| [appendicitis: microbial interactions and new pathogens]. | the authors present an exhaustive review on microbial agents of appendicitis by means of literature and personal research data. thus, a detailed analysis is made on common autochthonous agents and their pathogenetic interactions and on less common exogenous bacterial, viral, mycotic, protozoan and helminthic agents with emphasis to the role of yersinia enterocolitica. in fact this bacterium seems responsible for 3% to 8% of cases in accordance with literature and personal research data (more det ... | 1992 | 1323137 |
| susceptibilities to antibiotics and antiseptics of new species of the family enterobacteriaceae. | one hundred and sixty-nine strains of new species of the family enterobacteriaceae, isolated mainly from the environment, were tested to determine their susceptibilities to 13 antibiotics and 4 antiseptics or disinfectants. all the species were susceptible to aminoglycosides, doxycycline, and trimethoprim but were resistant to chloramphenicol. susceptibility to beta-lactams varied more among the strains. however, all the strains were cefotaxime susceptible, apart from some buttiauxella agrestis ... | 1988 | 3415208 |
| isolation and properties of free and immobilized beta-galactosidase from the psychorotrophic enterobacterium buttiauxella agrestis (strain nc4). | a study of the beta-galactosidase produced by the psychrotrophic bacterium buttiauxella agrestis has been carried out. this micro-organism was isolated from raw milk and the enzyme isolated using standard methods. molecular mass was estimated to be 515 kda. the isoelectric point was close to 4.45. optimum ph was 7.25. maximal activity was observed at 50 degrees c and activation energy was estimated to be 39.1 kj mol-1. lactose enhanced thermal stability. using p-nitrophenyl-beta-d-galactopyranos ... | 1995 | 7615419 |
| the reduction of nitrous oxide to dinitrogen by escherichia coli. | escherichia coli k12 reduces nitrous oxide stoichiometrically to molecular nitrogen with rates of 1.9 mumol/h x mg protein. the activity is induced by anaerobiosis and nitrate. n2-formation from n2o is inhibited by c2h2 (ki approximately 0.03 mm in the medium) and nitrite (ki = 0.3 mm) but not by azide. a mutant defective in fnr synthesis is unable to reduce n2o to n2. the reaction in the wild type could routinely be followed by gas chromatography and alternatively by mass spectrometry measuring ... | 1993 | 8297209 |
| emended description of buttiauxella agrestis with recognition of six new species of buttiauxella and two new species of kluyvera: buttiauxella ferragutiae sp. nov., buttiauxella gaviniae sp. nov., buttiauxella brennerae sp. nov., buttiauxella izardii sp. nov., buttiauxella noackiae sp. nov., buttiauxella warmboldiae sp. nov., kluyvera cochleae sp. nov., and kluyvera georgiana sp. nov. | a total of 219 strains belonging to the genera buttiauxella and kluyvera were studied; 171 of these strains were isolated from mollusks, mainly snails and slugs, obtained from around the world. on the basis of dna-dna hybridization data, the strains were grouped into 11 genomospecies. a total of 44 phenotypic characters were used to differentiate the genera buttiauxella and kluyvera at the genus level and to identify genomospecies. there were significantly higher phenotypic probability distances ... | 1996 | 11534554 |
| inducible ampc beta-lactamase of a new member enterobacteriaceae. | extensive biochemical testing and 16s rrna and rpob sequence analysis revealed that clinical strain cf01ent1, initially identified as buttiauxella agrestis by the use of api 32 biochemical strips, is a new organism in the enterobacteriaceae family. it produced an inducible ampc-type beta-lactamase whose sequence shares 69 to 72% identity with those of the other ampc-type beta-lactamases of enterobacteriaceae: this enzyme exhibits an atypical high affinity for all beta-lactams tested. | 2002 | 12234870 |
| insights into antimicrobial resistance among long distance migratory east canadian high arctic light-bellied brent geese (branta bernicla hrota). | antimicrobial resistance (amr) is the most significant threat to global public health and ascertaining the role wild birds play in the epidemiology of resistance is critically important. this study investigated the prevalence of amr gram-negative bacteria among long-distance migratory east canadian high arctic (echa) light-bellied brent geese found wintering on the east coast of ireland. | 2015 | 27651892 |
| draft genome sequence of buttiauxella agrestis, isolated from surface water. | mi agar is routinely used for quantifying escherichia coli in drinking water. a suspect e. coli colony isolated from a water sample was identified as buttiauxella agrestis. the whole genome sequence of b. agrestis was determined to understand the genetic basis for its phenotypic resemblance to e. coli on mi agar. | 2014 | 25323724 |
| post-cesarean surgical site infection due to buttiauxella agrestis. | surgical site infections (ssi) are postoperative complications that constitute a major public health problem. we present a rare case report of infection by buttiauxella agrestis, a member of the enterobacteriaceae family, occurring after a cesarean delivery in a young woman with no comorbidities. the authors further discuss the origin of this infection. | 2014 | 24641982 |
| interaction of bacterial membrane vesicles with specific species and their potential for delivery to target cells. | membrane vesicles (mvs) are secreted from a wide range of microbial species and transfer their content to other cells. although mvs play critical roles in bacterial communication, whether mvs selectively interact with bacterial cells in microbial communities is unclear. in this study, we investigated the specificity of the mv-cell interactions and evaluated the potential of mvs to target bacterial cells for delivery. mv association with bacterial cells was examined using a fluorescent membrane d ... | 2017 | 28439261 |
