrobacter genomospecies 11 were identified, allowing these species to be formally named as Citrobacter gillenii sp. nov. and Citrobacter murliniae sp. nov., respectively.  (+info)

Role of bacterial intimin in colonic hyperplasia and inflammation. (5/256)

Enteropathogenic Escherichia coli (EPEC) cells adhere to gut epithelial cells through intimin alpha: the ligand for a bacterially derived epithelial transmembrane protein called the translocated intimin receptor. Citrobacter rodentium colonizes the mouse colon in a similar fashion and uses a different intimin: intimin beta. Intimin alpha was found to costimulate submitogenic signals through the T cell receptor. Dead intimin beta+ C. rodentium, intimin alpha-transfected C. rodentium or E. coli strain K12, and EPEC induced mucosal hyperplasia identical to that caused by C. rodentium live infection, as well as a massive T helper cell-type 1 immune response in the colonic mucosa. Mutation of cysteine-937 of intimin to alanine reduced costimulatory activity in vitro and prevented immunopathology in vivo. The mucosal changes elicited by C. rodentium were interferon-gamma-dependent. Immunopathology induced by intimin enables the bacteria to promote conditions that are favorable for increased microbial colonization.  (+info)

Citrobacter rodentium espB is necessary for signal transduction and for infection of laboratory mice. (6/256)

Citrobacter rodentium is the causative agent of transmissible murine colonic hyperplasia and contains a locus of enterocyte effacement (LEE) similar to that found in enteropathogenic Escherichia coli (EPEC). EPEC espB is necessary for intimate attachment and signal transduction between EPEC and cultured cell monolayers. Mice challenged with wild-type C. rodentium develop a mucosal immunoglobulin A response to EspB. In this study, C. rodentium espB has been cloned and its nucleotide sequence has been determined. C. rodentium espB was found to have 90% identity to EPEC espB. A nonpolar insertion mutation in C. rodentium espB was constructed and used to replace the chromosomal wild-type allele. The C. rodentium espB mutant exhibited reduced cell association and had no detectable fluorescent actin staining activity on cultured cell monolayers. The C. rodentium espB mutant also failed to colonize laboratory mice following experimental inoculation. The espB mutation could be complemented with a plasmid-encoded copy of the gene, which restored both cell association and fluorescent actin staining activity, as well as the ability to colonize laboratory mice. These studies indicate that espB is necessary for signal transduction and for colonization of laboratory mice by C. rodentium.  (+info)

Structural studies of the O-specific polysaccharide of Hafnia alvei strain PCM 1207 lipopolysaccharide. (7/256)

The structure of the O-specific side-chain of the Hafnia alvei strain PCM 1207 lipopolysaccharide (LPS) has been investigated. Methylation analysis, partial acid hydrolysis, matrix-assisted laser-desorption ionization time-of-flight (MALDI-TOF) MS, fast atom bombardment (FAB)-MS/MS and 1H- and 13C-NMR spectroscopy were the principal methods used. Glycerol phosphate was identified as a constituent in the polysaccharide and the following structure of a pentasaccharide repeating unit was established: The polysaccharide is partially (approximately 10%) substituted with O-acetyl groups. The lipopolysaccharide was also subjected to high resolution magic angle spinning (HR-MAS) NMR analysis, which showed both the signals of the O-specific polysaccharide as well as several signals from unsubstituted core oligosaccharides. This confirmed the presence of the described structure in the native LPS.  (+info)

Mono- and Stereopictres of 5.0 Angstrom coordination sphere of Arsenic atom in PDB 3bfd: Crystal Structure of the Class A Beta-Lactamase Sed-G238C Mutant From Citrobacter Sedlakii
Citrobacter is a genus of Gram-negative coliform bacteria in the Enterobacteriaceae family. 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 non-lactose fermentor), and use malonate. Citrobacter shows the ability to accumulate uranium by building phosphate complexes. These bacteria can be found almost everywhere in soil, water, wastewater, etc. They can also be found in the human intestine. They are rarely the source of illnesses, except for infections of the urinary tract and infant meningitis and sepsis. C. freundii strains have inducible ampC genes encoding resistance to ampicillin and first-generation cephalosporins. In addition, isolates of Citrobacter may be resistant to many other antibiotics as a result of plasmid-encoded resistance genes. LPSN ...
A Citrobacter sp. accumulated uranyl ion () via precipitation with phosphate ligand liberated by phosphatase activity. The onset and rate of uranyl phosphate deposition were promoted by , forming NH4UO2PO4, which has a lower solubility product than NaUO2PO4. This acceleration decoupled the rate-limiting chemical crystallization process from the biochemical phosphate ligand generation. This provided a novel approach to monitor the cell-surface-associated changes using atomic-force microscopy in conjunction with transmission electron microscopy and electron-probe X-ray microanalysis, to visualize deposition of uranyl phosphate at the cell surface. Analysis of extracted surface materials by 31P NMR spectroscopy showed phosphorus resonances at chemical shifts of 0·3 and 2·0 p.p.m., consistent with monophosphate groups of the lipid A backbone of the lipopolysaccharide (LPS). Addition of to the extract gave a yellow precipitate which contained uranyl phosphate, while addition of Cd2+ gave a chemical shift

Over a 6-month period, eight strains of Citrobacter diversus (Citrobacter koseri) resistant to extended-spectrum cephalosporins and monobactams were isolated from seven colonized and/or infected patients from the same intensive care unit. All strains harbored a single large conjugative plasmid which mediated an extended-spectrum beta-lactamase of the SHV-4 type (ceftazidimase phenotype; enzyme pI, 7.8; plasmid DNA hybridization with a blaSHV-specific probe). All strains were characterized by antibiotic resistance pattern analysis, beta-lactamase content analysis, plasmid profiling, ribotyping with EcoRI, and arbitrarily primed (AP)-PCR with primers O8 and O12. Among the eight C. diversus strains, strains Cd5 to Cd12, six isolates (isolates Cd6 to Cd11) were identical by all markers; one strain (strain Cd5) differed by two markers (antibiotype and AP-PCR pattern with primer O8), and the remaining strain (strain Cd12) differed by two other markers (ribotype and AP-PCR pattern with primer O12). Our ...
The starting point of this work was the observation of three clinical strains that exhibited a positive double-disk synergy test, resistance to broad-spectrum cephalosporins, and a β-lactamase of pI 7.6. A distinctly higher level of resistance to cefotaxime than to ceftazidime was observed with the transconjugants obtained. However, C. amalonaticus Rio-2, unlike transconjugant TrRio-2, exhibited an ESBL phenotype of the ceftazidimase type. These differences of behavior between the wild-type strain Rio-2 and its transconjugant suggest an additional resistance mechanism directed mainly against ceftazidime in C. amalonaticus Rio-2. A chromosomally mediated cephalosporinase, which has mainly cefotaximase activity, inC. amalonaticus has been previously reported (8), but no β-lactamase of corresponding pI (5.5 and 6.05) was detected in our strain. Decreased permeability might also explain the enhanced resistance to ceftazidime. However, such a mechanism in this species has not been reported.. In the ...
Hardy Diagnostics ColiScreen™ is to be used as a rapid screening test to assist in the identification of E. coli. The performance of a spot indole test alone is not an adequate screen for E. coli, since there are at least 52 species of gram-negative bacilli that grow on MacConkey, are indole-positive, and ferment lactose. The more common ones include Klebsiella oxytoca, Citrobacter freundii, C. sedlakii, C. braakii, C. koserii, C. amalonaticus, C. youngae, Aeromonas hydrophila and Serratia odorifera. The test is designed to be used on isolates demonstrating typical appearance on EMB and/or MacConkey Agar. Although most E. coli exhibit lactose-fermentation on these media, it should be noted that approximately 5% of E. coli are non-lactose-fermenters.(2) Using this test system, glucuronidase-positive, indole-positive, gram-negative organisms are presumptively identified as E. coli.

The role of opportunistic pathogens in infectious pathological conditions of humans is increasingly being appreciated. Some organisms that have been considered nonpathogenic occasionally cause severe hospital infections and outbreaks of acute enteric diseases.
The genera Aerides and Rhynchostylis have often been referred to collectively as the Fox-tail orchids because of their inflorescence characteristics, resembling the tail of a fox notably because of the droop and the conical shape of the raceme. The generic name Aerides, however, is literally translated as Children-of-the-Air. Mr. Aleko Lilius, the American journalist-explorer mentioned earlier, apparently went to Calayan Island in the Babuyan Group north of Luzon, the Philippines, in search of a legendary orchid which the natives called Saguy Yepyep or Flower of the Sacred Sleep. The full story is unclear except from what can be inferred from the remarks of Mr. Lilius when he said, . . . all for the sake of an adventuring journalists foolishly uncommercial respect for pagan traditions about a chieftain and his maiden, whose love gave birth to a rare jungle flower, one of the rarest in the world. The legend, however, produced native worshippers who, in spite of their conversion to ...

The genus Citrobacter was originally distinguished from other members of the Enterobacteriaceae by its ability to use citrate as a carbon source. Citrobacter infection is commonly reported in neonates and immunocompromised patients. Citrobacter koseri, formerly known as Citrobacter diversus, is best known as the cause of sepsis and meningitis leading to central nervous system (CNS) abscesses in neonates and young infants. The majority of cases are sporadic, with no clear source of infection. A significant number of the infants with abscesses die, and many sustain CNS damage. It adults, however, Citrobacter infection with central nervous system involvement is rare, and is usually associated with an underlying disorder. Citrobacter koseri (strain ATCC BAA-895 / CDC 4225-83 / SGSC4696) was isolated in 1983 in Maryland where it caused neonatal meningitis. ...
Immobilized cells of a Citrobacter sp. can remove heavy metals from wastewaters by deposition ofmetals with enzymatically liberated phosphate. Nickel is not removed effectively by this technique, but Ni2+ can be intercalated into cell-bound, crystalline HUO2PO4 previously deposited enzymatically. This technique for efficient removal of Ni from solution has been generically termed microbially enhanced chemisorption of heavy metals(MECHM). The nickel uranyl phosphate deposits bound to Citrobactersp. cells immobilized in polyacrylamide gel (FAG) were analyzed using scanning transmission electronmicroscopy with electron probe X-ray microanalysis (EPXMA) and proton-induced X-ray emissionanalysis(PIXE). Both methods gave the molar ratios of nickel, uranium, and phosphorus in the depositsas close to 1:2:2 in all analyzed parts of the sample. EPXMA proved that the deposits were localized onthe surface of cells inside FAG particles as well as those immobilized on the edge. Small deposits ofnickel uranyl ...

Manual curation resolved these bifurcations and reduced the number of Citrobacter contigs from ∼1,400 to 10 (the largest curated contig is 2.55 Mb) (Fig. 3B). The final contigs are generally syntenous with the Citrobacter 30_2 strain draft genome (Broad Institute, Cambridge, MA) and the complete Citrobacter koseri ATCC BAA-895 genome (Washington University, St. Louis, MO). Consequently, the fragments were oriented and ordered by reference to the C. koseri genome to generate a final genome representation for the dominant strain, UC1CIT-i (Table S6 in Dataset S2). Of the ten genome gaps, eight are the rRNA-encoding regions that could not be resolved, one is within a prophage, and one is in the intergenic region between genes on contig ends that are adjacent in both isolate genomes.. Citrobacter species are facultative anaerobes from the family Enterobacteriaceae and are commonly found as commensals within the mammalian intestinal tract. Like Serratia, they have been frequently documented as ...

Acquired metallo-β-lactamases (MBLs) produced by gram-negative bacteria, including Pseudomonas aeruginosa, Acinetobacter spp., and several enterobacteria, confer resistance to all β-lactams except the monobactams (2). Acquired MBLs are categorized on the basis of amino acid sequences into various types (2, 23). The IMP- and VIM-type enzymes are the most common and are found worldwide (2, 8, 23). Recently, four additional types, SPM, GIM, SIM, and AIM, have been found in Brazil (21), Germany (3), Korea (11), and Australia (24), respectively. We report here on the detection of a novel acquired MBL in a clinical isolate of Citrobacter freundii identified in Japan.. C. freundii strain KHM243 was isolated in 1997 from a patient with catheter-associated urinary tract infection at Kyorin University Hospital (Tokyo, Japan). Escherichia coli K-12 strain W1895 was used as the recipient in conjugation experiments. E. coli JM109 (Takara Bio, Shiga, Japan) was used as the host for recombinant plasmids. ...

Last year, four premature infants died in the intensive care unit for newborns at Ewha Womens University Hospital on the night of Dec.16. All suffered cardiac arrests and died within a two-hour span. The Korean Center for Disease Control and Prevention (KCDC) announced that the same type of Citrobacter freundii bacteria found in the IV nutrition was injected into the infants veins. Lee Hyung-min, head of the infection management department of KCDC, said
Glifosat (po IUPAC-u: N-(fosfonometil)glicin) jest sistemski herbicid širokog spektra, koji se koristi za uništavanje korova, prevashodno jednogodišnjih širokolisnih trava i korova, koje raste uporedo sa komercijalnim i uzgajanim biljnim kulturama širom svijeta. Herbicid je otkrio američki hemičar John E. Franz 1970. godine, uposlenik koncerna Monsanto.[2] Ova kompanija je iste godine stavila glifosat na tržište pod nazivom Roundup. Posljednji komercijalno važniji patent Monsanta u SAD istekao je 2000. godine. Glifosat su ubrzo počeli koristiti farmeri u mnogim zemljama, tim prije što je Monsanto ponudio i sjeme otporno na glifosat, što je uzgajivačima omogućilo uništavanje korova bez uticaja na usjeve. Prema podacima iz 2007. glifosat je bio najčešće korišteni herbicid u oblasti poljoprivrede u SAD (između 820 i 840 hiljada tona godišnje), te drugi najčešći korišteni herbicid (odmah iza 2,4-D) u oblasti industrije, održavanja vrtova, trgovini i državnim ...
The twin-arginine translocation (Tat) system is involved in not only a wide array of cellular processes but also pathogenesis in many bacterial pathogens; thus, this system is expected to become a novel therapeutic target to treat infections. To the best of our knowledge, involvement of the Tat system has not been reported in the gut infection caused by Citrobacter rodentium. Here, we studied the... ...

AU - Dougan, Gordon. PY - 2013/3. Y1 - 2013/3. N2 - MicroRNAs (miRNAs) are small noncoding molecules that control gene expression posttranscriptionally, with microRNA-155 (miR-155) one of the first to be implicated in immune regulation. Here, we show that miR-155-deficient mice are less able to eradicate a mucosal Citrobacter rodentium infection than wild-type C57BL/6 mice. miR-155-deficient mice exhibited prolonged colonization associated with a higher C. rodentium burden in gastrointestinal tissue and spread into systemic tissues. Germinal center formation and humoral immune responses against C. rodentium were severely impaired ...

The objective of this study was to determine the role of OPN in host responses to a non-invasive bacterial pathogen, Citrobacter rodentium, which serves as a murine infectious model of colitis. OPN gene knockout and wild-type mice were infected orogastrically with either C. rodentium or Luria-Bertani (LB) broth. Mouse-derived OPN+/+ and OPN-/- fibroblasts were incubated with C. rodentium and attachingeffacing lesions were demonstrated using transmission electron ...

Enteropathogenic E. coli (EPEC), Enterohaemorhagic E. coli (EHEC) and Citrobacter rodentium are constituent members of the attaching and effacing (A/E) pathogens. The A/E group of bacteria are considered to be extracellular pathogens which form characteristic lesions by intimately adhering to host enterocytes and directing the effacement intestinal brush border. EPEC and EHEC are diarrhoeal pathogens, which are a global health burden in developing and industrialised countries respectively. Citrobacter rodentium is a murine pathogen which is an excellent animal model for EPEC and EHEC infection. EPEC, EHEC and C. rodentium conserve a genomic region termed the locus of enterocyte effacement (LEE) which encodes a type 3 secretion system (T3SS), a core set of type 3 secreted effector proteins and the outer membrane adhesin intimin, which are essential for A/E lesion formation. A/E pathogens utilise their T3SSs to translocate dozens of effector proteins directly from the bacteria into host cells. ...
Scientists at North Carolina State University have discovered a phenomenon never seen before in plants while studying molecular changes inside tree cells as wood is formed.. In research published online in Proceedings of the National Academy of Sciences the week of Aug. 20, the team found that one member of a family of proteins called transcription factors took control of a cascade of genes involved in forming wood, which includes a substance called lignin that binds fibers together and gives wood its strength.. The controller protein regulated gene expression on multiple levels, preventing abnormal or stunted plant growth. And it did so in a novel way.. The controller, a spliced variant of the SND1 family, was found in the cytoplasm outside the cell nucleus. This is abnormal, because transcription factor proteins are always in the nucleus. But when one of the four other proteins in its family group was present, the spliced variant was carried into the nucleus, where it bound to the family ...

To investigate, researchers used a mouse model infected with Citrobacter rodentium, the mouse equivalent of an E. coli infection. Using this model, they saw an increase in the permeability of the intestinal barrier within just two days of infection -- well before inflammation and epithelial damage. In particular, they uncovered a critical role for interleukin-22 that in turn influences another molecule called claudin-2, previously known to be involved in causing diarrhea. They found that diarrhea resulting from the signaling of these two molecules helped promote pathogen clearance and limited disease severity ...
