Aeromonas strains which phenotypically and genetically belong to the salmonicida species but that according their phenotypic properties constitute a new subspecies have been isolated from water of heavily polluted river, Matanza situated near central district Buenos Aires city. These were ascribed A. by using 65 biochemical tests DNA-DNA hybridization. They produce acid -sorbitol, an unusual property found in few members species. also utilize urocanic do not ferment L-rhamnose or LD-lactate,...
The genus Coprothermobacter (initially named Thermobacteroides) is currently placed within the phylum Firmicutes. Early 16S rRNA gene based phylogenetic studies pointed out great differences between and other members of Firmicutes, revealing that it constitutes a new deep branching lineage. Over years, several on whole genome sequences have indicated very distant phylogenetically to all bacteria, supporting its placement in distinct deeply rooted novel phylum. In view this, we propose...
A new anaerobic, proteolytic, moderately thermophilic bacterium, strain 3RT, was isolated from a methanogenic mesophilic reactor treating protein-rich wastewater. The cells were Gram-negative, non-spore-forming, non-motile rods. DNA base composition 43 mol% G+C. optimum pH and temperature for growth 7·0 55 °C respectively. bacterium fermented gelatin, casein, bovine albumin, peptone yeast extract. Glucose, fructose, sucrose, maltose starch poorly fermented. major fermentation products...
In order to assess the relationship between genus Kluyvera and other members of family Enterobacteriaceae, 16S rRNA genes type strains recognized species, georgiana, cochleae, ascorbata cryocrescens, were sequenced. A comparative phylogenetic analysis based on these gene sequences those available for belonging several genera Enterobacteriaceae showed that form a cluster contains all known species. However, strain Enterobacter intermedius (ATCC 33110T) was included within this in very close...
Abstract Background Guanine crystals are organic biogenic found in many organisms. Due to their exceptionally high refractive index, they contribute structural color and responsible for the reflective effect skin visual organs animals such as fish, reptiles, spiders. Occurrence of these has been known years, have also observed eukaryotic microorganisms, but not prokaryotes. Results In this work, we report discovery extracellular formed by bacteria reveal that composed guanine monohydrate....
Leptospirosis is the most widespread zoonosis in world and significant efforts have been made to determine classify pathogenic Leptospira strains. This maintained nature through chronic renal infections of carrier animals, with rodents other small mammals serving as important reservoirs. Additionally, domestic such livestock dogs, are sources human infection. In this study, a multiple-locus variable-number tandem repeat analysis (MLVA) was applied genotype 22 strains isolated from urban...
ABSTRACT Aeromonas salmonicida subsp. pectinolytica 34mel T can be considered an extremophile due to the characteristics of heavily polluted river from which it was isolated. While four subspecies A. are known fish pathogens, belongs only isolated solely environment. Genome analysis revealed a high metabolic versatility, capability cope with diverse stress agents, and lack several virulence factors found in pathogenic . The most relevant phenotypic pectin degradation, distinctive trait ,...
The genome of Aeromonas salmonicida subsp. pectinolytica strain 34mel(T), isolated from a heavily polluted river, contains several genomic islands and putative virulence genes. identification genes involved in resistance to different kinds stress sheds light on the mechanisms used by this thrive an extreme environment.
Bacillus anthracis protective antigen (PA) is a well known and relevant immunogenic protein that the basis for both anthrax vaccines diagnostic methods. Properly folded antigenic PA necessary these applications. In this study high level of was obtained in recombinant Escherichia coli. The initially accumulated inclusion bodies, which facilitated its efficient purification by simple washing steps; however, it could not be recognized specific antibodies. Refolding conditions were subsequently...
The moss flora of the Fuegian region is fairly well-known and unexplored areas are relatively few. compilation all records scattered over more than two centuries exploration studies in Tierra del Fuego Malvinas Islands resulted recognition 369 species, 3 subspecies 29 varieties distributed 119 genera. A few taxa newly recorded for are: Fallaciella Crum, Campylopus subnitens Kaal., Dicranoweisia mackayi (Broth. & Dix.) Broth., Didymodon andreaeoides Card. gracilis Philonotis polymorpha...
