519110.8621Draft genome sequences data of Mammaliicoccus lentus isolated from horse farm soil. Mammallicoccus lentus is a member of the commensal microflora of the Staphylococcaceae family, which colonizes the skin of several species of farm animals, including poultry and dairy animals (Huber et al., 2011; Zhang et al., 2009). The study of the members of the Staphylococcaceae family, such as the Mammaliicoccus genus, isolated from various sources is of great importance for agriculture and public health as contributes to the accumulation of knowledge and understanding of the mechanisms of antibiotic resistance gene transmission among bacterial pathogens. This thesis is supported by recent studies showing that some members of the Mammallicoccus genus serve as a reservoir of virulence and antibiotic resistance genes and may also be a source of horizontal gene transfer (Saraiva et al., 2021). Here, we present a draft genome sequence of Mammallicoccus lentus strain PVZ.22 from a horse farm soil sample. The sequencing was performed on the Illumina MiSeq platform. The genome was assembled using the Geneious software package. The genome contains 2,802,282 bp with a total of 2805 genes, 8 perfect and 12 strict AMR genes and 58 tRNAs genes.202338075610

81040.8542Draft genome sequencing and functional annotation and characterization of biofilm-producing bacterium Bacillus novalis PD1 isolated from rhizospheric soil. Biofilm forming bacterium Bacillus novalis PD1 was isolated from the rhizospheric soil of a paddy field. B. novalis PD1 is a Gram-positive, facultatively anaerobic, motile, slightly curved, round-ended, and spore-forming bacteria. The isolate B. novalis PD1 shares 98.45% similarity with B. novalis KB27B. B. vireti LMG21834 and B. drentensis NBRC 102,427 are the closest phylogenetic neighbours for B. novalis PD1. The draft genome RAST annotation showed a linear chromosome with 4,569,088 bp, encoding 6139 coding sequences, 70 transfer RNA (tRNA), and 11 ribosomal RNA (rRNA) genes. The genomic annotation of biofilm forming B. novalis PD1(> 3.6@OD(595nm)) showed the presence of exopolysaccharide-forming genes (ALG, PSL, and PEL) as well as other biofilm-related genes (comER, Spo0A, codY, sinR, TasA, sipW, degS, and degU). Antibiotic inactivation gene clusters (ANT (6)-I, APH (3')-I, CatA15/A16 family), efflux pumps conferring antibiotic resistance genes (BceA, BceB, MdtABC-OMF, MdtABC-TolC, and MexCD-OprJ), and secondary metabolites linked to phenazine, terpene, and beta lactone gene clusters are part of the genome.202134537868
519250.8536Genome Sequencing Analysis of a Rare Case of Blood Infection Caused by Flavonifractor plautii. BACKGROUND Flavonifractor plautii belongs to the clostridium family, which can lead to local infections as well as the bloodstream infections. Flavonifractor plautii caused infection is rarely few in the clinic. To understand better Flavonifractor plautii, we investigated the drug sensitivity and perform genome sequencing of Flavonifractor plautii isolated from blood samples in China and explored the drug resistance and pathogenic mechanism of the bacteria. CASE REPORT The Epsilometer test method was used to detect the sensitivity of flavonoid bacteria to antimicrobial agents. PacBio sequencing technology was employed to sequence the whole genome of Flavonifractor plautii, and gene prediction and functional annotation were also analyzed. Flavonifractor plautii displayed sensitivity to most drugs but resistance to fluoroquinolones and tetracycline, potentially mediated by tet (W/N/W). The total genome size of Flavonifractor plautii was 4,573,303 bp, and the GC content was 59.78%. Genome prediction identified 4,506 open reading frames, including 9 ribosomal RNAs and 66 transfer RNAs. It was detected that the main virulence factor-coding genes of the bacteria were the capsule, polar flagella and FbpABC, which may be associated with bacterial movement, adhesion, and biofilm formation. CONCLUSIONS The results of whole-genome sequencing could provide relevant information about the drug resistance mechanism and pathogenic mechanism of bacteria and offer a basis for clinical diagnosis and treatment.202438881048

518970.8528Genomic 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.202134162403
538180.8524Draft genome sequence of Staphylococcus urealyticus strain MUWRP0921, isolated from the urine of an adult female Ugandan. Staphylococcus urealyticus bacteria are pathogenic among immune-compromised individuals. A strain (MUWRP0921) of Staphylococcus urealyticus with a genome of 2,708,354 bp was isolated from Uganda and carries genes that are associated with antibiotic resistance, including resistance to macrolides (erm(C) and mph(C')), aminoglycosides (aac(6")-aph(2")), tetracyclines (tet(K)), and trimethoprim (dfrG).202438078696
519090.8517Genomic Analysis of Cronobacter condimenti s37: Identification of Resistance and Virulence Genes and Comparison with Other Cronobacter and Closely Related Species. Cronobacter condimenti are environmental commensals that have not been associated with any clinical infections. To date, they are the least understood and described Cronobacter species within the genus. The objective of this study was to use a draft genome sequence (DGS) of the Cronobacter condimenti strain s37 to screen for genes encoding for antibiotic resistance, virulence, response to environmental stress, and biofilm formation. The strain was isolated in Poland from commercial small radish sprouts. This is the second genome of this species available in the GenBank database. The comparative genome analysis (cgMLST) of C. condimenti s37 with other Cronobacter spp. including the pathogenic species C. sakazakii and the plant-associated closely related genera Franconibacter and Siccibacter was also performed. The assembled and annotated genome of the C. condimenti s37 genome was 4,590,991 bp in length, with a total gene number of 4384, and a GC content of 55.7%. The s 37 genome encoded for genes associated with resistance to stressful environmental conditions (metal resistance genes: zinc, copper, osmotic regulation, and desiccation stress), 17 antimicrobial resistance genes encoding resistance to various classes of antibiotics and 50 genes encoding for the virulence factors. The latter were mainly genes associated with adhesion, chemotaxis, hemolysis, and biofilm formation. Cg-MLST analysis (3991 genes) revealed a greater similarity of C. condimenti s37 to S. turicensis, F. pulveris, and C. dublinensis than to other species of the genus Cronobacter. Studies on the diversity, pathogenicity, and virulence of Cronobacter species isolated from different sources are still insufficient and should certainly be continued. Especially the analysis of rare strains such as s37 is very important because it provides new information on the evolution of these bacteria. Comparative cgMLST analysis of s37 with other Cronobacter species, as well as closely related genera Franconibacter and Siccibacter, complements the knowledge on their adaptability to specific environments such as desiccation.202439201307
491100.8509Class II broad-spectrum mercury resistance transposons in Gram-positive bacteria from natural environments. We have studied the mechanisms of the horizontal dissemination of a broad-spectrum mercury resistance determinant among Bacillus and related species. This mer determinant was first described in Bacillus cereus RC607 from Boston Harbor, USA, and was then found in various Bacillus and related species in Japan, Russia and England. We have shown that the mer determinant can either be located at the chromosome, or on a plasmid in the Bacillus species, and is carried by class II mercury resistance transposons: Tn5084 from B. cereus RC607 and B. cereus VKM684 (ATCC10702) and Tn5085 from Exiguobacterium sp. TC38-2b. Tn5085 is identical in nucleotide sequence to TnMERI1, the only other known mer transposon from Bacillus species, but it does not contain an intron like TnMERI1. Tn5085 is functionally active in Escherichia coli. Tn5083, which we have isolated from B. megaterium MK64-1, contains an RC607-like mer determinant, that has lost some mercury resistance genes and possesses a merA gene which is a novel sequence variant that has not been previously described. Tn5083 and Tn5084 are recombinants, and are comprised of fragments from several transposons including Tn5085, and a relative of a putative transposon from B. firmus (which contains similar genes to the cadmium resistance operon of Staphylococcus aureus), as well as others. The sequence data showed evidence for recombination both between transposition genes and between mer determinants.200111446519
3022110.8505Sequencing and characterization of pBM400 from Bacillus megaterium QM B1551. Bacillus megaterium QM B1551 plasmid pBM400, one of seven indigenous plasmids, has been labeled with a selectable marker, isolated, completely sequenced, and partially characterized. A sequence of 53,903 bp was generated, revealing a total of 50 predicted open reading frames (ORFs); 33 were carried on one strand and 17 were carried on the other. These ORFs comprised 57% of the pBM400 sequence. Besides the replicon region and a complete rRNA operon that have previously been described, several interesting genes were found, including genes for predicted proteins for cell division (FtsZ and FtsK), DNA-RNA interaction (FtsK, Int/Rec, and reverse transcriptase), germination (CwlJ), styrene degradation (StyA), and heavy metal resistance (Cu-Cd export and ATPase). Three of the ORF products had high similarities to proteins from the Bacillus anthracis virulence plasmid pXO1. An insertion element with similarity to the IS256 family and several hypothetical proteins similar to those from the chromosomes of other Bacillus and Lactococcus species were present. This study provides a basis for isolation and sequencing of other high-molecular-weight plasmids from QM B1551 and for understanding the role of megaplasmids in gram-positive bacteria. The genes carried by pBM400 suggest a possible role of this plasmid in the survival of B. megaterium in hostile environments with heavy metals or styrene and also suggest that there has been an exchange of genes within the gram-positive bacteria, including pathogens.200314602653

5185150.8501Genomic characterisation of nasal isolates of coagulase-negative Staphylococci from healthy medical students reveals novel Staphylococcal cassette chromosome mec elements. Coagulase-negative staphylococci (CoNS) are a diverse group of Gram-positive bacteria that are part of the normal human microbiota. Once thought to be non-pathogenic, CoNS has emerged in recent years as opportunistic pathogens of concern particularly in healthcare settings. In this study, the genomes of four methicillin-resistant CoNS isolates obtained from the nasal swabs of healthy university medical students in Malaysia were sequenced using the Illumina short-read platform. Genome sequencing enabled the identification of the four isolates as Staphylococcus warneri UTAR-CoNS1, Staphylococcus cohnii subsp. cohnii UTAR-CoNS6, Staphylococcus capitis subsp. urealyticus UTAR-CoNS20, and Staphylococcus haemolyticus UTAR-CoNS26. The genome of S. cohnnii UTAR-CoNS6 harboured the mecA methicillin-resistance gene on a Staphylococcal cassette chromosome mec (SCCmec) element similar to SCCmec type XIV (5 A) but the SCCmec cassettes identified in the other three CoNS genomes were novel and untypeable. Some of these SCCmec elements also encoded heavy metal resistance genes while the SCCmec type XIV (5 A) variant in S. cohnii UTAR-CoNS6 harboured the complete ica operon, a known virulence factor that functions in biofilm formation. In S. cohnii UTAR-CoNS6, the macrolide resistance genes msrA and mphC along with copper and cadmium resistance genes were located on a 26,630 bp plasmid, pUCNS6. This study showcased the diversity of CoNS in the nasal microbiota of medical students but the discovery of novel SCCmec elements, various antimicrobial and heavy metal resistance along with virulence genes in these isolates is of concern and warrants vigilance due to the likelihood of spread, especially to hospitalised patients.202540595841
5383160.8501Draft genome sequence of Acinetobacter haemolyticus strain MUWRP1017 isolated from the pus of a female inpatient at Bwera General Hospital in Uganda. The bacterium Acinetobacter haemolyticus, with a genome size of 3.4 Mb, was isolated from a pus swab of a wound on the left lower limb above the ankle joint of a female patient.

6088170.8501Complete Genome of Achromobacter xylosoxidans, a Nitrogen-Fixing Bacteria from the Rhizosphere of Cowpea (Vigna unguiculata [L.] Walp) Tolerant to Cucumber Mosaic Virus Infection. Achromobacter xylosoxidans is one of the nitrogen-fixing bacteria associated with cowpea rhizosphere across Africa. Although its role in improving soil fertility and inducing systemic resistance in plants against pathogens has been documented, there is limited information on its complete genomic characteristics from cowpea roots. Here, we report the complete genome sequence of A. xylosoxidans strain DDA01 isolated from the topsoil of a field where cowpea plants tolerant to cucumber mosaic virus (CMV) were grown in Ibadan, Nigeria. The genome of DDA01 was sequenced via Illumina MiSeq and contained 6,930,067 nucleotides with 67.55% G + C content, 73 RNAs, 59 tRNAs, and 6421 protein-coding genes, including those associated with nitrogen fixation, phosphate solubilization, Indole3-acetic acid production, and siderophore activity. Eleven genetic clusters for secondary metabolites, including alcaligin, were identified. The potential of DDA01 as a plant growth-promoting bacteria with genetic capabilities to enhance soil fertility for resilience against CMV infection in cowpea is discussed. To our knowledge, this is the first complete genome of diazotrophic bacteria obtained from cowpea rhizosphere in sub-Saharan Africa, with potential implications for improved soil fertility, plant disease resistance, and food security.202439278894
490180.8496Mercuric resistance genes in gram-positive oral bacteria. Mercury-resistant bacteria isolated from the oral cavities of children carried one of two types of merA gene that appear to have evolved from a common ancestor. Streptococcus oralis, Streptococcus mitis and a few other species had merA genes that were very similar to merA of Bacillus cereus strain RC607. Unlike the B. cereus RC607 merA gene, however, the streptococcal merA genes were not carried on Tn5084-like transposons. Instead, comparisons with microbial genomic sequences suggest the merA gene is located on a novel type II transposon. Coagulase-negative staphylococci and Streptococcus parasanguis had identical merA genes that represent a new merA variant.200415251199
6082190.8492Complete genome sequence of the probiotic candidate strain Lacticaseibacillus rhamnosus B3421 isolated from Panax ginseng C. A. Meyer in South Korea. OBJECTIVES: Lacticaseibacillus rhamnosus is a widely recognized probiotic bacteria with therapeutic applications in human and animal health. The L. rhamnosus B3421 strain, isolated from Panax ginseng, has been reported to be associated with antioxidant and anti-inflammatory properties, supporting its functional potential. We sequenced and analyzed the genome of L. rhamnosus B3421 to evaluate its probiotic potential for human healthcare and animal applications, focusing on genomic features related to safety and functionality. DATA DESCRIPTION: In this study, we isolated L. rhamnosus B3421 from Panax ginseng C. A. Meyer (Ginseng) and performed whole-genome sequencing. The genome of L. rhamnosus B3421 consists of 3,000,051 base pairs (bp) with a guanine + cytosine (G + C) content of 46.70%. It encodes 59 transfer RNAs, 15 ribosomal RNAs, and 2,807 coding sequences (CDSs). Of these CDSs, 99.13% (2,758 proteins) were assigned to functional categories in the Clusters of Orthologous Group (COGs) classification system, while 49 proteins remained uncharacterized. Our genome analysis identified no antibiotic resistance (ABR) or antimicrobial resistance (AMR) genes, indicating that L. rhamnosus B3421 is a safe probiotic bacterium with minimal risk of contributing to the horizontal transfer of antibiotic resistance within the gut microbiome. Additionally, the genome contains genes associated with the ggmotif (PF10439), Enterocin X chain beta, and Carnocin CP52, as identified through BAGEL4 analysis, along with 24 other genes related to reductase or peroxidase activities. These genes may confer competitive advantages against pathogenic bacteria and oxidative stress. Our findings highlight the probiotic potential of L. rhamnosus B3421 and its prospective applications in promoting human and animal health.202540877785
