| anopheles gambiae (diptera: culicidae) oviposition in response to agarose media and cultured bacterial volatiles. | anopheles gambiae s.s. giles accepted a range of agarose gels, varying from 0.5 to 8% (wt:vol), for oviposition; laid more eggs on 0.5% agarose gels than on moist filter paper or on drier agarose; and laid equal numbers of eggs on 0.5% agarose gels and distilled water. larvae hatched on agarose gel substrates and crawled onto the surface of moist agarose gels, but they tended only to burst the egg cap and remain within the egg case on drier gels. a mixture of cultured bacteria, originating from ... | 2006 | 16739407 |
| the rcsa promoter of pantoea stewartii subsp. stewartii features a low-level constitutive promoter and an esar quorum-sensing-regulated promoter. | the upstream region of the pantoea stewartii rcsa gene features two promoters, one for constitutive basal-level expression and a second autoregulated promoter for induced expression. the esar quorum-sensing repressor binds to a site centered between the two promoters, blocking transcription elongation from the regulated promoter under noninducing conditions. | 2006 | 16740966 |
| characterisation of prototype nurmi cultures using culture-based microbiological techniques and pcr-dgge. | undefined nurmi-type cultures (ntcs) have been used successfully to prevent salmonella colonisation in poultry for decades. such cultures are derived from the caecal contents of specific-pathogen-free birds and are administered via drinking water or spray application onto eggs in the hatchery. these cultures consist of many non-culturable and obligately anaerobic bacteria. due to their undefined nature it is difficult to obtain approval from regulatory agencies to use these preparations as direc ... | 2006 | 16814892 |
| molecular characterization of pantoea stewartii subsp. stewartii hrpy, a conserved response regulator of the hrp type iii secretion system, and its interaction with the hrps promoter. | pantoea stewartii subsp. stewartii is a bacterial pathogen of corn. its pathogenicity depends on the translocation of effector proteins into host cells by the hrp type iii secretion system. we previously showed by genetic analysis that the hrpx sensor kinase and the hrpy response regulator are at the head of a complex cascade of regulators controlling hrp/hrc secretion and wts effector genes. this cascade also includes the hrps response regulator and the hrpl alternative sigma factor. these regu ... | 2006 | 16816181 |
