Résumé :

The standardized nomenclature of rodent strains, genes and mutations has long been the focus of careful attention. Its aim is to provide proper designation of laboratory animals used in research projects and to convey as much information on each strain as possible. Since the development of different techniques to mutate the genome of laboratory rodents on a large scale, the correct application of current nomenclature systems is of increased significance. It facilitates not only the accurate communication of scientific results but is indispensable in controlling the dramatically increased numbe

Strains now considered to represent the type strain of Arthrobacter ilicis, described as a pathogen of American holly, are not identical. The designated type strain does not represent this pathogen.

It is proposed that A. ilicis is an unrelated species, not a pathogen of American holly.

The diversity of green microalgae in subaerial habitats remains largely unexplored and a number of new genus- and species-level lineages have been discovered recently.

In this study, we provide a detailed characterization of two strains of microalgae isolated from tree bark in the Mediterranean.

Résumé :

ABSTRACTHybrid isolates of Shiga toxin-producingEscherichia coli(STEC) and enterotoxigenicE. coli(ETEC) encoding heat-stable enterotoxin (ST) are being reported with increasing frequency from a variety of sources. However, information regarding the plasmids that these strains harbor is scarce. In this study, we sequence and characterize a plasmid, p7v, from the STEC/ETEC hybrid strain 7v. Whole-genome phylogenetic analyses of STEC/ETEC hybrid strains and prototypeE. coliisolates of other pathotypes placed 7v in theEscherichiasp. cryptic lineage 1 (CL1) clade. The complete plasmid, p7v, was det

Résumé :

During a study of biodiversity of cyanobacteria in Gorely volcano soils (Kamchatka Peninsula), a strain of heterocytous, a false branching cyanobacterium with gradually tapered filaments, was isolated. Prominent features of the strain were purplish-grey trichomes and firm, distinct multilayered sheaths. Based on the results obtained from the morphological, ecological, and phylogenetic analysis using the 16S rRNA and 16S–23S ITS region, 16S–23S ITS secondary structure analysis, comparison of flanking regions of BoxB and V3 helices, and the p-distance between the 16S–23S ITS region, we describe

Extending our knowledge on human skin microbiota is a challenge to better decipher its role in health and disease. Using the culturomics method, we isolated strain Marseille-Q4368 from the healthy forehead of a 59-year-old woman. We describe here the main characteristics of this bacterium using a taxonogenomic approach. This new bacterial species is Gram-positive, non-motile, and non-spore-forming. Its 16S rRNA sequence exhibited a similarity of 99.59% with Leucobacter chromiiresistens, the most closely related species in terms of nomenclature. However, a digital DNA–DNA hybridization analysis

Résumé :

Peridinium acuminatum (Peridiniales, Dinophyceae) was described in the first half of the 19th century, but the name has been rarely adopted since then. It was used as type of Goniodoma, Heteraulacus and Yesevius, providing various sources of nomenclatural and taxonomic confusion. Particularly, several early authors emphasised that the organisms investigated by C.G. Ehrenberg and S.F.N.R. von Stein were not conspecific, but did not perform the necessary taxonomic conclusions. The holotype of P. acuminatum is an illustration dating back to 1834, which makes the determination of the species ambig

Résumé :

The predominant clonal evolution (PCE) model is often misunderstood. Contrary to common belief, it is not restricted to strict mitotic clonality. Instead, it encompasses processes such as selfing, strong homogamy, and various forms of parthenogenesis, as widely acknowledged by researchers studying clonality. Moreover, the PCE model does not claim that genetic recombination is entirely absent or devoid of epidemiological and evolutionary significance. In this review, I will explore the reciprocal relationship between PCE and molecular epidemiology (strain typing) and discuss the implications of

ABSTRACT Hepatitis C virus (HCV) evolution is thought to proceed by mutations within the six genotypes. Here, we report on a viable spontaneous HCV recombinant and we show that recombination may play a role in the evolution of this virus. Previously, 149 HCV strains from St. Petersburg had been subtyped by limited sequencing within the NS5B region. In the present study, the core regions of 41 of these strains were sequenced to investigate the concordance of HCV genotyping for these two genomic regions. Two phylogenetically related HCV strains were found to belong to different subtypes, 2k and

Résumé :

Enteroviruses (EV) have traditionally been identified by using serotype-specific antisera in a virus-neutralization test. Three EV strains isolated in California, USA, in 1955, 1964 and 1978, and a 1995 Oman isolate, were found to be antigenically related to one another; however, the strains were not neutralized by standard EV typing antisera, suggesting that they may represent a new EV serotype. The isolates were characterized genetically by RT–PCR coupled with amplicon sequencing and comparison to a database of enterovirus nucleotide sequences. The strains were 75·3 to 87·2% identical to one

Résumé :

Members of the order Halobacteriales are obligate extreme halophiles that belong to the domain Archaea. The classification of the Halobacteriales currently relies on a polyphasic approach, which integrates phenotypic, genotypic and chemotaxonomic characterization. However, the most utilized genetic marker for phylogeny, the 16S rRNA gene, has multiple drawbacks for use with the Halobacteriales: the species of many genera exhibit large intragenic differences between multiple ribosomal RNA operons, the gene is too conserved to discriminate reliably at the species level and it appears to be the m

ABSTRACT This report provides in vivo evidence for the posttranslational control of the acetyl coenzyme A (Ac-CoA) synthetase (AcsA) enzyme of Bacillus subtilis by the acuA and acuC gene products. In addition, both in vivo and in vitro data presented support the conclusion that the yhdZ gene of B. subtilis encodes a NAD+-dependent protein deacetylase homologous to the yeast Sir2 protein (also known as sirtuin). On the basis of this new information, a change in gene nomenclature, from yhdZ to srtN (for sirtuin), is proposed to reflect the activity associated with the YdhZ protein. In vivo contr

The lack of a convenient high-resolution strain-typing method has hampered the application of molecular epidemiology to the surveillance of bacteria of the Mycobacterium tuberculosis complex, particularly the monitoring of strains of Mycobacterium bovis. With the recent availability of genome sequences for strains of the M. tuberculosis complex, novel PCR-based M. tuberculosis-typing methods have been developed, which target the variable-number tandem repeats (VNTRs) of minisatellite-like mycobacterial interspersed repetitive units (MIRUs), or exact tandem repeats (ETRs).

Over the last few decades, several pestiviruses have been discovered in ruminants, pigs, and, more recently, in non-ungulate hosts.

In this study, during a survey of pestivirus infections in ovine farms in the Lombardy region of Northern Italy, we identified and isolated a pestivirus strain from a sheep that was found to belong to Pestivirus N species based on it

Mutant PHB11 also showed an inhibition of photosynthesis that was much more pronounced at alkaline pH. Reconstruction of the transposon mutation of PHB11 in the wild-type strain reproduced the phenotype of the original mutant. The wild-type version of the mutated gene was cloned and the mutation complemented. In mutant strain PHB11, the transposon had in
