In this article, we have reviewed the work carried out by the UFRJ microbiology laboratory related towater quality and microorganisms associated with different aquatic ecosystems. We placed water at the center oftheOneHealthconcept,duetotheintegrationthatwatermakesbetweendifferentlivingbeingsandtheenvironment.We selected papers published between 20...
Pseudomonas aeruginosa is a ubiquitous microorganism, capable of colonizing a wide range of habitats due to its metabolic versatility and wide adaptability to different conditions. Industrial and environmental research involving petroleum microbiology play a pivotal role in controlling many technical, operational, and environmental issues. P. aerug...
Pseudomonas aeruginosa is an opportunistic pathogen and an important model organism for the study of bacterial group behaviors, including cell motility and biofilm formation. Rhamnolipids play a pivotal role in biofilm formation and motility phenotypes in P. aeruginosa, possibly acting as wetting agents and mediating chemotactic stimuli. However, n...
Petroleum microbiology is important to the fossil oil industry and any related environmental research. Assessment of resident microbial communities is essential for controlling many technical, operational, and environmental issues. However, difficulties of sampling and extraction are limiting factors. Herein, we assessed the bacterial and archaeal...
Background: Pseudomonas aeruginosa is an opportunistic pathogen and an important model organism for the study of bacterial group behaviors, including cell motility and biofilm formation. Rhamnolipids play a pivotal role on biofilm formation and motility phenotypes in P. aeruginosa, possibly acting as wetting agents and mediating chemotactic stimuli...
Burkholderia harbors versatile Gram‐negative species and is β‐Proteobacteria. Recently, it was proposed to split the genus in two main branches: one of animal and plant pathogens and another, Paraburkholderia, harboring environmental and plant‐beneficial species. Currently, Paraburkholderia comprises more than 70 species with ability to occupy very...
Two Gram-negative, motile, aerobic bacteria isolated from waters of the Abrolhos Bank were classified through a whole genome-based taxonomy. Strains PEL67ET and PEL68C shared 99% 16S rRNA and dnaK sequence identity with Alteromonas marina SW-47T and Alteromonas macleodii ATCC 27126T. In silico DNA–DNA Hybridization, i.e. genome-to-genome distance (...
The Brown Ring Disease (BRD) caused high mortality rates since 1986 in the Manila clam Venerupis philippinarum introduced and cultured in Western Europe from the 1970s. The causative agent of BRD is a Gram-Negative bacterium, Vibrio tapetis, which is also pathogenic to fish. Here we report the first assembly of the complete genome of V. tapetis CEC...
We present here the draft genome sequence of Pseudoalteromonas sp. strain PAB 2.2, isolated from water of Parcel de Abrolhos coral reef (17°57′32.7″; 38°30′20.3″), on Abrolhos Bank, at a depth of 12 m. The assembly consists of 4,434,635 bp and contains 40 contigs, with a G+C content of 41.60%.
Background
Salinivibrios are moderately halophilic bacteria found in salted meats, brines and hypersaline environments. We obtained three novel conspecific Salinivibrio strains closely related to S. costicola, from Socompa Lake, a high altitude hypersaline Andean lake (approx. 3,570 meters above the sea level).
Results
The three novel Salinivibrio...
Three novel isolates (A-354T, A-328, and A-384) were retrieved from apparently healthy scleractinian Madracis decactis in the remote St Peter & St Paul Archipelago, Mid-Atlantic Ridge, Brazil. The novel isolates formed a distinct lineage based on the phylogenetic reconstruction using the 16S rRNA and pyrH gene sequences. They fell into the Mediterr...
Vibrios are ubiquitous in the aquatic environment and can be found in association with animal or plant hosts. The range of ecological relationships includes pathogenic and mutualistic associations. To gain a better understanding of the ecology of these microbes, it is important to determine their phenotypic features. However, the traditional phenot...
We report on the genome sequences of Lactobacillus vini type strain LMG 23202T (DSM 20605) (isolated from fermenting grape musts in Spain) and the industrial strain L. vini JP7.8.9 (isolated from a bioethanol plant in northeast Brazil). All contigs were assembled using gsAssembler, and genes were
predicted and annotated using Rapid Annotation using...
Vibrio campbellii PEL22A was isolated from open ocean water in the Abrolhos Bank. The genome of PEL22A consists of 6,788,038 bp (the GC content
is 45%). The number of coding sequences (CDS) is 6,359, as determined according to the Rapid Annotation using Subsystem Technology
(RAST) server. The number of ribosomal genes is 80, of which 68 are tRNAs a...
Vibrio sp. strain DS40M4 is a marine bacterium that was isolated from open ocean water. In this work, using genomic taxonomy, we
were able to classify this bacterium as V. campbellii. Our genomic analysis revealed that V. campbellii DS40M4 harbors genes related to iron transport, virulence, and environmental fitness, such as those encoding anguibac...
Vibrio cholerae O1 Amazonia is a pathogen that was isolated from cholera-like diarrhea cases in at least two countries, Brazil and Ghana.
Based on multilocus sequence analysis, this lineage belongs to a distinct profile compared to strains from El Tor and classical
biotypes. The genomic analysis revealed that it contains Vibrio pathogenicity island...
We dissected the complete genome sequence of the O1 serotype strain Vibrio anguillarum 775(pJM1) and determined the draft genomic sequences of plasmidless strains of serotype O1 (strain 96F) and O2β (strain RV22)
and V. ordalii. All strains harbor two chromosomes, but 775 also harbors the virulence plasmid pJM1, which carries the anguibactin-produc...
Vibrio coralliilyticus has been implicated as an important pathogen of coral species worldwide. In this study, the nearly complete genome of Vibrio coralliilyticus strain P1 (LMG23696) was sequenced and proteases implicated in virulence of the strain were specifically investigated. The genome sequence of P1 (5 513 256 bp in size) consisted of 5222...
We analysed the taxonomic position of the genus Listonella based on phylogenetic, genomic and phenotypic data. The species of the genus Listonella were nested within the genus Vibrio according to the 16S rRNA gene sequence-based phylogenetic tree. The closest neighbour of Vibrio (Listonella) anguillarum strains LMG 4437(T) and ATCC 68554 (=strain 7...
