outbreak of nosocomial infections due to extended-spectrum beta-lactamase-producing strains of enteric group 137, a new member of the family enterobacteriaceae closely related to citrobacter farmeri and citrobacter amalonaticus.a member of the enterobacteriaceae initially identified as kluyvera cryocrescens by the microscan gram-negative combo 13 panel caused an outbreak of nosocomial infections in four patients (pneumonia, n = 2; urinary tract infection, n = 1; wound infection, n = 1) and urinary tract colonization in one patient. when the strains were tested by the enteric reference laboratory of the centers for disease control and prevention, biochemical results were most compatible with yersinia intermedia, kluyver ...200011060050
role of citrobacter amalonaticus and citrobacter farmeri in dissimilatory perchlorate reduction.the article deals with the novel physiological function of dissimilatory perchlorate reduction by strains jb101 and jb109 isolated from a laboratory-enriched mixed consortium originating from a sewage treatment facility. the biochemical and physiological data of the strains showed good correspondence with members of the family enterobacteriaceae. the partial 16s rdna sequence of the strains jb101 and jb109 had similarity of 99.8% to citrobacter amalonaticus and 98% to citrobacter farmeri, respec ...200415069667
isolation and characterization of enteric bacteria from the hindgut of formosan termite.the formosan subterranean termite, coptotermes formosanus shiraki, is an aggressive, invasive termite species that has caused billions of dollars of damage across the united states for the past 50 years. termites depend on intestinal microorganisms for cellulose digestion. symbiotic microorganisms in the termite gut play key physiological functions such as cellulose and hemicellulose digestion, acetogenesis, hydrogenesis, methanogenesis, sulfate reduction, and nitrogen fixation. additionally, in ...200515978992
bacteremia due to citrobacter braakii: a case report and literature review.among the citrobacter genus, the most commonly isolated bacteria from human specimens are citrobacter freundii and citrobacter koseri, and previous cases of infection due to citrobacter braakii have been rarely reported. we present a case of bacteremia due to c. braakii in a 38-year-old woman with cervical cancer. she was admitted to our hospital with complaints of a fever, chills, and nausea. blood culture results showed gram-negative bacilli identified as c. braakii via matrix-assisted laser d ...201627553069
analysis of bacterial diversity during the fermentation of inyu, a high-temperature fermented soy sauce, using nested pcr-denaturing gradient gel electrophoresis and the plate count method.the diversity of bacteria associated with the fermentation of inyu, also known as black soy sauce, was studied through the nested pcr-denaturing gradient gel electrophoresis (dgge) of samples collected from the fermentation stages of the inyu production process. the dgge profiles targeted the bacterial 16s rdna and revealed the presence of citrobacter farmeri, enterobacter cloacae, enterobacter hormaechei, enterococcus faecium, klebsiella pneumoniae, pantoea agglomerans, salmonella enterica, ser ...201323200659
bacteria associated with piezodorus guildinii (hemiptera: pentatomidae), with special reference to those transmitted by feeding.the redbanded stink bug, piezodorus guildinii (westwood) (hemiptera: heteroptera: pentatomidae), is a rapidly growing pest damaging southern us agriculture. pentatomid stink bugs are known to vector bacterial, fungal, and viral plant diseases. however, bacteria associated with redbanded stink bugs and their vector potential have not yet been assessed. in this study, we 1) cultured and identified bacteria transmitted by feeding of redbanded stink bug and 2) described bacteria from guts of redband ...201728025221
citrobacter bitternis sp. nov. isolated from this study, we reported two gram-negative bacteria that were isolated from bitterns, designated as skku-tp7(t) and skku-tp20, representing a novel species of citrobacter. based on the 16s rrna gene sequences, the two strains were found to be closely related and showed the highest pairwise similarity with citrobacter farmeri cdc 2992-81(t) (97.1-97.3 %) and other citrobacter species. cellular fatty acid analysis revealed that the profiles of strains skku-tp7(t) and skku-tp20 were similar to th ...201525833091
identification and functional characterization of arylamine n-acetyltransferases in eubacteria: evidence for highly selective acetylation of 5-aminosalicylic acid.arylamine n-acetyltransferase activity has been described in various bacterial species. bacterial n-acetyltransferases, including those from bacteria of the gut flora, may be involved in the metabolism of xenobiotics, thereby exerting physiopathological effects. we characterized these enzymes further by steady-state kinetics, time-dependent inhibition, and dna hybridization in 40 species, mostly from the human intestinal microflora. we report for the first time n-acetyltransferase activity in 11 ...200111344150
citrobacter farmeri bacteremia in a child with short-bowel syndrome.a case of sepsis in a pediatric patient due to the newly described citrobacter species c. farmeri is described. factors predisposing this child to infection included short-bowel syndrome requiring total parenteral nutrition.19979399558
fatal citrobacter farmeri meningitis in a patient with nasopharyngeal cancer.we describe the case of an adult male with nasopharyngeal carcinoma who had meningitis caused by citrobacter farmeri. the isolate was confirmed as c. farmeri by two commercial identification systems and 16s rrna gene analysis. the patient developed multiorgan failure and died despite antibiotic treatment with in vitro active agents (ceftriaxone and meropenem).201020181904
cloning, expression and characterization of a cold-adapted endo-1, 4-β-glucanase from citrobacter farmeri a1, a symbiotic bacterium of reticulitermes labralis.many biotechnological and industrial applications can benefit from cold-adapted eglcs through increased efficiency of catalytic processes at low temperature. in our previous study, citrobacter farmeri a1 which was isolated from a wood-inhabiting termite reticulitermes labralis could secrete a cold-adapted eglc. however, its eglc was difficult to purify for enzymatic properties detection because of its low activity (0.8 u/ml). the objective of the present study was to clone and express the c. far ...201627843715
classification of citrobacteria by dna hybridization: designation of citrobacter farmeri sp. nov., citrobacter youngae sp. nov., citrobacter braakii sp. nov., citrobacter werkmanii sp. nov., citrobacter sedlakii sp. nov., and three unnamed citrobacter genomospecies.dna relatedness studies (hydroxyapatite method) were done on 112 strains of citrobacteria. by using the recommended definition of a genomospecies 11 genomospecies were identified in the genus citrobacter. these genomospecies were separable by their biochemical profiles. citrobacter koseri (citrobacter diversus) and citrobacter amalonaticus proved to be homogeneous species, as previously described. c. amalonaticus biogroup 1, as described by farmer et al. (j. clin. microbiol. 21:46-76, 1985), was ...19938240948
biochemical identification of new species and biogroups of enterobacteriaceae isolated from clinical 1972 there were only 11 genera and 26 species in the family enterobacteriaceae. today there are 22 genera, 69 species, and 29 biogroups or enteric groups. this paper is a review of all of the new organisms. it has a series of differential charts to assist in identification and a large chart with the reactions of 98 different organisms for 47 tests often used in identification. a simplified version of this chart gives the most common species and tests most often used for identification. the so ...19853881471
