| relationship of the luminous bacterial symbiont of the caribbean flashlight fish, kryptophanaron alfredi (family anomalopidae) to other luminous bacteria based on bacterial luciferase (luxa) genes. | flashlight fishes (family anomalopidae) have light organs that contain luminous bacterial symbionts. although the symbionts have not yet been successfully cultured, the luciferase genes have been cloned directly from the light organ of the caribbean species, kryptophanaron alfredi. the goal of this project was to evaluate the relationship of the symbiont to free-living luminous bacteria by comparison of genes coding for bacterial luciferase (lux genes). hybridization of a lux ab probe from the k ... | 1990 | 2256783 |
| vibrio bivalvicida sp. nov., a novel larval pathogen for bivalve molluscs reared in a hatchery. | three isolates were obtained from cultures of carpet shell clam (ruditapes decussatus) reared in a bivalve hatchery (galicia, nw spain) from different sources: healthy broodstock, moribund larvae and the seawater corresponding to the larval tank. all isolates were studied by a polyphasic approach, including a phylogenetic analysis based on concatenated sequences of the five housekeeping genes ftsz, gyrb, pyrh, reca and rpoa. the analysis supported their inclusion in the orientalis clade of the g ... | 2016 | 26654527 |
| vibrio crosai sp. nov., isolated from a cultured oyster crassostrea gigas. | a motile, facultative anaerobic, marine bacterial isolate (caim 1437(t)) was obtained from a cultured oyster (crassostrea gigas) in sonora, méxico. the strain was studied by a phylogenetic analysis based on sequences of the 16s rrna and five housekeeping genes, i.e. ftsz, gapa, pyrh, reca, and topa. comparison of the almost-complete 16s rrna gene sequence with those of other type strains of the genus vibrio showed a close relationship with the type strains of vibrio orientalis and vibrio rotifer ... | 2014 | 24973134 |
| denaturing gradient gel electrophoresis analyses of the vertical distribution and diversity of vibrio spp. populations in the cariaco basin. | the cariaco system is the second largest permanently anoxic marine water body in the world. its water column is characterized by a pronounced vertical layering of microbial communities. the goal of our study was to investigate the vertical distribution and diversity of vibrio spp. present in the cariaco basin waters using denaturing gradient gel electrophoresis (dgge) of pcr-amplified 16s rdna fragments. representatives of the vibrio genus were detected by nested and direct pcr in seawater at 10 ... | 2011 | 21507026 |
| identification of the genes encoding nad(p)h-flavin oxidoreductases that are similar in sequence to escherichia coli fre in four species of luminous bacteria: photorhabdus luminescens, vibrio fischeri, vibrio harveyi, and vibrio orientalis. | genes encoding nad(p)h-flavin oxidoreductases (flavin reductases) similar in both size and sequence to fre, the most abundant flavin reductase in escherichia coli, were identified in four species of luminous bacteria, photorhabdus luminescens (atcc 29999), vibrio fischeri (atcc 7744), vibrio harveyi (atcc 33843), and vibrio orientalis (atcc 33934). nucleotide sequence analysis showed fre-like flavin reductases in p. luminescens and v. fischeri to consist of 233 and 236 amino acids, respectively. ... | 1994 | 8206831 |
