| a bacillus thuringiensis isolate possessing a spore-associated filament. | we report on a novel bacterium, isolated during a screen for environmental isolates of bacillus thuringiensis, that possesses a novel filamentous structure. nucleotide sequence from the isolate's 16s rrna gene places the bacterium unambiguously within the bacillus thuringiensis/bacillus cereus group. phase-contrast and electron microscopy indicate the presence of both a parasporal body and a long filament which are retained after sporulation. the filament is shown to consistently arise from the ... | 2003 | 14629020 |
