| serratia nematodiphila sp. nov., associated symbiotically with the entomopathogenic nematode heterorhabditidoides chongmingensis (rhabditida: rhabditidae). | a novel red-pigmented, gram-negative, motile, fluorescent, rod-shaped strain, dz0503sbs1(t), with a single lateral flagellum, was isolated from the intestine of the nematode heterorhabditidoides chongmingensis. comparative 16s rrna gene sequence analysis indicated that the strain is a member of the genus serratia, sharing highest sequence similarities with serratia marcescens subsp. sakuensis jcm 11315(t) (99.8 %), s. marcescens subsp. marcescens dsm 30121(t) (99.5 %) and serratia ureilytica lmg ... | 2009 | 19578149 |
| insecticidal potency of bacterial species bacillus thuringiensis sv2 and serratia nematodiphila sv6 against larvae of mosquito species aedes aegypti, anopheles stephensi, and culex quinquefasciatus. | the tremendous worldwide efforts to isolate novel mosquito larvicidal bacteria with improved efficacy present significant promise to control vector-borne diseases of public health importance. in the present study, two native bacterial isolates, bacillus thuringiensis (bt sv2) and serratia species (sv6) were evaluated for mosquito larvicidal potential against the early fourth instar larvae of aedes aegypti, anopheles stephensi, and culex quinquefasciatus with reference to b. thuringiensis subsp. ... | 2011 | 22065062 |
| persistence of microbial communities including pseudomonas aeruginosa in a hospital environment: a potential health hazard. | the persistence of microbial communities and how they change in indoor environments is of immense interest to public health. moreover, hospital acquired infections are significant contributors to morbidity and mortality. evidence suggests that, in hospital environments agent transfer between surfaces causes healthcare associated infections in humans, and that surfaces are an important transmission route and may act as a reservoir for some of the pathogens.this study aimed to evaluate the diversi ... | 2014 | 24885173 |
| prodigiosin inhibits motility and activates bacterial cell death revealing molecular biomarkers of programmed cell death. | the antimicrobial activity of prodigiosin from serratia nematodiphila darsh1, a bacterial pigment was tested against few food borne bacterial pathogens bacillus cereus, staphylococcus aureus, pseudomonas aeruginosa and escherichia coli. the mode of action of prodigiosin was studied. prodigiosin induced bactericidal activity indicating a stereotypical set of biochemical and morphological feature of programmed cell death (pcd). pcd involves dna fragmentation, generation of ros, and expression of a ... | 2016 | 27460563 |
| in vitro antibacterial activity and mechanism of silver nanoparticles against foodborne pathogens. | biosynthesis of silver nanoparticles using planomicrobium sp. and to explore the antibacterial activity against food borne pathogenic bacteria bacillus subtilis, (3053) klebsiella planticola (2727) klebsiella pneumoniae (maa) serratia nematodiphila (caa) and escherichia coli. in the current studies, 1 mm of silver nitrate was added into 100 ml of planomicrobium sp. culture supernatant. the bioreduction of pure agno3 was characterized by uv-visible spectroscopy, x-ray diffraction analysis (xrd), ... | 2014 | 25313307 |
| enterobacillus tribolii gen. nov., sp. nov., a novel member of the family enterobacteriaceae, isolated from the gut of a red flour beetle, tribolium castaneum. | two novel gram-stain negative facultative anaerobic, motile, rod-shaped bacterial strains ig-v01(t) and ig-v01b were isolated from the gut of red flour beetles, tribolium castaneum. the 16s rrna gene sequences of strains ig-v01(t) and ig-v01b were found to have their highest sequence similarity (96.5% and 96.4%) with serratia nematodiphila dz0503sbs1(t) (enterobacteriaceae family) respectively. strains ig-v01(t) and ig-v01b share 100% 16s rrna gene sequence similarity and exhibit very similar ph ... | 2015 | 25716888 |
| genome sequence of serratia nematodiphila dsm 21420t, a symbiotic bacterium from entomopathogenic nematode. | serratia nematodiphila dsm 21420(t) (=cgmcc 1.6853(t), dz0503sbs1(t)), isolated from the intestine of heterorhabditidoides chongmingensis, has been known to have symbiotic-pathogenic life cycle, on the multilateral relationships with entomopathogenic nematode and insect pest. in order to better understanding of this rare feature in serratia species, we present here the genome sequence of s. nematodiphila dsm 21420(t) with the significance of first genome sequence in this species. | 2015 | 25444874 |
| effect of endophyte-infection on growth parameters and cd-induced phytotoxicity of cd-hyperaccumulator solanum nigrum l. | the aim of this work was to evaluate effects of endophytic bacterium inoculation on plant growth and assess the possible mechanism of endophyte in heavy metal phytoremediation. seeds of solanum nigrum l. were inoculated with endophyte serratia nematodiphila lre07 and were subjected to cd in the growing medium. cd produced a significant inhibition on plant growth and a reduction in the content of photosynthetic pigments. the inoculation of endophytic bacterium alleviated the cd-induced changes, r ... | 2012 | 22858258 |
| phytochemical constituents of fucoidan (padina tetrastromatica) and its assisted agnps for enhanced antibacterial activity. | biological synthesis of nanomaterials is a growing innovative approach and it was broadly utilised in the field of nanotechnology and nanomedicine. this study illustrates that biosynthesis of silver nanoparticles (agnps) using fucoidan extracted from seaweed padina tetrastromatica. the functional groups of extracted fucoidan were characterised by fourier transform infrared spectroscopy (ftir) and used to nps synthesis. synthesised agnps were characterised by ultraviolet-visible spectra, scanning ... | 2017 | 28476987 |
