| the avian haemophili. | there are four currently recognized taxa to accommodate the avian haemophili: haemophilus paragallinarum, pasteurella avium, pasteurella volantium, and pasteurella species a (the last three being formerly united as haemophilus avium). a range of other taxa has also been recognized, but they have been neither named nor assigned to a genus. all of these various taxa, legitimate and otherwise, have the common characteristic of requiring v factor, but not x factor, for in vitro growth. several recen ... | 1989 | 2670190 |
| differential distribution of novel restriction-modification systems in clonal lineages of neisseria meningitidis. | using representational difference analysis, we isolated novel meningococcal restriction-modification (r-m) systems. nmebi, which is a homologue of the r-m system hgai of pasteurella volantium, was present in meningococci of the et-5 complex and of lineage iii. nmeai was found in serogroup a, et-37 complex, and cluster a4 meningococci. nmedi was harbored by meningococci of the et-37 complex and of cluster a4, but not by serogroup a meningococci. two of the r-m systems, nmebi and nmedi, were locat ... | 2000 | 10671450 |
| genomic fingerprints, ardra profiles and quinone systems for classification of pasteurella sensu stricto. | in order to investigate the relationships between species of the genus pasteurella sensu stricto such as pasteurella multocida, pasteurella canis, pasteurella stomatis, pasteurella dagmatis, pasteurella avium, pasteurella volantium, pasteurella gallinarum, pasteurella species a, pasteurella species b and "pasteurella leonis" mccm 00659 their genomic fingerprints and ardra profiles were compared and their quinone systems were analysed. visual comparison of band patterns from rep-pcr (eric-, rep- ... | 2000 | 11249019 |
| genotypic heterogeneity of pasteurella gallinarum as shown by ribotyping and 16s rrna sequencing. | forty-five strains mainly isolated from chickens in zimbabwe and denmark, two pig and three rat isolates all identified as pasteurella gallinarum by conventional phenotypic tests were characterized by ribotyping, and selected strains were subsequently analysed by 16s rrna gene sequencing. high genotypic diversity was observed, the number of ribotypes totalling 24. a major group of 47 isolates including the type strain of p. gallinarum clustered at 56% similarity and included 21 ribotypes. riboty ... | 2002 | 12593745 |
| genetic analysis of a plasmid encoding haemocin production in haemophilus paragallinarum. | the full sequence of plasmid p250, isolated from haemophilus paragallinarum strain hp250, has been obtained. the plasmid contains seven orfs: a putative integrase, a putative replication protein (repb) and five orfs similar to those from the haemocin (bacteriocin) hmcdcbai operon from haemophilus influenzae. of 19 other non-plasmid-containing h. paragallinarum strains screened (11 serovar reference strains and 8 field isolates), 17 strains produced haemocin and were resistant to killing by strai ... | 2003 | 14600229 |
| reclassification of pasteurella gallinarum, [haemophilus] paragallinarum, pasteurella avium and pasteurella volantium as avibacterium gallinarum gen. nov., comb. nov., avibacterium paragallinarum comb. nov., avibacterium avium comb. nov. and avibacterium volantium comb. nov. | this paper describes a phenotypic and genotypic investigation of the taxonomy of [haemophilus] paragallinarum, pasteurella gallinarum, pasteurella avium and pasteurella volantium, a major subcluster within the avian 16s rrna cluster 18 of the family pasteurellaceae. an extended phenotypic characterization was performed of the type strain of [haemophilus] paragallinarum, which is nad-dependent, and eight nad-independent strains of [haemophilus] paragallinarum. complete 16s rrna gene sequences wer ... | 2005 | 15653900 |
| taxonomy of some recently described avian pasteurella/actinobacillus-like organisms as indicated by deoxyribonucleic acid relatedness. | members of the family pasteurellaceae pohl 1981 are frequently encountered in birds as parasites or pathogens, e.g. the well-known species pasteurella multocida, pasteurella gallinarum, haemophilus paragallinarum, and three species containing strains that had been previously classified as "haemophilus avium"(pasteurella avium, pasteurella volantium, and an unnamed pasteurella species defined by mutters et al., 1985). a variety of additional taxa which had been tentatively assigned to the family ... | 1985 | 18766923 |
| phylogenetic relationships of unclassified, satellitic pasteurellaceae obtained from different species of birds as demonstrated by 16s rrna gene sequence comparison. | avian haemophili demonstrating in vitro satellitic growth, also referred to as the v-factor or nad requirement, have mainly been classified with avibacterium paragallinarum (haemophilus paragallinarum), avibacterium avium (pasteurella avium), avibacterium volantium (pasteurella volantium) and avibacterium sp. a (pasteurella species a). the aim of the present study was to assess the taxonomic position of 18 v-factor-requiring isolates of unclassified haemophilus-like organisms isolated from galli ... | 2009 | 19573597 |
| multilocus sequence phylogenetic analysis of avibacterium. | this study examined 49 field isolates of the genus avibacterium, with these 49 being allocated to 36 epidemiologically unrelated groups with one isolate from each group being examined in detail. in addition, six type and reference strains were investigated. phylogenetic analysis of partially sequenced recn, rpob, infb, pgi and soda genes confirmed the existence of the species avibacterium paragallinarum, while a species complex encompassing avibacterium volantium, avibacterium avium, avibacteriu ... | 2012 | 22241047 |
| the lateral angiogram in the differentiation of extracerebral hematomas. | the pathophysiology of epidural hematomas is considerably different from that of subdural hematomas. epidural hematomas are well-localized intracranial masses under high pressure, whereas subdural hematomas are more widespread collections of blood under lower pressure. the underlying small cortical vessels are normal in both acute and chronic subdural hematomas but are severely distorted in epidural hematomas. the appearance of these vessels, seen best in the lateral projection, can help differe ... | 2005 | 1153776 |
| maldi-tof mass spectrometry confirms difficulties in separating species of the avibacterium genus. | in the present study a well-characterized strain collection (n = 33) of avibacterium species was investigated by matrix-assisted laser desorption ionization-time-of flight mass spectrometry (maldi-tof ms). the robustness of the currently available reference database (bruker biotyper 3.0) was tested to determine the degree of identification of these strains. reproducible signal patterns were obtained from all strains. however, identification of most strains was only possible at genus level. furth ... | 2014 | 24802229 |
