| 6130 | 0 | 0.9586 | Characterization of the virulence, growth temperature and antibiotic resistance of the Campylobacter jejuni IAL 2383 strain isolated from humans. The objective of this study was to characterize the C. jejuni IAL2383 strain isolated from humans in Brazil. Transcripts for the racR, dnaJ and ciaB genes were found and flaA, plda and cadF genes were present in the genome and bacteria was sensitive to most of the important antimicrobials used to treat humans. C. jejuni IAL2383 is a good experimental model to analyze the interactions with cells. | 2014 | 24948944 |
| 823 | 1 | 0.9578 | Characterization of the prtA and prtB genes of Erwinia chrysanthemi EC16. Two tandem metalloprotease-encoding structural genes, prtA and prtB, were sequenced from Erwinia chrysanthemi EC16. These were highly homologous to previously reported genes from the same bacteria, as well as to three other metalloprotease-encoding genes from enteric bacteria. The three tandem prt structural genes from strain EC16 were closely linked to a cluster of genes previously found to be essential for extracellular secretion of the metalloproteases. | 1993 | 8224883 |
| 6133 | 2 | 0.9570 | Comparative genomic study of three species within the genus Ornithinibacillus, reflecting the adaption to different habitats. In the present study, we report the whole genome sequences of two species, Ornithinibacillus contaminans DSM22953(T) isolated from human blood and Ornithinibacillus californiensis DSM 16628(T) isolated from marine sediment, in genus Ornithinibacillus. Comparative genomic study of the two species was conducted together with their close relative Ornithinibacillus scapharcae TW25(T), a putative pathogenic bacteria isolated from dead ark clam. The comparisons showed O. contaminans DSM22953(T) had the smallest genome size of the three species indicating that it has a relatively more stable habitat. More stress response and heavy metal resistance genes were found in the genome of O. californiensis DSM 16628(T) reflecting its adaption to the complex marine environment. O. scapharcae TW25(T) contained more antibiotic resistance genes and virus factors in the genome than the other two species, which revealed its pathogen potential. | 2016 | 26706221 |
| 6131 | 3 | 0.9560 | Draft Genome Sequence of Eggerthia catenaformis Strain MAR1 Isolated from Saliva of Healthy Humans. Here, we report the draft genome sequence of Eggerthia catenaformis MAR1 isolated during a screen for d-cycloserine-resistant bacteria from the saliva of healthy humans. Analysis of the genome reveals that the strain has the potential to be a human pathogen and carries genes related to virulence and antibiotic resistance. | 2017 | 28705984 |
| 6135 | 4 | 0.9558 | Complete genome sequence of Bifidobacterium animalis subsp. lactis KLDS 2.0603, a probiotic strain with digestive tract resistance and adhesion to the intestinal epithelial cells. Bifidobacterium animalis subsp. lactis KLDS 2.0603 (abbreviated as KLDS 2.0603) is a probiotic strain isolated from the feces of an adult human. Previous studies showed that KLDS 2.0603 has a high resistance to simulated digestive tract conditions and a high ability to adhere to intestinal epithelial cells (Caco-2). These two characteristics are essential requirements for the selection of probiotic bacteria. To explore the stress resistance mechanism to the digestive tract environment and the adhesive proteins of this strain, in this paper, we reported the complete genome sequence of KLDS 2.0603, which contains 19,469bp and encodes 1614 coding sequences(CDSs), 15 rRNA genes, 52 tRNA genes with 1678 open reading frames. | 2016 | 26795356 |
| 822 | 5 | 0.9558 | Exoglucanase-encoding genes from three Wickerhamomyces anomalus killer strains isolated from olive brine. Wickerhamomyces anomalus killer strains are important for fighting pathogenic yeasts and for controlling harmful yeasts and bacteria in the food industry. Targeted disruption of key genes in β-glucan synthesis of a sensitive Saccharomyces cerevisiae strain conferred resistance to the toxins of W. anomalus strains BS91, BCA15 and BCU24 isolated from olive brine. Competitive inhibition of the killing activities by laminarin and pustulan refer to β-1,3- and β-1,6-glucans as the main primary toxin targets. The extracellular exoglucanase-encoding genes WaEXG1 and WaEXG2 from the three strains were sequenced and were found to display noticeable similarities to those from known potent W. anomalus killer strains. | 2013 | 23148020 |
| 5212 | 6 | 0.9554 | Draft Genome Sequences of Pseudomonas MWU13-2625 and MWU12-2115, Isolated from a Wild Cranberry Bog at the Cape Cod National Seashore. Two highly similar Pseudomonas sp. genome sequences from wetland bog soil isolates with draft genomes of ~6.3 Mbp are reported. Although the exact taxonomic placement and environmental roles of these bacteria are unclear, predicted genes for stress tolerance, antibiotic resistance, and a type VI secretion system were detected. | 2018 | 30533670 |
| 6211 | 7 | 0.9552 | Natural resistance to salmonellae in mice: control by genes within the major histocompatibility complex. Determinations of 50% lethal dose (LD50) values in H-2 congenic B10 lines showed that late-emerging resistance (postimmune response phase) to salmonellae of intermediate virulence was less in H-2b and H-2d than in H-2a, H-2k, and H-2f mice. Association of resistance to H-2 was confirmed by backcross analysis, and LD50 determinations on H-2 recombinant haplotype strains showed that resistance maps to the I-E subregion. Bacterial growth curves in liver and spleen showed that susceptible mice carried bacteria for longer in the reticuloendothelial system than did resistant mice and that susceptible mice showed greater splenomegaly. Association of resistance and susceptibility to H-2 was not different when sister transductant salmonellae expressing somatic antigens O4 and O9 were used. Thus a gene(s) within the major histocompatibility complex controls natural resistance to salmonellae in mice by influencing the ability to clear bacteria from the reticuloendothelial system in the later phase of the infection, and the immunodominant O antigen cannot be solely involved. | 1985 | 2413142 |
| 5189 | 8 | 0.9552 | Genomic analysis of halophilic bacterium, Lentibacillus sp. CBA3610, derived from human feces. BACKGROUND: Lentibacillus species are gram variable aerobic bacteria that live primarily in halophilic environments. Previous reports have shown that bacteria belonging to this species are primarily isolated from salty environments or food. We isolated a bacterial strain CBA3610, identified as a novel species of the genus Lentibacillus, from a human fecal sample. In this report, the whole genome sequence of Lentibacillus sp. CBA3610 is presented, and genomic analyses are performed. RESULTS: Complete genome sequence of strain CBA3610 was obtained through PacBio RSII and Illumina HiSeq platforms. The size of genome is 4,035,571 bp and genes estimated to be 4714 coding DNA sequences and 64 tRNA and 17 rRNA were identified. The phylogenetic analysis confirmed that it belongs to the genus Lentibacillus. In addition, there were genes related to antibiotic resistance and virulence, and genes predicted as CRISPR and prophage were also identified. Genes related to osmotic stress were found according to the characteristics of halophilic bacterium. Genomic differences from other Lentibacillus species were also confirmed through comparative genomic analysis. CONCLUSIONS: Strain CBA3610 is predicted to be a novel candidate species of Lentibacillus through phylogenetic analysis and comparative genomic analysis with other species in the same genus. This strain has antibiotic resistance gene and pathogenic genes. In future, the information derived from the results of several genomic analyses of this strain is thought to be helpful in identifying the relationship between halophilic bacteria and human gut microbiota. | 2021 | 34162403 |
| 480 | 9 | 0.9538 | Permanent draft genome sequences of cadmium-resistant isolates of Cupriavidus from soils within the Tar Creek Superfund site. Soil samples taken near the abandoned town of Picher, OK, USA, were used to enrich and isolate bacteria in the presence of cadmium. Isolates reported belong to the genus Cupriavidus. Here, we report their permanent draft sequences with an emphasis on genes conferring resistance to cadmium. | 2025 | 39589146 |
| 5889 | 10 | 0.9536 | Monitoring of Virulence Genes, Drug-Resistance in Campylobacter coli Isolated from Golden Retrievers. The investigation was performed on 75 of Golden Retriever puppies. Faecal samples were collected on the 42 day of the puppies life (con-trol). Probiotic preparation was administered on 43 day of the puppies life and 10 days after the application of the probiotic, faecal samples were collected again (on 53 day of puppies life). All isolates of Campylobacter coli isolated prior to the administration of the probiotic were found to contain the cadF gene responsible for adhesion, as well as, the flaA gene influencing motility of the examined bacteria. Significant differences (P < 0.05) were recorded only in the case of enrofloxacin. | 2016 | 30015450 |
| 6143 | 11 | 0.9535 | Paleomicrobiology to investigate copper resistance in bacteria: isolation and description of Cupriavidus necator B9 in the soil of a medieval foundry. Remains of a medieval foundry were excavated by archaeologists in 2013 in Verdun (France). Ancient workshops specialized in brass and copper alloys were found with an activity between 13th to 16th c. Levels of Cu, Zn and Pb reached 20000, 7000 and 6000 mg kg(-1) (dw), respectively, in several soil horizons. The objective of the present work was to examine the microbial community in this contaminated site. A total of 8-22 10(6) reads were obtained by shotgun metagenomics in four soil horizons. Bioinformatic analyses suggest the presence of complex bacterial communities dominated by Proteobacteria. The structure of the community was not affected by metals, contrary to the set of metal-resistance genes. Using selective media, a novel strain of Cupriavidus necator (eutrophus), strain B9, was isolated. Its genome was sequenced and a novel metal resistance gene cluster with Hg resistance genes (merRTPCA) followed by 24 copper-resistance genes (actP, cusCBAF, silP, copK1, copH4QLOFGJH3IDCBARS, copH2H1, copK2) was found. This cluster is partly homologous to the cop genes of Cupriavidus gilardii CR3 and C. metallidurans CH34. Proteomics indicated that the four copH genes were differentially expressed: CopH1 and CopH2 were mostly induced by Cd while CopH4 was highly expressed by Cu. | 2017 | 27943589 |
| 6137 | 12 | 0.9533 | Genomic and phenotypic analyses of Carnobacterium jeotgali strain MS3(T), a lactate-producing candidate biopreservative bacterium isolated from salt-fermented shrimp. Carnobacterium jeotgali strain MS3(T) was isolated from traditionally fermented Korean shrimp produced with bay salt. The bacterium belongs to the family Carnobacteriaceae, produces lactic acid and contains gene clusters involved in the production of lactate, butyrate, aromatic compounds and exopolysaccharides. Carnobacterium jeotgali strain MS3(T) was characterized through extensive comparison of the virulence potential, genomic relatedness and sequence similarities of its genome with the genomes of other Carnobacteria and lactic acid bacteria. In addition, links between predicted functions of genes and phenotypic characteristics, such as antibiotic resistance and lactate and butyrate production, were extensively evaluated. Genomic and phenotypic analyses of strain MS3(T) revealed promising features, including minimal virulence genes and lactate production, which make this bacterium a desirable candidate for exploitation by the fermented food industry. | 2015 | 25868912 |
| 479 | 13 | 0.9532 | Genome sequences of Methylobacterium and Methylorubrum isolates from Cd-contaminated soils in the Tar Creek Superfund site. Soil bacteria were isolated from the Tar Creek Superfund site in the presence of cadmium. Eight of these strains belong to the genus Methylobacterium, whereas one strain belongs to the genus Methylorubrum. Here, we report drafts of their genome sequences and highlight cadmium-resistance genes required in an exceptionally contaminated environment. | 2025 | 39835800 |
| 6129 | 14 | 0.9531 | Yersinia ruckeri Infection and Enteric Redmouth Disease among Endangered Chinese Sturgeons, China, 2022. During October 2022, enteric redmouth disease (ERM) affected Chinese sturgeons at a farm in Hubei, China, causing mass mortality. Affected fish exhibited characteristic red mouth and intestinal inflammation. Investigation led to isolation of a prominent bacterial strain, zhx1, from the internal organs and intestines of affected fish. Artificial infection experiments confirmed the role of zhx1 as the pathogen responsible for the deaths. The primary pathologic manifestations consisted of degeneration, necrosis, and inflammatory reactions, resulting in multiple organ dysfunction and death. Whole-genome sequencing of the bacteria identified zhx1 as Yersinia ruckeri, which possesses 135 drug-resistance genes and 443 virulence factor-related genes. Drug-susceptibility testing of zhx1 demonstrated high sensitivity to chloramphenicol and florfenicol but varying degrees of resistance to 18 other antimicrobial drugs. Identifying the pathogenic bacteria associated with ERM in Chinese sturgeons establishes a theoretical foundation for the effective prevention and control of this disease. | 2024 | 38781928 |
| 3049 | 15 | 0.9527 | Characterisation of plasmids purified from Acetobacter pasteurianus 2374. Four cryptic plasmids pAP1, pAP2, pAP3, and pAP4 with their replication regions AP were isolated from Gram-negative bacteria Acetobacter pasteurianus 2374 and characterised by sequence analyses. All plasmids were carrying the kanamycin resistance gene. Three of four plasmids pAP2, pAP3, and pAP4 encode an enzyme that confers ampicillin resistance to host cells. Moreover, the tetracycline resistance gene was identified only in pAP2 plasmid. All plasmids are capable to coexist with each other in Acetobacter cells. On the other hand, the coexistence of more than one plasmid is excluded in Escherichia coli. The nucleotide sequence of replication regions showed significant homology. The nucleotide and protein sequence analyses of resistance genes of all plasmids were compared with transposons Tn3, Tn10, and Tn903 which revealed significant differences in the primary structure, however no functional changes of gene were obtained. | 2003 | 14511653 |
| 507 | 16 | 0.9524 | Tellurite resistance and reduction by obligately aerobic photosynthetic bacteria. Seven species of obligately aerobic photosynthetic bacteria of the genera Erythromicrobium, Erythrobacter, and Roseococcus demonstrated high-level resistance to tellurite and accumulation of metallic tellurium crystals. High-level resistance without tellurite reduction was observed for Roseococcus thiosulfatophilus and Erythromicrobium ezovicum grown with certain organic carbon sources, implying that tellurite reduction is not essential to confer tellurite resistance. | 1996 | 16535446 |
| 8439 | 17 | 0.9523 | Comparative genomics analysis and virulence-related factors in novel Aliarcobacter faecis and Aliarcobacter lanthieri species identified as potential opportunistic pathogens. BACKGROUND: Emerging pathogenic bacteria are an increasing threat to public health. Two recently described species of the genus Aliarcobacter, A. faecis and A. lanthieri, isolated from human or livestock feces, are closely related to Aliarcobacter zoonotic pathogens (A. cryaerophilus, A. skirrowii, and A. butzleri). In this study, comparative genomics analysis was carried out to examine the virulence-related, including virulence, antibiotic, and toxin (VAT) factors in the reference strains of A. faecis and A. lanthieri that may enable them to become potentially opportunistic zoonotic pathogens. RESULTS: Our results showed that the genomes of the reference strains of both species have flagella genes (flaA, flaB, flgG, flhA, flhB, fliI, fliP, motA and cheY1) as motility and export apparatus, as well as genes encoding the Twin-arginine translocation (Tat) (tatA, tatB and tatC), type II (pulE and pulF) and III (fliF, fliN and ylqH) secretory pathways, allowing them to secrete proteins into the periplasm and host cells. Invasion and immune evasion genes (ciaB, iamA, mviN, pldA, irgA and fur2) are found in both species, while adherence genes (cadF and cj1349) are only found in A. lanthieri. Acid (clpB), heat (clpA and clpB), osmotic (mviN), and low-iron (irgA and fur2) stress resistance genes were observed in both species, although urease genes were not found in them. In addition, arcB, gyrA and gyrB were found in both species, mutations of which may mediate the resistance to quaternary ammonium compounds (QACs). Furthermore, 11 VAT genes including six virulence (cadF, ciaB, irgA, mviN, pldA, and tlyA), two antibiotic resistance [tet(O) and tet(W)] and three cytolethal distending toxin (cdtA, cdtB, and cdtC) genes were validated with the PCR assays. A. lanthieri tested positive for all 11 VAT genes. By contrast, A. faecis showed positive for ten genes except for cdtB because no PCR assay for this gene was available for this species. CONCLUSIONS: The identification of the virulence, antibiotic-resistance, and toxin genes in the genomes of A. faecis and A. lanthieri reference strains through comparative genomics analysis and PCR assays highlighted the potential zoonotic pathogenicity of these two species. However, it is necessary to extend this study to include more clinical and environmental strains to explore inter-species and strain-level genetic variations in virulence-related genes and assess their potential to be opportunistic pathogens for animals and humans. | 2022 | 35761183 |
| 6151 | 18 | 0.9523 | Novel arsenic hyper-resistant bacteria from an extreme environment, Crven Dol mine, Allchar, North Macedonia. Novel hyper-resistant bacteria were isolated from the Crven Dol mine (Allchar, North Macedonia), arsenic-rich extreme environment. Bacteria were recovered from a secondary mineral mixture, an alteration of hydrothermal realgar rich in arsenates (pharmacolite, hornesite, and talmessite). The sample was recovered from the dark part of the mine at 28 m depth. Three bacterial strains and a bacterial consortium were isolated for their capacity to survive exposure to 32 g/L (209 mM) of arsenite, and 176 g/L (564 mM) of arsenate. The 16S rRNA gene analysis identified bacterial isolates as Stenotrophomonas sp. and two Microbacterium spp. This analysis also revealed that bacterial consortium comprise two Bacteriodetes exhibiting similarity to Olivibacter ginsengisoli and to uncultured bacterium, and one γ-proteobacteria with similarity to Luteimonas sp. Among all isolates Stenotrophomonas sp. exhibited the highest tolerance to As compound as well as the capacity to accumulate As inside the cells. Analysis of genes involved in As-resistance showed that recovered isolates possess the genes encoding the ArsB, Acr3(1) and Acr3(2) proteins, indicating that at least a part of their resistance could be ascribed to As-efflux systems described in isolates obtained from human-polluted environments. | 2021 | 32712355 |
| 545 | 19 | 0.9522 | Characterization of the organic hydroperoxide resistance system of Brucella abortus 2308. The organic hydroperoxide resistance protein Ohr has been identified in numerous bacteria where it functions in the detoxification of organic hydroperoxides, and expression of ohr is often regulated by a MarR-type regulator called OhrR. The genes annotated as BAB2_0350 and BAB2_0351 in the Brucella abortus 2308 genome sequence are predicted to encode OhrR and Ohr orthologs, respectively. Using isogenic ohr and ohrR mutants and lacZ promoter fusions, it was determined that Ohr contributes to resistance to organic hydroperoxide, but not hydrogen peroxide, in B. abortus 2308 and that OhrR represses the transcription of both ohr and ohrR in this strain. Moreover, electrophoretic mobility shift assays and DNase I footprinting revealed that OhrR binds directly to a specific region in the intergenic region between ohr and ohrR that shares extensive nucleotide sequence similarity with so-called "OhrR boxes" described in other bacteria. While Ohr plays a prominent role in protecting B. abortus 2308 from organic hydroperoxide stress in in vitro assays, this protein is not required for the wild-type virulence of this strain in cultured murine macrophages or experimentally infected mice. | 2012 | 22821968 |
