| probiotic effect of lactobacillus sp. ds-12 in flounder (paralichthys olivaceus). | pea aphids were reared aseptically in the laboratory and fed on strains of erwinia aphidicola, erwinia herbicola, klebsiella pneumoniae, escherichia coli and bacterium w, an aphid enterobacterium, by mixing with a synthetic diet to determine whether these bacteria have pathogenicity to the insect. it turned out that er. aphidicola and er. herbicola grew in aphid gut, while k. pneumoniae, es. coli and bacterium w were effectively eliminated. in the case of er. aphidicola, ingestion of a single do ... | 1997 | 12501308 |
| cefotaxime prevents microbial contamination and improves microspore embryogenesis in wheat and triticale. | cefotaxime (100 mg/l) mitigate occasional gram negative bacterial contamination in wheat and triticale microspore culture and most importantly it increases cell growth and green plant production. isolated microspore culture is a promising option to rapidly fix the product of meiotic recombination of f1 hybrids, in the process of varietal development. clean culture and high embryogenesis rate are essential to commercial triticale and wheat microspore cultures. so, this study investigated (1) cont ... | 2013 | 23896731 |
| draft genomes, phylogenetic reconstruction, and comparative genomics of two novel cohabiting bacterial symbionts isolated from frankliniella occidentalis. | obligate bacterial symbionts are widespread in many invertebrates, where they are often confined to specialized host cells and are transmitted directly from mother to progeny. increasing numbers of these bacteria are being characterized but questions remain about their population structure and evolution. here we take a comparative genomics approach to investigate two prominent bacterial symbionts (bfo1 and bfo2) isolated from geographically separated populations of western flower thrips, frankli ... | 2015 | 26185096 |
| the phytopathogen dickeya dadantii (erwinia chrysanthemi 3937) is a pathogen of the pea aphid. | dickeya dadantii (erwinia chrysanthemi) is a phytopathogenic bacterium causing soft rot diseases on many crops. the sequencing of its genome identified four genes encoding homologues of the cyt family of insecticidal toxins from bacillus thuringiensis, which are not present in the close relative pectobacterium carotovorum subsp. atrosepticum. the pathogenicity of d. dadantii was tested on the pea aphid acyrthosiphon pisum, and the bacterium was shown to be highly virulent for this insect, either ... | 2006 | 16517643 |
| erwinia aphidicola, a new species isolated from pea aphid, acyrthosiphon pisum. | five strains of gram-negative, oxidase-negative, facultatively anaerobic, fermentative, motile, rod-shaped bacterium with the general characteristics of the family enterobacteriaceae were isolated from the gut of multiple specimens of the pea aphid. all the strains caused aphid mortality when ingested by insects via a synthetic diet. the results of biochemical tests showed that these strains are most related to erwinia herbicola and pantoea agglomerans. according to dna-dna hybridization, the fi ... | 1997 | 12501306 |
