Thalassobacter stenotrophicus gen. nov., sp. nov., a novel marine alpha-proteobacterium isolated from Mediterranean sea water.
2005
A Gram-negative, slightly halophilic, strictly aerobic, chemo-organotrophic bacterium was isolated from Mediterranean sea water near Valencia (Spain). 16S rRNA gene sequence comparisons showed that the isolate represented a separate branch within the α-3 subclass of the Proteobacteria, now included within the order ‘Rhodobacterales’. Jannaschia helgolandensis was the closest relative, but their low sequence similarity and other features indicated that they were not related at the genus level. Isolate 5SM22T produced bacteriochlorophyll a and grew on solid media as regular salmon-pink colonies. Cells are motile rods, with polar flagella. The DNA G+C content is 59·1 mol%. Morphological, physi…
Canibacter oris gen. nov., sp. nov., isolated from an infected human wound.
2014
A facultatively anaerobic, Gram-reaction-positive, catalase- and oxidase-negative, rod-shaped bacterium isolated from an infected human wound caused by a dog bite was characterized by phenotypic and molecular genetic methods. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IMMIB Q2029717T was a member of the order Micrococcales of the class Actinobacteria , displaying 91.6 % to 96 % sequence similarity with members of the family Microbacteriaceae . Phylogentic trees generated by different algorithms indicated that the strain forms an independent phylogenetic line of descent that consistently clustered proximal to the base of the genus Leucobacter . Chemical studies…
Sphingomonas fennica sp. nov. and Sphingomonas haloaromaticamans sp. nov., outliers of the genus Sphingomonas.
2007
Bacterial isolates obtained from polychlorophenol-contaminated sites in Finland (strain K101T) and from a Dutch drinking water well (strain A175T) were characterized taxonomically. 16S rRNA gene sequence analysis, determination of DNA G+C content, physiological characterization, estimation of the ubiquinone and polar lipid patterns and fatty acid content revealed that strains K101T and A175T were similar to Sphingomonas wittichii RW1T but also showed pronounced differences. The DNA G+C contents of the two novel strains were 63.6 and 66.1 mol%, respectively. On the basis of these results, two novel species of the genus Sphingomonas are described, for which the names Sphingomonas haloaromatic…
Description of Tropicibacter mediterraneus sp. nov. and Tropicibacter litoreus sp. nov.
2013
Four strains (M15∅_3, M17(T), M49 and R37(T)) were isolated from Mediterranean seawater at Malvarrosa beach, Valencia, Spain. Together with an older preserved isolate (strain 2OM6) from cultured oysters at Vinaroz, Castellón, Spain, the strains were thoroughly characterized in a polyphasic study and were placed phylogenetically within the Roseobacter clade in the family Rhodobacteraceae. Highest 16S rRNA sequence similarities of the five strains to the types of any established species corresponded to Tropicibacter multivorans (95.8-96.4%), Phaeobacter inhibens (95.9-96.3%) and Phaeobacter gallaeciensis (95.9-96.2%). On the other hand, whole genome (ANI) and protein fingerprinting (MALDI-TOF…
Phylogenetic analysis of the genera Proteus, Morganella and Providencia by comparison of rpoB sequences of type and clinical strains suggests the cla…
2010
Phylogenetic analysis of partial rpoB gene sequences of type and clinical strains belonging to different 16S rRNA gene-fingerprinting ribogroups within 11 species of enterobacteria of the genera Proteus, Morganella and Providencia was performed and allowed the definition of rpoB clades, supported by high bootstrap values and confirmed by ≥2.5 % nucleotide divergence. None of the resulting clades included strains belonging to different species and the majority of the species were confirmed as discrete and homogeneous. However, more than one distinct rpoB clade could be defined among strains belonging to the species Proteus vulgaris (two clades), Providencia alcalifaciens (two clades) and Pro…
Simultaneous detection of Carnobacterium and Leuconostoc in meat products by multiplex PCR.
2004
M.C. MACIAN, E. CHENOLL AND R. AZNAR. 2004. Aims: To develop a multiplex PCR approach for simultaneous detection of Leuconostoc and Carnobacterium and its validation in meat products. Methods and Results: Two multiplex PCR assays were developed using newly designed 16S rDNA-directed primers adapted to the current taxonomic situation of genera Leuconostoc and Carnobacterium that allow: (i) simultaneous detection of both genera, and members of the nonmotile species of genus Carnobacterium and (ii) identification in a single assay of the nonmotile species C. divergens, C. maltaromicum and C. gallinarum. Sensitivity values of 10 3 and 10 4 CFU g )1 were determined for multiplex PCR detection of…
Pseudomonas lini sp. nov., a novel species from bulk and rhizospheric soils.
2002
The taxonomic position of eight fluorescent Pseudomonas strains isolated from bulk and rhizospheric soils, and from water was examined. These eight strains clustered in one phenon together with Pseudomomas mandelii (CFBP 4844T), but could still be differentiated from this type strain by four phenotypic features. The eight stains exhibited internal DNA-DNA hybridization values ranging from 60 to 100%, with deltaTm below 5 degrees C (3.9 and 4.3 degrees C) for the lowest values (60 and 66%). The percentages of hybridization with type or reference strains of other Pseudomonas species tested ranged from 12 to 60% (deltaTm = 5.5 degrees C), indicating that the eight isolates studied constituted …
A new species ofHalocnemumM.Bieb. (Amaranthaceae) from southern Turkey
2008
Halocnemum yurdakulolii Yaprak is described as the second species of the previously monotypic genus Halocnemum. The species is endemic to the Goksu Delta in southern Turkey. The main morphological characteristics that separate H. yurdakulolii from H. strobilaceum (Pall.) M.Bieb. are growth form and spike morphology. Apart from these morphological differences, the species show a clear genetic differentiation. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 716–721.
Description of the unknown fifth instar of Emblethis duplicatus Seidenstücker, 1963 (Hemiptera: Heteroptera: Rhyparochromidae), with a key to 5th ins…
2011
Currently, the Palaearctic genus Emblethis Fieber, 1860 comprises 29 species (Pericart 2001). Up to date, the 5 th instars were known only for five species representing this genus, i.e., E . ciliatus Horvath, E . verbasci (Fabricius), E . griseus (Wolff), E . denticollis Horvath, and E . minutus Kiritshenko— descriptions and keys for their identification were provided by Putshkov (1969), and Pericart (1999).
Short report - A new case report of human Mesocestoides infection in the United States
2003
The twenty-seventh documented case of human Mesocestoides infection, which corresponds to the seventh documented case in the United States, is reported. The case had its origin in Alexandria, Louisiana in the summer of 1998. The patient was a 19-month-old boy. The strobila consisted of 35 proglottids that included mature as well as gravid segments containing a ventral genital pore and a parauterine organ. After a detailed microscopic examination, the tapeworm was identified as belonging to the genus Mesocestoides. Mesocestoides variabilis is the probable species responsible for the infection, since the six cases previously reported in the United States were identified as this species. After…
