| diversity of the phosphoenolpyruvate/glucose phosphotransferase system in the enterobacteriaceae. | the presence of the phosphoenolpyruvate glucose phosphotransferase entry routes was studied in 97 genospecies of enterobacteriaceae. phosphoenolpyruvate(pep)-dependent phosphorylation of alpha-methyl-d-glucoside and 2-deoxyglucose was evidenced in 72 species (group i organisms), suggesting the presence of both the iiglc (formerly ii-bglc/iiiglc) and iiman (formerly ii-b/ii-aman) entry routes. erwinia amylovora, budvicia aquatica and all species of leminorella and proteus (as defined by dna relat ... | 1987 | 3606872 |
| occurrence of gram-negative bacteria in hens' eggs depending on their source and storage conditions. | the aim of this study was to analyse the qualitative composition of gram-negative microbes, mainly of the family enterobacteriaceae, including pathogenic bacteria such as salmonella, in the albumens and yolks and on the shells of hens' eggs, depending on their source and on the temperature and duration of their storage. a total of 375 table eggs were studied, from a large-scale poultry farm, a small-scale poultry farm and a supermarket. each group was divided into 5 subgroups according to the te ... | 2010 | 21033566 |
| bacterial species associated with sound and botrytis-infected grapes from a greek vineyard. | grape bacterial microbiota plays central roles in the quality of grapes and wine, yet its diversity remains poorly described. in the present study, bacterial species associated with sound and botrytis-infected grapes of two cultivars originating from the same vineyard were assessed. isolates were identified by pcr-denaturing gradient gel electrophoresis (pcr-dgge) and sequence analysis of partial 16s rrna gene. comparable counts were recorded between botrytis-infected and sound grape samples. in ... | 2011 | 21315469 |
| tatumella saanichensis sp. nov., isolated from a cystic fibrosis patient. | polyphasic taxonomic analysis was performed on a clinical isolate (nml 06-3099t) from a cystic fibrosis patient, including whole-genome sequencing, proteomics, phenotypic testing, electron microscopy, chemotaxonomy and a clinical investigation. comparative whole-genome sequence analysis and multilocus sequence analysis (mlsa) between tatumella ptyseos atcc 33301t and clinical isolate nml 06-3099t suggested that the clinical isolate was closely related to, but distinct from, the species t. ptyseo ... | 2015 | 25807976 |
| isolation, identification and antimicrobial susceptibility pattern of tatumella ptyseos strains isolated from powdered infant formula milk consumed in neonatal intensive care unit: first report from iran. | tatumella ptyseos is a rod-shaped, gram-negative, facultative, and anaerobic bacteria categorized in the enterobacteriaceae family. it is a rare food-borne opportunistic pathogen which causes neonatal sepsis, bacteremia, and urinary tract infections. t. ptyseos has been also cultured from various food sources around the world. | 2014 | 25371802 |
| biodiversity, dynamics and ecology of bacterial community during grape marc storage for the production of grappa. | the italian spirit obtained from grape marc, grappa, is produced by an extended storage of the marc which allows alcoholic fermentation. bacterial populations can develop and are associated with off-flavour production. grape marc acidification before storage is a common practice in distilleries to control bacterial proliferation. few studies have been published on the microbial biodiversity in grape marc and no information exists about microbiology of acidified marcs and physiological properties ... | 2013 | 23416549 |
| spontaneous organic cocoa bean box fermentations in brazil are characterized by a restricted species diversity of lactic acid bacteria and acetic acid bacteria. | spontaneous organic cocoa bean box fermentations were carried out on two different farms in brazil. physical parameters, microbial growth, bacterial species diversity [mainly lactic acid bacteria (lab) and acetic acid bacteria (aab)], and metabolite kinetics were monitored, and chocolates were produced from the fermented dry cocoa beans. the main end-products of the catabolism of the pulp substrates (glucose, fructose, and citric acid) by yeasts, lab, and aab were ethanol, lactic acid, mannitol, ... | 2011 | 21839382 |
| transfer of pantoea citrea, pantoea punctata and pantoea terrea to the genus tatumella emend. as tatumella citrea comb. nov., tatumella punctata comb. nov. and tatumella terrea comb. nov. and description of tatumella morbirosei sp. nov. | pantoea citrea, pantoea punctata and pantoea terrea were described for strains isolated from fruit and soil originating in japan. these three 'japanese' species have been shown to be phylogenetically distant from other species of the genus pantoea. it has been observed previously that, using multilocus sequence analysis (mlsa), the 'japanese' species consistently formed a distinct clade with an extended branch length, casting doubt on the inclusion of these species within the genus pantoea. furt ... | 2010 | 19654354 |
| tatumella ptyseos causing severe human infection: report of the first two brazilian cases. | tatumella ptyseos is the type species of the tatumella genus (enterobacteriaceae). this fermentative gram-negative rod has only rarely been reported as a cause of human infections; there is very little information about it in the medical literature. we report here the first two brazilian cases of t. ptyseos infections, both evolving to severe sepsis. | 2008 | 19219286 |
| unusual stability of manganese superoxide dismutase from a new species, tatumella ptyseos ct: its gene structure, expression, and enzyme properties. | a genomic dna of 1416 bp containing an open reading frame encoding a manganese superoxide dismutase (mn-sod) from tatumella ptyseos ct was cloned. sequence analysis of this new gene revealed that it translates 205 amino acid residues. the deduced amino acid sequence showed variable identities (41-91%) with sequences of mn-sods from other species. the residues required to coordinate the single trivalent manganese ion and the 11 residues putatively involved in the active center are conserved as th ... | 2005 | 15721770 |
| tatumella ptyseos gen. nov., sp. nov., a member of the family enterobacteriaceae found in clinical specimens. | the name tatumella ptyseos gen. nov., sp. nov., is proposed for a group of organisms (previously called group ef-9) isolated from clinical sources in the united states, canada, and puerto rico. a total of 68% of these isolates were from sputum specimens. t. ptyseos strains are gram-negative, oxidase-negative, fermentative rods that grow on macconkey agar. the distinctive biochemical characteristics of 44 t. ptyseos isolates were as follows: acid but no gas from d-glucose, sucrose, and, usually ( ... | 1981 | 7263854 |
| the first isolate of tatumella ptyseos in malaysia. | tatumella ptyseos, the type species for the genus tatumella, is a newly established member of the family enterobacteriaceae. it is a gram-negative, oxidase negative, fermentative rod that grows on mac conkey agar. this first isolate was obtained from the blood culture of a neonate having neonatal jaundice with presumed sepsis. the organism was in vitro sensitive to gentamicin, chloramphenicol, cotrimoxazole and ampicillin. the patient was treated with ampicillin and gentamicin and recovered unev ... | 1989 | 2632996 |
